Often handyman falls repair LED lighting or other devices in the SMD components and chips. It has long been a thing of the past, when the board repaired exclusively hams. That is why the issue is now urgent purchase of such a device, like a soldering iron to chip. But many do not know how it differs from the usual and familiar to all such devices. Today we try to understand this, incidentally examined its characteristics and advantages over the usual soldering iron.

What is the soldering iron to chip and why it is indispensable for the repair of modern devices
To begin with, that all SMD components, which include chips, did not suffer from overheating. It is possible that they will be immediately after the repair work, which is highly unlikely, but it will last very long. It is for this reason it is necessary to use a special soldering to chips, which the heating temperature is regulated. Let us examine this in more detail.
Generally soldering irons can be divided into 4 types:
- Gas - such devices are intended primarily for solder connections in junction boxes. Their main disadvantage is the complexity of the work, but by beginners with no experience is better to abandon such a soldering iron;
- Electrosolderers spiral type - such devices are the most common. Among the shortcomings can be noted a fairly long heating. At the same time it should be noted that it is the best for home use. Quite durable. For proper operation of the service life can reach 10 years or more;
- ceramic type - differs from the preceding heating element. Among the shortcomings - relatively fragile. It may be damaged at the slightest mechanical stress. But he warmed up almost instantly;
- Soldering pulse type. Such devices, together with thermostat called soldering stations. Among the shortcomings can be noted only a high cost. And yet it is justified functionality. Such a soldering iron heats up very quickly and is ideal for today's chips.
Thus, we can conclude that today's talk will be devoted to pulsed devices. Yet for ordinary spiral or ceramic irons in it too, there is, but more on that later. To begin to understand in detail the advantages and disadvantages of each type.
Which to choose a soldering iron or the application of different types of devices
Let's start with the fact that the gas soldering irons although demanded by professional electricians, but gradually losing its popularity. The fact is that before the installation of junction boxes in apartments or private housesPractically the only one compound was twisted wires. And taking into account that the contacts should be strong and tight, to avoid heating them had propaivat. It was during this work gas appliances are indispensable due to their mobility. Now there are more simple variations of the compounds, such as terminals the WAGO-type, and therefore gas soldering iron is slowly but surely leaving the world of electrical engineering.
As for soldering spiral and ceramic type, they are also forced out from the shelves, but they are better suited for gas at home. After all, there is always the device, which is necessary to repair the wire or solder torn down. Here, the terminals are not in use. Indeed, in this case, the connection is rather cumbersome. The problem is that vypayat small parts of a printed circuit board or chip them fail. Rather, there is a danger of failure.
But soldering gun or the station - this is the most high-tech devices. With their help it is possible to work with the smallest details, even though they are just as functional and soldering wires. So, if you face a choice problem, in spite of their high cost, advantages of soldering gun in the face.
As vypayat chip soldering of the board without damaging it
Such work requires extreme care and accuracy. If we are talking about soldering station, Everything is a little bit easier. But now it is to understand how to perform such work using a conventional soldering iron, using the means at hand. This is why we will provide step by step instructions and the sequence of actions, explaining everything in the photo examples.
| photo example | action taken |
 | For example, consider a computer board RAM from which to unsolder chip, as indicated by arrow. You will need a regular soldering iron and fine steel wire |
 | Under the legs need to shove this same wire to its full length. This requires accuracy, but the haste in such actions completely out of place |
 | Further it is necessary to fix the end of the wire at any place on the board. For the reason that our board has defective and is shown only as an example, to fix the wire directly to the connection terminals. It is understood that if you only need to replace the chip, then at this point you should consider where to fix broach. While nothing prevents and clean the terminal at the end of work |
  | Now pulling wire to gently heat the contacts one by one. Here, a strong stretch is not needed, otherwise the wire may break off. Under such circumstances, you just need to replace it, and then continue the same actions |
 | Here is the fee after broaching has passed through all the legs |
 | Now you need to check whether the solder from the bottom left. To do this, repeat the whole procedure again and extend a wire |
 | If she is caught somewhere, you need to warm up the place a soldering iron and pull it |
 | Accurately having hooked a screw-driver chip can be sure that the hot-melt adhesive as well behind the printed circuit board |
 | Repeat the entire procedure for the second row of legs |
 | After the chip was removed, remove excess solder soldering tip |
 | Here is the place to solder a new chip |
Important information! In any case should not be allowed as the overheating of the PCB and chip if you plan to use it in the future. This can result in wasted time and the failure of the microprocessor.
But not only the soldering iron can be carried out similar work. There is such a device as a hair dryer for soldering. That is about it right now and will be discussed.
Where to buy a hairdryer for soldering chips and what it represents
Buy such equipment in our time there is no difficulty. Of course, the price of dryers for soldering high enough. In addition, if a person is not familiar with this type of equipment, you work with him, he can not - there need special skills. Although professionals argue that to learn it is not too difficult, but in this dryer is quite convenient.
In fact, the principle of its operation is similar to the functions of the building dryer. Differences constitute only special thin nozzle on the nozzle and the temperature which can reach 8000FROM. However, too much detail in this equipment, we will not stop. It is only necessary to mention that if you want to have the ability of manufacturing such a brazing hair dryer and their own hands. However, this is a topic for another article, which is sure to appear on our site (if it is someone of interest, please write in the comments). And now look at the main differences from the conventional soldering gun.
The main difference is, of course, the operating principle. The fact that heating soldering gun carried out by means of the transformer secondary winding. Simply put - it Vyzhigatel, familiar to all from childhood. Of course other power used here, but the principle of operation is similar. Well, if you pay attention to the high cost of such devices (meaning high-quality devices) or the poor quality of the ubiquitous Chinese producers (where are we without them?), it becomes clear that the best option will be to make such a soldering gun with his own hands. For those who are interested, we will discuss these homemade products in the following articles. And now it makes sense to pay attention to the cost of soldering soldering chips on Russian shelves.
| electrical appliance | Make and model | Power consumption | Average, rubles. |
| soldering gun |  | 100 | 750 |
| soldering gun |  | 100 | 1580 |
| Soldering Station |  | 80 | 3500 |
| Soldering Station |  | 80 | 49000 |
As can be understood, trading range is fairly wide. But today is small enough reviews on this or other equipment and means to make a full picture of the price-quality ratio is unlikely to succeed. But even if the chip is small enough and the work of conventional soldering iron seems impossible, there is a way to remove it without having to buy expensive equipment.
An important tip! If thick sting conventional soldering wound copper wire cross-section of 4 mm (spiral along the entire length), leaving a piece of stick out a length of 3-4 cm, it is possible to get such a device to any part. In addition, the temperature of the new sting will be much lower, thus reducing the risk of overheating the circuit board components.
So before you buy an electric soldering iron to chip, you should consider whether it is really needed. Of course, if a person is often engaged in similar work, this device needs. But provided rare or one-time use, it is possible to dispense with improvised means, modernizing a conventional device.
As for such devices for home use, then the choice depends on qualifications. The fact that the soldering irons are made of different capacities, from which depends on the rate of warming and temperature elevation. Power range between 30 to 100 watts. It was from this setting and must depend on what soldering choose to home. If you experience a little, it will be the most appropriate low-power devices of 40-50 watts. As for soldering at 100 watts, they are hardly suitable for home use.
Important! Choosing a soldering iron is necessary to pay attention to the fact that for each power use your solder. If devices with high power needs refractory material, the weak contrast, softer.

Summarizing
In conclusion, it is crucial to remember that the need for soldering chips, if you can not buy expensive equipment:
- Solder, or rosin acid;
- Thin steel wire;
- Irons with as less power;
- A piece of copper wire cross section of 3-4 mm.
That's all. Agree to buy soldering station for single use there is no point if you can do with improvised means. Much more convenient to buy a soldering iron for soldering of low power cables. In this case, it is always handy handyman at home.
At present, that's all. We hope that the information in the article will be useful to someone. And if you still have questions on the subject, then ask them in the discussion. So should we be interested to know what methods you use when soldering chips. And to the reader it easier to understand the essence of soldering with a hair dryer, offer to view a short video:
