How to solder with a soldering iron?

Every person at home has a large number of different electronic devices, which after a breakdown can be repaired on their own, without resorting to the services of third parties. It can be a garland, and a children's typewriter on the remote control, and a clock, and much, much more. Most often, the breakdown is easily eliminated by replacing an element or eliminating a chain break. In this case, the problem is easily solved, the main thing is to know how to solder with a soldering iron. And as a result of simple work it is possible to restore the working capacity of the product.

If you are puzzled by the question "how to learn how to solder with a soldering iron," then, first of all, you need to know what you need.

1. Soldering iron. This is self-evident.
2. Rosin. It is also called flux for soldering and is necessary for the tinning of parts and wires. Without it, it is almost impossible to get by, since it is impossible to solder properly without it: the soldering metal simply does not "stick" to the surface to be soldered.
3. Solder. This means metal, which is used for soldering. Most often this is tin, since its melting point is lower than that of other metals. It is often possible to meet solder, which already has rosin in it, so the problem, how to solder with a soldering iron, is much simpler.
4. Stand. It is necessary in order to secure the surface of the table on which the soldering will take place, from spoilage due to ingress of solder, rosin or from contact with a red-hot soldering iron.
5. Wet sponge. When working with a soldering iron, its sting should be clean before each new soldering process. A sponge is necessary to remove dirt, residues of rosin or solder from the tip.

If all the necessary tools and components are available, the working area is prepared, then you can begin to study the technique, how to solder with a soldering iron. First, you need to prepare the elements that you want to connect, be it wires or pins on the board. The wires must be cleaned of insulation, after which all the wires are tightly twisted. If a repair is performed in which the soldering process is carried out over the electronic board, then the necessary contacts should be cleaned of the old solder. This can be done with a soldering iron. To do this, it needs to be warmed up and carefully remove the old solder with a sting.

The next step is tinning. For this purpose, the tip of the heated soldering iron is lowered into the appropriate jar, after which a small amount of rosin settles on it. This solution should be well lubricated stripped wires or contacts.

After rosin is applied, it is necessary to conduct the soldering process itself. The soldering iron takes a small amount of solder, which melts under the influence of high temperature and becomes jelly-like. It should be applied to the place of connection of wires or wire and board contact. Then solder should be allowed to cool and harden for a few seconds. It remains only to check the quality of the connection for strength. That's all, now you know how to solder soldering iron.
