The etching is a technology which engraves the high accuracy hole with the strong oxidized liquid.Etching material includes ferric material,copper-base alloy,and stainless steel thickness range is between 0.02mm-2.0mm.the etching uses the solid oxidant that can make the liquids regeneration,which is good for the environment.This technology is widely applied in the integrated circuit,the accurate filter,the precise metal parts,IC panels,LCDand the semiconductor etc |
