A new high-performance QFN socket handles 0.15-mm-pitch devices. The SS-QFN184A-01 socket, designed for a 9.2×6-mm package size, operates at bandwidths up to 23.8 GHz with less than 1 dB of insertion loss. Designed for up to 500,000 actuation cycles, the socket is able to dissipate up to 2 W over a temperature range of –40 to +150°C without the need for an additional heat sink. This is all accomplished within a 2.5-mm larger border, the smallest footprint available to the industry. It accommodates a chip with 184 pins at 0.15-mm 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 1.08 nH and with a capacitance-to-ground of 0.4 pF. Current carrying capacity is 0.6 A/pin. Normal force for actuation is only 8 gm per pin with a typical contact resistance of 400 mΩ.
To use, an operator mounts the socket onto a board, drops in the chip, closes the lid and hand tightens.
Pricing for the SS-QFN184A-01 socket is $3,495 at quantity one with reduced pricing available depending on quantity required.
