whats the type of paset and the type of profile you're running. Doesn't look like enough heat to me on the first set of pics I see. Are you running ROHS BGAs on a lead profile?

Nothing wrong with using RoHS BGAs except that the spheres won't melt/collapse at normal leaded reflow temps. Reliability will questionable. Some people use a hybrid profile with a slightly higher temp (~230C)and a slightly longer TAL (60 -90 sec).

Since 2006 RoHS requirements have required lead free solders to take the place of tin-lead solders in electronics. The problem is that in some environments the lead free solders are less reliable than the older tin-lead solders. One of the ways to solve this problem is to corner stake, edge bond or underfill the components. When considering what mitigation technique and material to use, the operating conditions must be characterized. The temperature range is important when selecting a material to use since the glass transition temperature (Tg) and coefficient of thermal expansion (CTE) are important properties. If improperly chosen, the mitigation material can cause more failures than an unmitigated component.
