New high-performance elastomer sockets for 0.4-mm pitch BGA packages are designed for a 12×12-mm package size and operate at bandwidths up to 65 GHz with less than 1 dB of insertion loss (GSSG configuration). Developed by Ironwood Electronics, the SG25-BGA-2032 socket has a contact resistance of typically 20 mΩ/pin. Network analyzer reflection measurements for the G-S-S-G case were taken with all except the pins under consideration terminated into 50 Ω. 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 sit close to the device for impedance tuning. The socket also incorporates a simple swivel hardware installation method so ICs can be changed out quickly.
The SG25-BGA-2032 sockets are constructed with a high-performance and low-inductance elastomer contactor. The temperature range is -35 to +100°C. 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 A/pin.
Pricing for the SG25-BGA-2032 is $447 at qty 1; with reduced pricing available depending on quantity required.
