Real time x-ray inspection of "pillow open" solder defects in BGA. Pause the video at the 0:28 mark....can you find the five open solder joints? Hint: they are perfectly round solder balls overlapping a round mound of solder on the pad. You can see an overlap where the bond should be, it's shaped like a marquise cut diamond. "Pillow opens" are so named because they look like a head on a pillow.
