High Performance Socket from Ironwood for BGA Testing
High performance BGA test socket.
Eagan, MN — Ironwood Electronics has introduced a new high performance BGA socket for 0.5mm pitch, 3 x 7.5mm Clock Driver IC. The SG-BGA-7244 socket is designed for testing Clock Driver BGA devices and operates at bandwidths up to 10 GHz with less than 1dB of insertion loss.

The contact resistance is typically 20 milliohms per I/O. The socket connects all pins with 10GHz bandwidth on all connections. The socket is mounted using supplied hardware on the target PCB with no soldering, and reportedly uses the smallest footprint in the industry. The socket also incorporates a new quick insertion method using shoulder screws and swivel socket lid so that ICs can be changed out quickly.

The socket also incorporates a floating compression mechanism to accommodate package manufacturing variations. Another special feature of the socket is a torque indicator that applies repeatable compression force to the elastomer. This feature protects the elastomer from damage and assures multiple device insertions. The specific package size accommodated by the socket is 0.5mm pitch, 3 x 7.5mm, 5 x 14 full array BGAs.

The SG-BGA-7244 sockets are constructed with high performance and low inductance gold-plated embedded wire on elastomer as interconnect material between device and PCB. The temperature range is -35 to +100°C. The pin self inductance is 0.15nH and mutual inductance is 0.025nH. Capacitance to ground is 0.01 pF. Current capacity is 2amps per pin.
