I know the paste mask layer is also called the stencil layer. It’s only used for assembly. I want to know if the paste mask layer (both top and bottom layer) is necessary for through hole components. For SMD components I know the paste mask layer is required to solder the components. Is it necessary for through hole components?
After We have assembled the Virtex-4 FPGA BGA package on our custom design PCB, we check for short circuits between all power grounding and they shows short cut between each other. Please tell us about any process for debugging this issue.
I’ve typically used RF switches for this purpose, but that’s also when it was necessary to allow the antenna selection to be changed “in the field”. But for cases where the antenna selection is a manufacture-time option, I’m considering simple zero-ohm resistors.
