Abstract
A printed circuit board includes a substrate having a top surface and a bottom surface. First non-ground nets and a ground net are disposed within a specific region on the top surface. A second non-ground net and a split ground net are disposed on the bottom surface. The second non-ground net is electrically connected to one of the first non-ground nets through a first via hole in the substrate. The second non-ground net is isolated from the split ground net by a gap. An outermost insulating layer on the bottom surface of the substrate covers the second non-ground net and the split ground net. A conductive layer is disposed on the outermost insulating layer corresponding to the specific region of the substrate in which the first non-ground nets and the ground net are arranged, such that the conductive layer overlaps with the first non-ground nets.
