Abstract: A method of coating spherical components with a coating process in which the spherical components have a surface area includes positioning the spherical components within a containment boundary on a moving member and positioning the moving member within a chamber. The method includes reducing the pressure within the chamber to less than one atmosphere. The method also includes revolving the moving member about a longitudinal axis. The method further includes oscillating the moving member in a direction of the longitudinal axis and commencing the coating process. The oscillating and revolving produce motion of the spherical components within the containment boundary such that an entirety of the surface area of each component is exposed to the coating process.

Abstract: A coupling (30) for the introduction of a bias voltage into a vacuum chamber. The coupling consists of a metallic ball bearing assembly (36), a bearing sleeve or cup (34), and an EMI shielding gasket (42) seated within the bearing sleeve or cup. The ball bearing assembly is fitted within the EMI shielding gasket, about a metallic shaft (32) which, in turn, is coupled to a source of the bias voltage. The bearing sleeve or cup is, in turn, coupled to a rotating component such as a platen, for receiving the bias voltage within the vacuum chamber.
