We have a high power application where the engineers want to use press-fit
components that are like metal blocks with a grid of pins underneath that
need to be smooshed into the board. You can see a picture at
http://frontdoor.biz/PCBportal/wurth.jpg
The manufacturer gives enough data about insertion force and max torque and
all that, but it just got me wondering... some of these devices have 36 pins
and at 250 N per pin (max) this seems like a lot of pressure. Can boards be
damaged by so much pressure? (assuming we prevent warping). Seems like there
would have to be some limit to compressive force on laminate, but I've never
heard anyone mention it.
