DROPLET DEPOSITION APPARATUS

摘要

In a method of making an ink jet printhead, corrugations (26) are formed by laser ablation in the bonding surface (24) of a polymer nozzle plate (18). Adhesive (28) is applied to the micro-cavities (26) thus formed and the nozzle plate (18) is pressed against the end surface of the printhead until the surface lands in the nozzle plate abut on the surface of the printhead.
