| Abstract: | The eccentricity was a major quality issue in hard disk assembly process.In this paper,the Hypothesis Test method is introduced and the 2-Proportion Test method is applied in identifying critical causes of the eccentricity failure.The improvement action is implemented according to the critical cause.It effectively resolves the eccentricity failure and finally improves the quality of products. |
