Method for populating a circuit board with a plurality of components and electrical circuit having a circuit board and a plurality of components mounted thereon

The invention relates to a method for populating a circuit board with a plurality of components. The method comprises the steps of: providing the components with push-through contacts extending at least in end segments of the push-through contacts in a direction perpendicular to the heat emitting surfaces of the components, and providing the circuit board with contact holes for receiving push-through contacts. At least one plastically deformable fixing element is further mounted on the circuit board. The components are mounted on the fixing element and the push-through contacts are inserted into the corresponding contact holes of the circuit board. A flat surface displaces the heat surfaces of the components toward the circuit board, plastically deforming the fixing element, until all heat emitting surfaces of the components lie in the same plane. The invention further relates to an electrical circuit having a circuit board, wherein heat emitting surfaces are connected to the circuit board by means of at leas
