摘要:
A silicon ink filter for a heater chip of an ink jet printhead is formed by micromachining and laser drilling. The heater chip may contain a plurality of such filters for the plurality of nozzles of the printhead. The filter comprises a via constituting an ink entrance area formed by micromachining and a plurality of bores formed at the exit side of the via produced by laser drilling. Protective layers are preferably disposed over the heater chip substrate prior to micromachining and laser drilling.

A cartridge body contains one or more printheads on a first surface thereof and one or more connection apertures in flow communication with the one or more printheads, each aperture having an opening on a second surface opposite the first surface, and one or more separate ink filtration devices, each having an ink outlet port connected to the second surface of the cartridge body through an opening so that each ink outlet port is in flow communication with at least one connection aperture. The separate devices enable production of a cartridge body made of a material which is effective for removing heat from the printheads.

The invention relates to a method for attaching a semiconductor chip to an ink jet pen body and improved construction techniques therefor. According to the method a first adhesive have a cure time greater than about 15 minutes is dispensed in a predetermined pattern in one or more chip pockets of an ink jet pen body. Beads containing a second adhesive are dispensed in two or more discrete locations around an inside perimeter of each chip pocket. A semiconductor chip having chip edges is attached to the second adhesive in each of the chip pockets and the first adhesive is cured using heat or radiation. Use of a dual adhesive system improves the alignment of the semiconductor chips relative to one another until the first adhesive is completely cured.

Disclosed is a printhead for a printer that includes a plurality of ejection chip units. Each ejection chip unit of the plurality of ejection chip units is configured to eject at least one fluid. The printhead further includes a plurality of supporting units. Each supporting unit of the plurality of supporting units is fluidly coupled with a corresponding ejection chip unit. The each supporting unit includes a plurality of trenches adapted to receive an adhesive to facilitate attachment of the each supporting unit with the corresponding ejection chip unit. Furthermore, the printhead includes a base unit fluidly coupled with the each supporting unit of the plurality of supporting units. The base unit is adapted to provide the at least one fluid to the each ejection chip unit through a corresponding to supporting unit. Further disclosed is a method for assembling the printhead.
摘要:
An ink manifold constructed with a number of semiconductor tiles which are fastened end to end on a rigid base member to form a page wide print mechanism. Each tile is constructed with ink channels on one side in liquid communication with ink outlet ports on the opposite side. The ink channels carry ink from ports in the base member to the outlet ports of the tiles. The interface between each tile defines a boundary. An inkjet printhead is fastened over each boundary of the tiled manifold so that the ink inlet ports of the printhead are aligned with the ink outlet ports of the underlying tiles. No ink passes across the boundary of the adjacent manifold tiles. The fabrication of the individual tiles from a semiconductor wafer facilitates usage of the wafer when fabricating page wide print mechanisms.
