Now electronics product development is quick a, SMT motherboard, which plays a core role in puter, munication equipment, mobile phones and other products, almost all of the calculation is done by the has e a big industry. However, for SMT production system, most of the studies are focusing on process technology improvement and quality improvement, for its material managementand material traceabilityare less researched. This paperfirst analyzes the SMT industry development background, points out the problemsof SMT materials managementin the current environment--lead to the end product material mixed. Secondly, define th
