Abstract:
1. A method of manufacturing a flex-rigid wiring board, comprising: disposing a non-flexible substrate and a flexible board side by side in a horizontal direction of the non-flexible substrate and the flexible board such that an end portion of the non-flexible substrate is positioned adjacent to an end portion of the flexible board and forms a boundary between the flexible board and the non-flexible substrate with respect to the end portion of the flexible board; covering the boundary between the flexible board and the non-flexible substrate with an insulating layer such that the insulating layer is positioned on the flexible board and the non-flexible substrate across the boundary between the flexible board and the non-flexible substrate; forming a second conductor pattern on the insulating layer; forming a via hole which passes through the insulating layer and reaches a first conductor pattern of the flexible board; and plating the via hole such that a via conductor connecting the first conductor pattern of the flexible board and the second conductor pattern on the insulating layer, wherein the flexible board comprises a flexible substrate and the first conductor pattern formed over the flexible substrate.
