Abstract
A printed circuit board laminate is disclosed having a high capacitance power distribution core. The power distribution core comprises a pair of conductive plates electrically connected to an array of high capacitance core tiles, separated by a compliant dielectric filler. The resulting capacitance of the power distribution core is sufficient to eliminate the need for decoupling capacitors on a typical printed circuit board. Separate power supply areas of variable decoupling capacitance can be formed for mounted integrated circuits with different power supply requirements. A method for manufacturing such board laminates is also disclosed that is compatible with standard printed circuit board assembly technology.
