| dc.description.abstract | With the rapid development of technology and the increasing demand in the electronic product market, the era of Industry 4.0 has arrived. The exchange and collaboration of information between equipment have become increasingly important and indispensable. This study employs the MIAT methodology to design the overall system architecture, construct the IDEF0 functional modules of the system, and develop discrete event models for each functional module, creating Grafcet models, ultimately achieving the high-level synthesis of the software. Based on the SEMI SMT-ELS A1/A1.1 protocol specifications, this study primarily focuses on developing the horizontal communication functions between hosts and equipment as outlined in SEMI SMT-ELS A2, as well as the communication functions between equipment. By implementing core functions such as connection status management, MD reference mode management, production line route specification management, and MD transmission, the system reduces the enterprise′s labor costs and improves production efficiency. This enables companies to gain a stronger competitive edge in the fiercely competitive market environment. Thanks to standardized communication protocols and intelligent management functions, the software significantly reduces the tedious work of manually setting up each device, optimizes the overall production process, and saves a significant amount of labor costs for the enterprise. The research results can help companies address the challenges brought by Industry 4.0 and promote standardization and unity in the Surface Mount Technology (SMT) process. This is of great significance for improving the efficiency of printed circuit board production and quality control, serving as a key driver in advancing the upgrade and transformation of the printed circuit board industry. | en_US |
