A method according to claim 2 wherein the MST device has an array of inlet apertures in the attachment face connected to a plurality of first fluid conduits, the attachment face has an array of outlet apertures connected to a plurality of second fluid conduits and the laminated film has an array of openings for establishing fluid communication between corresponding apertures in the inlet and outlet arrays.
4. A method according to claim 2 wherein the opening in the laminated film is laser drilled.
5. A method according to claim 4 wherein the laminated film is drilled with a Uw laser so as to not cure the thermosetting adhesive layers immediately adjacent the opening.
6. A method according to claim 5 wherein the central web is a polyimide film.
7. A method according to claim 6 wherein the polyimide film is more than 25 microns thick.

14. A method according to claim 2 wherein the laminated film is sandwiched between two protective liners, the liner on the support member side of the laminated film being removed after laser drilling the opening but before the attachment of the support structure and the protective liner on the MST device side is removed prior to attaching the MST device.
15. A method according to claim 14 wherein the protective liners are PET.
16. A method according to claim 2 wherein the thermosetting adhesive layers are initially made tacky when the laminated film is first attached to the support member and the MST device and subsequently heated to their curing temperature.
17. A method according to claim 2 wherein the thermosetting adhesive layers have different curing temperatures so that the laminated film is cured to the support member before the MST device is attached without the MST device side thermosetting adhesive curing until after the MST device is attached.
18. A method according to claim 2 wherein the opening is formed before the laminated film is attached to the mounting surface of the support member.
19. A method according to claim 1 wherein the MST device is a printhead IC and the support structure is a liquid crystal polymer (LCP) molding.
20. A method according to claim 2 wherein the support structure has at least one fiducial marker on the mounting face and the array of openings is aligned with the array of outlet apertures using a vision system tracking a predetermined opening within the array of openings, relative to the at least one fiducial marker.
