Title: Innovations of Takeshi Yamato in Circuit Board Manufacturing

Introduction

Takeshi Yamato is a notable inventor based in Ibaraki, Japan. He has made significant contributions to the field of circuit board manufacturing, holding a total of 3 patents. His work focuses on innovative methods that enhance the efficiency and quality of printed circuit boards.

Latest Patents

One of his latest patents is a method for manufacturing printed circuit boards. This method involves preparing an insulating layer made of an insulator film, followed by the formation of a thin metal film and a thin copper film on the insulating layer. The process includes laminating the thin copper film with a dry film, exposing and developing it to create a plating resist with patterns opposite to the conductor patterns. Subsequently, conductor patterns made of copper are formed through electrolytic plating. The plating resist is then removed, and the thin copper film undergoes thermal treatment at a specified temperature. Finally, chemical etching is used to remove the thin copper film and thin metal film, except for the portions under the conductor patterns.

Another significant patent by Yamato is the producing method of a flexible wired circuit board. This method aims to prevent the formation of gaps between an elongate substrate and a stiffener sheet bonded to it. The process involves forming a conductive pattern on the elongate substrate using a semi-additive process and bonding a stiffener sheet to the back side of the substrate. This innovative approach ensures that etching or developing solutions do not contaminate the flexible wired circuit board.
