27 GHz Bandwidth DDR3 SDRAM Socket for PBGA543 Quickly and easily Socket your 23x32mm, 1mm pitch BGA543 packages on any PCB without significant performance loss
Ironwood Electronics has recently introduced a new high performance BGA socket for 1mm pitch, 543 pin BGA IC’s. The SG-BGA-6485 socket is designed for IC size – 23x32mm package size and operates at bandwidths up to 27 GHz with less than 1dB of insertion loss. The contact resistance is typically 20 milliohms per pin. The socket connects all pins with 27 GHz bandwidth on all connections. The socket is mounted on the target PCB with no soldering, and uses industry’s smallest footprint. The socket is constructed with swivel lid for easy chip replacement. The socket comes with ball guide for the precise alignment of BGA balls to PCB pads.
The SG-BGA-6485 socket is constructed with high performance and low inductance elastomer contactor. The temperature range is -35 C to +125 C. The pin self inductance is 0.15 nH and mutual inductance of 0.025 nH. Capacitance to ground is 0.01 pF. Current capacity is 2 amps per pin. Works with memory devices such as 543BGA, 23x32mm rectangular package with 21×26 array and 1mm pitch.
Pricing for the SG-BGA-6485 is $936 at qty 1; with reduced pricing available depending on quantity required.
