Abstract:
A circuit board construction comprising:a signal substrate layer arranged for having components mounted thereon; at least one group of signal conductors on said signal substrate layer arranged to be connected between terminals of said components; a first outer substrate layer positioned on a first side of said signal substrate layer; and a second outer substrate layer positioned on a second side of said signal substrate layer, said first outer substrate layer comprising a continuous conductive surface, said second outer substrate layer comprising a plurality of conductive areas, said conductive areas being electrically separate from each other, said circuit board construction further including a plurality of clamping vias connecting predetermined ones of said conductive areas on said second outer substrate layer with said continuous conductive surface of said first outer substrate layer in a manner such that said signal conductors between said components are positioned between conductive areas which are connected to a like potential.
