摘要
随着电子产品集成度不断提升,表面贴装技术(SMT)对检测小波动的要求越来越高,需要使用控制图加以检测。将累积和控制图与指数加权移动平均控制图应用在SMT生产工艺中,以提高小波动的检测能力。在实际测试中确认,所设计的方法可实现SMT中锡膏印刷的高精度小波动检测,满足工业生产的要求。
Along with the continuous upgrading of the integrated level of electronic products, the ever high requirements on detection of small fluctuations in SMT need to use control chart for the detection. The CuSum control charts and the EWMA control charts were used in the SMT production process to improve the ability in detecting small fluctuations. In the actual test it confirms that the design method can realize high-precision detection of small fluctuations during solder paste printing in SMT and can satisfy the requirements of industrial production.
