Zusammenfassung:The method involves providing a circuit board blank (1) comprising a substrate (2) and at least one electrically conductive layer (3) of a thickness that is suitable for carrying power currents. The thickness of part of the conductive layer (3) is reduced to create a signal conduction layer. The conductive layer has a thickness DL, where 150 mumat mostDLapproximately600 mum, preferably DL400 mum. An Independent claim is included for a multilayer circuit board module.
