No, there is no such information. Choices are: * Recognize that any voiding is a process indicator and that when observed, indicate a requirement for taking corrective steps. * Tell your quality people to quit looking at components other than BGA wi

Kris, I assume with voids you mean acceptable solder coverage of pad and lead. As Dave mentioned I also have not seen any specific studies on voids, but workman ship standards exist about acceptable coverage of pad and lead (both consumer and MIL)

Chrys and C.K. (or Little K from what I'm told), Where "I" work at, our fine management staff has informed us of "Smart Solder"! Not sure who makes it, but they claim it will make all your soldering problems go away. I'll send ya more info on it
