An electronic unit is produced including at least one electronic component at least partially embedded in an insulating material. A film assembly is provided with at least one conductive layer and a carrier layer. The conductive layer includes openings in the form of holes for receiving bumps, which are connected to contact surfaces of the at least one electronic component. The at least one component is placed on the film assembly such that the bumps engage with the openings of the conductive layer. The at least one component is partially embedded from the side opposite of the bumps into a dielectric layer. The carrier layer of the film assembly is removed such that the surface of the bumps is exposed. A metallization layer is then deposited on the side of the remaining conductive layer having the exposed bumps and so as to produce conductor tracks that overlap with the bumps.

Electronic assembly including an embedded electronic component

The present invention relates to a method for the production of an expandable circuit carrier in which a starting material for an expandable substrate is applied on an electrically conductive foil which forms an expandable substrate layer which is connected to the foil, after which the foil is structured such that it forms a conductor structure having at least one expandable strip conductor. The present invention further relates to an expandable circuit carrier which can be produced by the method.

Expandable circuit carrier

A method is provided for making an electrical connection with a microelectronic component arranged on or embedded within a surface of a circuit board layer or a substrate. The microelectronic component has an electrical contact face that is accessible on a surface of the microelectronic component. An electrically conducting bump is applied to the electrical contact face of the microelectronic component. A metal foil or metal coat is applied via a coating of an insulating binder to the surface of the circuit board under an action of pressure and/or heat so that the electrically conducting bump penetrates the coating of the insulating binder to make the electrical connection between the metal foil or metal coat and the electrical contact face.
