Profiles are absolutely the first course of action to validate. A few additional questions would be: * Moisture can cause warping as well, verify the manufacturers recommended handling procedures were followed. * Where is the suspect BGA located

BGA crack and strain gauge measurement

There is no standard for a strain gage measurement of allowable deflection of a board or a fixture. It's possible that your fixture is causing the BGA cracking that you see. What protion of the BGA is cracking? If it is the solder connection, sear

Seriously, OSP?, change the board finish, you are the OEM, correct? You have the power! Also, as another poster mentioned, high force applied at ICT ( possibily to cut through the OSP goop ?!? ) could be warping the board enough to crack the joints.

Is this a PBGA? If yes. run a flat steel rule or edge across the top of the PBGA. Is it flat or cupped? Is this a TBGA (super bga). I have seen issues with a suppliers heat spreader design that actually will deflect the corners down and raise the

Hi, The issue is very complex and difficult to arbitrarily divide the types of components. From research we perform today together with our customers to design a work-at-SMT accurate as much as possible, I can summarize that vast time differences de
