From info I have been told from design standpoint, via in pads helps with managing EMC issues with working design, in particular for high speed digital/dense populated type PCB's. We had a manufacturing customer that had very low yield because of th

From a manufacturing standpoint, this isn't very nice. Vias will tend to wick solder away from the pad, resulting in insuficient solder joints, which require touch-up. The amount of times any solder joint is reheated should be minimized, as extra h

There a several things you can do to prevent the solder wicking down the hole with the current design, and that's where you should focus. Cost goes up as you go down the list, but in neither case do you need to respin the board, have solder starvatio

It seems like most people want to X-Ray their BGAs. We're going to start doing a lot more of them and need to consider X-ray, too. Q: Do most people/companies X-ray everyBGA or do they just do SPC? Q: Can you get away with spending 25K? 30K? How muc
