PROBLEM TO BE SOLVED: To provide a method of manufacturing a circuit carrier and the use of the method.SOLUTION: The method comprises: providing a printed circuit board (a); coating the circuit board on at least one side thereof with a dielectric (b); and structuring the dielectric for producing trenches and vias therein using laser ablation (c). Then, an undercoat layer is deposited onto the dielectric, either onto the entire surface thereof or into the produced trenches and vias only (d). A metal layer is deposited onto the undercoat layer, with the trenches and vias being completely filled with metal for forming conductor structures therein (e). Finally, the excess metal and the undercoat layer are removed until the dielectric is exposed until the undercoat layer is deposited onto the entire surface thereof, with the conductor structures remaining intact (f).
