ABSTRACT:
A method of manufacturing a printed wiring board comprises providing a substrate and forming a printed circuit having a ground circuit on the substrate. An insulating layer is formed on the substrate over the printed circuit and consists of two successively formed insulating layers having concentric circular apertures defining an opening above the ground circuit. The opening has a circular, stepped shape effective to facilitate the subsequent formation of an electromagnetic wave shielding layer. An electromagnetic wave shielding layer is formed by silk screening a conductive paste on the substrate over the insulating layer and through the opening and over the ground circuit.
