Marko,

Thanks! I think I have a rough idea of the meaning now. Can you tell me a 
couple manufacturers of such things so I can get a couple pictures off the web?

Regards,
Lauren

Hi Lauren,

Yay, a question that I can answer!

"Compliant pin" is a through-hole pin-in-via system that physically presses the 
pins inside the plated via barrels. The pins need to have some 'compliancy' so 
that they deform and provide mechanical retention. Sort of like a nail in wood 
except the 'nail' (pin) is soft and the wood (pcb via) is hard.

"C-press" just refers to the cross-section profile of the pin. In this case, 
the x-section is in the form of a "C".

EU RoHS has a couple exemptions related to lead used in a “C-press compliant 
pin connector systems”. Could someone tell me what a C-press compliant pin 
connector system is?

I’ve tried Google, but I only get hits on RoHS and everyone’s reiteration of 
the RoHS exemptions.
