MANUFACTURING METHOD OF SERRATION FOR TERMINAL

摘要

The present invention relates to a serration processing method for a terminal, capable of reducing manufacturing costs. The method comprises: a degreasing step of removing contamination attached on the surface of a material to be processed; a laminating step of forming a film received on the surface of the material; an exposing step of irradiating light on the material having the film received thereon to expose a part of the material to the light; a developing step of spraying a development solution on the material to position the development solution in a part which is not exposed to the light; an etching step of spraying an etching solution on the material to etch the surface of the material and form a serration; and a pilling step of removing the development solution which remains on the material after completing the etching process.
