<I've tried using a heat gun to unsolder things, and I can't get it to = <work. Either the solder doesn't melt, or the board gets too hot an bad = I use that trick to get parts off board where I don't care about the board. Sometimes I apply a propane torch. I get good parts but the boards a mess. If I want to lift parts and keep the board I have a tin container filled with about a 1/2 inch of solder (used for wave soldering). heated over a gas stove (coleman) I can float a board and pick off components with tweezers. takes a little care to keep the heat reasonable.
