Photoetching makes cleaner, more precise products
Tech-Etch uses photoetching to make a variety of equipment parts with sharper precision than traditionally machined parts. They can make custom light-gauge parts without burred edges in intricate patterns and with precise tolerances. They also make photoetched screens with tapered or straight holes, custom board-level shielding and flexible circuits. The flexible circuits use adhesive or nonadhesive materials. They are made out of materials including beryllium copper, stainless steel, aluminum alloys, titanium, tungsten, nitinol, molybdenum, brass and spring steels, and even polyimide film. They are usually 0.0005 to 0.0300 inch thick, and laser machining is available for parts from 0.030 to 0.125 inch. Laser machining is also available for polyimide laminate drilling and ablating, and a number of other finishing processes are available in-house.
