ESC : San Jose, Ca. -- Ironwood Electronics has introduced a high performance socket for processor with a POP memory socketed on top.
The SG-BGA-7116 socket is designed for socketing a 0.4mm ball grid array (BGA) IC, a 12x12mm body with 28x28 ball array to a target PCB and in addition, socket a POP memory on top with 12x12mm, 0.5mm pitch, 23x23 array, and Samsung 12x12mm 168 ball fine pitch BGA package.
The contactors are designed for a 12mm package size, and operate at bandwidths up to 40 GHz with less than 1dB of insertion loss. The socket is designed to dissipate up to several watts without extra heat sinking and can handle more with custom heat sink.
The contact resistance is typically 100 milliohms per pin. Installation is quick and easy with first attaching the socket to the PCB, insert first IC in Stack, insert second contactor and IC, and tightening compression mechanism.
The SG-BGA-7116 is constructed with high performance and low inductance elastomer on both socketing levels with a gold plated, barbed pad connecting to the IC Pad. The temperature range is -40 C to +100 C. The pin self-inductance is 0.11 nH and mutual inductance of 0.028 nH. Capacitance to ground is 0.028 pF. Current capacity is 5 amps per pin.
