摘要
A method of fabricating a printed circuit board having a coaxial via is disclosed. The method includes assembling a plurality of layers configured in a stack so that the plurality of layers has a top signal layer and a bottom signal layer; forming a hollow via through the plurality of layers to connect GND layers in the printed circuit board, forming or inserting into the hollow via a conductor coated with non-conductive material, covering the top layer and bottom layer with dielectric and patterned signal layers, covering the top layer and bottom layer with a masking agent, plating the top layer and bottom layer with a conductive material that connects signal traces within via, and removing the masking agent from the top layer and bottom layer.
