RPi Compute Module - mechanical support?
« on: June 10, 2019, 06:14:05 am »
So I have a Raspberry Pi compute module design. When I did the PCB I put the same 2.3mm holes below where the holes in the CM SODIMM are with the idea of sticking some sort of standoff / spacer in later to provide additional mechanical support in adition to the spring loaded clips of the 200pin DDR2 socket.



Well later has come and I just cannot find anything suitable, for the next run I could enlarge the hole in my PCB but was hoping someone might be able to link me a product that works. I would rather not resort to a plastic spacer, washers, nut & bolt combo if I can help it and was hoping for something more elegant.

These are good but the recommended drill size is 3mm.

Or these solder metal screw mounts, would also be good but again it's a 3.5mm mount hole, but worst the screw is a M2.5 so larger then the holes in the CM.

BTW I hate these double ended snap lock ones with a vengeance, please do not recommend them. :)

Or just tell me I should have put a bigger hole in my PCB :)


Thanks
