Obviously, I should clarify.....the 5DX will not identify these cracks during normal testing and call them out as failures. Using the machine in real-time and knowing what area of balls to look in is where this occurs. I found anomalies that leaned toward solder joint cracking. Using the image capture, and, ultimately, replacing the suspect BGA fixed the board and returned it to service. It should be noted that the main problem occured during testing and placing pressure on the suspect BGA made it pass and releasing let if fail.

The only X-ray system I found that could show some cracks is the Uni-Hite XVA-160.
