1 PurposeThese tests are used as process controltools, they can be used to inspect printed wiring boards orprinted wiring assemblies and determine if they conform to themonitoring level of the user s performance specification. Bulkionic cleanliness testing may be accomplished by measuringthe ionizable surface contaminants extracted by the followingthree METHODS :1. MANUAL extraction method2. Dynamic extraction method3. Static extraction RestrictionsMeasurements of ionic conductivities donot differentiate between different ionic species. They simplymeasure conductivities (or resistivities) which can be related toamounts of ionic materials present in solution.
4.4.3 Suspend the test specimen within a convenient sized funnel positioned over a graduated cylinder. Care must be taken not to handle the sample or any of the …
