Abstract:
1. A separator plate for the production of printed circuit board components by pressing individual layers, which separator plate comprises a metallic core layer and a metal layer on at least one side of the core layer, wherein the core layer comprises a comparatively high heat-conductive metal, the core layer having an outer surface on which said metal layer is applied by cold plating, said metal layer being made of a metal having a comparatively high surface hardness compared to the core layer and a lower heat conductivity than said core layer, said separator plate being interposed between stacks of printed circuit board layers which are subjected to compression under heat, said separator plate being a composite of said core layer and said outer metal layer to provide reduced heat expansion of the core layer during pressing of the individual layers of the circuit board components while preventing image transfer to the separator plate.
