    Abstract: A printed circuit board (PCB) is disclosed. The PCB (200) includes a substrate (202) have a top surface (202a) and a bottom surface (202b). A first conductive layer (203) is disposed on the top surface of the substrate. The first conductive layer comprises a first signal net (203a) and a second signal net (203b). An outermost insulating layer (204) is disposed on the top surface of the substrate to cover the substrate and the first conductive layer. The outmost insulating layer comprises an opening (209) to expose a portion of the second signal net. And, a second conductive layer (207) is disposed on the outermost insulating layer and substantially covering at least a portion of the first signal net. The second conductive layer is filled into the opening to electrically connect to the second signal net which is able to provide one of a ground potential and a power potential. The thickness of outermost insulating layer (204) is less than 1 mm.
