A set of circuit carriers includes a number of N≧1 circuit carriers, each of which has an upper side, an underside opposite from the upper side, a distinctive structure, and a conductor structure on the upper side. Each of the circuit carriers is populated by: determining a first relative position between the distinctive structure and the conductor structure; picking up the circuit carrier by a pickup of a lifting and positioning unit; determining a second relative position between the lifting and positioning unit and the distinctive structure of the circuit carrier picked up by the pickup; and populating the circuit carrier with one or more components while taking the first relative position and the second relative position into account.
