The Ironwood Electronics 75GHz clamshell socket for BGA1156 allows users to quickly and easily socket 1mm-pitch, 34×34-array, 1156BGA packages on any application board with the performance equivalent of the direct-solder version.
Ironwood Electronics introduced a new BGA socket design that uses high-performance elastomer capable of 75GHz, very low inductance, and wide temperature applications. The GT-BGA-2029 socket is designed for 35x35mm package size and operates at bandwidths up to 75GHz with less than 1dB of insertion loss.
The socket is designed to dissipate few watts using compression screw and can be customized up to 100 watts with modified fin design on top of the screw and an added axial-flow fan. The contact resistance is typically 30 milliohms per pin.
The socket is mounted on the target PCB without soldering, in a very small footprint that allows capacitors/resistors to be placed close by. Other passive components can be placed on the back side of the PCB by creating custom cutouts in the stiffener plate.
The socket is constructed with a clamshell lid, which incorporates a quick-insertion method so that ICs can be changed out quickly. To use, place the device inside the socket, close the lid by latching, and apply downward pressure by turning the compression screw.
The GT-BGA-2029 socket is constructed with a high-performance and low-inductance elastomer contactor. The temperature range is -55°C to +160°C. The socket works with ICs such as BGA 35x35mm with 34×34 array and 1mm pitch.
