Abstract:
Manufacturing method and a multi-chip package, which comprises a conductor pattern and insulation, and, inside the insulation, a first component, the contact terminals of which face towards the conductor pattern and are conductively connected to the conductor pattern. The multi-chip package also comprises inside the insulation a second semiconductor chip, the contact terminals of which face towards the same conductor pattern and are conductively connected through contact elements to this conductor pattern. The semiconductor chips are located in such a way that the first semiconductor chip is located between the second semiconductor chip and the conductor pattern.
Abstract:
The present invention generally provides a novel method for manufacturing an electronic module with crossed conducting lines and a novel electronic module with crossed conducting lines. In particular, an aspect of the present invention is to provide a thin, single layer electronic module. It is also an object of the present invention to provide an electronic module with an embedded jumper element having reliable high quality connections and contacts. To achieve at least some of the aspects of the present invention, an embedded pre-fabricated jumper module is placed inside a printed circuit board which allows the crossing of conducting lines within the module without manufacturing additional layers over the whole PCB board. The resultant PCB will have improved contacts and will not have surface deformation.
Abstract:
Rigid-flex-type circuit-board structure and manufacturing method, in which a flexible membrane and a sacrificial-material piece are attached to an insulator membrane in the location of the flexible zone. An insulator layer, which encloses within itself a sacrificial-material piece is manufactured on the surface of the conductor membrane. The flexible zone is formed in such a way that an opening is made in the insulator layer, through which the sacrificial-material piece is removed. The flexible zone comprises at least part of the flexible membrane as well as conductors, which are manufactured by patterning the insulator membrane at a suitable stage in the method.
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.
Abstract:
An electronic module with EMI protection is disclosed. The electronic module comprises a component with contact terminals and conducting lines in a first wiring layer. There is also a dielectric between the component and the first wiring layer such that the component is embedded in the dielectric. Contact elements provide electrical connection between at least some of the contact terminals and at least some of the conducting lines. The electronic module also comprises a second wiring layer inside the dielectric. The second wiring layer comprises a conducting pattern that is at least partly located between the component and the first wiring layer and provides EMI protection between the component and the conducting lines.
Abstract:
A method for manufacturing a circuit-board structure wherein a conductor foil is provided on an insulating material layer, a resist layer is spread on the conductor foil and a recess formed in the conductor foil and insulating material layer. The resist layer is patterned to form a conductor-pattern having openings wherein conductor patterns may be grown. A component is attached to the conductor foil and conductor pattern and conductor material is removed which does not form part of a conductor pattern.
