Soldering is a technique for joining two pieces of metal together by melting and flowing a filler metal into the area where the pieces are to be joined. The filler metal, or solder, is an alloy that melts at a lower temperature than the pieces being joined. Soldering is commonly used in electronics, plumbing, certain types of metalwork, and jewelry. This module will focus primarily on soldering as applied to electronics, including the composition of different solders, the role of flux, joint preparation and proper soldering technique.
