Hello all- happy New Year.
I have an application where I need to mount a daughterboard in parallel with a baseboard, with a separation of approx 10mm. This connection will handle power and signaling- 1A per pin max- between the boards. Pin count is < 20.
I have read an excellent book on vibration analysis for electronic equipment, but it focuses on single boards, or snubbers between multiple boards. There is little if any info on interconnections between boards.
Having seen the internals on some ECUs, most do not have removable daughtercards; what exists (that I have seen of commercial designs) is largely soldered boards (SIP style) perpendicular to the main board.
So I was wondering if anyone has any guidance on connector type that is appropriate for a typical automotive ECU-type device in a typical automotive environment (<1G <100hz type stuff). I can do a lot to stabilize the daughtercard to the mainboard- to at least minimize relative motion at the connector. But I wondered if a standard SIP/DIP IDC pin/socket approach is workable, or if I need something more advanced (and probably, expensive). I know there are a ton of variables- just looking for any generalized guidance you might offer-
Best,
R
