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

Have you done any analysis on the failed rework? There could be any one of several reasons, i.e. bad alignment, wrong reflow profile, bad pad plating, etc. More information will help us help you.

Sounds like you have some delamination problems. How hot is the board getting? Try baking the board prior to rework. Is the quality of the board good? Goog Luck. MrMaint

Good Morning Vijay, It sounds like the PCB is getting too hot at rework. Is there any way to attach a thermocouple to check actual temps? This would give you an idea if it is your process or your PCB. Good Luck Chris

Any concerns on the IR in melting connectors etc. simply cover the part with aluminum foil. That will prevent any heat from attacking the component. The Ersa unit is in my mind the best bang for the buck.
