The contactor is a stamped spring pin with 31 gram actuation force per ball and cycle life of 125,000 insertions. The self-inductance of the contactor is 0.88nH, insertion loss < 1dB at 15.7GHz and capacitance 0.097pF. The current capacity of each contactor is 4 amps at 40C temperature rise. Socket temperature range is -55C to +180C. Socket features a clamshell lid design for ease of chip replacement in production environment along with precise ball to pin alignment via floating pin guide. It also has an integrated compression plate for vertical force actuation without distorting device position. The specific configuration of the package to be tested in the CBT-BGA-6122 is a BGA, 13x13mm, 0.8mm pitch 16×16 array with 256 balls. The socket is mounted using supplied hardware on the target PCB with no soldering, and uses the smallest footprint in the industry.
