Ironwood Electronics recently introduced a new Stamped spring pin socket addressing high performance requirements for testing BGA208 – CBT-BGA-7041. The contactor is a stamped spring pin with 31-g actuation force per ball and 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 capacitance 0.097 pF. The current capacity of each contactor is 4 A at 40°C temperature rise. Socket temperature range is -55C to +180°C. Socket features a clamshell lid design for ease of chip replacement in production environment. It also has an integrated compression plate for vertical force without distorting device position.
The specific configuration of the package to be tested in the CBT-BGA-7041 is a BGA, 14×10-mm, 0.75-mm pitch 16×13 array with 208 balls. The socket is mounted using supplied hardware on the target PCB with no soldering, and uses the smallest footprint in the industry. The smallest footprint allows inductors, resistors and decoupling capacitors to be placed close to the device for impedance tuning.
This socket can be used for quick device screening, device characterization at extreme temperatures as well as final production test.
Pricing for the CBT-BGA-7041 is $863 at qty 1 with reduced pricing available depending on quantity required.
