Title: Kiyotake Fukawa: Innovator in Printed-Circuit Board Technology
Introduction
Kiyotake Fukawa is a notable inventor based in Hiratsuka, Japan. He has made significant contributions to the field of printed-circuit board technology, holding a total of 3 patents. His innovative processes have improved the efficiency and effectiveness of printed-circuit board preparation.
Latest Patents
Fukawa's latest patents include a process for preparing a printed-circuit board that involves several key steps. The process begins with coating a photosensitive electrodeposition coating composition onto a printed-circuit copper-clad, laminated base plate to form a photosensitive resist film. Following this, a pattern mask is applied to the resist film, which is then exposed to active light, developed, and etched. Additionally, the copper-clad base plate undergoes a corrosion-preventing treatment using a nitrogen-containing heterocyclic compound as a corrosion inhibitor before the coating step. Another patent discloses an improved process that includes dipping the photosensitive resist film into an aqueous solution and applying a voltage to carry out electroendosmosis, which reduces the tendency of the resist film to stick to the pattern mask.
