This study collected and analyzed Light-Emitting Diode (LED) parameters (forward conduction voltage VF, reversed breakdown voltage, and reversed linkage current) and output information in testing LED back-end process and packaging. Moreover, it developed a remote control operation platform using LabVIEW of national instruments (NI), and provided an interface for user operation, data storage analysis, and specification evaluation. Accordingly, a remote real-time process monitoring and automatic production specification checking mechanism can be developed to replace traditional manual quality control operation, which directly deliver light-emitting diodes, while reducing high labor and production costs. Through evaluation of the proposed real-time process capability, the collected light-emitting diode parameters are automatically adjusted to the production specifications, which meet the process capability and are returned to the testing instrument in real time. The products can thus meet the process capability of the batch, the rework rate can be effectively reduced, and the passing rate of delivery quality control can be improved. The proposed remote real-time process monitoring and automatic production specification checking mechanism can analyze and evaluate production specification data, and monitor and store historical data for the long term in conjunction with the database system. Moreover, the light-emitting diode can be automatically checked by the evaluation process capability in order to improve production technology and process parameters. Thus, a solution for the optimization of light-emitting diode parameter specifications can be established to promote effective management of production equipment, improve production efficiency, and integrate production flow.
