Clamshell Spring Pin QFN Socket

Ironwood Electronics recently introduced a new QFN socket addressing high performance requirements for testing QFN devices – CBT-QFN-7039. The contactor is a stamped spring pin with 17-g actuation force per ball and cycle life of 50,000 insertions. The self inductance of the contactor is 0.75 nH, insertion loss less than 1 dB at 31.7 GHz. The current capacity of each contactor is 1.5 A at 20°C temperature rise. Socket temperature range is –55°C to 180°C.Ironwood-C14132a_highres

The socket also features an alignment guide for precise device to pin alignment. The specific configuration of the package to be tested in the CBT-QFN-7039 is a QFN, 3 × 3 mm, 0.5-mm pitch, 10 positions with center ground pad. The socket is mounted using supplied hardware on the target PCB with no soldering. To use, place the QFN device into the socket base and lock the double latch socket lid on to the base using the latch.

The socket uses a compression wave spring to apply constant downward pressure enabling the device be interconnected to the target PCB. This socket can be used for hand test and quick device screening applications with the most stringent requirements.

The CBT-QFN-7039 costs $552 with reduced pricing available depending on quantity required.
