Title:
LAMINATED ELECTROFORMED APERTURE PLATE
Document Type and Number:
WIPO Patent Application WO2003028895
Kind Code:
A3
Abstract:
An aperture plate (10) comprises a plate body (12) having a top surface (16), a bottom surface (18), and tapered walls that form a plurality of apertures (14) that taper from the bottom surface (18) to the top surface (16) wherein the plate body (12) comprises a base material (34) and a corrosion resistive material plating at least the tapered walls. The aperture plate (10) can be produced by electroplating a mandrel (26) wherein the mandrel (26) is placed within a solution containing a material that is to be deposited onto the mandrel (26). Electric current is applied to the mandrel (26) to form the aperture plate (10) on the mandrel (26). The process can be repeated so as to deposit a second layer (36), such as a corrosion resistive material, over a base layer material (34). In such fashion, a laminated electroformed aperture plate can be produced.
