Technet,
We have a backplane mounted to a chassis that has many #10 screws holding
it in place. Standard torque specs I use don't indicate what torque is
appropriate for FR-4, and I am fairly certain it would not be the same as
for a metal/metal connection.
Question:
Does anyone have a spec or formula for fastening FR-4 to steel/aluminum
chassis using steel #10 screws (SEMS)?? (Or any size for that matter!!)
I am speculating that FR-4 with pad/pth for screws would compress more then
metal/metal
and am concerned with some damage/fracture to the FR-4 if not torqued
correctly.
Any assistance or information appreciated...
Regards...........DT
