Cut a small notch in the tip such that it will fit squarely over the pin to be desoldered while the soldering iron is still in contact with the pin, solder and pad. Leave the iron on the solder joint while "popping" the solder sucker. Another trick that seems to help, especially with pins that have connections to internal copper planes, is to "float" them with a little fresh solder and flux before trying to use the solder sucker. You have to work fast and don't let the joint cool down. It is definitely possible to damage a part this way due to overheating so practice on old boards first. Working under a deadline is no time to learn new techniques, I'm sure you would agree. :-( Rob -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
