How do you evaluate board cleanliness after cleaning, or after no-clean processing?
We use dedicated test equipment for this purpose.
We send boards periodically for testing and analysis.
We discover cleanliness issues in failure analysis.
Our cleaning equipment also provides cleanliness test.
We don't evaluate cleanliness.
We check for cleanliness during visual inspection.
