Abstract
In a print head for ink jet printing a nozzle plate with a nozzle array is gold plated. The gold plated nozzle array is bonded to the polymer ink barrier layer on an electronic chip by a thin layer of tantalum, zirconium, titanium or silicon dioxide. The thin layer greatly increases the ability of the surface to bond chemically to the polymer.
