IRONWOOD SBT-QFE-3035 socket addresses high performance requirements for burn-in and test applications. The contactor is a stamped spring pin with 14 gram actuation force per ball and cycle life of 125,000 insertions. The self-inductance of the contactor is 0.88nH, insertion loss of <1 dB at 20.5GHz and capacitance 0.097pF. The current capacity of each contactor is 2.9 amps. Socket temperature range is -55C to +180C. Product features a floating guide for precise lead to pin alignment. Device also includes additional floating compression plate that has a cavity to accommodate mold case. The specific configuration of the package to be tested is QFP, 16x16mm body size, 0.65mm pitch and 19mm lead tip to tip distance. To use, drop IC into the socket, place floating compression plate, screw down the lid, and apply down force. This socket can be used for hand test and quick turn custom burn-in applications with the most stringent requirements.
