Abstract
The invention provides a method for making an electrical circuit device as well as a resulting device itself. The method includes the steps of forming a base or substrate of conductive metal and then securing an electrically conductive masking element to the substrate. The resulting product is coated with a layer of fusible particles of a dielectric or resistive material that is repelled by the surface of the masking element. The coated product is then heated to fuse the particles and provide a hard dielectric or resistive layer over surface portions of the base. The masking element provides an exposed conductive path to the base metal or substrate. A section of conductive metal foil may be bonded to the masking element to provide a continuous conductive bus on the substrate.
