Socket your 483 pin BGA packages on any PCB without significant performance loss and without soldering
Ironwood Electronics has recently introduced a new high performance BGA socket for 0.5mm pitch BGA 483 pin IC’s. The SG-BGA-7345 socket is designed for 11×12.7mm BGA package and operates at bandwidths up to 30 GHz with less than 1dB of insertion loss. The contact resistance is typically 20 milliohms per pin. The socket connects all pins with 30 GHz bandwidth on all connections. The socket is mounted using supplied hardware on the target PCB with no soldering, and uses smallest footprint in the industry. The smallest footprint allows inductors, resistors and decoupling capacitors to be placed very close to the device for impedance tuning. The socket also incorporates a simple swivel lid hardware installation method so that IC’s can be changed out quickly.
The SG-BGA-7345 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 0.15 nH and mutual inductance of 0.025 nH. Capacitance to ground is 0.01 pF. Current capacity is 2 amps per pin. Elastomer requires proper force for operation which is applied through a torque limiting driver via compression screw. Typical IC’s that can be tested using this socket have 483 balls, 11×12.7mm with 0.5mm pitch and 21×23 ball array.
