Abstract:
Embodiments of the present disclosure relate to the field of electronics and, in particular, to a multi-layer printed circuit board and a method for fabricating the same. The circuit board is able to avoid the problem that signal transmission performance is affected by a plated hole. The multi-layer printed circuit board includes at least two layers of core plates that are adhered, where a circuit mechanical part is disposed on the core plates, a via is also provided on the core plates, and a metal column is embedded in the via, where one end of the metal column is connected to a corresponding position on an antenna feeder circuit mechanical part disposed on the core plate, and the other end is connected to a corresponding position on an antenna feeder circuit mechanical part disposed on an adjacent layer of the core plate. The method is used for fabricating a multi-layer printed circuit board.
