 Chemical etching is a superior method to make light shielding plate used in optical applications, such as LED. The process creates precise openings to your exact specifications. light shielding plate are created without burrs. Burrs can affect the size and shape of the opening and flatness of a part. Chemical etching will not add stress to the metal which can affect the flatness of the part. In addition, when the undesired material is dissolved instead of stamping or machined away, there is no work hardening to the edges which could affect the performance of the light shielding plate.
