Subject: [TN] solder joint failures
So we’ve got a new toy, and now can image SJ failures a little differently. Requesting all experts to help me speak more intelligently about what we see. (until AJ-820 is published ☺)
These are of major interest to me today. It’s the easy stuff. It’s the weak link. It’s thru hole. As always, I may or may not know the history. As an independent lab, our customers don’t usually tell us much. I suppose they’re fearful that we may just regurgitate.
