What kind of soldering iron is needed for soldering microcircuits. Soldering iron temperature for soldering microcircuits

Working temperature embossed soldering iron to metal that solder

The main task of the soldering iron is the hour of soldering of the various contacts in the field in the melted solder and applied on the plate. Naturally, for which the temperature of the soldering iron is needed, as a rule, the lower temperature of the melting of glass materials. To improve the fact that for various metals and their alloys it can be strongly cracked, let out tools with different tension, like building work in different parameters. Even if it is high, the indicators are so shkidlivi for the yakіsnogo zadnannya, like they are low. Only in the first moment I’ll bring everything to melting, I’ll solder it to such a state, if it’s already impossible to work, and in the other, it’s not possible to melt normally for welding.

All reasons lead to the fact that the temperature of the soldering iron tip can be optimal. For the skin condition, there are different options to help you achieve the best results. In order to determine that the temperature of the soldering iron tip when soldering is at fault, the glass material, the type of wires, contact materials and other parameters are insured.

Temperature of the soldering tip

The working temperature of the soldering iron of the skin process is adjusted okremo. Under an hour of soldering of the same type of contacts with different solders of the same solder, it is allowed to set the same parameters in the tool. In other situations, bring up the soldering iron to change the necessary characteristics. For work with soldering solders, the temperature of the soldering iron for soldering is always to blame, but the temperature of the melting solder is lower. The retail price can be small, only 5-10 degrees. With modern technology, such indications are easily accessible, such as a tension regulator and an accurate heating sensor.

Melting point of rare metals

Don't ever have to rely on standard soldering with ready-made solder grades. Sometimes it can be brought to practice with non-standard metals. Don't ever give a guaranteed result, but sometimes the best solution for fixing the details. Here it is necessary to know how the temperature of the soldering iron tip is necessary for robots, and also for what kind of melting of metals, with which the robot is being conducted.

If on the right there is a need to make contacts or roses of singing parts, then this information becomes more important, lower technical data solder. The heating temperature of the soldering iron is responsible for reaching such values, so that the contact can be melted. Tse means that it is guilty of but equal magnitude, when it is melting, or else overdo it. With the improvement of the coldness of the tightness of the soldering irons, it is far from possible. Deyaki see the metal is impossible to melt with a soldering iron. Varto check the technical characteristics of the tool with the parameters of metal or alloy.

Ways to remove the required temperature

The temperature of the soldering iron tip is 100 watts. From one side, it is not possible to overestimate the maximum value in case of a total draw, and from the other side, it is impossible to reduce it so that it was increased on the same level. If you need a lower value for this parameter for soldering, try replacing the tool. The temperature of the soldering iron tip of 60 watts will be lower than its counterpart by 100 watts, so a good method is given for selecting the required temperature. For a long time, the very same was the main one, the shards of modern models with parameters that are regulated, appeared notably recently. Not a lot of technique for those who need to bathe a sprat of soldering irons. It also gives an accurate regulation, if you want more fluctuations and approximate values.

The installation of a pressure regulator helps solve the problem of low temperatures and practically any model. The regulator can be installed practically any model. Vіn pracyuvatime z vіdnosnimi znachennâ v svoєmu range. For example, if the range of regulation is between 0 and 100%, then the temperature of the soldering iron tip is 40 watts at half a turn of the regulator knob, it will indicate the temperature of heating the soldering iron by 20 watts. At 25% the value is more than 10 watts and so on. The regulator can reduce the exchange rate, for example, up to 50%. You can't go lower than vin.

Buying a model with temperature control. The regulator is automatically set up, optimizing for a specific model, which can be found directly in the annex building, becoming a modern solution. Zavdyaki youmu, the temperature of the soldering iron for soldering microcircuits can be regulated with accuracy right up to 1 degree Celsius. The versatility of such soldering irons is lower than in standard models; best choice.

No more than a manual method of regulation is to draw a sting in advance of the advance. For the cob, the tool reaches its maximum, and then it is necessary to bud, until the wine cools down to the required value. Cooling is required properly, so I need to choose the whole value to really wink for which cooling accessory, so that I can show the exact parameters.

Setting for temperature control

The temperature of heating the tip of the soldering iron is assigned for the help of special vibrators, or, as they are called, thermometers for the soldering iron. These attachments are based on a thermocouple, which shows the exact value with a change of up to a few degrees. There are a lot of models on the market, which can show the temperature in degrees Celsius or Fahrenheit. May all models at the same time create a digital scale for displaying data. The thermocouple can be used for an hour and needs to be replaced, but it also allows you to work with any types of soldering irons.

Krim okremikh vimiruvachiv, more є vbudovani options. The stench is to go as soon as possible with a soldering iron, which is more convenient for robots with one tool. Tse pomitno vplyvaetsya on the varity of the viroba, but here we do not blame the problems due to the frequent replacement of the thermocouple. Another way to designate is to use a multimeter. The methodology is even wider, so like fakhіvtsіv z soldering plant є takі fit. The accuracy of the assigned value depends on the specific model.

Visnovok

For home soldering, it is most common to use smart approximate values ​​of the sting. What is enough quiet vipadkіv, if there is no great viability of the day. If you talk about professional soldering and about working with microcircuits, then here it is already necessary to improve accuracy. While for popular types of materials, the values ​​given and the temperature of the soldering iron tip for POS 61 can be looked at directly from the table, then for non-standard solutions, it is necessary to select the values ​​independently.

The temperature of the soldering iron when soldering with soft solder, setting the thermometer and tip activator

It does not mean that the temperature of the soldering iron is universal and that soldering iron is suitable for absolutely all types. It is rich to lie in the form of solder, in view of the fact that the master works with the same materials, and also in the form of purposes, as in the case of wines.

And in general, the choice of optimal temperature is not so simple on the right. Sound the tip of the soldering iron, the dots are fired, the docks won’t be able to melt the solders. Ale in deyakih vipadkah needs more fine tuning.

Dekilka soldering rules

There is one unbreakable rule: the temperature of the soldering iron is to blame for the melting temperature of the solder.

Moreover, the solder material can be melted even more before it fills the empty spaces and evenly spreads over the surface.

If the tip of the soldering iron appears to be overheated, the solder will oxidize and the soldering seam will not be removed. Before speech, oxides can appear on the soldering iron itself, and in order to get them, fahivtsy to please the activator of the sting - it’s actually more corisna river.

And if the tip of the soldering iron will not just overheat, but burn out, then the soldering material will stop burning on the new trim. “Cold” soldering (if the temperature of the soldering iron tip is less than optimal) will not give an accurate result.

Even if the solder material does not melt to a plain mill, the place of soldering becomes dull and short, and the joint is not necessary.

And one more important rule, more important for any soldering: the temperature of the elements themselves, which are soldered, is invariably due to the same.

Various solders

All the diversity of solders can be divided into two categories:

• refractory;
• fusible (soft).

To the category of soft lie solder, which can have a melting point of up to 400 ℃ and a low mechanical strength (support up to seven kilograms per square millimeter). Їx can be melted with a soldering iron.

Marking of such solder has the abbreviation POS and numbers, which indicate a specific type of tin. For the butt of the varto, put on an arc of expansion solder material POS-61, operating at a temperature of 190 to 260 ° Celsius.

POS-61 and other soft tin-lead solders, zokrema, vicorist for radio installation. Vzagali pid hour of work s other boards need to be done carefully.

A sharp heating and temperature rise are more likely than unique, and the frivolity of a soldering iron is not guilty of exceeding more than two seconds. Such objects, such as integrated microcircuits and field-operated transistors, are especially worthy.

To remove special powers to the warehouse of tin-lead solders, bismuth, cadmium, antimony and other metals can be introduced. Use low-melting solder in liquid rods, pastes, darts, powders, stitches, as well as tubes with a diameter of 1 to 5 mm with rosin in the middle.

Among the varieties of such solders, one can see brandy Felder and AIM.

And one more addendum: fakhіvtsі recommend not to pick up metal boxes, krishechki, plaques to save solders. Solders can stick to the metal - the result is rosin porridge on the walls, which will not be comfortable to work with.

Solid solders are characterized by the fact that they vibrate high-quality seams. In radio installation robots, the stench is richer, lower fusible. Moreover, you can see two subgroups of solid solders - copper-zinc and silver.

The first victories are used for soldering bronze, steel, brass and other metals that have a high melting point. Tsіkavo, scho їhnіy color to fall in vіd vіdsotka instead of zinc. And the melting temperature, let's say, solder PMC-42 is 830 ℃.

Srіbnі pripoї mаut, mabut, even more mіtsnіst. Їх zastosovuyt, mainly for soldering copper-brass and silver-plated brass. The melting temperature of such solders is in the range of 720 to 830 ℃. Under an hour of work with such materials, put on a palnik.

Melting of various materials

At the master, you can blame the need for soldering midi - mov, for example, you can go about the trumpets of scorching or otherwise, from colorful metal.

It is possible to use a soldering iron with a middyu and її different alloys, zastosovuychi different solders like soft, so hard. In this case, the temperature of soldering the middle elements with soft solders should be 250-300 ℃, and with hard solders - 700-900 ℃.

And what can be the temperature of the soldering iron tip, as if you need to solder, let's say, polypropylene products? At to this particular type the optimum temperature will be +260 ℃, and the reasonable allowable range is from +255 to +280 ℃.

However, if you overheat the soldering iron more than 271 ℃ and change the hour of heating the tool, then the surface of the soldering zone will warm up much more in the interior. Tse means that as a result of the brewing, the spitting will appear even thinner.

Korisn_ pristroї for vimіryuvannya

Practice shows that the temperature of the tip of a vicorous soldering iron is correct, then, chill, soldering matima, a characteristic mirror glare.

First of all, the porosity and dullness of the zone soldering are evidence of those that the procedure was carried out not very well.

Finding the optimal melting point can be done by way. For which you need special soldering iron heating regulators (laboratory transformers). Є, vtim, і the simplest way to adjust the temperature is to change the temperature of the sting.

But this method, perhaps, is only relevant for self-made fittings for soldering. In whatever mood, the master can be recognized in advance, at a certain temperature, or at a certain temperature, the solder stings a mirror glare.

Having mastered this knowledge, you can find out the right help for the job.

For the obvious financial possibilities of the varto, a special thermometer (sensor) for the soldering iron is needed, which will freeze and calibrate the working temperature of the tool.

Such sensors at once can be done in abundance. I be-yakoy bazhayuchomu pridbati will need a model online or offline in a difficult warehouse. The stinks of robbing the swidky and accurate temperature gauge of the soldering iron tip for the help of a thermocouple (thermoelectric convertor).

When choosing such a thermometer, you should pay attention to such characteristics, such as zdatnіst, range of vimіryuvannya (for example, vіn can be from 0 to 700 ℃), accuracy, dimensions, possible life.

However, simply controlling the temperature is not enough. It is important that the soldering iron saves a constant, with possible haircuts, the voltage in the thread - that is the necessary special stabilizer.

Such an attachment can be prepared independently - with free access, simple schemes. In addition, at the same time soldering irons and soldering stations are already being used with a stabilizer.

And a lot of professional soldering stations allow you to accurately set the temperature and required mode soldering, we will forgive the pushing of the buttons or the switching of the toggle switch. It is important to simplify the process of work and allow you to be sure of a good result.

TOP-5 soldering irons for soldering microcircuits and radio components

Soldering and invisible part of the repair of possession of microcircuits of that creation. It is worth to complete the folding process, which requires the presence of a special possession, because the work is being carried out here with detailed details. The soldering iron for microcircuits is remembered depending on what is needed for soldering darts. The difference is smaller, the lower models are larger for larger operations, and the sting is also thinner. Can zustrіchatisya options with special types of sharpening, yakі razrakhovanі most importantly for vipoyuvannya.

An electric soldering iron for microcircuits is a necessary tool for a master to repair that amateur radio equipment. Models can be in a different price segment with different characteristics. For some reason, there will be a hand tool that will allow you to apply a thin ball of solder and heat parts for soldering and soldering these circuits. A lot of different and high-profile ones are assigned to one type of work.

Features of soldering irons for microcircuits

One of the main features of such models is the shape of the sting. The tip itself is the main working tool. Fallow in the form of this form and other features can be understood, as the very pracyuvateme attachments and for some purposes of wine assignments. The form is not a single parameter, which is seen by a soldering iron for electronics in the middle. Rozmir is becoming one more factor that sees the same type of outbuildings on others. A small soldering iron for microcircuits allows you to carry out basic operations for work with them, although large standard models seem to be rough for such a work. Tse is indicated by the tightness of the virobu. For the skin appearance, the tension may be weak, so it worked out for melting the contacts, but the soldering iron didn’t change anything.

See soldering irons for electronics

The main thing that helps to separate soldering irons for electronics into different types is the type of heating element that they use. For the rest of the hour, the technology of variation allows the release of impersonal varieties, which are considered one type of one for the characteristics.

Nichrome

The main heating element in such soldering irons is nichrome drіt. The material is good to conduct electric impulses, which allows you to heat the sting to the required temperature to finish the shvidko. Simple models make a spiral, as it is wound on the body, so as not to conduct electricity. Sob drіt without spending heat, yoga is placed to insulators. Similar models are most likely to be found in a hand-made non-professional vikoristanny.

Noodles:

• Soldering iron for radio components with a nichrome heating element for a long time;
• Spiral quickly burns out and її to bring minyati.

Advantages:

• The simplicity of the vikoristannya;
• Nevibaglivist to zovnishnіh factors;
• High impact resistance.

Ceramic

Soldering iron for soldering microcircuits of telephones with a ceramic heating element with a special shear, which connects to the contacts to give a voltage. Zavdyaki d_ї naprugi ceramics are heated up to the required temperature.

Advantages:

• Thin soldering iron for microcircuits with ceramics;
• Shvidko heated up to the required temperature.

Nedoliki

• High shillnіst up to mechanical poshkodzhen;
• It is impossible to replace the sting, as if it were to be mischievous.

induction

The point soldering iron of the induction type can have all the necessary capacities for soldering microcircuits. The new one has a feromagnetic coating, as if it were safe for adoption magnetic field on the sting, as well as the coil of the inductor. In particular, those who, when the maximum temperature is reached, are heated. If the temperature starts to drop, the electrical supply is restored. Tse zumovleno ferromagnetic powers pokrittya.

Advantages:

• The manifestation of automatic play;
• Saving energy;
• Nevibaglivost in operation.

Nedoliki

• In order to choose the optimal value of the heating temperature, change the tips, the scales of this parameter are adjusted according to the Curie point.

Impulse

The main feature of this model is a frequency converter, which can be used as a high-frequency transformer. The frequency rises slowly, but in a day's time it drops to the working value. The sting here is part of an electric stake. It is connected to the secondary winding. This ensures the passage of the great streams through the winding, which gives the shortest possible hour of heating. The heating function is activated only when the button on the soldering iron is pressed. If you let it in, then you will reach it.

Advantages:

• Garniy soldering iron for microcircuits is heated up in the meantime;
• The versatility of zastosuvannya, like great, so small details.

Noodles:

• A pulse soldering iron for soldering microcircuits cannot be soldered for trial work.

Characteristics of popular models

A tip for a soldering iron for microcircuits is not the only one, on which the varto should be respected. Here are selected the main characteristics of the most popular models that are victorious for robots with microcircuits.

Wimogi to soldering irons for radio components

For an average soldering iron, the power of a soldering iron can be close to 10 watts. The smaller the parameter, the more chances to keep the radio elements safe and sound. It is not recommended to use more difficult tools, so one of the main ones could be a reasonable selection of the parameter to be quiet, for which there will be attachments. The intensity of a soldering iron for soldering microcircuits can reach up to 40 W, but professionals can work with a 4 W soldering iron, which is especially important for details.

The sting can be mіtsnim and be cleansed well. As a rule, it is necessary to finish thin grains, to that the presence of a militant material is obov'yazkovoy umovoy dovogostrokovo work. Here, materials for jal are often victorious, as they are rarely used in great soldering irons, which are still maddened by the vimogami.

The presence of additional functions, turn-on buttons, rotting on the case, special covers and other speeches is determined by this, for which area a soldering iron is assigned. Everything that makes it easier to work with the most significant additions to the singing medium will be binding for specific models, where the function is required.

The cost is more important than professional outbuildings;

How to choose a hand soldering iron?

Considering how to choose a soldering iron for microcircuits, carefully consider the following parameters:

• Tension. The lower the tension of the virobu, the easier it is to practice, the chips due to the high temperature are risky to burn the circuit. 10 W є optimal values ​​for robots.
• voltage. The most common voltage is 220 V, you can use a standard microcircuit. Soldering irons have a life block, which reduces the voltage to 36 or 12V. Such a rank, the best choice will be an outbuilding from such a block of living.
• Tovshchina pressed. Dilyanki for soldering can be divided into ten parts of a millimeter. Here there are cone-shaped stings, the number of such to become 1 millimeter and less, which can be deposited in sharpening.
• Temperature controller. For rich models, the presence of a thermostat becomes an acceptable addition. It is even more important to keep the same temperature for an hour. Dopovnennya help to reach the required result.

Virobniki

On the current market of products, it is possible to pick up goods from the following varieties:

• Rexant;
• matrix;
• Sparta;
• Topex;
• Well.

Visnovok

Soldering irons for soldering microcircuits can be seen up to the narrow-profile outbuildings, but the profile is even wider. Fahіvtsі s repair, lovers of electronics, those people who solder the microcircuits themselves, cannot do without a special soldering iron. The versatility of products to the market with different parameters only confirms the demand for the sector.

What do you know about the procedure?

The temperature of soldering is an important moment for a robotic soldering iron, which is a kind of deposit for some kind of metal. The Danish pokaznik is guilty of buti vishchim for a similar pokaznik of the re-melting of tinol. In some cases, the indicator can be found between the liquidus line and the solidus line.

Spiryuchis on theory, solder is guilty of buti povnіstu melting until the moment, how vіn zapovnit promіzhok and rozpodіlitsya in z'єdnanny pіd influx of capillary forces. In connection with cym, the temperature of the liquidus tinol can be the lowest, as it is necessary for such a procedure, as a high-temperature soldering. At its core, all the details are due to heat up to the right temperature or higher.

We cannot be blamed for the fact that all the internal and external parts of the parts are heated up to just the right temperature. The speed of heating, the amount of heat transfer, the mass of metal parts, as well as the coefficient of thermal expansion of the metal, which is soldered - all these factors, as they signify in the details of the distribution of heat.

At the time of the medium heating of the parts, the temperature rose unevenly, the temperature of the external surfaces is significantly higher than the temperature of the internal ones. Under the hour of full heating and equal distribution of heat, the distribution of thermal energy in the soldered node is increased more evenly.

Diffusion, as well as the development of tinol by stretching soldering

Under the hour of wetting the metal, which will start, for the help of the melted solder, it may be possible to separate the base metal with the tinol or the diffusion of the components with the tinol into the base metal. In addition to everything, diffusion may be the most effective solution in that case, like tinol together with the base metal is similar to chemical warehouse.

On the expansion of that diffusion, there may be such factors as:

• The temperature of the loading of materials;
• Trivality soldering;
• The geometry of the space for the metal that rolls over, the shards out of the way show the area of ​​the main material, which flows into the tinol;
• Chemical warehouse.

In single fluctuations, by stretching the soldering through the mass diffusion of the tinol between the grains of the main material, there is a rise in the material, which should be deposited under the internal stresses. Overworld diffusion of tinol in the base metal with great flexibility can be added to the mechanical and physical power of the metal.

In this order, thin parts of the main material are the most irritating zone of the soldered half. In each region, through erosion, crystallized shells can be established. If it is significant that the expansion of the base metal with tinol changes the temperature of the liquid liquid, it can lead to insufficient filling of the gap between the details.

For a change in diffusion, or a difference, there is a sprinkling of alloys, as if they are stagnant like tinols. Solders acquire a rare consistency when the temperature is reached and lower than the temperature of the liquidus. Zavdyaks of solder similar to the warehouse of high-temperature soldering viroblyaetsya successfully also for quiet environments, if the temperature of the soldering metal did not reach the liquid line.

The temperature of the smd-components

The lower switch allows you to change the thermal input of the component in the smd-board, thereby lowering the temperature of the soldering tool. Under the hour of trying to repeat the methods of replacing the components in the lower part of the building, change or turn off the warping of the smd-payment, as a whole it can be done through one-sided heating for additional hot air.

In addition, other boards, wickered on the basis of ceramics, before the soldering procedure, require smooth forward heating due to the sensitivity of these materials to temperature changes.

Relying on the method of supplying thermal energy, you can see infrared and convection lower heating. The first pristosuvannya often folded z kіlkoh quartz lamps, yakі mаyut clearly vyrazhene chervone svіchennya. If there are convection outbuildings, then stench can form a path of stasis of primus convection.

Look at the smd-components to cry out, and in the minds of the infusion of vibrational instability (during mechanical shocks) can crackle. Another minus of smd-components is intolerance to overheating for an hour of soldering, through which microcracks are often blamed, it is practically impossible to mark them. Best of all, perhaps, you can help those who know about cracks in smd-components under the hour of operation. You can check the visibility of cracks in smd parts with the help of a great multimeter.

In this way, you can put smd-details behind an additional soldering station, as well as a soldering iron. Pevna part of the soldering iron is solid, so the soldering of the components is simpler with a soldering station with a stabilized temperature. However, even though there is no soldering station, you can change the power supply for an additional soldering iron, including one for an additional regulator. Without a regulator for a powerful soldering iron, the temperature of the tip (sting) reaches a temperature of 400 gr. oskanik pіd hour of work with smd-components is guilty of becoming 260-270 gr. Z.

The optimal temperature for heating the soldering iron, and also the need for tightness for an hour of manual soldering - indicators that lie in design features a soldering iron, which was fixed by him. In robots with lead-free solders of a tubular shape, they can melt the melting point of 217-227 gr. The minimum indicator for heating the soldering iron tip is 300 gr. Z.

By stretching the soldering, it is necessary to uniquely overcome the overheating soldering iron tip, as well as the dry tip on the metal. Most often, work with solders, which do not include lead in the warehouse, and traditional tinols, most suitable for heating the soldering iron tip to a temperature of 315-370 gr. Z.

In some situations, when soldering smd-components, the results can be up to an hour of short-hour heating (trivality of the soldering iron tip is up to 0.5 seconds), as well as when heating the soldering iron tip to an indication of 340 to 420 gr. Z.

The order of soldering smd-components

The order of soldering smd-components:

1. Look at one of the contact maidanchiks on the back. For this, give a sufficient amount of tinol for a distant molding of the zholobnik.
2. Dalіd installation of the smd-component on the CP.
3. At the next stage, attach the smd-component to the additional tweezers, and immediately put the soldering iron tip on it, thereby ensuring the one-hour contact of the soldering iron tip with the sighting of the smd-component, as well as the KP.
4. Fasten the short-hour soldering with a pull of 0.5-1.5 seconds. If you sting prystosuvannya, then it can be brought out.
5. Give high-temperature soldering another reason: when the tip is attached, you will ensure one-hour contact of the tip with the output and KP.
6. Dali z protilezhno ї sting soldering iron side next file tinol pіd kutom 45 ° to KP, as well as the removal of the component.

Chotiri secrets - a pledge of successful soldering

Іsnuє chotiri the secrets of the yakіsny vikonannya soldering, further trivaloї exploitation of the details. Let's take a look at their report.

Main yakіsnі spoluki:

1. The correctness of stosuvannya solder and flux in the solder;
2. Cleanliness of the soldering iron tip, and heat the steps of yogo heating;
3. Clean surfaces that are soldered by metals during the first hour of the procedure;
4. Correctness of heating, sufficient heating of the working zone of parts.

As it became clear, depending on the temperature of the heating of parts, as well as the stage of heating the soldering iron, it is too late. Also, you should know the melting point of some tin-lead solders.

Solder melting point

The knowledge of technological warehouse soldering allows the solder to store the details for a long time, which is the best quality for the right professional. In this way, high-temperature soldering will show impressive performance.

Starry look micro soldering irons in various types

The designated area of ​​​​stowing a microsoldering iron

From the development of electronic industry came small-sized conductor parts, microcircuits, which are mounted on other boards. For ease of installation of microcircuits and other radio components on a different board, I needed a soldering iron for soldering microcircuits of low intensity and with a thin tip. Of course, when designing such a soldering iron, the following numbers were examined:

• Shvidke brought їх at the working camp;
• Reduced savings in electricity;
• Increased space of the sting to the heating element;
• Sob not to damage the wiring of microcircuits or other details, not to damage the streak paths on the board, a small soldering iron is needed, the tip can be thin, to finish the mіtsnim and save your power at sharp temperature drops.

Soldering irons for microcircuits are responsible for vibrating soldering, so many microcircuits and other conductor parts are sensitive to sudden changes and high temperatures, to a surge of static electricity. At the moment of long-term heating, the stench can irrevocably change its technical characteristics, or it will explode.

With the development of these projects, modern technologies were developed for the production of synthetic materials, installed in the design of microsoldering irons of different brands. Modern micro-soldering irons do not work in the mode of continuous heating, in sets with a soldering station, the stench automatically adjusts the required temperature, which saves electricity and prolongs the resource of the robot.

Soldering iron on a diamond-filled single-crystal

In some models, like a heating element, the vicorous elements are synthetically vibrated on the conductors of monocrystals (Diamant), the size of the ribs of which is not more than 1 mm. One of the streak-conducting lines in this variant is a metal shear of a sting, which is heated, the surface of which is fastened to one of the faces of a monocrystal. Another strum-conducting line is fixed to the protilene face of the crystal.

The design of the heating crystal microsoldering iron

Strumoprovidnі lived krіplyaetsya to the crystal eftektіchny solder, scho folded proportions of many components. The soldering process takes place in a vacuum chamber at 1.33 x 10-2 Ra and a temperature of 950 C. This technology makes it possible to reach the CCD of the heating element up to 98%;

Soldering irons with graphite powder

This soldering iron for microcircuits, as a heating element, contains graphite powder, which fills the hermetically sealed space between the shear tip in the center of that outer casing. This design does not have such Swedish effect heating like in the front, it cannot be ensured by the economic mode of saving electricity.

Nichrome microsoldering irons

These models may have a classic version of the design - a sting shear is inserted into a thermo-resistant, dielectric tube with a heat conductor, and a spiral is wound on the outer side from a nichrome droth. For heat concentration, the drіt leaks through ceramic insulators, reducing heat losses, the winding is covered with a metal casing.

Elements of nichrome heating

The advantages of such designs are at an inexpensive price, simplicity and costliness of the design, as short as it is possible to indicate inadequacy - the spiral quickly burns out and heats up for a long time. That's why soldering irons do not vikoristovuyutsya on the ferrule lines, they are rationally stuck on their minds for carrying out short-hour work, depending on the criteria for price and quality.

The ceramic heating element of the soldering iron has a thin cylindrical shape of the shear, brushing aluminum oxide, which allows it to heat up and maintain high temperatures.

Construction of ceramic heater

The shearing cuts into a heat-resistant plate, which is laminated, a tungsten spiral is processed on a printer. Until the end of the spiral, the wires of the introduction of contacts are soldered. Everything is inserted into a metal tube with a handle;

Elements of ceramic heating

Different nozzles are put on the end of the ceramic rod for soldering microcircuits or other elements of other boards.

The advantage of ceramic models is important for the fastening of the opening and the regulation of the temperature, to a small extent it is possible to insert a thin shear and a whisker nozzle with a diameter of the opening of the bottom.

Induction microsoldering iron

The cutting tips of these microsoldering irons are covered with ferromagnetic materials, inserted into the coil of the inductor, which creates a magnetic field, under the influx of this field, a strum is induced in the heart, which plays the haircut.

Construction of induction heater

When the temperature is set, the ferromagnetic ball of the file loses its power, heating is applied. When the power of the ferromagnetic ball is cooled, the induction jet heats up the shear again. In this way, the temperature of the soldering iron tip is required.

The advantages of this type are the warming up and the automatic maintenance of the stability of the set temperature. It is necessary to indicate that for the skin temperature interval it is necessary to put a double tip with a ball of ferromagnetic coating. It is possible to find the Curie point, if the magnetic field is turned on.

Criteria for choosing a soldering iron

Nasampered, you need to be appointed, how often and how often the robots are victorious with this tool. For soldering microcircuits on other boards, insurance is required technical characteristics:

• The pressure is recommended to be low - 5-11W, with low pressures, soldering for radio components is safer;
• great value maє the shape of the sting - for the vipoyuvannya of the visnovkіv is more flatter than the form, the more maє the greater area and the more rozіgrіvaє delyanka with tin on the stream-carrying road of the drukovanoї plate. For soldering, the microcircuit needs to be embossed in a cone-shaped form, in order to heat it up at the same time at the same time. Therefore, it is recommended to buy soldering irons with replacement tips;

Replaceable shear tips

• For sensitive microcircuits and other elements to higher temperatures and sharp changes of vicorist, soldering irons are connected through a voltage changeover, adjustable in the ranges of 12 to 36 Art.

Soldering station

For which vicorous soldering stations, stinks can be safely regulated by the voltage, lowering the tension and heating temperature. For some models, the heating buttons and temperature indication are installed in the soldering iron handle.

Residual welding can be done in the following way: for welding lines it is necessary to use soldering stations with long-term soldering irons, which will change the heating temperature quickly. Models on a diamond monocrystal or ceramic are ideally suited. The high versatility of such varieties pays off with high productivity. For butt robots to radioamators, it is rational to buy a ceramic or nichrome micro-soldering iron, the price of them is significantly less. If you solder richly, as they allow financial possibilities, you can add an induction ceramic option.

Select a soldering iron for soldering radio components, wires: TOP-5 models

The leather type of soldering is sometimes observed in other different varieties, which are poured into the vibrator of the instrument, for the help of which procedures will be carried out. A good soldering iron for soldering pipes may not be suitable for work with radio components. That is why it is necessary to know how to choose the right soldering iron for robots with microcircuits and other radio elements. Before the parameters of the building, special aids hang, shards of broken technology can harm the details themselves. Sensitive elements are especially appreciated, as they can withstand static stresses, high temperatures and other features of the work.

The robot with radio components transmits that it is necessary to carry out operations with other elements. The stench is more richly melted and for their processing it is required significantly less energy. Vikonannya procedures with such thin elements will require special care and preparation. It’s worth it as a choice of the right element, and the second is the master. Here you will need exact details and the appearance of fine details. A good tool here is becoming less and less supplementary to all fahivtsya. But it will be easier to get a little knowledgeable person with a special soldering iron for these purposes to work with a robot for the obviousness of a good tool.

Wimogi to soldering irons for soldering radio components

In order to select a soldering iron for a specific method, it is necessary to protect all the features of the selected one directly.

What kind of soldering iron is needed for soldering microcircuits: soldering technology

In radioelectronics, it is often used, which is due to the need to carry out other repair and repair work, de standing in front of the master, such a soldering iron is needed for soldering microcircuits. Golovna Vіdminnіst prilada vіd standard tse dosit thin sting. For the additional unique and specific design of the soldering iron, you can do it right and solder thinner wires without harming the structural basis of the microcircuit. What is necessary for soldering a microcircuit with a soldering iron, before choosing an accessory, we will carefully consider the technical design features of the soldering iron. The prilad is to blame for the mother’s thin sting, as well as the regulation of temperature for an hour of work.

Features of the technical characteristics of the soldering iron

We encourage you to learn about the main principles and criteria for choosing soldering irons for professional and jewelry work with soldering microcircuits, as well as jewelry and expensive items. We will help you to know about soldering iron soldering technology, as well as a number of technical nuances.

• For the greater world, the design solution of the heating element may have other significance for the master. Fakhivtsev will have to choose an attachment, depending on the outrageous criteria for working with microcircuits. Choosing soldering irons with spirals, you take into account the three-month period of heating the attachment and cooling it down more often. Ceramic soldering irons can be swidkist diy, but there are also risks of mechanical poshkodzhen, which is not good for the microcircuit case. In this situation, the master is recommended to choose a soldering iron that can have a spiral-like base. In this way, you can achieve the accuracy of the work carried out without damaging the basis of the microcircuit.
• The parameters of tightness. Now it is necessary to complete the task, as tightness requires a soldering iron for soldering microcircuits. Fahіvtsі recommend prilad low pressure not more than 10 watts. Remember, what will be the lower showman, how effective will be the robot in the process of soldering. If you have an expert opinion, then you need a soldering iron, with a pressure parameter of 10 Volts, for less information, the best indicator will be a pressure of 4 Volts. A low-power soldering iron reduces the risk of damage and ensures the necessary minimum capacity and reliability of wires on the microcircuit. You may need a soldering iron with high minds of exhaustion only in that case, as the microcircuit is out of tune, and it is necessary to carry out the wiring. For the repair of heavily damaged diggers, a sting was made, that the shape of the shoulder blades looks like it warms up the sprat of darts. In general, the shortest option for the designation of tightness will be the choice of tool, which may be the mode of thermoregulation.
• If you want to know how to properly solder microcircuits with a soldering iron, you should respect that the minimum attachment is not guilty of mother strum with high displays, otherwise there is a risk of non-acid soldering. Even if we use the traditional measure of 220 volts, then there is a chance to remove indirect guidance, and the microcircuit itself will be greatly damaged. The best option there will be a soldering iron with a voltage of 36 volts or 12 volts. Today, pickers are completed with blocks, which reduce the pressure with a path of transformation in the mesh.
• The design is sorry. This is an important working process of carrying out a similar robotic soldering. How to practice with a soldering iron, choosing the optimal mode of the tip, in this case, the construction of the tip with a diameter of no more than 3 mm. If you take a sting larger and lower than 3 mm, then you do not need to see the wire as well, as a result of the darts, so that you should be between the contacts of the flooring of the miserable grain, so that you can wind the 3 mm sting will be rich, then you will only have to reach the necessary parameter when choosing the necessary parameter tasks how to solder correctly. soldering iron pay. Most of the selections include a soldering iron kit, a sprat of saw tips, as a rule, the set includes 2 types of tips with different diameters.
• Parameter of firmness jala. This is an important moment of the working process of preparing the soldering iron to work. Obviously, the best and correct option to choose would be a heat-resistant material, but the maestro should be able to choose the right price for that quality. Return for help to fakhіvtsіv and take additional help from the choice of the necessary accessory for working with microcircuits.

All soldering irons and other soldering irons are used exclusively for soldering microcircuits, like making planar wires. That is why the legs are ruffled from the sides in the main body. Further, for the soldering of BGA microcircuits, it is necessary to fix that the contacts are soldered under the cases of the main structural elements, so soldering irons are not suitable for this, and here it is necessary to bend more folded and expensive.

Soldering stations - what varto to choose the equipment for soldering microcircuits?

Deyakі vvazhayut, scho soldering stations, tse those that are necessary for soldering microcircuits. For such a big thought, the soil can be made in order to say that the same soldering will be done to a high equal vikonnannya. Soldering stations are equipped with everything necessary, so that the work efficiency will be higher, and the efficiency of soldering microcircuits will be pleasant. Only one, ale, tse dorognecha obladnannya. If you are planning to start repairing microcircuits in your home minds, then it’s enough to buy the simplest soldering iron, which needs an hour at a time. If you are planning to develop a business from the repair of microcircuits, and you have a regular cycle of repair work, in this case, you will be assisted by an exhaustive soldering station with current characteristics.

Dodatkove possession

In order to ensure the highest quality of soldering of the most compact microcircuits in radio electronics, it is necessary to use not only special accessories, but also additional devices. How so vikoristovuyutsya:

• Technological tweezers (sold in special stores), necessary for handling and supporting contacts.
• Shmatochki miniature, necessary for remote insulation and defective wires.
• A file, or a small drink, is necessary for cleaning the sting, so that for cleaning that moon.
• Empty construction grey, with a hospitable tip (possible in the form of a syringe), for safe application to the surface of the flux.
• Awl technically, with a gostry tip.
• Below you can choose the best clerical option.

Dodatkovo is necessary to ensure the security and comfort of the working place. Obov'yazykovo vikoristovuyemo akіsnu system osvelennya, de nayavnіst dim lamps will be obov'yazkovo criterion of brightness robit. Do not forget to ventilate the room, and also do the necessary minimum for the help of electrical safety, fire safety. On the market there are different variants of soldering irons, starting from those found in China and ending with the best ones and the old ones, like those made in the countries of the European Union. All products are certified, have passed the required minimum quality control and are recommended to be stationed at the borders of the Soviet Union.

How to choose temperature for soldering?

The temperature of soldering is an important moment for a robotic soldering iron, which is a kind of deposit for some kind of metal. The Danish pokaznik is guilty of buti vishchim for a similar pokaznik of the re-melting of tinol. In some cases, the indicator can be found between the liquidus line and the solidus line.

Spiryuchis on theory, solder is guilty of buti povnіstu melting until the moment, how vіn zapovnit promіzhok and rozpodіlitsya in z'єdnanny pіd influx of capillary forces. In connection with cym, the temperature of the liquidus tinol can be the lowest, as it is necessary for such a procedure, as a high-temperature soldering. At its core, all the details are due to heat up to the right temperature or higher.

We cannot be blamed for the fact that all the internal and external parts of the parts are heated up to just the right temperature. The speed of heating, the amount of heat transfer, the mass of metal parts, as well as the coefficient of thermal expansion of the metal, which is soldered - all these factors, as they signify in the details of the distribution of heat.

At the time of the medium heating of the parts, the temperature rose unevenly, the temperature of the external surfaces is significantly higher than the temperature of the internal ones. Under the hour of full heating and equal distribution of heat, the distribution of thermal energy in the soldered node is increased more evenly.

Diffusion, as well as the development of tinol by stretching soldering

Under the hour of wetting the metal, which will start, for the help of the melted solder, it may be possible to separate the base metal with the tinol or the diffusion of the components with the tinol into the base metal. In addition, diffusion may be the most effective solution in that case, as tinol together with the main metal is similar to a chemical warehouse.

On the expansion of that diffusion, there may be such factors as:

• The temperature of the loading of materials;
• Trivality soldering;
• The geometry of the space for the metal that rolls over, the shards out of the way show the area of ​​the main material, which flows into the tinol;
• Chemical warehouse.

In single fluctuations, by stretching the soldering through the mass diffusion of the tinol between the grains of the main material, there is a rise in the material, which should be deposited under the internal stresses. Overworld diffusion of tinol in the base metal with great flexibility can be added to the mechanical and physical power of the metal.

In this order, thin parts of the main material are the most irritating zone of the soldered half. In each region, through erosion, crystallized shells can be established. If it is significant that the expansion of the base metal with tinol changes the temperature of the liquid liquid, it can lead to insufficient filling of the gap between the details.

For a change in diffusion, or a difference, there is a sprinkling of alloys, as if they are stagnant like tinols. Solders acquire a rare consistency when the temperature is reached and lower than the temperature of the liquidus. Zavdyaks of solder similar to the warehouse of high-temperature soldering viroblyaetsya successfully also for quiet environments, if the temperature of the soldering metal did not reach the liquid line.

The temperature of the smd-components

The lower switch allows you to change the thermal input of the component in the smd-board, thereby lowering the temperature of the soldering tool. Under the hour of trying to repeat the methods of replacing the components in the lower part of the building, change or turn off the warping of the smd-payment, as a whole it can be done through one-sided heating for additional hot air.

In addition, other boards, wickered on the basis of ceramics, before the soldering procedure, require smooth forward heating due to the sensitivity of these materials to temperature changes.

Relying on the method of supplying thermal energy, you can see infrared and convection lower heating. The first pristosuvannya often folded z kіlkoh quartz lamps, yakі mаyut clearly vyrazhene chervone svіchennya. If there are convection outbuildings, then stench can form a path of stasis of primus convection.

Look at the smd-components to cry out, and in the minds of the infusion of vibrational instability (during mechanical shocks) can crackle. Another minus of smd-components is intolerance to overheating for an hour of soldering, through which microcracks are often blamed, it is practically impossible to mark them. Best of all, perhaps, you can help those who know about cracks in smd-components under the hour of operation. You can check the visibility of cracks in smd parts with the help of a great multimeter.

In this way, you can put smd-details behind an additional soldering station, as well as a soldering iron. Pevna part of the soldering iron is solid, so the soldering of the components is simpler with a soldering station with a stabilized temperature. However, even though there is no soldering station, you can change the power supply for an additional soldering iron, including one for an additional regulator. Without a regulator for a powerful soldering iron, the temperature of the tip (sting) reaches a temperature of 400 gr. oskanik pіd hour of work with smd-components is guilty of becoming 260-270 gr. Z.

The optimal temperature for heating the tip of the soldering iron, as well as the need for tightness for an hour of manual soldering - indications, yak lie in the design features of the soldering iron, zavdannya, yak vin vykonuє. In robots with lead-free solders of a tubular shape, they can melt the melting point of 217-227 gr. The minimum indicator for heating the soldering iron tip is 300 gr. Z.

By stretching the soldering, it is necessary to uniquely overcome the overheating soldering iron tip, as well as the dry tip on the metal. Most often, work with solders, which do not include lead in the warehouse, and traditional tinols, most suitable for heating the soldering iron tip to a temperature of 315-370 gr. Z.

In some situations, when soldering smd-components, the results can be up to an hour of short-hour heating (trivality of the soldering iron tip is up to 0.5 seconds), as well as when heating the soldering iron tip to an indication of 340 to 420 gr. Z.

The order of soldering smd-components

The order of soldering smd-components:

1. Look at one of the contact maidanchiks on the back. For this, give a sufficient amount of tinol for a distant molding of the zholobnik.
2. Dalіd installation of the smd-component on the CP.
3. At the next stage, attach the smd-component to the additional tweezers, and immediately put the soldering iron tip on it, thereby ensuring the one-hour contact of the soldering iron tip with the sighting of the smd-component, as well as the KP.
4. Fasten the short-hour soldering with a pull of 0.5-1.5 seconds. If you sting prystosuvannya, then it can be brought out.
5. Give high-temperature soldering another reason: when the tip is attached, you will ensure one-hour contact of the tip with the output and KP.
6. Dali z protilezhno ї sting soldering iron side next file tinol pіd kutom 45 ° to KP, as well as the removal of the component.

Chotiri secrets - a pledge of successful soldering

Іsnuє chotiri the secrets of the yakіsny vikonannya soldering, further trivaloї exploitation of the details. Let's take a look at their report.

Main yakіsnі spoluki:

1. The correctness of stosuvannya solder and flux in the solder;
2. Cleanliness of the soldering iron tip, and heat the steps of yogo heating;
3. Clean surfaces that are soldered by metals during the first hour of the procedure;
4. Correctness of heating, sufficient heating of the working zone of parts.

As it became clear, depending on the temperature of the heating of parts, as well as the stage of heating the soldering iron, it is too late. Also, you should know the melting point of some tin-lead solders.

Solder melting point

The knowledge of technological warehouse soldering allows the solder to store the details for a long time, which is the best quality for the right professional. In this way, high-temperature soldering will show impressive performance.

4 ways to get the required temperature of the soldering iron

It is very important for someone to know that it is necessary for otrimannya okіsnoї soldering during installation of radio components, so that the temperature of the tip of the soldering iron matches the working temperature of the solder. In different brands, solder won't blow. If you overheat the tip of the soldering iron, the solder will oxidize and the soldering will be insufficient. In addition, the tip of the soldering iron burns quickly at this point, and the solder ceases to burn on the new edge. As if the soldering may have a mirror glare after reaching it, and you can take it off only for the same temperature. So, for the widest brand of solder POS-61, the soldering temperature is 190 ... 260 ° C. The recommended temperature for soldering microcircuits is 235±5 °C, the trivality of the troch is more than 2 s.

When buying the simplest cheap soldering iron for a voltage of 220 V, as a rule, it is said that the wines overheat and solder badly. You can solve this problem with chotirma paths.

Method 1. Just as the soldering iron may have a sting near the shear, which is fixed on the body behind the additional screw (Fig. 1), then by adjusting the length of the shear in the heater, you can easily smoothly change the temperature. However, not all soldering irons are capable of such a design of fastening, and this method may be unacceptable.

Method is different. Can be speeded up with LATR or transformer more introduced. In this mode, the temperature is regulated by a change in the voltage that is applied to the heating winding.

Method 3rd. After heating the soldering iron, an additional resistor (rheostat) is switched on. With this, the tension of the resistor can be the same, like that of a soldering iron, and the nominal value of the support is selected for the selection of the required temperature. Such a dodatkovy resistor may be large in size and warm, which is not handy.

Method 4th. The electronic regulator, Fig. 2, allows you to smoothly change (by changing the resistor R2) the heating temperature in the boundaries. Priya may without a transformer that small dimensions, which allow you to place it in the support of the soldering iron. The circuit is not critical to the types of parts, and її adjusting the value of the resistor R4 (with a zero value of R2) to reduce the maximum voltage on the heating. The soldering iron, which is connected, can be attenuated from 15 to 300 W, and when replacing diodes VD1 ... VD4 with a larger stream - up to 1000 W.

In case, like a soldering iron, the voltage is lowered to the lower nominal voltage (48 or 36 V), a transformer is needed, which reduces the voltage, and the voltage can be reduced to the circuit of the electronic regulator. In order to save її practicality, it is necessary to change the nominal value of the resistor R1 in proportion to the input voltage

The temperature of soldering is an important moment for a robotic soldering iron, which is a kind of deposit for some kind of metal. The Danish pokaznik is guilty of buti vishchim for a similar pokaznik of the re-melting of tinol. In some cases, the indicator can be found between the liquidus line and the solidus line.

Spiryuchis on theory, solder is guilty of buti povnіstu melting until the moment, how vіn zapovnit promіzhok and rozpodіlitsya in z'єdnanny pіd influx of capillary forces. In connection with cym, the temperature of the liquidus tinol can be the lowest, as it is necessary for such a procedure, as a high-temperature soldering. At its core, all the details are due to heat up to the right temperature or higher.

We cannot be blamed for the fact that all the internal and external parts of the parts are heated up to just the right temperature. The speed of heating, the amount of heat transfer, the mass of metal parts, as well as the coefficient of thermal expansion of the metal, which is soldered - all these factors, as they signify in the details of the distribution of heat.

At the time of the medium heating of the parts, the temperature rose unevenly, the temperature of the external surfaces is significantly higher than the temperature of the internal ones. Under the hour of full heating and equal distribution of heat, the distribution of thermal energy in the soldered node is increased more evenly.

Diffusion, as well as the development of tinol by stretching soldering

Under the hour of wetting the metal, which will start, for the help of the melted solder, it may be possible to separate the base metal with the tinol or the diffusion of the components with the tinol into the base metal. In addition, diffusion may be the most effective solution in that case, as tinol together with the main metal is similar to a chemical warehouse.

On the expansion of that diffusion, there may be such factors as:

• The temperature of the loading of materials;
• Trivality soldering;
• The geometry of the space for the metal that rolls over, the shards out of the way show the area of ​​the main material, which flows into the tinol;
• Chemical warehouse.

In single fluctuations, by stretching the soldering through the mass diffusion of the tinol between the grains of the main material, there is a rise in the material, which should be deposited under the internal stresses. Overworld diffusion of tinol in the base metal with great flexibility can be added to the mechanical and physical power of the metal.

In this order, thin parts of the main material are the most irritating zone of the soldered half. In each region, through erosion, crystallized shells can be established. If it is significant that the expansion of the base metal with tinol changes the temperature of the liquid liquid, it can lead to insufficient filling of the gap between the details.

For a change in diffusion, or a difference, there is a sprinkling of alloys, as if they are stagnant like tinols. Solders acquire a rare consistency when the temperature is reached and lower than the temperature of the liquidus. Zavdyaks of solder similar to the warehouse of high-temperature soldering viroblyaetsya successfully also for quiet environments, if the temperature of the soldering metal did not reach the liquid line.

The temperature of the smd-components

The lower switch allows you to change the thermal input of the component in the smd-board, thereby lowering the temperature of the soldering tool. Under the hour of trying to repeat the methods of replacing the components in the lower part of the building, change or turn off the warping of the smd-payment, as a whole it can be done through one-sided heating for additional hot air.

In addition, other boards, wickered on the basis of ceramics, before the soldering procedure, require smooth forward heating due to the sensitivity of these materials to temperature changes.

Relying on the method of supplying thermal energy, you can see infrared and convection lower heating. The first pristosuvannya often folded z kіlkoh quartz lamps, yakі mаyut clearly vyrazhene chervone svіchennya. If there are convection outbuildings, then stench can form a path of stasis of primus convection.

Look at the smd-components to cry out, and in the minds of the infusion of vibrational instability (during mechanical shocks) can crackle. Another minus of smd-components is intolerance to overheating for an hour of soldering, through which microcracks are often blamed, it is practically impossible to mark them. Best of all, perhaps, you can help those who know about cracks in smd-components under the hour of operation. You can check the visibility of cracks in smd parts with the help of a great multimeter.

In this way, you can put smd-details behind an additional soldering station, as well as a soldering iron. Pevna part of the soldering iron is solid, so the soldering of the components is simpler with a soldering station with a stabilized temperature. However, even though there is no soldering station, you can change the power supply for an additional soldering iron, including one for an additional regulator. Without a regulator for a powerful soldering iron, the temperature of the tip (sting) reaches a temperature of 400 gr. oskanik pіd hour of work with smd-components is guilty of becoming 260-270 gr. Z.

The optimal temperature for heating the tip of the soldering iron, as well as the need for tightness for an hour of manual soldering - indications, yak lie in the design features of the soldering iron, zavdannya, yak vin vykonuє. In robots with lead-free solders of a tubular shape, they can melt the melting point of 217-227 gr. The minimum indicator for heating the soldering iron tip is 300 gr. Z.

By stretching the soldering, it is necessary to uniquely overcome the overheating soldering iron tip, as well as the dry tip on the metal. Most often, work with solders, which do not include lead in the warehouse, and traditional tinols, most suitable for heating the soldering iron tip to a temperature of 315-370 gr. Z.

In some situations, when soldering smd-components, the results can be up to an hour of short-hour heating (trivality of the soldering iron tip is up to 0.5 seconds), as well as when heating the soldering iron tip to an indication of 340 to 420 gr. Z.

The order of soldering smd-components

The order of soldering smd-components:

1. Look at one of the contact maidanchiks on the back. For this, give a sufficient amount of tinol for a distant molding of the zholobnik.
2. Dalіd installation of the smd-component on the CP.
3. At the next stage, attach the smd-component to the additional tweezers, and immediately put the soldering iron tip on it, thereby ensuring the one-hour contact of the soldering iron tip with the sighting of the smd-component, as well as the KP.
4. Fasten the short-hour soldering with a pull of 0.5-1.5 seconds. If you sting prystosuvannya, then it can be brought out.
5. Give high-temperature soldering another reason: when the tip is attached, you will ensure one-hour contact of the tip with the output and KP.
6. Dali z protilezhno ї sting soldering iron side next file tinol pіd kutom 45 ° to KP, as well as the removal of the component.

Chotiri secrets - a pledge of successful soldering

Іsnuє chotiri the secrets of the yakіsny vikonannya soldering, further trivaloї exploitation of the details. Let's take a look at their report.

Main yakіsnі spoluki:

1. The correctness of stosuvannya solder and flux in the solder;
2. Cleanliness of the soldering iron tip, and heat the steps of yogo heating;
3. Clean surfaces that are soldered by metals during the first hour of the procedure;
4. Correctness of heating, sufficient heating of the working zone of parts.

As it became clear, depending on the temperature of the heating of parts, as well as the stage of heating the soldering iron, it is too late. Also, you should know the melting point of some tin-lead solders.

Solder melting point

The knowledge of technological warehouse soldering allows the solder to store the details for a long time, which is the best quality for the right professional. In this way, high-temperature soldering will show impressive performance.

It is very important for someone to know that it is necessary for otrimannya okіsnoї soldering during installation of radio components, so that the temperature of the tip of the soldering iron matches the working temperature of the solder. In different brands, solder won't blow. If you overheat the tip of the soldering iron, the solder will oxidize and the soldering will be insufficient. In addition, the tip of the soldering iron burns quickly at this point, and the solder ceases to burn on the new edge. As if the soldering may have a mirror glare after reaching it, and you can take it off only for the same temperature. So, for the widest brand of solder POS-61, the soldering temperature is 190 ... 260 ° C. The recommended temperature for soldering microcircuits is 235±5 °C, the trivality of the troch is more than 2 s.

When buying the simplest cheap soldering iron for a voltage of 220 V, as a rule, it is said that the wines overheat and solder badly. You can solve this problem with chotirma paths.

Method 1. Just as the soldering iron may have a sting near the shear, which is fixed on the body behind the additional screw (Fig. 1), then by adjusting the length of the shear in the heater, you can easily smoothly change the temperature. However, not all soldering irons are capable of such a design of fastening, and this method may be unacceptable.

Method is different. You can use LATR or a transformer with a large number of inputs. In this mode, the temperature is regulated by a change in the voltage that is applied to the heating winding.

Method 3rd. After heating the soldering iron, an additional resistor (rheostat) is switched on. With this, the tension of the resistor can be the same, like that of a soldering iron, and the nominal value of the support is selected for the selection of the required temperature. Such a dodatkovy resistor may be large in size and warm, which is not handy.

Method 4th. The electronic regulator, Fig. 2, allows you to smoothly change (by changing the resistor R2) the heating temperature in the boundaries. Attachment can be without transformer and small dimensions, which allows you to place it at the soldering iron stand. The circuit is not critical to the types of parts, and її adjusting the value of the resistor R4 (with a zero value of R2) to reduce the maximum voltage on the heating. The soldering iron, which is connected, can be attenuated from 15 to 300 W, and when replacing diodes VD1 ... VD4 with a larger stream - up to 1000 W.

It does not mean that the temperature of the soldering iron is universal and that soldering iron is suitable for absolutely all types. It is rich to lie in the form of solder, in view of the fact that the master works with the same materials, and also in the form of purposes, as in the case of wines.

And in general, the choice of optimal temperature is not so simple on the right. Ring the rozіvayut until that hour, until it is no longer possible to melt the solder. Ale in deyakih vipadkah needs more fine tuning.

There is one unbreakable rule: the temperature of the soldering iron is to blame for the melting temperature of the solder.

Moreover, the solder material can be melted even more before it fills the empty spaces and evenly spreads over the surface.

If the tip of the soldering iron appears to be overheated, the solder will oxidize and the soldering seam will not be removed. Before speech, oxides can appear on the soldering iron itself, and in order to get them, fahivtsy to please the activator of the sting - it’s actually more corisna river.

And if the tip of the soldering iron will not just overheat, but burn out, then the soldering material will stop burning on the new trim. “Cold” soldering (if the temperature of the soldering iron tip is less than optimal) will not give an accurate result.

Even if the solder material does not melt to a plain mill, the place of soldering becomes dull and short, and the joint is not necessary.

And one more important rule, more important for any soldering: the temperature of the elements themselves, which are soldered, is invariably due to the same.

Various solders

All the diversity of solders can be divided into two categories:

• refractory;
• fusible (soft).

A sharp heating and temperature rise are more likely than unique, and the frivolity of a soldering iron is not guilty of exceeding more than two seconds. Such objects, such as integrated microcircuits and field-operated transistors, are especially worthy.

To remove special powers to the warehouse of tin-lead solders, bismuth, cadmium, antimony and other metals can be introduced. Use low-melting solder in liquid rods, pastes, darts, powders, stitches, as well as tubes with a diameter of 1 to 5 mm with rosin in the middle.

Among the varieties of such solders, one can see brandy Felder and AIM.

And one more addendum: fakhіvtsі recommend not to pick up metal boxes, krishechki, plaques to save solders. Solders can stick to the metal - the result is rosin porridge on the walls, which will not be comfortable to work with.

Solid solders are characterized by the fact that they vibrate high-quality seams. In radio installation robots, the stench is richer, lower fusible. Moreover, you can see two subgroups of solid solders - copper-zinc and silver.

The first victors are used for steel, brass and other metals, which can have a high melting point. Tsіkavo, scho їhnіy color to fall in vіd vіdsotka instead of zinc. And the melting temperature, let's say, solder PMC-42 is 830 ℃.

Srіbnі pripoї mаut, mabut, even more mіtsnіst. Їх zastosovuyt, mainly for soldering copper-brass and silver-plated brass. The melting temperature of such solders is in the range of 720 to 830 ℃. Under an hour of work with such materials, put on a palnik.

Melting of various materials

At the master, you can blame the need for soldering midi - mov, for example, you can go about the trumpets of scorching or otherwise, from colorful metal.

It is possible to use a soldering iron with a middyu and її different alloys, zastosovuychi different solders like soft, so hard. In this case, the temperature of soldering the middle elements with soft solders should be 250-300 ℃, and with hard solders - 700-900 ℃.

And what can be the temperature of the soldering iron tip, as if you need to solder, let's say, polypropylene products? In this case, the optimum temperature will be +260 ℃, and the reasonable allowable range is from +255 to +280 ℃.

If it is higher than 271 ℃ and if you change the hour of heating the tool, then the surface of the soldering zone will warm up much more in the interior. Tse means that as a result of the brewing, the spitting will appear even thinner.

Korisn_ pristroї for vimіryuvannya

Practice shows that the temperature of the tip of a vicorous soldering iron is correct, then, chill, soldering matima, a characteristic mirror glare.

First of all, the porosity and dullness of the zone soldering are evidence of those that the procedure was carried out not very well.

Finding the optimal melting point can be done by way. For which you need special soldering iron heating regulators (laboratory transformers). Є, vtim, і the simplest way to adjust the temperature is to change the temperature of the sting.

But this method, perhaps, is only relevant for self-made fittings for soldering. In whatever mood, the master can be recognized in advance, at a certain temperature, or at a certain temperature, the solder stings a mirror glare.

Having mastered this knowledge, you can find out the right help for the job.

For the obvious financial possibilities of the varto, a special thermometer (sensor) for the soldering iron is needed, which will freeze and calibrate the working temperature of the tool.

Such sensors at once can be done in abundance. I be-yakoy bazhayuchomu pridbati will need a model online or offline in a difficult warehouse. The stinks of robbing the swidky and accurate temperature gauge of the soldering iron tip for the help of a thermocouple (thermoelectric convertor).

When choosing such a thermometer, you should pay attention to such characteristics, such as zdatnіst, range of vimіryuvannya (for example, vіn can be from 0 to 700 ℃), accuracy, dimensions, possible life.

However, simply controlling the temperature is not enough. It is important that the soldering iron saves a constant, with possible haircuts, the voltage in the thread - that is the necessary special stabilizer.

Such an attachment can be prepared independently - with free access, simple schemes. In addition, at the same time soldering irons and soldering stations are already being used with a stabilizer.

And also a lot of professional soldering stations allow you to accurately set the temperature and the required soldering mode, let's just press the buttons or the toggle switch. It is important to simplify the process of work and allow you to be sure of a good result.
