Hello everyone,

I am working on an RF design which has 2 boards, essentially a "sandwich".

The bottom board has the digital stuff and 18 relays.  The relays have
physical connections on the top and bottom of the case (Coil on the bottom
and contacts on the top). The top board has all the nasty RF.

There is also a 4 pin header connecting the 2 boards together.

I have footprinted the relays in 2 parts, coil and contacts.

What is the best way to ensure that the 2 boards mate exactly.  When
assembled, the top board goes down on top of the relays with the contacts
sticking through the PCB and is soldered on the top along with the header.

Any input is greatly appreciated!

Thanks,
Glenn
