Abstract
Abstract An electronic device includes a flat flexible dielectric substrate which is less than 0.050 inch thick and has a generally round hole of a given diameter. A ductile conductive film is deposited on the substrate in an area at least about the hole. A generally round terminal pin is inserted into the hole in the substrate in contact with the conductive film. The pin has a given diameter greater than that of the hole. The difference between the diameter of the pin and the diameter of the hole is on the order of 5% to 50% of the diameter of the hole.
