Ironwood Electronics, a provider of high performance test sockets and adapters for both engineering and production use, has released the CBT-QFN-7033, a new stamped spring pin socket addressing high performance requirements for testing DFN6 electronic filters.
“To test electronic filters, a high performance contact is needed,” the company said. “The contactor used in CBT-QFN-7033 socket is a stamped spring pin with 34 gram actuation force per ball and cycle life of 10,000+ insertions. The self inductance of the contactor is 0.9 nH, insertion loss is less than 1 dB at 9.1 GHz and capacitance 0.03pF. The current capacity of each contactor is 2.2 amps. Socket temperature range is -55C to +155C.”
Able to accommodate two DFN devices, the socket features a clamshell lid for ease of operation and a wave spring with swivel compression plate for vertical force without affecting device position. The socket can be mounted using supplied hardware on the target PCB without the need for soldering. According to the company, the socket uses the smallest footprint in the industry, enabling inductors, resistors and decoupling capacitors to be placed very close to the device for impedance tuning. It can also be used for quick device screening, device characterization at extreme temperatures and final production testing.
