Aiming at problem of a kind of sensor is recalled in batch due to quality issues and still below standard after all kinds of process test

find out and confirm that the combination method and application position of leading wire and glue is the key process innovation parameters by adopting the design of experiment（DOE） quality analysis method

combining with the Minitab statistical tools

and staged import DOE various factors experiment creatively.The results indicate that this DOE new models importing experimental factors phased have made a great contribution to reduce times of experiments

lower the experiment difficulties

and also has good practical significance to complex engineering and technology research and innovation.
