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.
Claims6
A print head for ink jet printing comprising a gold plated nozzle array and a polymer ink barrier layer on an electronic chip, said head being characterized by having said gold plated nozzle array bonded to said polymer ink barrier layer by a thin layer of tantalum, zirconium, titanium or silicon dioxide.
A print head for ink jet printing comprising a gold plated nozzle array bonded by a layer of tantalum about 200 Angstroms thick to a polymer ink barrier layer which is on an electronic chip.
