Abstract:
A method of manufacturing a wiring board including forming a base substrate, forming a first insulation layer on a first surface of the base substrate and a second insulating layer on a second surface of the base substrate opposing the first surface, forming an IVH (Interstitial Via Hole) that penetrates the base substrate, forming vias in at least one of the first substrate or second substrate, and cutting the first insulating layer in a first area and cutting the second insulating layer in a second area offset from said first area to form a first substrate laminated to a second substrate with the base layer interposed therebetween, the second substrate having a smaller mounting area than a mounting area of the first substrate such that the first substrate extends beyond an edge of the second substrate.
Abstract:
A wiring board and method of forming a wiring board. The wiring board includes a first substrate and a second substrate having a smaller mounting area than a mounting area of the first substrate. A base substrate is laminated between the first substrate and the second substrate such that the first substrate extends beyond at least one edge of the second substrate. At least one of the base substrate, the first substrate or the second substrate comprises pliable resin, and at least one other of the base substrate, the first substrate or the second substrate comprises an inorganic filler.
Abstract:
A flex-rigid wiring board including a rigid wiring board including a rigid base material and having a conductive layer over the rigid base material, and a flexible wiring board including a flexible base material and having a conductive layer over the flexible base material. The conductive layer of the flexible wiring board is electrically connected to the conductive layer of the rigid wiring board. The flexible wiring board has a cut portion and one or more folding portions formed by using the cut portion and folding one or more portions of the flexible wiring board such that the flexible wiring board is extended in length.
Abstract:
A flex-rigid wiring board includes a flexible board including a flexible substrate and a conductor pattern formed over the flexible substrate, a non-flexible substrate disposed adjacent to the flexible board, an insulating layer covering the flexible board and the non-flexible substrate and exposing one or more portions of the flexible board, a conductor pattern formed on the insulating layer, and a plating layer connecting the conductor pattern of the flexible board and the conductor pattern on the insulating layer.
