A fixing system for printed circuit boards arranged one above the other in an electronics housing, in particular for automotive applications. One printed circuit board is fixed to the electronics housing by a rigid fixing means and all of the other printed circuit boards are fixed by way of sprung fixing means. The is provided an advantageous fixing system for printed circuit boards arranged one above the other in an electronics housing which makes it possible for the printed circuit boards to be mounted in a stress-free manner, but in the process forms defined thermal transition regions, and which requires little installation space on the printed circuit board. It is particularly suitable for automotive applications.
