Abstract: Manufacturing method and circuit module, which comprises an insulator layer and, inside the insulator layer, at least one component, which comprises contact areas, the material of which contains a first metal. On the surface of the insulator layer are conductors, which comprise at least a first layer and a second layer, in such a way that at least the second layer contains a second metal. The circuit module comprises contact elements between the contact areas and the conductors for forming electrical contacts. The contact elements, for their part, comprise, on the surface of the material of the contact area, an intermediate layer, which contains a third metal, in such a way that the first, second, and third metals are different metals and the contact surface area (ACONT 1), between the intermediate layer and the contact area is less that the surface area (APAD) of the contact area.

Abstract: A method for the manufacture of a circuit board containing a component and circuit board containing a component. The invention is based on first manufacturing an intermediate product, which contains the insulator layer of the circuit board and the components, which are set in place inside the insulator layer in such a way that the contact elements of the components face the surface of the intermediate product. After this, the intermediate product is transferred to the circuit-board manufacturing line, on which a suitable number of conductor-pattern layers and, if necessary, insulator layers are manufactured on one or both sides of the intermediate product, in such a way that, when manufacturing the first conductor-pattern layer, the conductor material forms an electrical contact with the contact elements of the components. Alternatively, stages can also be performed on a single manufacturing line.

Abstract: The present publication discloses a method for manufacturing a circuit-board structure. In the method, a conductor layer is made, which comprises a conductor foil and a conductor pattern on the surface of the conductor foil. A component is attached to the conductor layer and the conductor layer is thinned, in such a way that the conductor material of the conductor layer is removed from outside the conductor pattern.
