High Performance Socket for 0.4mm Pitch QFN
Socket your 104 position QFN without significant performance loss and with minimal increase in PC Board footprint at high temperature
Eagan, MN. - April, 2006 - Ironwood Electronics has recently introduced 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 7 watts over a temperature range of -40C 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 center of the QFN is contacted with 9 additional spring pins for highest bandwidth interface.
The SS-QFN104A-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 1.1nH and with a capacitance to ground of 0.58pF. Current carrying capacity is 1.5 amps per pin. Normal force for actuation is only 20gms per pin with a typical contact resistance of 62 mOhms.
To use, mount the socket onto board, drop in chip, close lid and hand tighten.
Pricing for the SS-QFN104A-01 socket is $1480 at quantity 1 with reduced pricing available depending on quantity required.
