BGA Pad Lifting
After reworking BGA components that use thermal grease we sometimes notice pad lifting. Can the BGA pads be repaired? Any suggestions?
|Expert Panel Responses|
When you say pad, are you talking about the pad on the board? If so, the board would need to go to a board repair facility. If you are talking about the ball on the BGA itself, there are several kits available that would allow you to re-ball the component.

My Opinion: I suggest on preventing the Pad lift not the repair
Bosch Automotive Electronics India Ltd.
Pad damage at BGA sites can be repaired reliably following the IPC 7711/7721 Repair guide, procedure 4.7.3 Surface Mount, BGA Pad Repair, Film Adhesive Method. This is a very common occurrence and with a skilled Operator the repair process can be performed to very high level.
