Hi
That depends on the xray machine you are talking about.
The ones we use in industry can see a single unsoldered pin
on one of those C4 packages. I'm sure that is more than
enough resolution for a PC board.

An x-ray won't work very well. The resolution isn't high enough, and the
image will look fuzzy. It also won't work at all for double sided boards,
which I think are what the Apple I uses.
