    • A wiring board includes: a flexible insulating base 1; a plurality of conductive wirings 2 arranged on the flexible insulating base 1; protruding electrodes 3 provided respectively at an end portion of the same side of each of the conductive wirings; external terminals 4, 5 formed respectively at the other end portions of each of the conductive wirings; metal plating layers applied on the conductive wirings, the protruding electrodes and the external terminals; and solder resist layers 7 formed respectively by coating the conductive wirings in regions between the end portions at which the protruding electrodes are provided and the external terminals. In the regions where the solder resist layers are formed, no metal plating layers are formed on the conductive wirings, and the surfaces of the conductive wirings to be contacted with the flexible insulating base are rougher than the surfaces not to be contacted with the flexible insulating base. Even when a film base is thin, bending stress applied to the conductive wirings is relieved sufficiently, and thus breaks in the wirings are suppressed.
    • 布线板包括:柔性绝缘基座1; 布置在柔性绝缘基座1上的多个导电布线2; 突出电极3分别设置在每个导电布线的同一侧的端部处; 外部端子4,5分别形成在每个导电布线的另一端部; 施加在导电布线,突出电极和外部端子上的金属镀层; 以及分别通过在设置有突出电极的端部与外部端子之间的区域中涂覆导电布线而形成的阻焊层7。 在形成阻焊层的区域中,在导电布线上不形成金属镀层,与挠性绝缘基体接触的导电配线的表面比不与柔性绝缘体接触的表面更粗糙 基础。 即使当薄膜基底较薄时,施加到导电布线的弯曲应力被充分地减轻,因此抑制布线中断。

    • A flexible insulating base, a plurality of conductor wirings provided on the base, and a plurality of bump electrodes that are formed on the plurality of conductor wirings, respectively, are provided. A semiconductor chip having electrode pads is to be mounted by placing the semiconductor chip on the bump electrodes and bonding the electrode pads and the bump electrodes, respectively. The bump electrodes are placed on the conductor wirings, respectively, in edge portions of at least two sides of a chip mounting region in which the semiconductor chip is to be mounted. The conductor wiring corresponding to at least one of the bump electrodes placed in the edge portions of the two sides passes through the chip mounting region so as to be routed via a side different from the side on which the at least one of the bump electrodes is placed, and then led to an outside of the chip mounting region. It is possible to route wirings more freely for leading conductor wirings from bump electrodes placed in an edge portion of a semiconductor chip mounting region to an outside of the chip mounting region.
    • 提供柔性绝缘基座,设置在基座上的多个导体布线和分别形成在多个导体布线上的多个凸块电极。 通过将半导体芯片放置在凸块电极上并分别结合电极焊盘和凸块电极来安装具有电极焊盘的半导体芯片。 凸起电极分别放置在芯片安装区域的至少两侧的边缘部分中,半导体芯片将要安装在其中。 对应于放置在两侧边缘部分中的凸起电极中的至少一个凸起电极的导体布线通过芯片安装区域,以便经由与其中至少一个凸起电极的侧面不同的一侧 放置,然后引导到芯片安装区域的外部。 可以更加自由地将布线布线从位于半导体芯片安装区域的边缘部分中的凸起电极引导到芯片安装区域的外部。
