I have lots of experience with thermosonic gold ball bonding. You can read the literature and you will probably find some papers that say you can do it. I have never been able to do it. We gold ball bond all day long with little problems at all bu

Hello Chris, To be honest, it's hard to believe you could not bond to ENIG at all. Yes, the gold layer is thin and hard, but it just narrows the process window and does not make the bonding impossible. I say this, because we have been using TS gold w

I've faced this several times in the past, and the only real solution is to wirebond before SMT assembly. Everything leaves a residue, and trying to clean a residue off later is basically hopeless. This may require some trickery in your SMT process

Thanks Mr.Dave. Sorry for the delay. One of our major prolems in ENIG plated surface is that wire does not stick. For many years we were getting a bond strength of 14 grams in both ENIG and electroplated surfaces. Now one vendor supplies ENIG boards

Do you bond with Al or gold wire? What happens if the Ni is over 150 microinches? Thickness of nickel is one those things that we have not been consistent with. The industry seems to pretty much universally call for 100-200 microinches. Our old board
