    Abstract: The present invention relates to a carrier tape for TAB-package and a manufacturing method thereof, wherein a TAB tape including a base film having a central area and edge areas at both directions of the central area, a wiring pattern formed at the central area of the base film, a transfer area formed at the edge area of the base film and exposed by the base film, a plurality of sprocket holes arranged in a row on the transfer area and a metal pattern discretely formed from the wiring pattern, and formed at the edge areas of the base film, wherein the metal pattern is formed with a paired structure formed at both sides of the plurality of sprocket holes, such that the present invention has an advantageous effect in that no Cu layer or a metal layer exists at a portion of the sprocket holes from which friction is generated by a driving roller during assembly work between a drive IC and chips/drive IC and panel to dispense with generation of foreign objects such as Cu particles, thereby enhancing reliability of the product.

    Abstract translation: 本发明涉及一种TAB封装用载带及其制造方法,其特征在于,包括具有中心区域和中心区域的两个方向的边缘区域的基膜的TAB带,形成在中央区域的中央区域的布线图案 基膜,形成在基膜的边缘区域并被基膜曝光的转印区域,在转印区域上排列成一排的多个链轮孔和从布线图案离散地形成的金属图案,并形成在 基底膜的边缘区域,其中金属图案形成有形成在多个链轮孔的两侧的成对结构,使得本发明具有有利的效果,即在一个或多个链条中不存在Cu层或金属层 在驱动IC和芯片/驱动IC和面板之间的组装工作期间由驱动辊产生摩擦的部分链轮,以排除诸如Cu颗粒的异物的产生,从而 提高产品的可靠性。
