The Technology of Quality Statistical Process Control Based on AOI Inspection Results

Aimed on the problems of complex placement problem location, graphic data association, the technology of quality statistical process control based on AOI results is proposed. Firstly, the framework of quality statistical process control technology is constructed. Then the three key technologies, which includes the quality data correlation technology, the visualization technology, the SPC analysis technology etc., are proposed in detail. By means of these technologies above, a more efficient management of the SMT production line by SMT-MES is achieved. Finally, a production management system is designed and verifies the effectiveness of the above technologies successfully.
