An apparatus including a base, a linkage extending along a second axis and pivotally connected to the base for pivotal movement about a first axis perpendicular to the second axis, a leg having a first end pivotally connected to the linkage for pivotal movement about the second axis, and a frame secured to a second end of the leg. A stand extends from the base, and a first slide is secured to a distal end of the stand for pivotal movement with respect to the distal end of the stand. A first guide is supported by the first slide for movement with respect to the first slide, and a second slide is secured to an end of the first guide. A second guide is pivotally connected to the frame and supported by the second slide for movement with respect to the second slide. The frame can be used to support a plating mask and is movable along a surface of an imaginary sphere having a center located at the intersection of the first and the second axes.
