A major problem in the fabrication of a multinozzle ink jet assembly is the ability to bond a nozzle array to a support plate with a corrosion resistant material. All epoxies degrade with time and solder glasses are readily attacked by alkaline inks. A typical field assist bond between a metal or silicon and PYREX (Trademark of Corning Glass Works) can be made at 300 degrees C and 500 volts, and temperatures as low as 200 degrees C are possible.
