Abstract:
A component carrier includes an electrically insulating layer structure with a first main surface and a second main surface, a through hole extends through the electrically insulating layer structure between the first main surface and the second main surface. The through hole has a first tapering portion extending from the first main surface and a second tapering portion extending from the second main surface. The through hole is delimited by a first plating structure on at least part of the sidewalls of the electrically insulating layer structure and a second plating structure formed separately from and arranged on the first plating structure. The second plating structure includes an electrically conductive bridge structure connecting the opposing sidewalls.
