    Abstract: The invention relates to a power electronics component that comprises a planar ceramics substrate (2) on whose one face condutor tracks (6), applied in thick-film technique, are disposed for electrically connecting electrical power components (7) of a circuit that are also disposed on the ceramics substrate (2). The ceramics substrate (2), with its other face, is brazed onto a metal support element (1) that serves as a heat spreader. The support element (1) is linked with a thermoconducting housing part (9) of a housing that accommodates the support element (1) in a thermoconductive manner. On the face of the support element (1) facing away from the ceramics substrate (2), approximately opposite the ceramics substrate (2), a second ceramics substrate (4) is brazed onto the ceramics substrate (2) that carries the circuit and has approximately the same dimensions.

    Abstract: A transmitter includes an RF board having a circuit for processing high frequency signals, an IF board having a circuit for processing intermediate frequency signals, a shield plate formed of a conductive material arranged between the boards for shielding electromagnetic waves generated from the circuits, a board-to-board connecting wire inserted to a through hole based by a gap sufficient to avoid electric influence from an inner wall surface of the through hole provided in the shield plate, to be connected to through hole lands provided on the RF board and a IF board, respectively, and connectors formed of an insulating material and attached near opposite ends of the board-to-board connecting wire and sandwiching the shield plate, for fixing the board-to-board connecting wire to the shield plate. This provides a wiring connection structure that facilitates connection between circuit boards with each other and stably realizes normal signal transmission.

    Abstract: PROBLEM TO BE SOLVED: To provide a circuit board unit for removing the heat dissipated from SMDs in power electronic applications, and to provide a method for production thereof. SOLUTION: The circuit board unit comprises a circuit board topmost laminate 8 with conductive tracks 10 on the upper side for mounting surface-mountable devices SMDs 12, 14. The circuit board topmost laminate 8 features a thickness dimensioned such that the anticipated heat dissipated by the SMDs 12 is transported from the upper side to the underside of the circuit board topmost laminate 8 to good effect. The circuit board unit further comprises an electrically insulating laminate 9 arranged under the circuit board topmost laminate 8, inserts 15 made of a material with good heat conductivity and electrical insulation embedded in the electrically insulating laminate 9 at sides below SMDs 12 with high heat dissipation, and a cooling plate 16 arranged below the electrically insulating laminate 9 and the inserts 15.
