How Can Molders Achieve Effective Process Monitoring?

摘要

Effective process monitoring is achieved through proper process development.To monitor effectively,you must ensure that the process is optimal and repeatable.Without repeatability,effective process monitoring will never be achieved.Effective process monitoring does not simply mean setting upper and lower limits just before defects are created.This is what I call"defect limits."Although it is important to know the"defect limits"of any process,these limits are not typically tight enough to be considered effective for process control.
