    摘要: The present invention relates to computer hardware design and in particular to a printed circuit board comprising wiring dedicated to supply electric board components such as integrated circuits with at least three different reference planes. In order to provide a printed circuit board having an improved signal return path for basically all relevant signal layers at transitions between card, connector, module and chip while still holding the cross-section structure simple, it is proposed to establish a layer structure whereina) a split voltage plane is located adjacent to one side of one of said reference planes and comprises conducting portions for all of said at least three different voltage levels in respective plane parts, andb) a signal layer being located adjacent to said reference planes.

    摘要: A circuit board and a method for fabricating a circuit board are provided. The circuit board includes a dielectric core comprising a first surface and a second surface and a conductive layer comprising a first surface and a second surface. The first surface of the conductive layer is coupled to the second surface of the dielectric core. A first region of the second surface of the conductive layer is smooth and a second region of the second surface of the conductive layer is rough. The first region of the second surface of the conductive layer is operable to support high speed signaling and the second region of the second surface of the conductive layer is operable to support non-high speed signaling.
