Ironwood: Hi-Performance BGA Socket
Hi-performance BGA socket.
Burnsville, MN — Ironwood Electronics has recently introduced a new high-performance BGA socket for 0.65mm pitch 588-pin BGA. The SG-BGA-7181 socket is designed for 13.5 x 25.2 x 1.95mm package size and operates at bandwidths up to 10GHz 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 has the smallest footprint in the industry. This small footprint allows inductors, resistors and decoupling capacitors to be placed very close to the device for impedance tuning. The socket also incorporates a new quick-insertion method so that ICs can be changed out quickly.
The socket is intended to verify the function of an IC in a development system — specifically memory functions.
The SG-BGA-7181 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 0.01pF. Current capacity is 2 amps per pin.
