Abstract:
A printed circuit board comprising:a first conductive layer forming a first power supply plane; a second conductive layer forming a second power supply plane; a first dielectric layer adjacent to and separating the first and second conductive layers; a second dielectric layer adjacent to said second conductive layer; a third conductive layer forming a third power supply plane, wherein the third conductive layer is adjacent to said second dielectric layer; a fourth conductive layer forming a fourth power supply plane; a third dielectric layer adjacent to and separating the third and fourth conductive layers; wherein at least one of the first, second, third, or fourth conductive layers includes one or more uniform patterns, wherein each of the one or more uniform patterns includes a plurality of slots, wherein the slots comprise a removed portion of conductive material, and wherein the slots are arranged such that a bridge of conductive material exists between them.
