Method for checking a mechanical connection of a heat sink holder of a heat sink assembly having a heat sink and at least one to be cooled component component, with a circuit board

摘要

The invention relates to a method for checking a mechanical connection of a heat sink holder (2) of a heat sink arrangement (1) having a heat sink (3) and at least one component component (6) to be cooled, comprising a printed circuit board (4) comprising the steps a) Providing a first electrical contact (104) and a second electrical contact (105) in or on the circuit board (4) to which the heat sink holder (2) can be connected, b) providing an evaluation unit (100) with an analog or digital input ( 101), which is connected to a voltage supply device and to the first electrical contact (104), c) generating an electrical voltage at the analog or digital input (101) of the evaluation unit (100), d) checking whether the electrical voltage at the analogue or digital input (101) is a high level voltage or a low level voltage.
