ABSTRACT:
A glass nozzle array for use in an orifice plate or charge plate in an ink jet printer is formed with a plurality of glass tubes aligned parallel to one another and cemented in epoxy between two parallel glass plates. This glass nozzle array is formed by aligning a plurality of very small inside and outside diameter glass tubes on spaced supports of oriented silicon which are etched to form the grooves to properly align the glass tubes, a plate of glass is then positioned below the tubes and an epoxy resin poured through the tubes onto the glass and a second plate of glass is placed above the tubes to form a sandwich which upon curing is sliced orthagonal to the tubes to produce wafer thin glass nozzle arrays with glass support pieces for rigidity. Ths assembly is then adhered to a rigid backing plate to form either an orifice plate or a charge plate for an ink jet printer.
