Abstract:
1. A method for producing a rigid-flexible circuit board, wherein at least one rigid portion or zone of a printed circuit board is connected with at least one flexible portion or zone of the printed circuit board via a layer of non-conductive material or dielectric layer, the method comprising the steps of: selectively applying a first adhesive layer on a rigid portion of the rigid-flexible circuit board in a region where a subsequent division is made; completely curing the first adhesive layer; applying a second adhesive layer on the rigid portion of the rigid-flexible circuit board in a region not covered by the first adhesive layer, the second adhesive layer is in an identical thickness as the first adhesive layer; partially curing the second adhesive layer; and connecting the rigid portion of the rigid-flexible circuit board with the flexible portion of the rigid-flexible circuit board through the second adhesive layer; wherein different regions of the first and second adhesive layers are comprised of an identical adhesive material.
