Static electricity suppressor with patterned coating and method of making

摘要

A static electricity suppressor includes a base insulating sheet having conductive patterns coated on its two surfaces, and ion emitters in the form of pointed wires passing through the sheet, the ionizing points of the emitter extending beyond one surface of the base and being spaced from the pattern thereof, which is grounded. The opposite ends of the emitters are coupled to the pattern on the second surface of the base, capacitively or directly, which second surface pattern is connected to electrical source(s). A method of making a static electricity suppressor comprises providing electrically conductive pattern coatings on opposite surfaces of a base sheet of insulating material and causing emitters, which include ionizing points, to extend transversely through the base sheet with the ionizing points beyond the adjacent base sheet surface and spaced from the pattern on that surface, the opposite ends of the emitters engaging the pattern on the opposite surface, which is in registry with the removed portion of the coating on the first surface.
