Acetone is likely not compatible with several component types, the evaporation charactoristics are desirable. IPA is more compatible, though, may not solubilize the residues. Austin American Technology developed MegaSolv JB and MegaSolv NOC for the

We use itty bitty drill bits in these cases. You can get one from your PCB supplier. Be careful they break easy. Russ

I'm trying to solder a 0.011" lead into a 0.015" +/-0.003" hole. Stop laughing please. This is normally possible with difficulty, except if the lead is removed and the attempt is made to re-install a lead. Anyone have thoughts on how to remove nea
