Title: Masakazu Hatori: Innovator in Circuit Board Technology
Introduction
Masakazu Hatori is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of circuit board technology, holding a total of 2 patents. His work focuses on enhancing the performance and reliability of circuit boards, particularly in high-heat applications.
Latest Patents
Hatori's latest patents include an innovative aluminum nitride circuit board. This circuit board is designed to serve as a carrier for components that emit a large volume of heat. The substrate of this circuit board is a sintered aluminum nitride substrate, which features a basal part and projections that rise from it. These projections provide a surface for applying a metallizing composition. The metallized layer is formed on the upper side of the projection, preventing sagging down the lateral side of the basal part. This design significantly improves the circuit board's voltage withstanding property. Additionally, the curved surfaces formed in the rising part of the projection enhance the yield during production and reduce the risk of cracks during service.
Another notable invention by Hatori is a substrate structure that comprises a ceramic tile and a conductor layer made of copper or copper alloy. This conductor layer is directly joined to the surface of the ceramic tile, with an outgoing terminal connected to it. The unique aspect of this substrate structure is that the part of the conductor layer to which the outgoing terminal is joined is raised from the ceramic tile, bridging an empty space.
