The most commonly used charts are Xbar-R control charts for variable data and the P control chart for fraction nonconforming. The purpose of this study is to show how to apply the appropriate control charts for the printed circuit board process, in order to correctly detect the abnormality of the process and achieve the purpose of stable process. The non-traditional control charts considered in this study include I-MR-R/S control charts,Z-MR control charts and regression control charts.
