The invention relates to a system component (2) of a control unit (1), in particular for transmission and engine controls of a motor vehicle. According to the invention, the system component (1) comprises a hybrid circuit (10) equipped with electronic components (11) which is embedded in a circuit board (20) which is exposed in the middle in such a way that the hybrid circuit (10) is completely enclosed by the circuit board (20) , The hybrid circuit (10) and printed circuit board (20) are mounted on a bottom element (30) and contacted via contact elements (12, 21) with each other. Finally, a cover element (40) is arranged above the hybrid circuit (10) and the contact elements (12, 21) such that the hybrid circuit (10) of the bottom element (30), cover element (40) and circuit board (20) is completely encapsulated against environmental influences , In this way, a closed system component (2) for a control unit (1), which is the first time to ship. The system component (2) according to the invention thus enables decentralized production processes and is suitable - like such comprehensive overall systems (1) - in particular for applications in motor vehicles, for example for transmission or engine control systems. |
