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.

Ironwood Electronics recently introduced a new high-performance BGA socket for 1-mm pitch, 2577 pin BGA ICs. The SG-BGA-6422 socket is designed for IC size 52.5 × 52.5 mm and operates at bandwidths up to 27 GHz with less than 1 dB of insertion loss. The sockets are designed to dissipate up to several watts without extra heat sinking and can handle up to 100 W with custom heat sink. The contact resistance is typically 20 mΩ per pin. The socket connects all pins with 27-GHz bandwidth on all connections. The socket is mounted on the target PCB with no soldering and uses industry’s smallest footprint. The socket is constructed with shoulder screw and swivel lid which incorporates a quick insertion method so that ICs can be changed out quickly. The socket comes with ball guide for the precise alignment of BGA balls to PCB pads.
The SG-BGA-6422 socket is constructed with high performance and low inductance elastomer contactor. The temperature range is –35°C to 100°C. The pin self inductance is 0.15 nH and mutual inductance of 0.025 nH. Capacitance to ground is 0.01 pF. Current capacity is 2 A per pin. It works with ICs such as Xilinx BGA, 52.5-mm square package with 51 × 51 array and 1-mm pitch.
The SG-BGA-6422 is $1805, with reduced pricing available depending on the quantity required.
