Patent ID: 8116097

Claim:
An apparatus for coupling an integrated circuit (IC) package to a printed circuit board, the apparatus comprising: an interposer having a plurality of connections suitable for surface mounting on corresponding pads of a printed circuit board (PCB), wherein the plurality of connections is arranged in a grid array, and wherein the interposer includes a plurality of plated through holes; and a substrate coupled to the interposer, wherein the substrate includes a plurality of pins, and wherein the substrate is coupled to the interposer by inserting each of the plurality of pins into a corresponding one of the plurality of plated through holes, and wherein the substrate is configured for mounting of an integrated circuit (IC) package thereon, wherein the substrate includes a plurality of layers including a first layer having a power plane, a second layer having a ground plane, and a third layer having a plurality of signal traces; wherein the interposer includes a plurality of bus bars which provide power and ground connections to the substrate when the substrate and the interposer are coupled together, wherein the bus bars are centrally located on the interposer and extend perpendicularly from the interposer to the substrate when the interposer and substrate are coupled together.
