A new stamped-spring pin socket handles high-performance requirements for testing BGA1164 – CBT-BGA-7042. From Ironwood Electronics, the contactor is a stamped spring pin with 31-g actuation force/ball and cycle life of 125,000 insertions. The self-inductance of the contactor is 0.88 nH, insertion loss is < 1 dB at 15.7 GHz and capacitance is 0.097pF.
The current capacity of each contactor is 4 A at 40 C temperature rise. Socket temperature range is -55 to +180°C. Socket features a lever actuated clamshell lid design for ease of chip replacement in production environments. It also has an integrated compression plate for vertical force actuation without distorting device position. The specific configuration of the package-to-be-tested in the CBT-BGA-7042 is a BGA, 25×25 mm, 0.65-mm pitch 36×36 array with 1,164 balls. The socket mounts using supplied hardware on the target PCB with no soldering and uses the smallest footprint in the industry. The footprint allows inductors, resistors and decoupling capacitors to sit close to the device for impedance tuning.
In operation, vertical force is applied by turning the lever from open to closed position. The socket features a heat sink with fan for 10-W power dissipation and can be customized for higher power dissipation by upgrading to higher flow fan or larger heat sink. This socket can be used for quick device screening, device characterization at extreme temperatures, as well as for final production test.
Pricing for the CBT-BGA-7042 is $1,945 at qty 1 with reduced pricing available depending on quantity required.
