I remember a rework/repair facility in our company around 2005 or so. I'm not
sure how long it lasted after that.
As for rework stations, I have one, inherited from a disk drive company that
closed in 2001. "BGA 3000". I think all it needs is a camera, which I once
had but I think let someone borrow and it disappeared. That's part of a system
to do accurate positioning of surface mount chips onto the board. I wonder if
a GoPro or the like could be put into service for that task.
