Function

Pressure Conductive Silicone Rubber (PCR) is a common contact solution for IC package testing. It operates through a matrix of conductive particles uniformly dispersed within a silicone base. Under compression, these particles align to create a low-impedance path, establishing a stable electrical connection between the IC chip and the PCB without the need for soldering.

Characterized by low contact resistance, high current capacity, and a non-marring surface, PCR is an ideal choice for high-speed signal transmission and high-pin-count applications.
