Open-top socket for BGA240 provides 27-GHz bandwidth

A new high-performance BGA socket for 1-mm pitch, 240-pin BGA ICs called the SG-BGA-6475 socket is designed for IC size – 17×18-mm package size and operates at bandwidths up to 27 GHz with less than 1 dB of insertion loss. 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 heat sink lid for dissipation of 5 W. The socket comes with ball guide for the precise alignment of BGA balls to PCB pads.

The SG-BGA-6475 socket is constructed with a high-performance and low-inductance elastomer contactor. The temperature range is -35 to +125°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. The socket works with devices such as the 240BGA, 17×18-mm rectangular package with a 15×16 array and 1-mm pitch.

Pricing for the SG-BGA-6475 is $592 at qty 1 with reduced pricing available depending on quantity required.
