Ironwood offers 27-GHz open-top socket for BGA121

Feb. 2, 2017

Eagan, MN. Ironwood Electronics has introduced a new high-performance BGA socket for 1-mm pitch, 121-pin BGA ICs. The SG-BGA-6457 socket is designed for 12 x 12-mm package sizes 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 what the vendor says is the industry’s smallest footprint. The socket is constructed with open-top lid for access to the center of IC package. The socket comes with ball guide for the precise alignment of BGA balls to PCB pads.

The SG-BGA-6457 socket is constructed with high-performance and low-inductance elastomer contactor. The temperature range is -35 to +100°C. The pin self-inductance is 0.15 nH, and mutual inductance is 0.025 nH. Capacitance to ground is 0.01 pF. Current capacity is 2 A per pin.

Pricing for the SG-BGA-6457 is $318 in unit quantities, with reduced pricing available depending on quantity required.
