 When the desoldering pump and solder wick just aren't cutting it, you might be tempted to try heating all the component pins at once and just giving the part a good yank. Yeah, it might work, but you might also damage the board if the solder cools too quickly. What we need is some slow style solder that stays fluid longer. ChipQuick's desoldering alloy does exactly that. It's marketed for use on service mount components, but it works fine for through-hole parts too. Apply flux to the component leads to clean and prep the surface. Then melt a little bit of alloy on each pin. It doesn't take much to work. Once heated, the solder will stay molten for several seconds. Plenty of time to pull the part out. Clean up with solder wick and some flux remover or alcohol. And the dishes are done.
