Ironwood Electronics NZGT socket is a device size or near device size footprint test socket incorporating high performance GT elastomer. Ironwood can design a socket to work with any type IC packages- BGA, LGA, QFN, DFN and even leaded devices where you need to fit a socket in place of your device to allow fast, easy testing and development.
The socket footprint is only 1 mm larger (0.5 mm per side) than the device for Near Zero Configurations. Typically this footprint will fit into any end application allowing the Elastomer socket to be directly reflowed into the same location as the device. Depending on the ball configuration (BGA only) some designs can be made to a true Zero Foot Print.
GT is a proven technology used in other Ironwood’s test sockets. It has silver particles held in a conductive column like buttons which are embedded in a non-conductive polymer substrate on a proper pitch that provides high compliance and extreme temperature ranges. GT is available for various packages from 0.35mm to 1.27mm pitch. The contact resistance is <30 milliohms. The operating temperature range for the elastomer is -55C to +160C. GT elastomer will be placed inside the socket after reflow using SMT process.
GTP Elastomer options are also available to double to the possible cycle count when high volume is relevant.
Grypper Sockets are also Near Zero Footprint solutions because they solder directly to the BGA footprint and allow repeated IC exchanges. The IC's simply snap into place and can be thoughoughly tested (in most cases a production board can be utilized rather than requiring a sepatere test circuit). The lifespan of a Grypper can accomodate hundreds of DUTs.
Ironwood Electronics offers IC package adapters and solutions including options for attaching the test sockets to the circuits via epoxy, solder, nuts/bolts or other options.
