We are having intermittent faults with BGA's soldered onto an immersion gold finish board with snpb solder. One potential cause I have been informed is the formation of phosphorus crystals. As I am not an expert in this area I have no idea if this is correct or not. Can anyone point me in the direction of any literature on this subject or offer advice on how to resolve this crystal formation.
