IRONWOOD ELECTRONICS Stamped spring pin socket addresses high performance requirements for testing BGA35 – CBT-BGA-7525. The contactor is a stamped spring pin with 8 gram actuation force per ball and cycle life of 75,000 insertions. The self-inductance of the contactor is 0.92nH, insertion loss < 1dB at 24.7GHz and capacitance 0.058pF. The current capacity of each contactor is 1 amps at 20C temperature rise. Socket temperature range is -55C to +180C. Socket features a clamshell lid design for ease of chip replacement in production environment. It also has an integrated compression plate for vertical force actuation without distorting device position.
