QFN / QFP35 Sockets

High-Performance Test Socket for Engineering Development, Characterization, Failure analysis and Manual testing of QFN, QFP DFN and SO IC Packages

Technical Documents


Test sockets are designed for testing today's high-performance QFN, QFP DFN and SO devices. For development, characterization, at speed burn-in, and low volume production manual testing.

QFN / QFP35 Contact Height

 

The table below is the JEDEC MO-220 listing of the "Thermally Enhanced Thin and Very Thin" QFN devices The Ironwood part number listed designates the socket we have designed for the various standard QFN devices by BODY SIZE LEAD COUNT and PITCH. The design has a press that will accommodate the device thickness in the range of the MIN and MAX listed. If you have a device thickness outside the limits we can accommodate this easily with either a modified press or one from another design The contacts in the center for the ground pad lists the Minimum size the socket will accommodate. Other ground configuration can be designed and Solid ground blocks also can be design for maximum thermal dissipation when required. Ironwood also has 100's of additional designs for other variations of QFN, QFP and DFN and SO devices. Always submit a package drawing so we can ensure the proper fit CAD Footprint drawings are available for all the socket part numbers listed for your PCB layout.
