1 PurposeThese tests are used as process controltools; they can be used to inspect printed boards or printedboard assemblies and determine if they conform to the moni-toring level of the user s performance specification. Bulk ioniccleanliness testing may be accomplished by measuring theionizable surface contaminants extracted by the followingthree methods:1. Manual extraction method2. Dynamic extraction method3. Static extraction methodNote:Please note that this method does not predict reliabil-ity and should only be used as a process control RestrictionsMeasurements of Ionic conductivities donot differentiate between different Ionic species.
