The ability to solder can be useful in a variety of situations, from the repair of electronic equipment to the need to solder a leaked car radiator. Knowing the correct technology allows soldering with a high degree of reliability.
It is necessary
- - soldering iron;
- - solder;
- - flux.
Instructions
Step 1
In the overwhelming majority of cases, soldering is associated with the repair or assembly of electronic devices. In order not to damage electronic components, select the correct power of the soldering iron, it should be between 25 and 60 watts. The smaller and more sensitive to overheating the elements, the weaker the soldering iron should be. For example, the weakest device should be used to solder microcircuits. For soldering the leads of transformers and other massive elements, a more powerful one is suitable.
Step 2
To get high-quality soldering, observe the following rules. First of all, prepare the place for soldering and the leads of the elements, they must be cleaned and tinned - that is, covered with a thin layer of solder. For soldering, you need a flux, use rosin or its alcohol solution. In the latter case, it is convenient to use a bottle with a nail polish brush.
Step 3
Prepare the soldering tip before soldering. Its tip should be covered with an even layer of solder. If the sting is black, burnt out, carefully clean it with a file, then dip it in rosin and tin it right there. Soldering with an unprepared soldering iron is difficult, it does not hold solder.
Step 4
Make sure that the soldering is not "cold", that is, performed with a poorly heated soldering iron. With such soldering, the solder is not liquid, but lumpy, the junction is not poured with it, but smeared over. The color of the joint soldered in this way is dull, gray. Such soldering is very unreliable and does not provide the desired contact.
Step 5
If you solder a radio component into the board, then with the right technology, the solder should completely encircle the leg of the part and capture the entire contact area around it. The color of the solidified solder in this case is silvery, bright. This soldering is very reliable.
Step 6
When assembling an electronic device yourself, get used to doing everything very neatly and beautifully. Beauty is the key to the reliable performance of the product. If the device is sloppy, the installation is very careless, the wires are laid completely randomly, one should not expect good work from such a product. By saving time on installation, you will later spend much more on finding the reasons for the inoperability of the assembled device. Conversely, if everything is done neatly and beautifully, the device usually starts working without any adjustment.
Step 7
Sometimes it becomes necessary to solder metal or steel parts. Rosin will not work in this case; you must use special store-bought fluxes for soldering metal elements. Alternatively, you can use a regular aspirin tablet. Work in a well-ventilated area as the smoke from aspirin is highly corrosive (do not inhale it). Remember that electronic components cannot be soldered with aspirin.
Step 8
You can also use hydrochloric acid with a piece of zinc thrown into it as a flux for soldering iron. You can use zinc from an old battery case. A small bottle with a volume of about 50 ml will require a third of the battery case - just cut the zinc plate with scissors, put the scraps in the bottle and leave for about a day. Apply flux to the place of soldering with a brush.
