A new BGA socket addresses high-performance requirements for MCUs. Caleed the CBT-BGA-6090, its contactor 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 < 1 dB at 14.1 to 21.9 GHz and contact resistance is <30mΩ. The current capacity of each contactor is 4 A at 60°C temperature rise. Socket temperature range is -55 to +180°C. The socket also features a floating guide for precise ball to pin alignment. The specific configuration of the package to be tested in the CBT-BGA-6090 is a BGA, 55x70-mm, 1-mm pitch, 3589-position, 54×69 ball array. The socket is mounted using supplied hardware on the target PCB with no soldering and uses the smallest footprint for nearby passive components. The socket uses a stiffener plate to support the back side of the PCB and allows passive components to be placed via customized pockets.
This socket utilizes double-latch clamshell lid with integrated compression mechanism. The socket is constructed with a cam-actuated lever lid with central copper heatsink with axial fan for dissipating 200 W. To use, an operator places the device inside the socket, closes the clamshell lid by latching and applies downward pressure by turning lever. This socket can be used for hand test and temperature cycling as well as debugging applications in development and device characterization.
Pricing for the CBT-BGA-6090 is $4,106 at qty 1 with reduced pricing available depending on the quantity required.
