I won't even guess, but I would suggest that if you don't get much help here (pretty tough question), you might try dogging somebody at IPC. They seem to have a pretty good handle on that kind of stuff. All I know for sure is that we shipped a worki

(Its a flex head) I have made a trial program to determine at what point it stops. This is how it goes: I load the program, push the start button it will zero and pick components with head 1. As soon as it finishes placing head 1 parts it halts wher

CL pretty much hit the nail on the head. But also remember that solder paste will not go "bad" if not kept cool. It is not a fruit or perishable item (sorry guys, it's not). It's just metal and flux. The only reason they want you to keep it cool

Well, I do know that different solder pastes have different lives. Sh@t, some solder pastes change characteristics from lot to lot. That's why we always restest solder pastes from different lots when doing an evaluation. Some of it has to do with

Well I am a CM, it has to be that OSP finsh!!! hahahaha seriously I hate that finish. but this is big BGA and there could be a multitude of issues as you suggested. Do not assume that the boards were 100% tested for all vias and lines unless yuou
