My question to fellow TechNetters is:
What are some typical Ionic Contamination Levels seen at Pre-Soldermask
application and Final levels of bare board before shipping?
Do other end users require monitoring of Pre-Soldermask levels of Ionic
Contamination or just at final?
We are currently going to specify 10 micro grams/sq" does anyone else
specify anything tighter? Is there a cost associated at the boasrd level
to spec something tighter.
