Latest Patents

Naitoh's latest patents include a method of manufacturing flexible wiring boards. This invention involves providing a reference conductive layer and a first surface conductive layer on both the surface and back face of a first base film. The first base film features a first via hole that penetrates the first surface conductive layer. Following this, a first electroless plating layer and a first conductive material are sequentially grown on the surface of the first base film. The first coating conductive layer, which consists of the electroless plating layer, the conductive material, and the surface conductive layer, is then etched to achieve a reduced thickness. Finally, the coating conductive layer is patterned to form a first wiring layer, allowing for a desired pattern width even when using isotropic etching methods such as wet etching.
