An electronic module for a transmission control unit, comprising:
- a printed circuit board that has an electronic component,
- wherein the electronic component is electrically connected to a surface of the printed circuit board at least at one point,
- wherein the electronic component and the at least one point are substantially covered with a protective coating,
- wherein the protective coating includes a media-tight protective lacquer,
- wherein the electronic component is a semiconductor component contained in a housing,
- wherein the media-tight protective lacquer is located inside the housing such that the electronic component is protected from transmission fluid that enters a space between a housing cap and the protective coating, and
- wherein the media-tight protective lacquer contacts the housing at least at one transition such that the media-tight protective lacquer is located between the housing and the surface of the printed circuit board.
A transmission control unit, comprising:
- a printed circuit board that has an electronic component,
- wherein the electronic component is electrically connected to a surface of the printed circuit board at least at one point,
- wherein the electronic component and the at least one point are substantially covered with a protective coating,
- wherein the protective coating includes a media-tight protective lacquer,
- wherein the electronic component is a semiconductor component contained in a housing, and
- wherein the media-tight protective lacquer is located inside the housing such that the electronic component is protected from transmission fluid that enters a space between a housing cap and the protective coating;
- and
- a carrier plate,
- wherein the printed circuit board is placed on the carrier plate, and
- wherein the transmission control unit is designed to be exposed to a transmission fluid.
