Has anyone had any experience in using SMT to mount an organic (FR-4, Getek) rider card onto an organic (FR-4, Getek) mother board? By SMT I mean the attachment of the rider card would be through pads directly to pads on the mother board. Than

Like all who post messages here, I'm looking for a little bit (well, maybe a lot of bit) of help. We're currently going through a redesign of a board which will utilize several FPGAs. The manufacturer (Xilinx) recommends using solder mask defined p
