Hi Frequency Elastomer Socket for very fine pitch – 0.25 mm flip chip
Ironwood Electronics has recently designed a new 0.25 pitch socket using high performance elastomer capable of 75 GHz, very low inductance and wide temperature applications. The 1280 WLCSP socket is designed for 10 x 8 mm package size and operates at bandwidths up to 75 GHz with less than 1dB of insertion loss. The contact resistance is typically 20 milliohms per pin. The socket is mounted on the target PCB with no soldering, and uses very small real estate allowing capacitors/resistors to be placed close by. This socket utilizes bolt on lid with integrated compression mechanism. To use, place the device inside the socket, place the lid and adjust the compression screw to the required torque. This socket can be used for hand test and temperature cycling as well as debugging application in development and device characterization.
The 1280 WLCSP socket is constructed with high performance and low inductance elastomer contactor. The temperature range is -55 °C to +160 °C. Ironwood Electronics can design similar sockets for your fine pitch applications !!
