The present paper summarizes the second part of a study dedicated to the extraction of the ionic contamination from unpopulated circuit board and electronic assemblies with low-standoff components. After investigating the influence of time, temperature and IPA/DI-water mixture on ion extraction in ion chromatography [1], the second part focuses on the evaluation of the ionic cleanliness of unpopulated boards and on a comparison of ion chromatography results between intact electronic assemblies and assemblies after removal of low-standoff components.
