What is the metal etching process?

Metal etching processing technology is divided into wet etching and dry etching two kinds, metal etching processing is a series of chemical processes composed. It is mainly through the reaction of chemical potion or physical impact to dissolve the metal material to form the corresponding pattern.

Metal etching process is also known as photochemical etching, the main process is through the surface treatment of the metal material, the surface grease and abnormal surface polishing, etc., after the exposure machine exposure, and then through development, through cooling, through the etching stage, the use of chemical solution contact, remove the protective film of the metal etching area. To dissolve corrosion, form bumps, or hollow out. Etching technology has been fully integrated into aviation, machinery, chemical, semiconductor manufacturing process, electronic information industry and so on.

The advantages of the metal etching process are that the sample production cost is low, almost all the metal is in the etching range, there is no limit on the metal hardness, no scratch, no burr, the design is fast, simple, high efficiency, the process takes 48 hours, the impact of the material thickness on the tolerance of ±10%, the product packaging, and the transfer is extremely convenient. The manufacturing cost of stamping is high, although all metals can be carried out, but in the hardness is too large, too small, easily broken metals are not available, there are scratches on the edge of the cut, and local burrs.
