IMPROVED APERTURE PLATE AND METHODS FOR ITS CONSTRUCTION AND USE

摘要

A method for performing an aperture plate (10) comprises providing a mandrel (26) that is constructed of a mandrel body (28) having a conductive surface (30) and a plurality of non-conductive islands (32) disposed on the conductive surface. The mandrel is placed within a solution containing a material that is to be deposited onto the mandrel. Electrical current is applied to the mandrel to form an aperture plate on the mandrel, with the apertures having an exit angle that is in the range from about 30~ to about 60~.
