Extreme temperature sockets for 293-pin BGA chips

A new BGA socket addresses high-performance requirements for microcontroller units. Called the – CBT-BGA-6071, the socket contactor is a stamped spring pin with 31-gm actuation force per ball and a cycle life of 125,000 insertions. The self-inductance of the contactor is 0.88 nH, insertion loss < 1 dB at 15.7 GHz and contact resistance is <30 mΩ. 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-6071 is a BGA, 17x17-mm, 0.8-mm pitch, 293-position, 20x20 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. Socket uses a five-post stiffener plate to support the back side of the PCB and allows passive components to be placed between posts. This socket utilizes a clamshell lid with an integrated compression mechanism.

To use the socket, an operator places the BGA device in the socket base and closes the clamshell lid assembly onto the base using the latch. Turning the compression screw handle applies downward pressure via integrated compression plate. This socket can be used for hand test and temperature characterization as well as debugging applications in development and MCU comparison between various manufacturers.

Pricing for the CBT-BGA-6071 is $950 at qty 1 with reduced pricing available depending on quantity required.
