A new BGA socket called the CBT-BGA-6087 features a contactor in the form of a stamped spring pin with 19-gm actuation force per ball and a cycle life of 125,000 insertions. The self-inductance of the contactor is 0.93 nH, insertion loss < 1 dB at 14.1 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-6087 is a BGA, 31×31 mm, 1-mm pitch, 676 position, 30×30 ball array. The socket is mounted using supplied hardware on the target PCB with no soldering and uses a small footprint to accommodate 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 a clamshell lid with an integrated compression mechanism. The socket is constructed with a cam-actuated lever lid with central heatsink and fan to handle an 11-W power dissipation. A Type K thermocouple is placed in the middle of the heatsink to measure the case temperature of the BGA. To use, an operator places the device inside the socket, closes the clamshell lid by latching and applies downward pressure by turning the lever. This socket can be used for hand-test and temperature characterization as well as debugging applications in development platform.
Pricing for the CBT-BGA-6087 is $1,413 at quantity one with reduced pricing available depending on quantity required.
