Zusammenfassung:The invention relates to a method (100) for the quality control of a component (1), wherein this component (1) comprises at least one converter element (2) which converts between a force (3) exerted on the converter element (2) or by the converter element (2) and a change in at least one electrical variable (4) of the converter element (2), wherein the converter element (2) is pressure-loaded by a preloading element (9), the method comprising the steps of: - obtaining (110) a frequency dependence (1d, 1d*) of an electrical characteristic variable (1b, 1c) of the component (1), which variable is influenced by applying, to the component (1), a voltage (1a) having an alternative voltage component; - evaluating (120b), from the frequency dependence (1d, 1d*), an evaluation variable (5a); - evaluating (130), from the evaluation variable (5a), at least one desired quality variable (6), which is a measure of the quality of the component (1). The invention also relates to a method (200) for training a machine-learning module (5) for use in the method (100).
