Abstract: The invention relates to a printed board which comprises an inlay and on whose one face electrical components are provided and on whose other face at least one single cooling element for cooling the components is mounted. A component to be cooled, the inlay and the cooling element are aligned with each other. The components are SMD components of, e.g., a high-power output stage circuit with heat emissions of up to 10 to 15 watt. In order to cool the structure, the heat produced in a heating zone between the pins of a component to be cooled is guided to the inlay which is dimensioned in such a manner that it extends farther than below the pins of the component to be cooled.

Abstract: The invention relates to a contact system comprising a spring and an accordingly associated printed circuit board surface, with which the spring is in contact. The printed circuit board surface to be contacted is a carbon printed circuit board surface. Increased contact resistance between the spring and the carbon printed circuit board surface, which is associated with the contact system according to the invention, is furthermore compensated for by electric and/or electronic means. The spring that is used is provided with a spring force adapted to the carbon printed circuit surface.

Abstract: A method is proposed for producing printed circuit board structures with possible realization options including adhesiveless, flexible and with the smallest via holes with diameters for example of the order of magnitude between 1 and 5 ?m. The method is based on a supporting means for the circuit board structure which is still without any copper cladding. The passage holes are shot through or lasered especially for the smallest via holes with the aid of heavy ions or a precision laser in the supporting material provided on its own in this way. The surface of the supporting means is not clad with copper until after this process. When this is done the electrical via holes are contacted simultaneously. If the supporting means is for example flexible polyimide and not yet preprocessed for copper cladding, the surface of the supporting means can be roughened at the same time as the holes are made by controlling the intensity of heavy ion acceleration or the precision laser appropriately.

Abstract: A method for producing printed circuit board sets capable of being made, among other things, without adhesive, in flexible manner and with very small transverse connections with diameters of the order of 1 to 3 ?m. The method uses, as starting material for the printed circuit board set, a support element free of any copper layer. The through holes, in particular for the smallest transverse connection, are made by spraying heavy ions into the obtained material. Only subsequently the surface of the support element are coated with a copper film. The electrical transverse connections are thus simultaneously produced. If the support element is, for example, flexible polyimide and it has not been pretreated for the copper plating, it is possible to use the heavy ion process not only to produce the holes, but also to make the surface rough. The desired printed circuit board set is then completed according to the usual methods.

Abstract: A method for producing printed circuit boards and/or corresponding constructs that includes points where through-connections are created. The method vitiates the need for a very complex brushing process by using low cost lacquer variants. Moreover, the disclosed methods allow additional strip conductors or appropriate layers to be guided directly across the through connections rather than just to the through connections.

Abstract: A mobile communication terminal with a processor control is disclosed, wherein the terminal includes at least one independent humidity sensor controlled by the processor to detect humidity for the purpose of reducing or preventing corrosion in the mobile communication terminal. Upon detection of humidity, either a complete or partial shut down of the mobile communication terminal is effected. In particular, during a partial shut down, those components necessary for detection of humidity and for reactivating the mobile communication terminal remain active. Additionally, functional components are protected from corrosion by reducing voltage differentials when humidity is detected.

Abstract: A printed circuit board for electrical devices having RF components, particularly for mobile radio telecommunication devices, wherein to increase the packing density of electronic circuits and conductor-track structures on such circuit board, a “micro via” coating is initially applied to one or both sides of a printed circuit board assembly. This “micro via” coating then has, in particular, RF circuits and RF conductor-track structures applied to at least part of its surface. Finally, the RF circuits and RF conductor-track structures are protected in relation to an RF ground coating of the printed circuit board assembly by barrier areas arranged in an assembly coating, situated directly below the “micro via” coating, of the printed circuit board assembly against interfering influences which impair the RF parameters, to be set in each case, of the RF circuits and RF conductor-track structures.
