Microelectronics Exposed Using 500K Insertion Socket with Superior Electrical Performance

Tue, 07/14/2009 - 10:56am

LISTED UNDER:



The new high performance socket SS-QFE128SD-01 for the Exposed-TQFP128 IC is a spring pin (pogo) with a 20 gram actuation force per ball and cycle life of 500,000 insertions. The self inductance of the contactor is 1.1 nH, insertion loss of 1 dB at 11.5 GHz (3dB at 19.3GHz), and capacitance 0.58pF. The current capacity of each contactor is 1.5 amps. Socket temperature range is -40C to +120C. The specific configuration of the package to be tested in the SS-QFE128SD-01 is QFP, 14x14mm body size, 0.4mm pitch with center E-pad, 16x16mm lead tip to tip. Spring pin sockets are ideal candidates for testing larger current ICs. To use, drop IC into the socket, close clam shell lid, and apply down force using compression screw. This socket can be used for hand tests and burn-in applications with the most stringent requirements.
