Solder Reference Materials Collection

Soldering is a central and critical group of techniques in electronics, copper-based plumbing, and the engineering of delicate parts. It involves joining two or more metal components together by melting a lower-melting-point filler metal, the solder, and allowing it to flow into the joint. This creates a strong and (where relevant) electrically conductive bond when it cools and solidifies. This process is key to connecting electrical components onto printed circuit boards (PCBs) and assembling intricate mechanical and jewelry parts.
