Removable lid spring pin socket from Ironwood Electronics handles DDR memory

A new BGA socket addresses high-performance requirements for DDR. Called the CBT-BGA-6081, the contactor is a stamped spring pin with 31-g actuation force per pin and cycle life of 125,000 insertions. The self-inductance of the contactor is 0.88 nH, insertion loss is below 1 dB at 15.7 GHz, and capacitance is 0.097 pF. The current capacity of each contactor is 4 A at a 30°C temperature rise. Socket temperature range is -55 to +180°C.

The socket also features a ball guide for precise device alignment. The specific configuration of the package to be tested in the CBT-BGA-6081 is BGA, 8×14-mm body size and 0.8-mm pitch. To use, an operator drops an IC into the socket, then closes the removable lid by latching. Vertical force is applied by the integrated compression springs between the socket lid and compression plate. This socket can be used for hand test, screening DDRs and burn-in applications with the most stringent requirements.

These socket product lines have been designed to the JEDEC STD and are available for all standard configurations. Custom designs are also available. The CBT-BGA-6081 socket features a special contact design with outside spring and flat stamped plungers that provide a robust solution for burn-in and test applications with excellent electrical signal integrity to meet the requirements of today’s demanding analog, digital, RF, Bluetooth and medical device applications.

The socket is mounted using supplied hardware on the target PCB with no soldering, and sits in the smallest footprint in the industry. The smallest footprint allows inductors, resistors and decoupling capacitors to be placed very close to the device for impedance tuning. The removable socket lid incorporates a quick installation method using latch so that IC’s can be changed out quickly.

Pricing for the CBT-BGA-6081 is $654 at qty 1 with reduced pricing available depending on quantity required.
