    摘要： Disclosed is an inkjet print cartridge including an ink reservoir; a substrate having a plurality of individual ink firing chambers with an ink firing element in each chamber along a top surface of said substrate and having a first outer edge along a periphery of substrate; the first outer edge being in close proximity to the ink firing chambers. The ink firing chambers are arranged in a first chamber array and a second chamber array and with the firing chambers spaced so as to provide 600 dots per inch printing. An ink channel connects the reservoir with the ink firing chambers, the channel including a primary channel connected at a first end with the reservoir and at a second end to a secondary channel; the primary channel allowing ink to flow from the ink reservoir, around the first outer edge of the substrate to the secondary channel along the top surface of the substrate so as to be proximate to the ink firing chambers. A separate inlet passage defined by a barrier layer for each firing chamber connecting the secondary channel with the firing chamber for allowing high frequency refill of the firing chamber. The separate inlet passage for each firing chamber having peninsulas and pinch points formed in the barrier layer to prevent cross-talk and overshoot during high frequency operation. A group of the firing chambers in adjacent relationship forming a primitive in which only one firing chamber in said primitive is activated at a time. A first circuit on said substrate connect to the firing elements and a second circuit on the cartridge connect to the first circuit, for transmitting firing signals to the ink firing elements at a frequency greater than 9 kHz. The preferred configuration of the nozzle member, ink channels, and vaporization chambers allows a printing resolution of 600 dpi and a firing rate of greater than 9 kHz.

    摘要： A TAB circuit particularly suited for an ink jet pen and method of manufacture. A TAB circuit is presented which incorporates a central isolation area within the TAB circuit and an ESD protective ring which surrounds the TAB circuit. To facilitate plating, all of the active TAB traces are shorted together by individual plating interconnects located generally within the central isolation area. These interconnects are arranged in a staggered pattern such that sufficient clearance is available to punch out the interconnects without damaging an adjacent trace. The central isolation area is positioned between the TAB circuit window and the terminal pads. When the TAB circuit is mounted on an ink jet pen, the central isolation area is in a "wrap area" of the pen so no additional TAB circuit area is required over what is needed to properly position the TAB circuit on the pen. In addition, since the isolation area is located above an area of the pen housing that is provided with an insulation layer, the risk of the punched traces shorting to the pen housing is eliminated.
