1. A method for detecting a leak in a vacuum assembly, comprising:
identifying a leak area, comprising
supplying a vacuum assembly which has a plurality of sensors for detecting a parameter,
detecting values of the parameter over time during evacuation of a cavity of the vacuum assembly,
creating, with an evaluation unit, a value-time curve for each sensor of the vacuum assembly from the values detected for the respective sensors,
comparing, with the evaluation unit, the value-time curves created with one another and identifying differences depending on the comparison, and
identifying the leak area in the vacuum assembly depending on the differences determined in the value-time curves and the respective position of the sensor in the vacuum assembly; and then
detecting the leak within the leak area, comprising
supplying a detection device designed to identify the leak in the vacuum assembly, and
detecting the leak within the leak area using the detection device.
