    • A method of attaching an ink-jet printhead assembly to the headland region of an ink-jet pen cartridge. The cartridge includes a frame structure fabricated of a rigid plastic frame member formed of a first plastic material and a polymeric second material molded to the frame member. A headland region is defined at the tip of a snout region of the cartridge. The second plastic material forms a compliant beam at the headland region. The printhead assembly includes a dielectric layer and a printhead die. The printhead assembly is attached to the headland region after alignment by attaching the dielectric layer of the assembly to the compliant beam formed by the second plastic material. As the pen is subjected to temperature extremes, and the first plastic material expands or shrinks more than the cover layer and flexible interconnection circuit materials, the compliant beam flexes, reducing stresses which can lead to pen failures.
    • 一种将喷墨打印头组件附接到喷墨笔筒的岬角区域的方法。 盒包括由第一塑料材料形成的刚性塑料框架构件和模制到框架构件的聚合物第二材料制成的框架结构。 岬角区域限定在药筒的鼻部区域的尖端。 第二种塑料材料在岬角区域形成柔顺梁。 打印头组件包括电介质层和打印头芯片。 打印头组件通过将组件的电介质层连接到由第二塑料材料形成的柔性梁上而在对准之后附接到岬角区域。 当笔受到极端温度的影响时,第一塑料材料比覆盖层和柔性互连电路材料膨胀或收缩更多,柔性梁弯曲,减少了可能导致笔错的应力。

    • A method of attaching an ink-jet printhead assembly to the headland region of an ink-jet pen cartridge to form a leak-proof seal without the use of any externally applied adhesive material. The cartridge includes a frame structure fabricated of a rigid plastic frame member formed of a first plastic material and a polymeric second material molded to the frame member. A headland region is defined at the tip of a snout region of the cartridge. An ink reservoir is connected through a standpipe defined by the rigid frame material with the headland region. The second plastic material defines a printhead assembly support structure which circumscribes a printhead and the stand-pipe. The printhead assembly is attached to the support structure after alignment by heatstaking the printhead assembly to the second plastic material defining the support structure. For an edge-fed printhead secured to a back surface of a flexible polymer tape, the support structure is a racetrack extending from a surface of the headland region, to which the back surface of the tape is heat staked. For a center-fed printhead die, the support structure is a pedestal surrounding the standpipe, to which the die is bonded by melting and reflowing the pedestal material.
    • 一种将喷墨打印头组件附接到喷墨笔筒的岬角区域以在不使用任何外部施加的粘合材料的情况下形成防漏密封的方法。 盒包括由第一塑料材料形成的刚性塑料框架构件和模制到框架构件的聚合物第二材料制成的框架结构。 岬角区域限定在药筒的鼻部区域的尖端。 墨水储存器通过由刚性框架材料限定的竖管与岬角区域连接。 第二塑料材料限定了打印头组件支撑结构,其包围打印头和支架。 打印头组件通过将打印头组件加热到限定支撑结构的第二塑料材料而在对准之后附接到支撑结构。 对于固定到柔性聚合物胶带的后表面的边缘馈送打印头,支撑结构是从岬角区域的表面延伸的跑道,带的后表面被热定位到该跑道。 对于中心馈送的打印头模具,支撑结构是围绕立管的基座,通过熔融和回流基座材料将模具结合到该基座上。
