Abstract
A method is described for plating the inner and outer circumferences of a cylindrical dielectric element used in an isolator, and for then assembling the dielectric element with other components to complete the isolator. The dielectric element is first sensitized and activated so that a subsequently applied plating will adhere thereto. The end faces of the dielectric element are then covered with a plating resist, and the element is immersed in a metal plating bath to plate the inner and outer circumferences of the dielectric element. Having been plated, the dielectric element and other components of the isolator are assembled within a hollow connector and joined thereto using a solder sheath.
