The 5DX is hard to miss on the floor provided the floor hasn't collapsed
under its 8000 pound weight. As has been posted by another fine gentleman,
it is an x-ray laminography machine. It is used to initialize first pass BGA
acceptance, primarily.

It also comes into play as a vital tool after replacins BGA parts on PCB's.
Often, especially in a new to BGA operation, ICT test folks tend to point a
skewed eyeball at the BGA's because their solder joints are not
readily/easily visible to "normal" inspection.

X-ray, either laminographic or transmissive, is used mostly to detect
shorting. However, opens may be determined as well in cases where/when
solder is drained off down an adjacent dogbone via hole.

Don't trip on the 5DX or let it fall on you,
