Socket your 184 position QFN without significant performance loss and with minimal increase in PC Board footprint at high temperature
Ironwood Electronics has recently introduced a new high performance QFN socket for 0.15mm pitch devices. The SS-QFN184A-01 socket, designed for a 9.2mmx6mm package size, operates at bandwidths up to 23.8GHz with less than 1dB of insertion loss. Designed for up to 500,000 actuation cycles, the socket is able to dissipate up to 2 watts over a temperature range of –40C to +150 °C without the need for an additional heat sink. This is all accomplished within a 2.5mm larger border, the smallest footprint available to the industry. It accommodates a chip with 184 pins at 0.15mm pitch.
The SS-QFN184A-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 1.08nH and with a capacitance to ground of 0.4pF. Current carrying capacity is 0.6 amps per pin. Normal force for actuation is only 8gms per pin with a typical contact resistance of 400 mOhms.
To use mount the socket onto board, drop in chip, close lid and hand tighten.
