1. Confirmation raw—Surface treatment (clean from oil, dust) 2. Drying—Coating with photosensitive ink 3.Drying—Explored prototypes in the stencils by film 4.Drying—Chemical etching by liquid medicine

First of all, you should know the main production technologies of photochemical etching and stamp for metal components. Photochemical etching also called wet etching, the main process is to etch metal raw materials with chemical solutions to get the desired metal shapes. Stamping is to make the metal plates deformed by high pressure with tools

Most of shielding blanks for phones are used by stainless steel or nickel silver materials with 0.2mm thickness, to ensure the shielding effect and do tin or nickel plated, the flatness is controlled within 0.05mm strictly, it is a high precision component. No burrs, high precision, tight tolerance, and easy to make the prototype, photo
