Abstract
An electrical device has a printed circuit foil carrying an electrical circuit and having a throughgoing opening, a heat conductive carrier plate located at a lower side of the foil, a heating power conductor located at an upper of the foil, and a solderable edge layer located at the upper side of the printed circuit foil under the power component having dimensions corresponding to the dimensions of the power component. The edge layer limits the throughgoing opening and the foil from inside. The throughgoing opening has a side which is measured parallel to the upper side of the foil and is greater than a corresponding size of the edge layer. The throughgoing opening is filled with a heat conductive mass.
