Hi,
I want to ask whether there are better methods to remove solders covering through hole pads rather than using a solder pump.
It is inconvenient when the circuit is complex and components are closed so that there is too less space to use sodler pump. I have tried using desoldering wire but the result is also not good.
Thanks!
Try solder wick.
I think de-soldering wick (e.g. Soldamop) is 100 times better than a solder sucker. It works like magic, ia ao much gentler and leaves the area completely clean.
a desoldering station with a real vacumme pump and small probes work well to clean off the mass. you can also use fine conductor to feed in behind the legs of IC's and then simply pull the wire out under the legs as you heat the legs this is after you have used a desolderer to remove the bulk, this works well for smt. for through hole, i have found cutting the legs off the body, remove the chip, use a flat bar soldering tip, hold it agaist the base of the legs to soften the solder and also holds down the foil on the board as you are pulling out 4..5 legs at a time. this you do top side. since the chip is being removed for most obvious reasons there should be no problem in snipping the legs off the body first. a hot hair pen also works well, it blows the solder away..
