Ironwood Electronics recently introduced a new LGA socket addressing high-performance requirements for custom pitch devices – CBT-LGA-5015. The socket features an IC guide for precise LGA edge alignment. The specific configuration of the package to be tested in the CBT-LGA-5015 is LGA, 3.6×3.6mm body size and 0.514mm pitch. To use, drop IC into the socket, close 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 modules and custom 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. CBT-LGA-5015 socket features a unique contact design with outside spring and flat stamped plungers that provide a robust solution for Burn-in & Test applications including 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 uses 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 ICs can be changed out quickly.
