The construction of SMT product assembly quality management system will eventually achieve the following goals:
(1) Establish a reliable and complete quality assurance system;
(2) Use computer and network database, expert system and other technologies to complete quality data collection, statistics, analysis and feedback;
(3) Realize product quality inspection and control in the assembly and production process of SMT products to ensure that the product quality is qualified.
The structure of the SMT product assembly quality management system can be divided into three levels: the management layer, the execution layer and the inspection unit layer.
(1) The management mainly completes the functions of quality assurance plan and implementation method formulation, quality information management, quality data analysis and statistics, quality report recording, quality cost and accident statistics and analysis, and its work is mainly performed by the decision-making body of the quality management system Responsible separately from the quality assurance department and the quality management team.
(2) The executive level mainly completes the collection of on-site quality data, statistical analysis, running statistical analysis software, modifying related quality control documents, printing or displaying quality reports, outputting quality control feedback information, etc. Its work is mainly performed by the quality management of the quality management system The group and the quality inspection group are responsible respectively.
(3) The inspection unit layer mainly completes the accurate collection, analysis and delivery of quality information, and its work is mainly undertaken by the quality inspection team of the quality management system.
When the SMT product assembly quality management system is running, the executive layer will start the collection of quality information at each inspection point according to the instructions of the management, and conduct preliminary sorting and analysis; then send the inspection content to the quality management for statistics and analysis; by the management Produce final quality analysis results and quality control information. The collected quality information, statistical reports, analysis reports, and related quality control information can be displayed or output through terminal monitoring PCs at all levels for analysis by quality inspectors.
