Control device and method for producing a control device for a motor vehicle

摘要

A control device includes a first circuit carrier with electrical components that are electrically conductively connected to one another and a second circuit carrier with electrical components that are electrically conductively connected to one another. The first circuit carrier and the second circuit carrier are electrically conductively connected to one another. The second circuit carrier is fixedly connected in thermally conductive fashion to a fluid-tight thermally conductive carrier element. The second circuit carrier and the carrier element are arranged in a cutout of the first circuit carrier. The carrier element has better thermal conductivity than the first circuit carrier and can be thermally conductively connected to a heat sink. The carrier element is integrated in fluid-tight fashion in an internal region of the first circuit carrier.
