Patent ID: 8677612

Claim:
A method for manufacturing a flex-rigid wiring board, comprising: preparing a flexible wiring board comprising a flexible base material and having a conductive layer over the flexible base material; making at least one cut in the flexible wiring board such that the flexible wiring board has at least one cut portion formed; forming an insulation layer over the flexible wiring board, a first rigid wiring board and a second rigid wiring board comprising a rigid base material and a conductive layer formed over the rigid base material such that the first rigid wiring board and the second rigid wiring board are connected through the flexible wiring board at opposite end portions of the flexible wiring board after the making of the cut in the flexible wiring board; removing a portion of the insulation layer from the flexible wiring board such that the cut portion of the flexible wiring board is exposed and that a flex-rigid board structure having a flexible section comprising the flexible wiring board and a rigid section comprising the first and second rigid wiring boards is formed; and forming at least one folding portion in the flexible section of the flex-rigid board structure using the cut portion of the flexible wiring board such that the flex-rigid board structure is extended in length, wherein the cut in the flexible wiring board is formed to extend in a line perpendicular to a direction in which the first rigid wiring board and the second rigid wiring board are connected to the flexible wiring board.
