Part design geometry for stenciling epoxies through orifices in film adhesive

Abstract

A method of manufacturing a print head includes forming a jet stack, the jet stack including a nozzle plate having an array of nozzles, attaching an array of transducers to the jet stack, wherein the array of transducers has a transducer corresponding to each nozzle, adhering an adhesive layer to the array of transducers, forming opening in the adhesive layer, each opening adjacent a transducer in the array of transducers, partially removing the adhesive layer in regions adjacent the openings, such that the adhesive layer is less thick in the regions adjacent the openings than in other regions, and filling the openings with a conductive material, such that when the conductive material is applied, any air in the openings moves into the regions of the adhesive layer with less thickness adjacent the openings.
