This disclosure describes an improved print cartridge that reduces dimple in the nozzle member and the attendant nozzle trajectory errors. In a preferred embodiment, a nozzle member has a plurality of ink orifices formed therein by suitable processing techniques. A substrate containing a plurality of heating elements and associated ink ejection chambers is affixed to the nozzle member via suitable processing with a suitable adhesive. The heating elements are mounted on a back surface of the nozzle member, each heating element being located proximate to an associated ink ejection chamber and ink orifice, with the back surface of the nozzle member extending over two or more outer edges of the substrate. The nozzle member includes reinforcing features. These features increase the structural integrity of flex circuit in the vicinity of the orifices. The reinforcing features can be of any suitable shape for aiding in stiffening and reducing the long axis curvature of the flex material in the vicinity of the orifices during preprocessing of the flexible circuit. One advantage is that dimple in the nozzle member and the attendant nozzle trajectory errors are reduced.

1. A reinforced circuit comprising:a flexible polymer film having conductive traces formed thereon and defined by a transverse axis and a longitudinal axis; and wherein the film includes a designated area of interest including at least one nozzle with a nozzle camber angle and at least one reinforcing feature located adjacent to the nozzle to provide increased stiffness near the designated area of interest, reduce the longitudinal axis curvature of the flexible polymer film and to control the nozzle camber angle in the designated area of interest for biasing ink drop trajectory.
