    摘要: A method of making a printed circuit board in which the board includes a common power plane having dielectric layers on opposing sides thereof and a signal layer on each of said dielectric layers, each signal layer comprising a plurality of substantially parallel signal lines running in substantially similar directions across said signal layers. Predetermined portions of the signal lines in one signal layer are aligned relative to and also parallel to corresponding signal lines in the other signal layer, with the power plane being located between these portions. Through hole connections are provided between selected signal lines in the two layers, these occurring through clearance holes in the power plane so as to be isolated therefrom.

    摘要: A method of making a circuitized substrate and an electrical assembly utilizing same in which the substrate is comprised of at least two sub-composites in which the dielectric material of at least one of these sub-composites is heated during bonding (e.g., lamination) to the other sufficiently to cause the dielectric material to flow into and substantially fill openings in a conductive layer for the bonded structure. Conductive thru-holes are formed within the bonded structure to couple selected ones of the structure's conductive layers. Formation of an electrical assembly is possible by positioning one or more electrical components (e.g., semiconductor chips or chip carriers) on the final structure and electrically coupling these to the structure's external circuitry.
