Anything about soldering technology, techniques and tools.

Please, do not use this tag for questions about welding, which is another process and uses quite different techniques and tools.

Soldering is a process where two metallic parts are joined together using a third molten metal or alloy, called solder. The molten solder first wets the parts to be joined and then, when it cools down and solidifies, keeps them into place. Soldering is often used to fasten electronic components on a PCB.
