Rob,
We do this quite often to attach covers to boards. We use this
procedure after discussions
with our vendors. We put a pad and hole (corresponding to the slot
width) at each end of the slot
and then add the dimensions for the slot on the fabrication drawing.
If you want the slots plated thru,
make the end pads and connecting trace the appropriate size for
proper copper width around the slot.
If the slots are not plated thru, put a pad diameter that will be
routed away.
I believe this was all mentioned already, but anyway, that's how we
do it.
