6.4 Process Validation

Prior to production, the adequacy of the cleaning process should be verified via ion chromatography.

In general, aqueous cleaning processes should be regularly monitored to assure that they are performing as expected. Incomplete removal of water-washable flux residues can cause electromigration, dendritic growth, and ultimate failure of the circuit assemblies while in service.
