Abstract:
1. A method of attaching one or more printhead integrated circuits to an ink supply manifold, said method comprising the steps of: (a) providing a laminated film having a plurality of ink supply holes defined therein, said laminated film comprising a central polymeric film sandwiched between first and second adhesive layers, wherein a first melt temperature of said first adhesive layer is at least 10° C. less than a second melt temperature of said second adhesive layer; (b) aligning said film with said ink supply manifold such that each ink supply hole is aligned with a respective ink outlet defined in a manifold bonding surface of said ink supply manifold; (b) bonding said first adhesive layer to said manifold bonding surface by applying heat and pressure to an opposite side of said film; (c) aligning said one or more printhead integrated circuits with said film such that each ink supply hole is aligned with an ink inlet defined in a printhead bonding surface of each printhead integrated circuit; and (d) bonding said one or more printhead integrated circuits to said second adhesive layer.
