Dear technetters, How do all of you in the no-clean world monitor and control board cleanliness. In the days of OA flux, we used an Ionograph or Omegameter to monitor our 'cleaning' process. Do some of you still use an ionic contamination tester or do you use SIR testing or nothing or what? Thanks in advance for your advice.
