How Clean is Clean

Final Report of NCMS Project No. 171003 (June 1998)

The mandated elimination of all chlorofluorocarbon (CFC) cleaning agents prompted the participants of the Definition and Measurement of Cleanliness project to explore the relationship between assembly residues and electrical performance. Participants quantified the residues from assembly processes that included low-residue flux/no cleaning and water-soluble flux/aqueous cleaning. The effects of the residues on electrical performance were assessed. New analytical procedures were investigated and developed. The interaction between flux chemistry and the soldering process and process variables were evaluated. These evaluations were shared with the electronics community through technical publications and conference presentations. This 504-page project final report presents these results as a compilation of technical documents.
