Title: Satoshi Yoshiura: Innovator in Organic Insulators and Wiring Boards

Introduction

Satoshi Yoshiura is a prominent inventor based in Kirishima, Japan. He has made significant contributions to the field of materials science, particularly in the development of organic insulators and wiring boards. With a total of 4 patents to his name, Yoshiura continues to push the boundaries of innovation in his industry.

Latest Patents

Yoshiura's latest patents include an organic insulator and a wiring board. The organic insulator is produced from a cured resin product containing a cyclic olefin copolymer as its main component. This innovative material has a cumulative luminescence amount measured by the chemiluminescence measurement method of 4×10cpm or less. The glass transition temperature of the cured product ranges from 134° C. to 140° C, with a cumulative luminescence amount between 8.2×10cpm and 3.2×10cpm. The wiring board he developed features an insulation layer and an electrical conductor layer, where the insulation layer utilizes the aforementioned organic insulator.

The wiring board itself comprises an insulating layer made of organic resin with inorganic particles. It includes a first metal layer on one surface and a second metal layer on the opposite surface. The insulating layer has a thickness ranging from 75-1000 μm and a storage modulus between 4 GPa and 7 GPa. The first metal layer has a thickness of 1.5-10 μm and a coverage of 5%-25%, while the second metal layer has a thickness of either 3-10 μm or 25-100 μm, with a coverage of 85% or more. Notably, the surface part of the insulating layer on the first metal layer side has a higher ratio of organic resin compared to the surface part on the second metal layer side.
