Title: Innovations of Masakazu Mitsuhashi in Surface-Treated Copper Foil
Introduction
Masakazu Mitsuhashi is a prominent inventor based in Ageo, Japan, known for his significant contributions to the field of materials science, particularly in the development of surface-treated copper foils. With a total of seven patents to his name, Mitsuhashi has focused on enhancing the performance and durability of copper foils used in printed wiring boards.
Latest Patents
Mitsuhashi's latest patents revolve around methods of producing surface-treated copper foils that exhibit exceptional resistance to hydrochloric acid degradation. One of his notable inventions aims to achieve a percent loss of peel strength of 10% or less when subjected to hydrochloric acid, specifically for copper patterns with a line width of 0.2 mm. This is accomplished by maximizing the effectiveness of silane coupling agents in brass-plated anti-corrosive copper foils. Additionally, he has developed methods to impart excellent moisture resistance, heat resistance, and long-term storage stability to these foils. The treatment process includes forming a zinc-copper plating layer, an electrodeposited chromate layer, and a silane-coupling-agent-adsorbed layer, followed by a drying process that elevates the temperature of the copper foil to between 105°C and 200°C.
