1. A method for forming an inkjet printhead assembly comprising the steps of:

  • providing a flexible insulating tape having a first set of conductive traces formed thereon, for conducting energization signals, and having securing traces formed thereon, portions of said first set of conductive traces and portions of said securing traces located proximate to an opening formed in said flexible insulating tape;

    positioning a nozzle plate, having nozzles formed therein, within said opening;

    bonding said portions of said securing traces to said nozzle plate;

    aligning a substrate with said nozzle plate, said substrate having a plurality of ink ejection means formed thereon, each ink ejection means being paired with an associated one of said nozzles formed in said nozzle plate; and

    bonding said portions of said first set of conductive traces to associated electrodes formed on said substrate.
