I like this idea of building the modules on top of FR-4 boards. However,
this leaves me unclear on how I should interface the modules to the
backplane. The "postage stamp" idea was appealing, but I am not sure how
I would attach the pins. I know I don't want to be trying to drill very
precise holes, or to be scratching out 20 little islands on the copper.
Any further thoughts on this?
