Patterned conductive array and self leveling epoxy

An ink jet print head, comprising:

• a diaphragm comprising a plurality of openings therethrough;
• a body plate attached to the diaphragm with a diaphragm attach material;
• a plurality of piezoelectric elements attached to the diaphragm;
• an interstitial layer encapsulating the plurality of piezoelectric elements;
• a plurality of conductive elements;
• a plurality of conductive particles interposed between each conductive element and each piezoelectric element, wherein the plurality of conductive particles are dispersed within the interstitial layer, are electrically isolated from each other, and electrically couple the plurality of piezoelectric elements to the plurality of conductive elements.
