In place of solder wire, you can use low temperature solder paste to speed up the desoldering process even more.
There are low temperate solder wires available like ChipQuik that you can use specifically use to help remove components. Sometimes it's hard to heat them all up fast enough but adding flux and a good amount of fresh solder to connect the leads will speed things up. It will really help when trying to desolder components with three or more leads. Adding fresh solder to the joints is really your friend here. If all you have is a soldering iron and some solder, you can still remove parts, it's just much harder than all the other methods I've shown. Be sure to wear eye protection because you do not want molten solder in your eye.Īll of the desoldering techniques shown in this instructable should be done in a well ventilated room as well as with a respirator if you are going to use a flame to desolder components. The parts usually will drop in and if not, try adding extra solder. If you're salvaging parts, don't be afraid to use tools to cut the board like a hacksaw or large snips.Īnother brute force method is to heat the leads of the part up and smack the board down against an edge of a container. Even better if you have a bunsen burner with a mesh screen tripod. After that just use tweezers hold the board over the solder pot and use pliers to remove all the parts you want.Ī good alternative to this method is using a small butane or propane torch to heat the bottom of the board up while pulling components off with pliers. You can coat the bottom of the PCB with flux to speed things up a bit, but it isn't necessary. I find it very therapeutic and relaxing to remove all the components off of a board. I have a drawer that I keep scrap PCBs and every once and a while, I'll salvage all the parts from them. I use this method to salvage a lot of components at once. This first technique is the most destructive and should only be used when you do not plan on keeping the board.
