Patent ID: 8525038

Claim:
A flex-rigid wiring board comprising: a flexible board comprising a flexible substrate and a conductive layer formed over the flexible substrate, the conductive layer having a conductor pattern and a plurality of connection portions connected to the conductor pattern; a non-flexible substrate disposed adjacent to the flexible board; an insulating layer comprising an inorganic material and covering the flexible board and the non-flexible substrate, the insulating layer exposing at least one portion of the flexible board; a conductive layer formed on the insulating layer and including a conductor pattern; and a via hole conductor formed in the insulating layer and connecting the conductive layer on the insulating layer and the conductive layer of the flexible board at the plurality of connection portions; and a second insulating layer covering the flexible board and the non-flexible substrate and exposing the at least one portion of the flexible board, wherein the insulating layer covers surfaces of the flexible board and the non-flexible substrate on a first side and the second insulating layer covers surfaces of the flexible board and the non-flexible substrate on a second side opposite to the first side.
