Characterization of surface mount technology component placement is essential in order to achieve true process control in an automated factory. Para- metric data about component placement accuracies is required in order to provide closed loop feedback about how a particular robot is functioning and to prevent placement defects before the process goes out of control. In order to gather this information a component measurement device is inserted into the factory line after the robots have placed the components.
