Most likely happening during the cooling phase. I also produce many of these joints with no reliability, DOA, or field failures to date (thousands upon thousands). Contact your paste supplier and they will give you the technical stuff on what you a

Thanks Patrick. I understand your points. It gives us good results. I didn't know about the flux activity on Gold finish. It's a pleasure to get this kind of explanantion.
