Abstract:
1. A method of forming an optical filament circuit pattern having planar and non-planar portions on or in the vicinity of a surface of a dielectric substrate, the method comprising: scribing at a speed between 110 inches/minute and 190 inches/minute a pre-selected length of a continuous optically conductive filament in a plane parallel to the substrate surface and on or in a vicinity of the substrate surface to form a planar portion of the circuit pattern from the scribed length of filament; forming a non-planar portion of the circuit pattern by controllably moving the filament in planar and non-planar directions and placing a next pre-selected length of the continuous filament that is contiguous to the immediately preceding scribed length so that the next pre-selected length of filament traverses but does not adhere to a pre-selected surface or feature forming part of the substrate surface; and scribing at a speed between 110 inches/minute and 190 inches/minute in a plane parallel to the substrate surface, and on or in a vicinity of the substrate surface a next pre-selected length of the continuous filament that is contiguous to the length of the filament that forms the non-planar portion of the filament circuit to form another planar portion of the circuit, wherein a bond strength between the optical filament and the substrate is achieved of between 7 grams and 14 grams.
