Ironwood Electronics recently introduced a new high-performance BGA socket for 1-mm pitch, 2577 pin BGA ICs. The SG-BGA-6422 socket is designed for IC size 52.5 × 52.5 mm and operates at bandwidths up to 27 GHz with less than 1 dB of insertion loss. The sockets are designed to dissipate up to several watts without extra heat sinking and can handle up to 100 W with custom heat sink. The contact resistance is typically 20 mΩ per pin. The socket connects all pins with 27-GHz bandwidth on all connections. The socket is mounted on the target PCB with no soldering and uses industry’s smallest footprint. The socket is constructed with shoulder screw and swivel lid which incorporates a quick insertion method so that ICs can be changed out quickly. The socket comes with ball guide for the precise alignment of BGA balls to PCB pads.
The SG-BGA-6422 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 mutual inductance of 0.025 nH. Capacitance to ground is 0.01 pF. Current capacity is 2 A per pin. It works with ICs such as Xilinx BGA, 52.5-mm square package with 51 × 51 array and 1-mm pitch.
The SG-BGA-6422 is $1805, with reduced pricing available depending on the quantity required.
