PURPOSE:To effectively remove burrs without giving damage to components and lowering reliability by using water by a method wherein the burrs of an insulating and sealing material are removed by laser irradiation, and at the same time, a masking is conducted. CONSTITUTION:A bridge 7b is brought into an inconspicuous state by having the narrowing direction of a laser beam by a meniscus lens 8 coincided with the narrow-width direction of the bridge 7b of the pattern punched out by a stainless 7, and the burrs on the part of the bridge 7 can be removed completely by dissolving. As said burr-removing process and the marking process using a laser passing hole 7a can be conducted simultaneously, one process can be reduced. |
