Socket handles 47.5-mm square, 1-mm pitch, 2104-pin BGAs

Designed for 47.5 x 47.5-mm, 1-mm-pitch, 2104-pin BGA ICs such as Xilinx FPGAs,
the SG-BGA-6450 high-performance BGA socket operates at bandwidths up to 27 GHz
with less than 1-dB insertion loss. The sockets are also designed to dissipate
few watts; it uses an aluminum compression screw and can be customized with
fins and axial flow fan for higher-power dissipation.

The
socket supports 27 GHz on all pins with a typical contact resistance of 20 mΩ
per pin. The socket mounts on the target PCB with no soldering, and employs a shoulder
screw and a swivel lid that allow ICs to be changed out quickly. Constructed
with a high-performance, low-inductance elastomer contactor, the socket comes
with ball guide for the precise alignment of BGA balls to PCB pads.

With a temperature
range of −35°C to 100°C, the socket has a pin self-inductance of 0.15 nH, mutual
inductance of 0.025 nH, capacitance to ground of 0.01 pF, and current capacity of
2 A per pin. Units are priced at $985 in
single quantities, with reduced pricing in higher volumes.
