We've just completed an experiment for one of our customers using lead-free HASL. From a manufacturing standpoint, everything seemed to have run fine. Solder profiling seemed to be unaffected, pick and place was unaffected, and the end result looke

We have recently faced lifted lead problem that happened on our 20 mil pitch QFP. We have infact pushed it back to the incoming quality, but still I have a few questions to bring up : 1) what is the typical coplanarity tolerance that ICs' manufactur
