Elastomer Socket Targets High-Speed SOICs

Operating at bandwidths up to 10 GHz with less than 1 dB insertion loss, Ironwood Electronics’ SG-SOIC-3005 socket is intended for 0.5-mm-pitch, 10-pin SOICs. The socket consists of low-inductance, gold-plated embedded wire on elastomer as an interconnect material between the device and printed-circuit board (PCB). The device measures 3 by 3 by 1 mm, with a 5-mm lead tip to tip with an exposed pad on the bottom. Its small footprint allows for very close placement of inductors, resistors, and decoupling capacitors to the device for impedance tuning. Contact resistance is typically 20 mΩ per I/O. Operating temperature ranges from −35 to +100°C. Pin self-inductance is 0.15 nH, with mutual inductance of 0.025 nH. Current capacity is 2 A per pin. The socket mounts onto the target PCB with supplied hardware; no soldering is required. ICs can be changed out quickly thanks to a swivel lid with compression screw.
