Patent ID: 8107254

Claim:
A printed circuit board (‘PCB’) with a capacitor integrated within a via of the PCB, the PCB comprising: layers of laminate; a via comprising a via hole traversing layers of the PCB, the via hole characterized by a generally tubular inner surface; a capacitor integrated within the via, the capacitor comprising: two capacitor plates, an inner plate and an outer plate, the two plates composed of electrically conductive material disposed upon the inner surface of the via hole, both plates traversing layers of the laminate, the inner plate traversing more layers of the laminate than are traversed by the outer plate; a layer of dielectric material disposed between the two plates; and a ground plane formed upon a layer of the PCB and a power plane formed upon another layer of the PCB, the ground plane and the power plane connected through the capacitor so as to bypass alternating current from the power plane to the ground plane.
