In one example, a printhead assembly includes a molding with multiple printhead dies exposed at a front part of the molding and channels in a back part of the molding to carry printing fluid to the dies. The printhead assembly also includes a printed circuit board affixed to the back part of the molding, not covering any of the channels, and an electrical connection between each die and the printed circuit board.

Laminate manifolds, and their manufacture. The laminate manifolds (18) include plates (20) arranged in parallel, forming a laminate plate stack (22), with a securing agent (24) securing the plates in the plate stack. At least some of the plates incorporate apertures (26) that are oriented in their respective plates so that when the plates are arranged in the laminate plate stack (22), the apertures define a fluidic pathway (28) that emerges from the laminate plate stack between parallel plates. The laminate manifolds are particularly useful as ink manifolds (14) for inkjet printers (10).

Assemblies for use with a fluid ejection apparatus, flexible circuit assemblies and flexible circuits. One such flexible circuit includes a flexible substrate and conductive lines adjacent the substrate. The conductive lines are capable of being operably connected with bonds of an ejector. Each of the lines has a resistance. At least one of the lines includes a length extension. A line having a length extension has substantially the same resistance as another one of the lines.

An ink jet print head, wherein injection nozzle rows for colors are formed, in staggered shape, on one sheet of nozzle sheet 23 by metal electroformed layers of Ni or a material containing Ni for specified number of injection nozzles so that a part of the specified number of nozzles can be overlapped with each other in a paper feeding direction, and a plurality of head tips 25 having a plurality of heaters are stuck, in a staggered row, on the growth surface side of the nozzle sheet 23 so that the positions of the injection nozzles and the heaters can correspond to each other, whereby printing quality can be prevented from being lowered by the displacement of the injection nozzles, and the position of the impact points of injected ink on recording paper can be stabilized.
摘要:
A method of manufacturing a printhead assembly (10) includes selecting a micromolding sub-assembly (24), the sub-assembly (24) comprising a printhead chip (18), a flexible printed circuit board (PCB, 54) and a micromolding (26). The micromolding sub-assembly (24) is attached to a cover molding (28) to form a print module (12). An ink reservoir sub-assembly (16) is formed and a plurality of the printhead modules (12) are attached to the ink reservoir sub-assembly (16) in end-to-end relationship. Ink is charged into the reservoir sub-assembly (16) and the completed assembly is tested.
