How to learn to solder

How to learn to solder

The ability to solder only vitally needed todayradio amateurs and masters, repairs appliances. However, the ability to handle a soldering iron will prevent virtually any representative of the stronger sex, because a variety of situations can occur in life.

In addition, learn how to solder is quite simple, and a lot of the time it does not take.

Fundamentals and terms

The first thing to get to know somespecial terms. Brazing itself - is the physical connection process of the two parts using a low-melting alloy. This alloy or "solder" generally has a lower melting point than the objects it connects. In most cases, used lead-tin solders melt at a temperature of about 220 ° C.
Before you apply the solder to the matingmaterials, they need to be cleaned from the various oxides. This is done by means of a flux - organic or synthetic substances, which when heated produces not only the removal of oxides from metal surfaces, but also allows the solder to flow better and fit snugly to the solder materials. The most common flux used for many years - based on rosin, but recently there was a set of more effective liquid fluxes that are not aggressively act on the soldering iron.
Soldering irons, too, are very different, however, forFirst, you fit an ordinary electric soldering iron low power. If resources permit, you can buy a soldering station: set includes a soldering iron itself, the various stands, and most importantly, power regulator, which will allow you to avoid overheating of the soldering iron. The sting of the new soldering iron must be carefully "obludit", that is, apply a protective layer of solder.

soldering Technology

Actually soldering process is quite simple. The first step is to heat the soldering iron. The heating temperature is considered to be sufficient if the solder melts the solder. Take care not to overheat the sting. On superheated soldering iron solder does not stick, and runs down drops. Then you need to clean up the place of the future adhesions with a file or sandpaper. Then, on the bare surface of the need to apply a thin layer of flux and obludit them. You can either just dip soldered parts in the molten solder, or touch them tin-plated soldering tip. In any case, the result should be a continuous layer of solder.
It only remains to connect the parts and wellfix them in position. If you wire solder, the reliability can also twist them together, although in practice it is usually not necessary. Securing tin-plated details, start their heating soldering iron. You need to ensure that the details of the temperature exceeds the melting point of the solder. In some cases, you may need an additional amount of solder is applied to the soldering. Ensure that all the solder melted and securely joined parts along their entire contact surface, because otherwise the contact will be unstable. Wait for the complete cooling of parts before releasing them, as any movement during the solidification of the solder may break the bond strength.
To get started is to practice on unnecessarycut wire, old printed circuit boards and contacts to learn how to calculate the temperature, the required amount of flux and solder. A few hours of practice is most often enough to get the skill with a soldering iron.
