Patent ID: 7673387

Claim:
A method for manufacturing a circuit-board layer on a base surface the base surface including conductor patterns, and the circuit-board layer including a conductor pattern layer, an insulating-material layer, and inside the insulating-material layer at least one component, the method comprising: providing a conductor layer with contact openings positioned according to the contact areas of the at least one component; after providing the contact openings, attaching said at least one component to the conductor layer, on the side of a first surface of the conductor layer with the contact areas facing the contact openings in the conductor layer; aligning the conductor layer relative to the base surface and attaching the conductor layer with the aid of an insulating material to the base surface, the first surface of the conductor layer facing towards the base surface, thereby forming the insulating-material layer between the conductor layer and the base surface, said at least one component being located in said insulating-material layer; forming electrical contacts between the contact areas of the component and the conductor layer through the contact openings in the conductor layer, wherein the forming includes making conductive material in the contact openings; patterning the conductor layer to form a conductor-pattern layer; and making at least one via between the conductor-pattern layer and the conductor patterns of the base surface.
