Claim Text:
1. A method for penetrating a flexible circuit board through a bore of a hinge assembly, the flexible circuit board comprising a first end, a second end, and an extension section extending in an extension direction between the first end and the second end, the extension section comprising a cluster structure, the cluster structure comprising a plurality of cluster lines formed by applying a plurality of cutting lines to cut the flexible circuit board in the extension direction, the first end of the flexible circuit board comprising a terminal distribution section and a connection section, wherein the terminal distribution section has a first surface and a second surface and the connection section is connected between the terminal distribution section and the extension section, the method comprising the following steps: (a) forming a pre-folding line between the terminal distribution section and the connection section of the first end of the flexible circuit board, said pre-folding line being parallel to a long dimension of the connection section and a long dimension of the terminal distribution section; (b) with the pre-folding line as a center line, folding the connection section toward the first surface of the terminal distribution section to make the connection section adjacent to the terminal distribution section, wherein the long dimension of the connection section remains parallel to the long dimension of the terminal distribution section after said folding; (c) rolling the connection section in a direction toward the terminal distribution section so as to make the resulting combination of the connection section and the terminal distribution section form a rolled body, in which the resulting combination forms a quasi-elliptical cylinder shape; and (d) putting the rolled body through the bore of the hinge assembly to have the rolled body completely extending through the bore of the hinge assembly, whereby the extension section of the flexible circuit board is positioned in the bore of the hinge assembly and the first end and the second end are respectively located at opposite sides of the bore of the hinge assembly.
