Establish Spc Circuit Board Production And Application

Although it has only couples of years history , as an advanced assembly technology , SMT grows very fast and widely use by the informationization fast growing. It is widely applied in assembly process of electrical products in many industry areas. Because the SMT technology link to many field, the quality can be seriously impacted by many elements in the whole manufacturing process, such as raw material quality ,process precision, manufacturing cycle time, information sharing and passing, operator `s skill, the change of manufacturing environment. These elements all can serious impact the quality of finish goods. So it `s the current study point of how to use advanced quality control strategy , pick suitable quality management tool, timely and accurate feedback product's quality.This article is focusing on the electrical manufacturing service company, according to the development of this industry, more and more similar company join in. The entire oligarch joins in the drastic competition in various aspects, not only cost, but also quality, service and so on. It makes all these company using all kinds of advance technology and management in this area to upgrade the frivolousness, and create more value for customer. As an advance quality management tool, SPC very adapt to the on site timely quality control requirement for these big company.This article is basing on the statistic technology and SPC,detail describes the setup up process in WCL Company. The whole company can make it as good sample to widely apply SPC on production line. The abstruse statistic theory is completely translated to the detail simple operation step. It's really helpful for SPC widely extend and application.The setup of SPC starts from selecting suitable manufacturing process, and then according to the data collected at these process station, select the SPC control chart. The 2^nd step,basing on the statistic theory,study whether the chart selected meets the requirement. The 3^rd step is to optimize the parameter, then reset this parameter,then validate again. In the end,develop a automatically system for on line applying the SPC quality system.
