Abstract: An automated assembly and contacting of electrical components are disclosed. Before a fed component is gripped, a control device of a mounting device for mounting and contacting electrical components is provided with information associated with the component comprising, in relation to a component coordinate system of the component, the position, orientation and a relevant length of electrical connections of the component, and the position and type of handling of the handling locations of the component. A position and an orientation of the component in relation to a machine coordinate system are known to the control device. Using the position and the orientation of the component in the machine coordinate system, the control device converts the positions and orientations defined by the information associated with the component into the machine coordinate system and takes the positions and orientations into account when gripping and assembling the component.
