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.

Multilayered printed circuit board, more particularly flame-resistant and/or smoke-suppressing multilayered printed circuit board

A thin-film assembly () including a substrate () and at least one electronic thin-film component () applied on the substrate by thin-film technology, wherein a base electrode () is provided on the substrate, on which base electrode thin-film layers () forming part of the thin-film component are arranged together with an upper top electrode (); the substrate () is comprised of a printed circuit board () known per se and including an insulation-material base body () and a metal coating as the conductor layer (), wherein the conductor layer () forms the base electrode () and, to this end, is smoothed at least on the location of the thin-film component (), and wherein a contact layer () is applied by thin-film technology between the smoothed, optionally reinforced, conductor layer () and the superimposed thin-film layers () of the thin-film component (), which contact layer is physically or chemically adsorbed on the surface of the base electrode ().
