Desoldering is the removal of solder and components from a PCB for troubleshooting, for repair purposes, and to salvage components. The tools for desoldering are solder wick, heat guns, desoldering pump, removal alloys, removal fluxes, vacuum and pressure pumps with specialized heater tips and nozzles, Rework stations (used to repair printed circuit boards that fail [...]

The Basic Soldering Guide

admin — Tue, 16 Oct 2007 05:10:00 +0000

Soldering is an electronics process join together two or more metal by melting and flowing a filler metal (having a relatively low melting point) into the joint. In other words, you use a metal that has a low melting point to adhere the surfaces to be soldered together. The filler metal used in the process [...]
