Ironwood: Socket for 56-Pin QFN Packages
Test socket and cooling fan.
Eagan, MN — Ironwood Electronics has introduced a new high performance QFN socket for 0.4mm pitch QFN 56 pin ICs. The DG-QFN56B-01 socket is designed for a 7 x 7mm package size and operates at bandwidths up to 40GHz with less than 1dB of insertion loss.

The socket is designed to dissipate 12 watts with lid-mounted heat sink and fan. The contact resistance is typically 3 milliohms per pin. The socket connects all pins and the center ground pad with 40GHz bandwidth. The socket is mounted on the target PCB with no soldering, and uses what is said to be the industry's smallest footprint — only 2.5mm more on each side. 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 is constructed with high-performance and low-inductance diamond particle interconnect contactor. The contactor is capable of supporting 100,000 insertions. The temperature range is -70 to +200°C.
