Abstract:
A method for contacting a metallic contact pad embedded in a printed circuit board layer sequence, comprising the steps of producing a first hole matrix having a plurality of holes in a surface of the printed circuit board layer sequence in order to partly expose the metallic contact pad, of applying a metal layer in order to at least partly fill the holes of the first hole matrix, of producing a second hole matrix having a plurality of holes in the surface of the printed circuit board layer sequence in order to partly expose the metallic contact pad, wherein the holes of the second hole matrix are arranged in a manner offset relative to the holes of the first hole matrix, and of applying a metal layer in order to at least partly fill the holes of the second hole matrix, and a correspondingly produced printed circuit board.
