Abstract

One of the problems in manufacturing aperture plates used in ink jet printing is the yield. If, in the formation of a long array of apertures, one of the apertures is not properly formed, the entire array has to be discarded. Employing a modular technique to construct this array of nozzles overcomes this difficulty. A bilayer structure of nickel on nickel may be attained by using a preshaped undersized thermal settable adhesive film which is placed between stainless and gold pieces. Edges of metal protrude to prevent lateral oozing of the plastic. A laser beam cleans the apertures to eliminate any lateral flow and clogging of the adhesive produced therein.
