SRR Tech specializes in the design and production of board level Shields and Cans for PCB. The photoetching process allows the fabrication of parts with complex shapes and features that are impossible to duplicate by other methods without expensive tooling.Board level shielding is typically etched from .007" - .020" brass, nickel silver, copper or cold rolled steel. Board level shielding can also be manufactured out of beryllium copper, if spring qualities are desired. The standard finish is tin plate. Other finishes are available.
