solder - Computer Definition
Pronounced "sod-er." A metal alloy used to bond other metals together. Tin and lead are used in "soft" solders, which melt rather easily. The more tin, the harder the solder, and the higher the temperature required. Copper and zinc are used in "hard" soldering, or brazing, which requires considerably more heat to melt. See braze, reflow and wave soldering.
