Title: Kazuo Otani: Innovator in Circuit Board Technology
Introduction
Kazuo Otani is a prominent inventor based in Osaka, Japan. He has made significant contributions to the field of circuit board technology, holding 2 patents that showcase his innovative approach to electronic components.
Latest Patents
His latest patents include a multilayer circuit board and a manufacturing method thereof. This invention involves forming holes with the same diameter as via holes in predetermined positions when creating wiring patterns on releasable carriers. The carriers with the wiring patterns are bonded onto an insulating material. A laser beam is then irradiated from the side of the carrier using the holes in the wiring pattern as a laser mask to form via holes in the insulating material. The via holes and the holes in the carrier are subsequently filled with a conductive paste. This method ensures that lands in the conductor layers are precisely positioned relative to the via holes, resulting in a multilayer circuit board with lower electrical connection resistance and improved performance.
Another notable patent is the method for manufacturing a component built-in module. This module includes a first wiring pattern, an electronic component mounted on it, a second wiring pattern, and an electrical insulating sheet that houses the electronic component. A via conductor is formed in a via hole that penetrates through the electrical insulating sheet, connecting the first and second wiring patterns electrically. This design enhances the reliability of electrical connections within the module.
