Patent ID: 7645942

Claim:
An apparatus, further comprising: a first circuit having an array of transducers, each transducer having a first electrical contact, the first electrical contact having one of a rectangular, square or rhomboid shape; a print head having a diaphragm arranged adjacent the array of transducers, such that when a transducer receives a signal the transducer causes the diaphragm to deflect and push ink out of the print head; a second circuit having an array of second electrical contacts, each second electrical contact aligned to the electrical contact of the first circuit, the second electrical contact having one of a rectangular, square or rhomboid shape; a standoff structure between the first and second circuits having at least one aperture aligned to the at least one electrical contact of the first and second circuits, the aperture being of an elliptical shape; and a controller electrically connected to the second circuit, the second circuit arranged such that signals from the controller are transmitted to the transducers through the apertures.
