Socket Your BGA Package Using Elastomer Socket with Superior Electrical Performance

01 March 2018

Ironwood Electronics recently introduced a new high performance elastomer socket for 0.65 mm pitch BGA Source: Ironwood ElectronicsSource: Ironwood Electronicspackage. The SG25-BGA-2045 socket is designed for a 11 mm x 11 mm package size and operates at bandwidths up to 52 GHz with less than 1 dB 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 the 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 hardware installation method so that ICs can be changed out quickly.

The SG25-BGA-2045 sockets are constructed with high performance and low inductance elastomer contactor. The temperature range is minus 35 degrees Celsius to 100 degrees Celsius. The pin self inductance is 0.06 nH and mutual inductance of 0.019 nH. Capacitance to ground is 0.129 pF and mutual capacitance is 0.017 pF. Current capacity is 2 amps per pin.

Pricing for the SG25-BGA-2045 is $434 at qty 1; reduced pricing is available depending on quantity required.
