The invention relates to a control device having a casing, control electronics located in the casing, and at least one electrical feedthrough. By means of the electrical feedthrough, a current is provided for a load which is located outside the casing of the control device. The electrical feedthrough is located on the casing. The casing is fluid-tight at least in part, and the electrical feedthrough is located in a fluid-tight region of the casing. The electrical feedthrough has a metal core and an insulator surrounding the metal core. The metal core has an end face. A first bond is provided between the end face of the metal core and the control electronics, the first bond being laser-bonded at the end face.
A control device (100) comprising a casing (110), control electronics (120) located in the casing (110), and at least one electrical feedthrough (130), wherein, by the electrical feedthrough (130), a current is provided for a load (200) which is located outside the casing (110) of the control device (100), wherein the electrical feedthrough (130) is located on the casing (110), wherein the casing (110) is fluid-tight at least in part, wherein the electrical feedthrough (130) is located in a fluid-tight region (111) of the casing (110), wherein the electrical feedthrough (130) has a metal core (131) and an insulator (133) surrounding the metal core (131), wherein the metal core (131) has an end face (132), wherein a first bond (140) is provided between the end face (132) of the metal core (131) and the control electronics (120), wherein the first bond (140) is laser-bonded at the end face (132), wherein the control electronics (120) is located on a printed circuit board (121) and the first bond (140) is located on the printed circuit board (121), wherein a buffer plate (122) is located on the printed circuit board (121) and the first bond (140) is laser-bonded at the buffer plate (122), wherein the printed circuit board (121) has a thermally conductive structure (123) in a region of the first bond (140), wherein the thermally conductive structure (123) is thermally conductively connected to the casing (110), wherein the thermally conductive structure (123) is electrically insulated against the casing (110).
A method for manufacturing a control device (100), wherein the method comprises the following steps:
