Abstract
An ink jet tip assembly in which the individual jets are comprised of a piezoelectric cylinder having a longitudinally through bore, a glass ink nozzle disposed in the cylinder bore and a low melting temperature alloy interposed between the bore and the nozzle for anchoring the nozzle to the piezoelectric cylinder. The method of assembly for the individual jet tip assemblies comprises inserting the glass ink nozzle into the cylinder bore which contains the anchoring alloy in a molten form. A method of checking for flaws in the cylinder comprises fluxing the cylinder bore for allowing flux to pass through any cylinder pinholes or cracks. Upon introducing solder for coating the interior cylinder wall, some solder will appear as shining spots or areas on the cylinder exterior wall.
