    • PURPOSE: A method of forming a wiring pattern is provided to implement a wiring pattern having excellent conductivity while preventing ink from defused and improving adhesive force between substrates. CONSTITUTION: A method of forming a wiring pattern is comprised of steps: coating epoxy resin composition on a substrate in semi-hardened state to form a primer layer; firstly-printing the substrate with an ink containing a first conductive metal to depressing a seed wiring layer in the primer layer; sintering the substrate to completely harden the epoxy resin composition of the primer layer; and secondly-printing an ink containing a second conductive metal on a seed wiring layer of the substrate to form a conductive wire layer.
    • 目的:提供一种形成布线图案的方法,以实现具有优良导电性的布线图案,同时防止墨水脱落并提高基片之间的粘合力。 构成:形成布线图案的方法包括以下步骤:在半硬化状态下将环氧树脂组合物涂覆在基材上以形成底漆层; 首先用含有第一导电金属的油墨印刷基板以压下底漆层中的种子布线层; 烧结基材以使底漆层的环氧树脂组合物完全硬化; 并在基板的种子布线层上二次印刷含有第二导电金属的墨,以形成导线层。

    • An optical waveguide having a curved reflecting mirror surface and a manufacturing method thereof are provided to simply produce an optical waveguide having various curved reflecting mirror surfaces including a two-dimensional or three-dimensional curved surface, at low cost by using an inkjet method. An optical waveguide(40) is composed of a glass substrate(41) on which the optical waveguide is stacked; a clad layer(42) formed on the substrate; a core layer formed on the clad layer to transmit the light; a partition block(46) extended at the end of the optical waveguide; and a curved reflecting mirror surface having an oval shape and formed in the partition block to change an optical path toward a core by reflecting the light. The oval mirror surface is formed by dropping liquid polymer on the partition block through an inkjet header and then solidifying the liquid polymer.
    • 提供具有弯曲反射镜面的光波导及其制造方法,通过使用喷墨法简单地制造具有包括二维或三维曲面的各种弯曲反射镜面的光波导,成本低廉。 光波导(40)由其上层叠有光波导的玻璃基板(41)构成; 形成在所述基板上的覆盖层(42) 形成在所述包覆层上以透射所述光的芯层; 在所述光波导的端部延伸的分隔块(46); 以及具有椭圆形的弯曲反射镜表面,并形成在分隔块中,以通过反射光来改变朝向芯的光路。 通过喷墨头将分散块上的液体聚合物滴落,然后使液体聚合物固化,形成椭圆镜面。
