I meant to include this in the original message. One, the solder balls are on the circuit side of PCB. Two, some of the vias on both top and bottom are closed and some are not. Is this a process problem with the board house(s)?

I encounter the problem, it is easy for pad(copper) to drop off from the PCB, which is Ni/Au finish. so my question is whether there is any specification about the force between pad and laminate material, and does the PCB corpoartion test this parame

Do you have any picture or reference how can we determine black pad or plating contamination. I have heard about a lot of problems regarding BGA's and normally these components are only replaced or heat it and that's it ,after that the boards are wor

We are getting broken traces in PCBAs, any idea why. In addition, only few of the boards show this problem, hence I don't think it is an issue with the board manufacturer. thanks, SS
