Abstract
A circuit board includes a plurality of circuit board layers arranged one on top of the other, wherein through-holes are integrated in the circuit board, wherein the through-holes are configured to receive metal screws that screw the circuit board to a heat sink. Insulating sleeves made of an insulating material are integrated into the circuit board, wherein the through-holes are formed in the circuit board in the region of the insulating sleeves.

A circuit board comprising:
- a plurality of circuit board layers arranged one on top of another;
- through-holes configured to receive metal screws that screw the circuit board to a heat sink being integrated into the circuit board;
- and
- insulating sleeves integrated into the circuit board,
- wherein the insulating sleeves comprise an insulating material,
- wherein the through-holes are formed in the circuit board in a region of the insulating sleeves, and
- wherein the insulating sleeves have a mechanical compressive strength greater than a mechanical compressive strength of a non-conductive material of the circuit board.
