A new high-performance elastomer socket is designed to handle 0.5-mm-pitch BGA packages. The CG15-BGA-1003 socket is designed for a 10×5.7-mm package size and operates at bandwidths up to 40 GHz with less than 1 dB of insertion loss (GSSG configuration). The contact resistance is typically 20 mΩ 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 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 an integrated compression plate inside the clamshell socket lid so ICs can be changed out quickly. The socket is constructed with a cam-actuated lever lid with central heatsink and a fan for 5.3-W power dissipation. To use, the operator places the device inside the socket, closes the clamshell lid by latching and applies downward pressure by turning the lever. This socket can be used for hand-test and temperature characterization as well as for debugging applications in development platforms.
The CG15-BGA-1003 sockets are constructed with high performance and low inductance elastomer contactor. The temperature range is -35 to +125°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 CG15-BGA-1003 is $995 at qty 1; with reduced pricing available depending on the quantity required.
