Abstract: An arrangement includes a housing and a printed circuit board (PCB) arranged vertically above the housing. The housing includes: at least one protrusion attached to sidewalls and arranged on an outside of the housing at a lower end with at least one first through hole provided in the protrusion; holding devices each arranged inside a first through hole and/or between the PCB and the first through hole; and fastening elements configured to attach the housing to a heat sink or base plate. Each holding device is configured to clamp a corresponding fastening element such that the fastening elements are secured in defined positions, and to align each fastening element with a different first through hole. The PCB includes second through holes each arranged vertically above and aligned with a different fastening element. A diameter of each second through hole is less than the largest diameter of the respective fastening element.
