Abstract
A device for electrical and mechanical connection of an electric high-power component which transmits high-frequency electrical signals to conductors on a circuit board. The component includes horizontally projecting connections which to the are glued to the conductors on the circuit board with an electrically conducting adhesive, of which the adhesion to the foundation is greater than a predetermined value. The component is subject to repeated temperature changes which leads to stresses on the connection between the connections and the conductors. The length of the connections is chosen depending on a predetermined threshold value for the highest acceptable attenuation which the high-frequency electrical signal is subject to when passing through the electrical high-power component via the connections. The contact surface of the connections towards the glued joint can be designed so that it includes a number of cavities, whereby the adhesive achieves a better grip to the connections.
