Patent ID: 7570491

Claim:
A printed circuit board with embedded capacitors therein, comprising: a) a non-copper clad laminate having a plurality of inner via holes formed on its predetermined regions, wherein the via holes define a perimeter; b) a capacitor paste filled in the plurality of inner via holes formed on the non-copper clad laminate, wherein the capacitor paste fills the via holes to the perimeter of the via holes and throughout the height of the via holes; c) copper foil layers provided on both upper and lower surfaces of the capacitor paste and the non-copper clad laminate, the copper foil layers forming top electrodes, bottom electrodes and signal circuit patterns, wherein a top electrode formed by a copper foil layer contacts the top of the capacitor paste at least over the area defined by the perimeter of the via hole and a bottom electrode formed by a copper foil layer contacts the bottom of the capacitor paste at least over the area defined by the perimeter of the via hole and wherein the signal circuit patterns are formed by a copper foil layer juxtaposed next to the top and bottom surfaces of the non-copper clad laminate at the height of the top and bottom electrodes of the capacitor; d) resin coated copper (RCC) layers laminated to the top electrodes, the bottom electrodes and the signal circuit patterns; e) predetermined outer via holes and through-holes formed in the resin coated copper layers; and f) plating layers plated in the inner walls of the outer via holes and the through-holes.
