High-performance Elastomer Socket from Ironwood Electronics

21 November 2017

Ironwood Electronics recently introduced a new high-performance elastomer socket for 0.4 mm pitch BGA package.

The SG25-BGA-2042 socket is designed for a 4.47 x 4.34 mm package size and operates at bandwidths up to 40 GHz with less than 1dB of insertion loss (GSSG configuration). The contact resistance isSource: Ironwood ElectronicsSource: Ironwood Electronics typically 20 milliohms per pin. Network analyzer reflection measurements for the G-S-S-G case were taken with all except the pins under consideration terminated into 50 Ohms.

The socket is mounted using supplied hardware on the target PCB with no soldering and uses the smallest footprint in the industry. This footprint size allows inductors, resistors and decoupling capacitors to be placed very close to the device for impedance tuning. The socket also incorporates a simple swivel hardware installation method so that ICs can be changed out quickly.

The SG25-BGA-2042 sockets are constructed with a high-performance, low-inductance elastomer contactor. The temperature range is minus 35 degrees to 100 degrees Celsius. The pin self-inductance is 0.06 nH and mutual inductance of 0.019 nH. Capacitance to ground is 0.129 pF and mutual capacitance is 0.017 pF. Current capacity is 2 amps per pin.
