Ironwood Electronics, a leading manufacturer of advanced adapters, sockets, and modules has recently introduced a high performance elastomer socket for BGA packages with a 0.5 mm pitch. This CG25-BGA-2002 socket is designed for a 6 mm x 6 mm package size and operates at bandwidths up to 40 GHz 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 the smallest footprint in the industry. The small footprint allows inductors, resistors and decoupling capacitors to be placed very close to the device for impedance tuning. The socket also 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.
The CG25-BGA-2002 sockets are constructed with high performance and low inductance elastomer contactors. They can operate at a temperature range from -35C to +125 C. The pins have self inductance of 0.06 nH and mutual inductance of 0.019 nH. The capacitance to ground is 0.129 pF and mutual capacitance is 0.017 pF. The current capacity is 2 amps per pin.
Pricing for the CG25-BGA-2002 is $530 per socket; with reduced pricing available for higher quantities.
Ironwood Electronics will be showcasing this product, along with other products from their portfolio at IMS 2022 in Denver next week. Stop by their booth to learn more.
