ABSTRACT:
A rigid-flexible circuit board with two rigid areas and one flexible area, with a rigid individual layer which is copper-clad on one side, with an adhesive medium and with a copper foil, the adhesive medium having recesses in the flexible area. The rigid-flexible circuit board can be produced especially easily and economically in that at least in the rigid area there is no flexible individual layer, especially no polyimide film, between the adhesive medium and the copper foil.
