With the global economic development and the improvement of consumer demand, while petition environment getting severity, even those global top enterprises could not ignore such situations. They try to pursue high-quality products and reduce waste, so keep essful in the marketing. pany is the manufacturing enterprise specializing in all kinds of mother boards, in order to pursue bigger profit, must improve quality, and reduce the return rate of the products. To achieve that, the root cause clarification of defects (failure analysis) is more important to engage in continuous improvement. The key point thesis study is to find out the failure root cause by analysis defective motherboards, propose the improvement plan, and carry out the follow up of implement and actual improving effectiveness. The thesis explains the origin of the topic through enterprise internal needs firstly. Secondly puter’s motherboard production process and the failure of current situation and failure analysis techniques, specify the failure modes and failure mechanisms of the motherboard. Then introduces foundation of the six sigma statistical met
