We process a double-side reflow board (10 ups). Chips and IC's on the bottom side while chips, IC's plus thru-hole connectors and IC sockets on top side (bottom side first then top side reflow). In the past, we were not encountering any soldering pro

We are continuing to struggle with voids under BGA's. Our problem are not consistent. some CCA's are perfect but others have pin hole sized voids. Does anyone have any feedback on Indium 92j and how it performs for bga's?

Defects will result, Your cooling rate is affected because the hot air is not circulated properly. Outgassing will appear and you'll have pin holes / blow holes, disturbed joint etc. Correct me guys if i'm wrong. Thanks

The solder on the rest of the board looks good. There are no large components around these parts. We check the profile using a KIC and it met the recommendations of the solder paste manufacturer. I have not did a dip test of the board or components.

I just had a "how could I have forgotten" moment. By any chance are these double sided boards and the cracked components are on the fist side? If so support pin placement could be the problem. In case more info would be good.
