How to desoldering parts

If you are out of order any equipment, you do not rush to throw it. After all, if you are fond of creating electronic DIY, then get into his stock more than a few details will never be. In this article I will discuss how to vypayat details. So, let's begin.

What do you need from tools

Of course, as you and I well, can not do without a soldering iron, well, except it you will also need:

1. Tweezers or crocodilians. In the process of heating the solder will inevitably warm and very detail so not to burn your fingers, it is better to use a pair of tweezers. And fixing the crocodile you still create additional heat from the components.

2. Hollow needles, specially designed for disassembly. They are not expensive, so buy them is not a problem.

3. Special Remover braid. She plays the role of a sponge which absorbs molten tin, freeing the connection terminal.

4. Desoldering. Well here everything is clear and understandable. In fact, a very useful thing, if you engage in regular watering details.

Yet it is important to prepare your desktop. Having a good and high-quality lighting is strictly necessary. After all, our task is "to get" free parts, not to put vision.

techniques for dismantling

Removing parts only with a soldering iron and tweezers

So let's start with the easiest option when you need to unsolder, for example, a capacitor. To do this we need you to take the heated soldering iron and heat the two terminals, and then quickly (but it is the most carefully) with tweezers or by hand to pull out of the board capacitor.

The same principle can be vypayat transistor from the board.

And here at the diodes, non-polar capacitors and especially resistors often folded when mounting legs with the reverse side, which creates additional problems when removing the parts without special tools.

In this case, you can do so: heat sealed one of the contacts and with an effort to pull one end, and then repeat the procedure with the second.

So, to simplify your work will use special tools.

We use special. tool

If you have a set of needles, the process of watering is as follows:

To start warm up contact and a soldering iron put on to output the required diameter needle (important that the needle held in hole in the circuit board), then continuously cranking around its axis the needle handle and forward until the tin to cool and take out needle.

Note. No special set of needles, it does not matter. Take an ordinary medical syringe with a thick needle possible. Then carefully grind off the edge and you have done your special device.

We should get a clean bare conclusion, which is very easy to remove.

The whole process lasts as long as all the details of the legs will not be released.

Remover braid

Produce desoldering braid with dismantling is very simple. Before you begin heating the place of contact soldering, apply at the end of the braid alcohol - rosin flux, then attach the braid to the contact details of desoldering and soldering iron to warm up. As a result, the tin should soak into the sheath and contacts will be released.

Desoldering

Desoldering used as follows: cocked spring, the contact place is warmed, then Desoldering tip is brought to reheat the solder is pressed and a spring. Due to the generated vacuum solder is drawn into the device, thereby exempted contact details, and it can be easily removed from the board.

conclusion

That's all I wanted to tell you about right, and most importantly safe to remove the parts from the chips. If the article was useful to you any interest, the vote Like. Thank you for your attention!
