RF test socket

This RF test socket provides a built-in spring-loaded heat-sink to prevent deformation of device leads during testing cycles. The socket is designed for use with QFP, LCC, and SO devices. The heatsink is constructed from copper or aluminum, with gold or silver plating. The spring loading gives compliancy to the heatsink, ensuring that it maintains constant contact with the device's heat pad. The entire socket assembly is pressure-mounted to the load board.
