Abstract
A printed circuit board including a terminated power plane is described. Specifically, the power-ground plane construction includes a dielectric layer, a power plane having a peripheral edge, and a ground plane. The ground plane is spaced from the power plane by the dielectric layer, and is positioned in an opposed relationship to the power plane. The power-ground plane construction also includes a termination element coupling the power plane, at or adjacent the peripheral edge thereof, to the ground plane so as to terminate the power plane. In one embodiment, a plurality of termination elements couple the power plane, at or adjacent the peripheral edge thereof, to the ground plane. The termination elements are spaced from each other at substantially regular intervals. In another embodiment, a termination element is a strip or sheet element coupling continuous lengths of the peripheral edge of the power plane to ground plane.
