Abstract
In the case of a multilayered printed circuit board (), more particularly a flame-resistant and/or smoke-suppressing multilayered printed circuit board, consisting of a plurality of interconnected layers () composed of incombustible, conductive material and layers () composed of non-conductive material, two layers () composed of a conductive material in each case being separated by at least one layer () composed of a non-conductive material, it is provided that the printed circuit board () contains in its interior at least two layers () having a surface proportion of at least 50%, more particularly at last 70%, composed of the incombustible, conductive material, as a result of which a multilayered printed circuit board () having improved flame resistance and reduced smoke evolution can be made available.
