We use a NC Flux in the wave solder and after aAcelerated Life Test cicle we found contamination white residues paths between some solder points. Does somebody know a possible cause for this contamination.

Ideally first you need to analyze the residue to see what it is. We had a customer with white residues after wave and elemental analysis revealed tin.
