ABSTRACT:
A coating fixture for holding and masking workpieces during a parylene batch coating process. A rigid frame and two face plates form an enclosure. The face plates have a plurality of holes, and the workpieces are located within the enclosure, so that they are aligned with the holes. In preferred embodiments, a separator plate located within the enclosure divides it into two article-receiving compartments, and gaskets are provided for sealably engaging the face plates to the frame and to the workpieces in each compartment. Vaporous coating material enters the face plate holes and coats only portions of the workpieces.
