What's your topside Bd. Temp before hitting the Wave ? Have you done profiling on your machine? What solder alloys you are using (might be due to incompatibility with flux)? Is the IR lamp between pre-heat and Chip wave ON during the operation? Wh

Top side temp. is 97C before the wave. No, we don't have the IR lamp on; we did try it though with no positive change. Solder alloy Multicore 63/37 Other boards run better. This one is the worse. We have not had good success eliminating bridges on SM

Yes, you need to conduct X-ray inspection for BGA-SMT assembly, but it doesn't mean 100%. If your process is well capable and robust you can do sampling. There is an available X-ray machine that right now Iam assessing, cause we are going to buy one.
