I have a BGA with ground plane under it. The problem I have is that the ball pitch is too small to create a single ground (power)plane under it with all the via pads unsuppressed. See picture attached. Instead of having one GND plane I have small islands. Is there any way to suppress pads on vias that don't have connections on that plane so that I have more room to create a single GND plane?
Thank you. -- Gennadiy Kiryukhin Development Engineer ATSI 8157 US Route 50 Athens, OH 45701 Phone: (740) 592-2874 Fax (740) 594-2875
