Title: Mikio Nishihara: Innovator in Circuit Board Technology
Introduction
Mikio Nishihara is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of circuit board technology, holding a total of 11 patents. His work focuses on enhancing the efficiency and cost-effectiveness of thin film multi-layered circuit boards.
Latest Patents
Nishihara's latest patents include a high-density thin film circuit board and a method of production thereof. This innovation aims to provide electrical conduction between the front and back surfaces of a thin film multi-layered circuit board, such as a Multi-Chip Module (MCM), at a low cost without the need for a simultaneous firing process for ceramics. The design features at least one thin film circuit layer on a substrate's first surface, with a conductor layer in the lowermost layer that is in contact with the substrate. Holes are formed through the substrate to allow electrical conduction, with diameters that gradually enlarge from the first surface to the second surface.
Another notable patent is a circuit arrangement for a multilayer printed circuit board. This arrangement includes a first circuit layer formed on a substrate, which comprises a dielectric layer with a circuit pattern. A second circuit layer is formed on top of the first, featuring a dielectric layer with its own circuit pattern. The first circuit pattern includes conductive segments with only an X-directional component, while the second includes segments with only a Y-directional component. Electric connections between these segments are established through vias provided in the second layer.
