运用稳健六西格玛降低PMI按键压伤不良率

Using Robust Six Sigma to Reduce the Defective Rate of PMI Button Scratch

运用稳健六西格玛的知识,收集部件的尺寸和外观不良数据,通过对数据进行回归分析,找到显著变量,并建立输入变量与输出变量的函数关系,从而针对性进行部件尺寸改善,降低产品不良率。

Using the knowledge of robust six sigma,to collect the dimension and defective cosmetic data from the components,through the regression analysis for the data,to find the significant variable,and establish the function relation of input variable and output variable,so targeted to improve the dimension of parts,to reduce the defective rate of product.
