For automatically placing special components 1 on circuit boards, the former are gripped at their outer contours by gripper arms 2 of a robot 3 and fed from a load station to the position at which their connector pins 4 are to be fixed within holes of the circuit board. For that purpose, the connector pins must be accurately aligned and their position relative to the gripper arms of the robot and/or their placement position must be accurately determined, considering the following parameters: component tolerances, component placement accuracy and alignment accuracy of connector pins. These parameters are evaluated in an alignment and measuring station 5, a front and a plan view of which is shown in Fig. 1 and Fig. 2, respectively.
