QFN socket is tough
enough for test duties
Ironwood Electronics has a new high performance QFN socket for 0.4mm pitch devices
The SS-QFN104A-01 socket, designed for a 12mm package size, operates at bandwidths up to 11.5GHz with less than 1dB of insertion loss. Designed for up to 500,000 actuation cycles, the socket is able to dissipate up to 7W over a temperature range of -40 to +120C without the need for an additional heatsink.

This is all accomplished within a 2.5mm larger border, the smallest footprint available to the industry.
It accommodates a chip with 104 pins plus ground pad in the centre of the QFN is contacted with nine additional spring pins for maximum interface bandwidth.
The SS-QFN104A-01 socket uses high endurance spring pins, which allow for product use in multiple applications including burn-in, production test and prototype development.
In addition to its wide temperature range and high endurance the pin operates with an inductance of 1.1nH and with a capacitance to ground of 0.58pF.
Current carrying capacity is 1.5A per pin.
Normal force for actuation is only 20g per pin with a typical contact resistance of 62mohm.
The sockets are available in Europe from Logic Technology.
