Generally, the term "photochemical etching" refers to the removal of the protective film from the region to be etched after exposure and plate development, and the contact with the chemical solution during etching to achieve the effect of dissolution and corrosion, thereby forming the effect of unevenness or hollowing.
It can be used to manufacture printed embossed plates such as copper plates and zinc plates. It is also widely used in the processing of weight reduction instrument panels, thin-shaped workpieces that are difficult to process on nameplates and conventional processing methods, and has been continuously improved and process equipment. Development can also be used in the processing of precision etching products for electronic sheet parts in the aerospace, machinery and chemical industries. Especially in semiconductor processes, etching is an indispensable technology.
