A new socket addresses high-performance requirements for burn-in and test applications. Called the SBT-BGA-6044, the socket contains a contactor that is a stamped spring pin with 19-gm actuation force per ball and cycle life of 125,000 insertions. The self-inductance of the contactor is 0.93 nH, insertion loss of < 1 dB at 14.1 GHz and capacitance 0.097 pF. The current capacity of each contactor is 4 A at 80°C temperature rise. Socket temperature range is -55 to +180°C. The socket features a floating guide for precise ball-to-pin alignment. The socket also includes an integrated compression plate that has a center opening for accessing the device top surface. The specific configuration of the package to be tested in the SBT-BGA-6044 is BGA, 21×21-mm body size, 1-mm pitch and 19×19 ball array.
To use, the operator drops the IC into the socket, places the lid, and applies down force using four screws alternatively. This socket can be used for hand test and quick turn custom burn-in applications with the most stringent requirements.
Pricing for the SBT-BGA-6044 is $747 at qty 1 with reduced pricing available depending on quantity required.
