Title: Eiji Sakata: Innovator in High-Frequency Substrates and Screen Printing Technology
Introduction
Eiji Sakata is a notable inventor based in Fukuoka-ken, Japan. He has made significant contributions to the fields of high-frequency substrates and screen printing technology. With a total of four patents to his name, Sakata's work showcases his innovative spirit and technical expertise.
Latest Patents
One of Sakata's latest patents is for a high-frequency substrate and its production method. This substrate is constructed from a base member and a conductor adhered to it. The base member is made of a fluoropolymer that has a conductor-affinitive monomer graft-polymerized at a grafting percentage of 1% or less by weight. The process involves forming reactive sites on a fluoropolymer film under an oxygen-free atmosphere by irradiating it with an electron beam. The film is then introduced into a solution of the conductor-affinitive monomer to facilitate graft-polymerization, resulting in a substrate with superior adhesion force to the conductor.
Another significant patent by Sakata is for a squeegee designed for screen printing. This squeegee comprises a body formed from a metal sheet, featuring a squeegeeing face and a convexly curved pressing edge. When oriented for squeegeeing, the center of curvature of the pressing edge extends horizontally, enhancing its functionality in the printing process.
