Title: Innovations of Yoshifumi Shinogi
Introduction
Yoshifumi Shinogi is a notable inventor based in Osaka, Japan. He has made significant contributions to the field of circuit board manufacturing, holding 2 patents that showcase his innovative approaches.
Latest Patents
One of his latest patents is a producing method of a flexible wired circuit board. This method prevents the formation of a gap between an elongate substrate and a stiffener sheet bonded to it, thereby avoiding contamination of the flexible wired circuit board. The process involves forming a conductive pattern on the surface of the elongate substrate using a semi-additive process with electrolysis plating, followed by annealing the substrate in its wound-up state. A stiffener sheet, narrower than the elongate substrate, is then bonded to the back side. The oxidized film on the conductive pattern is removed, and a solder resist is formed, which prevents the strip of the stiffener sheet from detaching and keeps etching or developing solutions from entering any gaps.
Another significant patent is a method of manufacturing a double-sided circuit board. This method utilizes a board material with a first electric conductor layer and a first electrically insulating layer. The process includes making conduction holes that penetrate the insulating layer, forming an electrically conductive thin-film layer, and creating a second insulating layer. The method further involves electroplating to form electric conductor wiring and applying a chemical-resistant film, followed by the removal of the insulating layer and film.
