Tech-Etch photo etches polyester film to make flat parts for many applications. Typical photo etched applications include non-conductive washers, dielectrics, diaphragms, gaskets, washers, discs, spacers, seals, and caps, plus insulation layers and liners. Parts can be etched with intricate features in addition to a partial etch to form relieved shapes on the polyester film's surface.
