ABSTRACT:
A circuitized substrate designed to substantially eliminate impedance disruptions during passage of signals through signal lines of the substrate's circuitry. The substrate includes a first conductive layer with a plurality of conductors on which an electrical component may be positioned and electrically coupled. The pads are coupled to signal lines (e.g., using thru-holes) further within the substrate and these signal lines are further coupled to a second plurality of conductive pads located even further within the substrate. The signal lines are positioned so as to lie between the substrate's first conductive layer and a voltage plane within a third conductive layer below the second conductive layer including the signal lines. A second voltage plane may be used adjacent the first voltage plane of the third conductive layer. Thru-holes may also be used to couple the signal lines coupled to the first conductors to a second plurality of conductors which form part of the third conductive layer. A method of making the substrate, and an electrical assembly and information handling system (e.g., computer) utilizing the substrate are also disclosed.
