I have a basic question. What is the industry standard on checking
PCA cleanliness?
Basically there are various methods (ROSE, IC, etc..). For a standard
SMT
production line, is the testing done once a day, week, batch, etc.. I
understand that the
testing is to be used as a process control. Maybe some SMT lines get
the process
under control and don't do testing? What should the total ion
contamination on a standard
SMT PCA be below for a standard SMT PCA? Thank you.
Best Regards,
Michael Forrester
