1. A method for making a visually transparent radio frequency interference shield comprising the steps of:

  • providing a photo-sensitive, thick film composition on a substrate;

    exposing the photo-sensitive composition to photo radiation to define a pattern of interconnected elements forming a grid of crossed and electrically connected conductive lines in two dimensions for the radio frequency interference shield;

    developing the exposed photo-sensitive composition in solution to remove the thick film material in areas not exposed to photo radiation; and

    firing the developed thick film composition, thereby forming an enhanced conductivity thick film on the optically transparent substrate.
