    • The present invention relates to an inkjet print head and a method for manufacturing the same. The inkjet print head comprises an injection assembly which comprises ink delivery paths in the inside and includes a nozzle plate including an injection hole discharging the delivered ink to the outside on the bottom. A printed circuit board is combined to the injection assembly, and includes an integrated circuit and a connection electrode. In the printed circuit board and the injection assembly in the combined state, a barrier coating film is comprised which covers an inner surface and an outer surface of the injection assembly and the surface of the printed circuit board except the bottom of the nozzle plate and the surface of the connection electrode, and has a flexible film, an anti-diffusion film and a hydrophobic film stacked in sequence. The inkjet print head has reduced pollution of injected ink and improved durability.
    • 喷墨打印头及其制造方法技术领域本发明涉及一种喷墨打印头及其制造方法。 喷墨打印头包括注射组件,其包括在内部的墨水输送路径,并且包括喷嘴板,喷嘴板包括将输送的墨水排放到底部的外部的喷射孔。 印刷电路板组合到注射组件中,并且包括集成电路和连接电极。 在印刷电路板和组合状态的注射组件中,包括覆盖注射组件的内表面和外表面以及印刷电路板的除了喷嘴板的底部以外的表面的阻隔涂层膜, 连接电极的表面,并且具有顺序堆叠的柔性膜,抗扩散膜和疏水膜。 喷墨打印头减少了喷墨的污染并提高了耐久性。

    • A liquid discharging head and a method of manufacturing the liquid discharging head are provided to restrain the temperature of a discharging hole of the liquid discharging head from increasing and prevent the ink temperature in a flow chamber from increasing so as to stabilize the quantity of discharged ink. A liquid discharging head includes an element, a flow channel, a substrate(101), a flow channel forming layer, a metal layer(115), and a protrusion(120). The element generates energy used to discharge a liquid from a discharging hole(116). The flow channel is connected with the discharging hole. The flow channel forming layer is bonded to the substrate to form the flow channel. The element is placed on the flow channel forming layer. The metal layer includes the discharging hole corresponding to the element. The protrusion is formed of a metal and protruded from the metal layer toward the substrate through the flow channel forming layer.
    • 提供液体排放头和液体排放头的制造方法以限制排液头的排出孔的温度增加并防止流动室中的油墨温度升高,从而稳定排出的油墨量 。 液体排放头包括元件,流动通道,基底(101),流动通道形成层,金属层(115)和突起(120)。 元件产生用于从排出孔(116)排出液体的能量。 流路与排放孔连接。 流路形成层与基板接合而形成流路。 元件放置在流道形成层上。 金属层包括对应于该元件的排出孔。 突起由金属形成,并通过流路形成层从金属层向基板突出。
