Address, I'm using a local facility to inspect, via X-ray, 4 BGAs types. Three (3) are PBGA and are easily viewed at 35 Kv. I can not view the 4th package at 35Kv due to the package (basically a heatsink). Is it possible to view through this package if at 90+Kv or does it not matter due to the package? Also, what are standard or the recommended Kv to use when X-raying BGA packages? Please advise.
