Ironwood Electronics has released the XG-LGA-7000 LGA socket for 0.65mm pitch LGA devices designed for a 12mm package size, and operates up to 40GHz with less than 1dB of insertion loss.

The XG-LGA-7000 socket accommodates IC packages such as the 12 x 12 LGA with 0.65mm pads in a 17 x 17 array. The sockets are designed to dissipate up to several watts without extra heat sinking and can handle up to 100W with a custom heat sink. The contact resistance is typically 50m? per pin.

The socket is constructed with a low inductance elastomer with a gold-plated, barbed pad connecting to the IC pad and operates at temperature range of -40C to +155C. The pin self inductance is 0.11nH and mutual inductance is 0.028nH. Capacitance-to-ground is 0.028pF and current capacity is 5A per pin. In addition, the open lid option (XG-LGA-7001) allows probing of die or direct injection of heat or cooling air.

The XG-LGA-7000 is priced at $1,397 each.
