Zusammenfassung:A method of attaching one or more printhead integrated circuits to an ink supply manifold. The method comprises the steps of: (a) providing a laminated film having a plurality of ink supply holes defined therein, the laminated film comprising a central polymeric film sandwiched between first and second adhesive layers, wherein a first melt temperature of the first adhesive layer is at least 20° C. less than a second melt temperature of the second adhesive layer; (b) aligning the film with the ink supply manifold such that each ink supply hole is aligned with a respective ink outlet defined in a manifold bonding surface of the ink supply manifold; (b) bonding the first adhesive layer to the manifold bonding surface by applying heat and pressure to an opposite side of the film; (c) aligning the printhead integrated circuits with the 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 the printhead integrated circuits to the second adhesive layer.
