Ironwood Electronics has introduced a new QFN socket addressing high-performance requirements for custom size devices. This Removable Lid Spring Pin Socket for QFN packages can operate at extreme temperatures with excellent electrical performance. The CBT-QFN-7071 socket product lines have been designed for the JEDEC STD and are available for all standard configurations. Custom designs are also available.
The CBT-QFN-7071 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 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 a latch so that IC's can be changed out quickly.
The CBT-QFN-7071 contactor is a stamped spring pin with 14.5-gram actuation force per pin and a cycle life of 100,000 insertions. The self-inductance of the contactor is 0.98 nH, insertion loss of < 1 dB at 31.7 GHz, and capacitance 0.067pF. The current capacity of each contactor is 4 amps. Socket temperature range is -55C to +180C. Socket also features an IC guide pocket inside the top pin guide for precise QFN edge alignment. The specific configuration of the package to be tested in the CBT-QFN-7071 is QFN, 5.4x4.4mm body size, and 0.5mm 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 the compression plate. The compression plate has fins and acts as heat dissipater by contacting the integrated heat-slug of the package. This socket can be used for hand tests, screening modules, and custom burn-in applications with the most stringent requirements.
Pricing for the CBT-QFN-7071 is $630 at qty 1 with reduced pricing available depending on the quantity required.
