We are experiencing many solder balls after wavesolder. Two different board suppliers of the same board are involved. My initial reaction was that it was the process but in researching information in this forum I am beginning to wonder. How can on

The reason why we are using soldered PCB jumpers is that it is cheaper than dip-switches, 0 ohms resistors, etc. Field updating is also easier. We are producing different variants of some of our products. It would nice if we could presolder the PCB

Just thought of something. Sorry to be late with this. If you decide to dewarp these boards, consider: * Marking the boards perminantly with a code to help key your failure analysis people that a customer return was processed differently than other

Would someone be able to direct me to information on residual BGA stress please? I've been told that mounting the BGA involves residual stress to the solder balls due to different expansion characteristics of the BGA versus the board at the moment of
