High density electrical interconnect using limited density flex circuits

An ink jet print head, comprising:

• a plurality of pads of a first flexible circuit (flex circuit) electrically coupled to a first plurality of piezoelectric elements of a piezoelectric element array;
• and
• a plurality of pads of a second flex circuit electrically coupled to a second plurality of piezoelectric elements of the piezoelectric element array,
• wherein the first plurality of piezoelectric elements is different from the second plurality of piezoelectric elements and each piezoelectric element of the first and second plurality of piezoelectric elements is configured to be individually addressable through one of the first plurality of pads and the second plurality of pads.

A printer, comprising:

• a plurality of pads of a first flexible circuit (flex circuit) electrically coupled to a first plurality of piezoelectric elements of a piezoelectric element array;
• a plurality of pads of a second flex circuit electrically coupled to a second plurality of piezoelectric elements of the piezoelectric element array,
• wherein the first plurality of piezoelectric elements is different from the second plurality of piezoelectric elements and each piezoelectric element of the first and second plurality of piezoelectric elements is configured to be individually addressable through one of the first plurality of pads and the second plurality of pads;
• a manifold physically attached to the first and second flex circuits;
• and
• an ink reservoir formed by a surface of the manifold.
