Ironwood Electronics’ stamped spring pin socket lets you test your 12x12mm BGA device using an extreme temperature socket.
Ironwood Electronics introduced a new stamped spring pin socket to address the high-performance requirements for testing BGA243 – CBT-BGA-7020. The contactor is a stamped spring pin with 31g actuation force per ball with a cycle life of 500,000 insertions.
The self-inductance of the contactor is 0.88 nH, insertion loss is <1dB at 15.7GHz, and capacitance is 0.097pF. The current capacity of each contactor is 4A at +40°C temperature rise with a temperature range of -55°C to +180°C. The socket also features a clamshell lid for ease of operation and has an integrated compression plate for vertical force without distorting device position.
The specific configuration of the package to be tested in the CBT-BGA-7020 is a BGA, 12x12mm, 0.6mm pitch with 243 balls. The socket is mounted using supplied hardware on the target PCB with no soldering required, and has the smallest footprint in the industry. The small footprint allows inductors, resistors, and decoupling capacitors to be placed very close to the device for impedance tuning.
To use, place the BGA device into the socket and close the lid by snapping to the latch. Vertical force is applied by turning the compression screw. This socket can be used for quick device screening and device characterization at extreme temperatures, as well as for final production test.
