Ironwood Electronics has introduced a new performance QFN socket for 0.65mm pitch devices. The SS-QFN204A-01 socket, designed for a 12mm package size, operates at bandwidths up to 6.5 GHz with less than 1dB of insertion loss. Designed for up to 500,000 actuation cycles, the socket is able to dissipate up to 4 watts over a temperature range of 
-40 C to +150 C without the need for an additional heat sink. This is all accomplished within a 2.5mm larger border. It accommodates a chip with 204 pins plus ground pad in the center of the QFN is contacted with additional spring pins for highest bandwidth interface.
The SS-QFN204A-01 socket utilizes 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 1.3 nH and with a capacitance to ground of 0.53 pF. Current carrying capacity is 1.5 amps per pin. Normal force for actuation is only 16gms per pin with a typical contact resistance of 82 mΩ. Pricing for the SS-QFN204A-01 socket is $1,905 at quantity 1 with reduced pricing available depending on quantity required.
