形成される。(Prior Art) A solder resist is formed in order to prevent solder from sticking to unnecessary places on a circuit and to protect a conductor pattern when an electronic component is mounted on a printed wiring board. . The pattern of this solder resist is applied with liquid photosensitive resin on the circuit surface, or a photosensitive resin film is attached on the circuit surface, and ultraviolet rays are exposed (exposed) in a predetermined pattern to dissolve the photosensitive resin in unnecessary parts. It is formed by removing (developing).
