A high performance printed circuit board assembly, comprising at least two modularized circuitized power plane sub-assemblies adjacently laminated to each other and characterized by X and Y signal planes disposed about an internal power plane, each of said sub-assemblies having a dielectric between said signal and power planes to bond said signal and power planes, and vias disposed within each sub-assembly for providing electrical communication between said signal planes, and whereby a dielectric layer is located between the signal plane in one of the sub-assemblies and an adjacent signal plane in an adjacent sub-assembly. A method of constructing a high performance printed circuit board assembly utilizing a modular construction technique, comprising the steps of: (a) fabricating a first circuitized power core sub-assembly having X-Y signal planes disposed about an internal plane and separated therefrom by means of a dielectric layer; and wherein said X-Y signal planes are electrically connected by plated vias; (b) repeating step (a) to form a number of sub-assemblies; (c) laminating at least two sub-assemblies together to form a composite whereby a signal plane of one sub-assembly is adjacent to a signal plane of another sub-assembly; and (d) constructing a printed circuit board assembly by building a multi-laminate structure using said composite.
