Abstract: An electronic device comprising an electrically conductive core layer with a first layer composed of electrically conductive material, the first layer being applied on both sides and with at least one electronic component arranged in a cutout of the first layer, wherein the first layer is covered in each case with an electrically insulating, thermally conductive layer and a further layer composed of electrically conductive material is provided in each case on the thermally conductive layer, the further layer being coated in each case with a covering layer composed of electrically conductive material, and furthermore having plated-through boles composed of the material of the covering layer, which extend through the electrically insulating, thermally conductive layer covering the electronic component and the further layer composed of electrically and thermally conductive material for the purpose of making contact with the electronic component.

Abstract: A printed circuit board multilayer construction comprising a layer stack composed of plurality of electrically insulating and/or conductive layers arranged one above another and a cavity in the interior of the layer stack, which extends laterally only in a partial region of the areal extent of the layer stack, is exposed to a pressure surrounding the printed circuit board multilayer construction through an opening provided in the layer stack and is sealed relative to ingress of liquid. Furthermore, the present invention relates to a method suitable for producing a printed circuit board multilayer construction of this type.

Abstract: The present invention relates to a method for producing a conductor structural element, comprising providing a rigid substrate, electrodepositing a copper coating on the rigid substrate, applying a conductor pattern structure to the copper coating, then possibly mounting components, laminating the substrate with at least one electrically insulating layer, detaching the rigid substrate, at least partially removing the remaining copper coating of the rigid substrate in such a way that the conductor pattern structure is exposed.

Abstract: The invention relates to a multilayer printed circuit board structure comprising a stack of plurality of electrically insulating and/or electroconductive layers and at least one passive or active electrical component arranged inside the stack of layers, the component extending laterally only in part of the surface extension of the stack of layers. The invention also relates to a passive or active electrical component mounted on the stack, to an associated wiring, and to a corresponding production method. According to the invention, the insert is embedded between two electrically insulating liquid resin layers or prepreg layers extending over the entire surface and covering the insert on both sides, the insert being surrounded by a resin material that is liquefied by compression or lamination of the structure. The invention structure can be used in printed circuit board technology.
