What process is usually used for metal etching?

Metal etching is a technique to remove materials by chemical reaction or physical impact. metal etching technology can be divided into wet metal etching and dry metal etching. Metal etching principle. technological process. The metal etching process removes the film layer not covered by the resist, so as to obtain the same pattern on the film as that on the resist film.

What is metal etching process
Metal etching is a technology to remove materials by chemical reaction or physical impact. Metal etching technology can be divided into wet metal etching and dry metal etching.

It can be used to manufacture concave and convex printing plates such as copper plate and zinc plate at the earliest, and is also widely used to process weight reduction instrument panels, nameplates and thin workpieces that are difficult to process by traditional processing methods; Through continuous improvement and development of process equipment, it can also be used for the processing of precision metal etching products of electronic sheet parts in the aviation, mechanical and chemical industries. Especially in the semiconductor process, metal etching is an indispensable technology.

Metal etching principle
The commonly referred metal etching is also called photochemical metal etching, which refers to the removal of the protective film of the area to be etched after exposure, plate making and development, and the contact with the chemical solution during metal etching to achieve the effect of dissolution and corrosion, forming concave convex or hollow molding.

Metal etching process commonly used
Exposure method: according to the figure, the project will issue the size of material preparation - material preparation - material cleaning - drying → film or coating → drying → exposure → development → drying - metal etching → film removal → completion.
Screen printing method: material opening → plate cleaning (stainless steel and other metal materials) → screen printing → metal etching → film removal → completion.
metal etching premium version: use inkjet printing technology to print the anti-corrosion ink to the material surface → then solidify it (generally using light curing or heat curing) → obtain the anti-corrosion layer → chemical or electric corrosion.
