Latest Patents
Yutaka Yoshikawa's latest patents include a water-based solder resist composition and an innovative process for preparing a printed circuit board. The latter patent discloses an improved method that involves successive steps of electrodeposition coating of a photosensitive resin on a printed circuit base plate. This process forms a photosensitive resist film, which is then exposed to light through a pattern mask, developed, and etched. A key improvement in this method is the step of dipping the photosensitive resist film into an aqueous solution, applying a voltage to carry out electroendosmosis. This technique reduces the tendency of the photosensitive resist film to stick to the pattern mask, thereby enhancing the overall manufacturing process.
