EAGAN, MN. Ironwood Electronics recently introduced the new CBT-QFE-3018 stamped spring-pin socket addressing high-performance requirements for testing 48-lead quad flat pack devices. The contactor used in CBT-QFE-3018 socket is a stamped spring pin with 17-g actuation force per ball and cycle life of 10,000+ insertions. The self-inductance of the contactor is 0.88 nH, insertion loss is < 1 dB at 31.7 GHz, and capacitance is 0.03 pF. The current capacity of each contactor is 2.9 A. Socket temperature range is -55°C to +180°C.
The socket also features an open-top lid with clamshell latch for ease of operation. The center square opening on the lid allows ease of access to the device top side. The socket lid has an integrated compression plate for vertical force without distorting device position. The socket also features a precise lead-positioning guide that aligns each lead to the corresponding spring pin. The specific configuration of the package to be tested in the CBT-QFE-3018 is a Quad Flat Pack, 7-mm square, 0.5-mm pitch, 9-mm lead tip to tip distance with 48 leads. The socket is mounted using supplied hardware on the target PCB with no soldering. The small footprint allows inductors, resistors, and decoupling capacitors to be placed close to the device for impedance tuning. The center array of spring pins provides good electrical/thermal connection between the ground pad of the device and the target PCB. To use, place QFP device into the socket, close the lid by snapping to the latch, and the downward force is applied by turning the lever from the "open" position to the "test" position. This socket can be used for quick device screening as well as device characterization at extreme temperatures.
Pricing for the CBT-QFE-3018 is $745 each in unit quantities.
