Soldering

Soldering is the process of joining metal surfaces together using a filler metal to create the connection, and we call this filler metal Solder. We use soldering to create connections between a lot of things, but most commonly to create connections in electronic circuits. Nearly every electronic device you own has what’s called a printed circuit board, or PCB, in it, and each of these circuit boards has tens, hundreds, or even thousands of soldered connections depending on the complexity of the device.
