Metal etching processing, firstly, the designed pattern will be made into film film, and then it will be pasted on the metal surface, through the exposure and development process, so that the pattern is transferred to the metal. Subsequently, the metal parts are immersed in an etching solution containing an etchant such as ferric chloride, and the unprotected metal parts react with the etchant to be corroded away, forming the desired pattern or shape. Finally, the metal parts are cleaned to remove the residual etching solution and photographic ink to complete the metal etching process. This method is suitable for making fine and complex patterns, and is widely used in electronics, medical devices and other fields.
