Abstract: An externally-connected shop floor control (SFC) system comprising M shop floor control (SFC) devices is disclosed. By letting each of the M SFC devices be electrically connected between one test machine and one information read-out device, the SFC system is successfully implemented into a production line. Therefore, each of the M SFC devices is adopted to achieve a re-verification of pass record for a test object that is transferred from a previous-stage test machine, and is also adopted for collecting related test data of the test object transferred from a current-stage test machine. As such, the SFC system can be easily implemented into any one type of production line, so as to assist the manager of the production line in data collection, station passing control, manufacturing reports, and control of production efficiency and yield, without spending much cost of human resources and software/firmware developing.
