Abstract
A system for plating resonator electrodes or the like by the vapor deposition process employs one or more shutters between the deposition material source and a plating mask. At least one of the shutters has a pair of apertures aligned with different apertures in the plating mark. In one embodiment comprising a two shutter, four position system, the two shutters may be positioned such that either, both or neither of the resonators can be plated. Because each shutter is either ON or OFF, a simple binary analogy for control of the shutters results.
