Full Description

This Material and Process Characterization/Qualification Test records changes in Surface Insulation Resistance (SIR) on a representative sample of a printed circuit assembly (PCA). It quantifies any deleterious effects that might arise from solder flux or other process residues left on external surfaces after soldering, which can cause unwanted electro-chemical reactions that grossly affect reliability.
