Ironwood Electronics recently introduced a new high performance BGA socket for 1-mm pitch, 1760 pin BGA ICs. The SG-BGA-6348 socket is designed for 42.5-mm x 42.5-mm package size and operates at bandwidths up to 8 GHz with less than 1 dB of insertion loss. The sockets are designed to dissipate 35 W with active heat sinking (forced convection using a DC fan). The contact resistance is typically 20 milliohms per pin. The socket connects all pins with 8 GHz bandwidth on all connections. The socket is mounted on the target PCB with no soldering, and uses a small footprint (only 2.5 mm more on each side). The socket is constructed with screw mounting which allows a quick insertion method so that ICs can be changed out quickly. The SG-BGA-6348 socket is constructed with high performance and low inductance elastomer contactor. The temperature range is -35 C to +100 C; the pin self inductance is 0.15 nH; and the mutual inductance is 0.025 nH. Capacitance to ground is 0.01 pF. Current capacity is 2 A per pin. The socket works with ICs such as Kyocera FCBGA.
