Electronics Interconnect BGA Interconnect socketIRONWOOD ELECTRONICS CG25-BGA-2002 socket high performance elastomer socket for 0.5mm pitch BGA package is designed for a 6mmx6mm package size and operates at bandwidths up to 40GHz with less than 1dB of insertion loss (GSSG configuration). The contact resistance is typically 20 milliohms per pin. Network analyzer reflection measurements for the G-S-S-G case were taken with all except the pins under consideration terminated into 50 Ohms. 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. Device incorporates an integrated compression plate inside the clamshell socket lid along with torque indicating compression screw so that IC’s can be changed out quickly and applied proper torque for compression force.
