Ironwood Electronics has expanded its high-performance socket line with the addition of an 11.5GHz socket for 12-pin, 0.4mm pitch QFN ICs. The SS-QFN12D-01 devices allow users to socket QFN ICs without compromising performance in high-bandwidth applications.

The SS-QFN12D-01 sockets (<-1dB at 11.5GHz) support very dense pitch QFN devices. They can dissipate up to 7W without extra heat sinking and can handle up to 100W with a custom heat sink. The contact resistance is typically 80 milliohms per pad.

The SS-QFN12D-01 sockets are constructed with high endurance pogo spring pins and are rated for 500,000 actuations. The temperature range is -40C to 120C, which allows the sockets to be used to test the product over burn-in and high-temperature test applications. The pin inductance is 1.1nH, and capacitance-to-ground is 0.58pF. Each pin requires 20 grams force for actuation and typical pin resistance is 62 milliohms. The socket footprint only requires a 2.5mm border around the IC.

Pricing for the SS-QFN12D-01 socket adapter is $696 each in a single quantity.
