The Spc-based Electronic Components Production Process Quality Control System

Modern enterprise need to live and develop,even join in the civil and international competition, the quality of product is most important, which is the life of enterprise. Many factors affect the quality of enterprise's product, they come from the enterprise itself and outer factors. Outer factors primarily are the effect of the enterprise's goods inwards(That is material,outsourcing). Inner factors primarily are the effect of quality of manufacture process. Therefore,it is important content in the quality management of modern enterprise that controlling material,outsourcing,selecting qualified purchasers and performing the all-round quality valuation,strengthening the quality control of product manufacture process is the most important part of quality management in all enterprises.Quality, to some extent, is the life line of an enterprise,and the quality of production is formed in the produce process. As SPC (Statistical Process Control) controls quality efficiently by using statistical methods and it is advanced and more popular method on the current international, it is necessary to research and develop a SPC-based quality control system in manufacture process in order to control the quality of the productions. In this paper, the framework of the system was built and planned, then the function model is designed after took account of factors such as man,machine,material,method,environgment and measure. Especially common statistic tools in quality management are studied.Firstly, the Statistical Process Control (SPC) theory and its application methods were introduced briefly,and the characteristic of production line was considered in the transmission Plant,then,The Quality Control System in Manufacture Process Based on SPC was developed in this dissertation. The system design of the overall program, including the technical processes, the core evaluation technologies, the system architecture, the application topology, and the system functional modules have been design in detail; and the database was designed; the key technologies such as quality control methods, quality diagnostic module was studied; meanwhile the system interface wass designed, and SPC methods had been applied in quality control in the actual manufacture processFor the Quality Control System in Manufacture Process Based on SPC software of the transmission Plant,its interfaces are friendly,the design method is scientific,the analysis processing is detailed,and the conclusion is right by some examples,the Quality Control System in Manufacture Process Based on SPC achieves all original design requirement,and it can be adopt to the production quality control of the corporation.
