Printed circuit board with a conductive connection

摘要

A printed circuit board (500a-d) is disclosed. The printed circuit board comprises a substrate (200) having a top surface (202) and a bottom surface (203). A ground plane (228) is on the bottom surface. A first signal trace (212a) is on the top surface along a first direction. At least two isolated power planes (208, 210) are on the top surface adjacent to opposite sides of the first signal trace, respectively. A conductive connection (216) along a second direction couples to the two power planes, across the first signal trace (212a) without electrically connecting to the signal trace, wherein the first signal trace (212a) doesn't directly pass over any split of the ground plane (228).
