To analyze various failure factors by performing comparative analysis for the result of a preceding process in a packaging process and to stabilize quality by restraining quality defect.
The method has a function 2 for narrowing down a process which is considered as a factor based on repair result which is quality final information in the packaging process, a function 3 for narrowing down a process and a failure factor by comparing to the inspection result of the preceding process based on a component name and a lead number and a function 4 for narrowing down the failure factor the process based on inspection measurement result. Since quality defect can be restrained by investigating the true factor of generated failures, quality is stabilized.
