What is Metal Etching?

Metal etching is a technique for removing materials using chemical reaction or physical impact. Metal etching technology can be divided into two types: wet etching and dry etching. Metal etching is composed of a series of complex chemical processes, and different corrosives have different corrosion properties and strengths for different metal materials.

Metal etching is usually referred to as photochemical etching, which refers to the removal of the protective film of the metal etching area after exposure, plate making and development, and contact with chemical solutions during metal etching to achieve the effect of dissolving and corroding, forming bumps or hollows The effect of molding. It was first used to manufacture copper plate, zinc plate and other printing concave and convex plates, and also widely used in the processing of weight reduction instrument panels, nameplates and thin workpieces that are difficult to process by traditional processing methods; after continuous improvement and process equipment Development, it can also be used in the processing of precision metal etching products of electronic thin parts in the aviation, machinery, and chemical industries. Especially in the semiconductor manufacturing process, metal etching is an indispensable technology.
