Patent ID: 8585185

Claim:
An ink jet print head, comprising: a piezoelectric element array comprising a plurality of piezoelectric elements spaced apart from each other; a first flexible circuit (first flex circuit) comprising a first trace metallization layer, wherein: the first trace metallization layer comprises a plurality of first traces and a plurality of first embossed pads; the plurality of first traces are continuous with the plurality of first embossed pads in the first trace metallization layer; and each first embossed pad is electrically coupled to one of the piezoelectric elements; a second flex circuit comprising a second trace metallization layer, wherein: the second trace metallization layer comprises a plurality of second traces and a plurality of second embossed pads; the plurality of second traces are continuous with the plurality of second embossed pads in the second trace metallization layer; and each second embossed pad is electrically coupled to one of the piezoelectric elements, wherein each piezoelectric element is configured to be individually addressable through one of the plurality of first embossed pads and the plurality of second embossed pads, and wherein at least a portion of the first flex circuit is interposed between the second flex circuit and the piezoelectric element array.
