Our company introduced the advanced etching equipment . the etching is a technologywhich engraves the high accuracy hole with the strong oxidized liquid.Etching material includes ferric material , copper-base alloy, and stainless steelthickness ranges is between 0.02mm-2.0mm. the precision is about 0.005mm. theetching aperture may achieve 0.08mm or smaller ,and the pitch of holes can achieve0.2mm the etching uses the solid oxidant that can make the liquids regeneration,which is good for the environment protection. This technology is widely applied in the integrated circuit, the accurate filter,the precise metal parts, IC panels ,LCD and the semiconductor light covers, thestrainer, the data plate and so on.
