Ironwood Electronics has recently introduced a new high performance BGA socket for 1 mm pitch BGA 937 pin BGA. The CG-BGA-4028 socket is designed for 35 mm x 35 mm package size and operates at bandwidths up to 27 GHz with less than 1 dB of insertion loss. The socket is designed with an easy-open clamshell lid mechanism that enhances user experience when using high pin count devices in the socket.
The socket also features an integrated compression plate that retains force during various environmental conditions. The socket has heatsink with fan for dissipating 6 W. The contact resistance is typically 20 milliohms per pin. The socket connects all pins with 27 GHz bandwidth on all connections. The socket is mounted using supplied hardware on the target PCB with no soldering and uses the smallest footprint in the industry, which allows inductors, resistors and decoupling capacitors to be placed very close to the device for impedance tuning.
The CG-BGA-4028 sockets are constructed with high performance and low inductance elastomer contactor. The temperature range is -35° C to 125° C. The pin self-inductance is 0.11 nH and mutual inductance of 0.028 nH. Capacitance to ground is 0.028 pF. Current capacity is 2 amps per pin.
Pricing for the CG-BGA-4028 is $1,417 each, with reduced pricing available depending on the quantity required.
