Solder is the glue of electronic circuits. In addition to a permanent mechanical connection, solder provides an electrical connection. Not too much unlike glue solder combines two separate metal pieces with a bonding material. In this case, the bonding material is a metal or allow with a relatively low melting point.

When soldering together a circuit, the quality of the solder joint is crucial. Most people probably recognize the need for a high-quality soldering iron, like the FX-888D from Hakko, but about the other tools?

Building a modular soldering station is just as critical to making good solder joints as the actual solder itself.
