www.connect.co.jp www.jccherry.com Latch Lock type Latch Lock and Screw Lock type Direct Contact Socket for QFP,SOP etc. Screw Lock type Rotary lever type The test socket that enables high-speed transmission signal measurement by adopting the contact method that directly presses the device lead against the board. Applications Mounting on PCB for mass-production Final test and inspection at real environment(ex. automobile, robotics, electrical devices for mobility) IC failure analysis Specifications (Typical) Pitch Temperature Range Acceptable device type Acceptable device size * Please contact us for bigger size. There have limited on the number of pins. Features： Since the general IC socket has terminals (spring probe, plate vane, etc.) between the board and the device, the number of contacts are increases, and signal would occurs deterioration or attenuation, but this socket is in a state close to soldering. It's the ideal for evaluating high-speed IC devices because it suppresses the deterioration of the signal.
