75 GHz Bandwidth Heat Sink Uses High Performance Elastomer

The GT-BGA-6008 BGA socket from Ironwood Electronics uses high performance elastomer and operates at bandwidths up to 75 GHz with less than 1 dB of insertion loss and contact resistance at 20 mΩ (typical) per pin. It is designed to dissipate 4.5 Watts using a compression screw with heat sink fins. It can be customized up to 100 Watts with a modified fin design on top of the screw and an added axial flow fan. It is mounted on the target PCB with no soldering and takes up little space, allowing for capacitors and resistors to be placed closed by. It is also constructed with a swivel lid which allows for ICs to be changed out quickly, as well as a center opening for thermocouple and thermal streaming. The socket is designed for a 27 x 27 mm package size.
