Abstract: A ceramic carrier substrate for an electrical/electronic circuit. The substrate includes ceramic layers arranged one above the other in an interconnected structure and conductor tracks arranged on and/or in individual ceramic layers and connected to one another as the conductor structure for the electrical/electronic circuit. The interconnected structure is formed by a firing operation. A first conductor substructure is formed in a first interconnected structure subassembly which comprises at least one of the ceramic layers, and a second conductor substructure is formed in a second interconnected structure subassembly which is directly adjacent to the first interconnected structure subassembly and comprises at least one of the ceramic layers. The second conductor substructure substantially consists of high-current conductor tracks and is configured to contact a power circuit.

Abstract: A method for producing a circuit board layer, in particular for a multilayer circuit board, a ceramic foil upon which a carrier foil is disposed being used, the carrier foil being perforated by laser to form at least one circuit trace, and/or the carrier foil and the ceramic foil being perforated together by laser to form at least one feedthrough, the circuit trace and/or the feedthrough subsequently being created by printing, the carrier foil constituting a printing screen, and the carrier foil subsequently being removed from the ceramic foil.

Abstract: An electromagnetic compatibility (EMC) filter used in a hybrid technology circuit component, having current-carrying lines and a ground conductor, for protection against electromagnetic interference. The current-carrying lines and ground conductor are arranged on a ceramic plate. The current-carrying lines are covered by a dielectric, which in turn, is covered by an upper metal screen in electrical contact with the ground conductor. A lower metal screen is arranged on the ceramic plate beneath the current-carrying lines and is in electrical contact with the ground conductor.
