Zusammenfassung:	An ink jet print head including a plurality of standoff layer supports in an interstitial region between adjacent piezoelectric elements, and method of formation. The plurality of standoff layer supports can be formed from the same layer(s) as the piezoelectric elements, or from a dielectric layer such as a polymer. The standoff layer supports increase an area to which a standoff layer can be attached, thereby forming a more secure attachment of a circuit layer such as a flex circuit or a printed circuit board to a jet stack subassembly.
