Patent ID: 10020280

Abstract:
The present invention relates to a method of manufacturing a carrier tape, 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.
