    • An ink composition includes a colorant, a solvent, and at least one component selected from the group consisting of monomer, oligomer, and macromolecule resin. The vapor pressure of the solvent is smaller than 0.33 mmHg at 20° C., but when the temperature of the solvent is between 60° C. and 90° C., the vapor pressure thereof increases at least five times than that of the solvent at 20° C. and/or the evaporation rate is larger than one tenth of that of butyl acetate at 20° C. The ink composition has excellent practicability. A manufacturing method of color filter using the ink composition includes the steps of: providing a transparent substrate; forming a black matrix on the transparent substrate; forming a plurality of banks on the black matrix; ejecting the ink composition into spaces defined by the banks via an ink jet device; and solidifying the ink composition.
    • 油墨组合物包括着色剂,溶剂和选自单体,低聚物和大分子树脂中的至少一种成分。 溶剂的蒸气压在20℃时小于0.33mmHg,但当溶剂的温度在60℃至90℃之间时,其蒸气压比溶剂的蒸气压至少要高5倍 在20℃下和/或蒸发速率大于20℃时乙酸丁酯的蒸发速率的十分之一。油墨组合物具有优异的实用性。 使用油墨组合物的滤色器的制造方法包括以下步骤:提供透明基板; 在透明基板上形成黑色矩阵; 在黑矩阵上形成多个堤; 通过喷墨装置将墨水组合物喷射到由堤岸限定的空间中; 并固化该油墨组合物。

    • The invention discloses a manufacturing processing of making a flexible printed circuit for inkjet printheads. Through the change of the flexible printed circuit structure, residual stress at the bent part can be reduced and the efficiency and precision of subsequent processes can be increased. The disclosed process is thus able to make products with high reliability and quality. The process involves the steps of: (1) preparing a flexible printed circuit substrate and making a window at a predetermined bent part; (2) coating the substrate with a metal layer so that the substrate become conductive; (3) etching the metal layer through a photolithography process to produce a conductive circuit on the flexible printed circuit; and (4) forming a cover layer (solder mask materials such as epoxy or acrylic resins) at the window. A flexible printed circuit thus produced is pre-bent, easy to attach and align, and has less residual stress and a cover layer or film at the bent part.
    • 本发明公开了一种制造用于喷墨打印头的柔性印刷电路的制造工艺。 通过改变柔性印刷电路结构,可以减少弯曲部分的残余应力,提高后续工艺的效率和精度。 因此,所公开的方法能够使产品具有高可靠性和高质量。 该方法包括以下步骤:(1)制备柔性印刷电路基板并在预定弯曲部分制作窗口; (2)用金属层涂覆基板,使基板变得导电; (3)通过光刻工艺蚀刻金属层,以在柔性印刷电路上产生导电电路; 和(4)在窗口处形成覆盖层(诸如环氧树脂或丙烯酸树脂的阻焊材料)。 如此制造的柔性印刷电路预弯曲,易于附着和对准,并且在弯曲部分处具有较小的残余应力和覆盖层或膜。
