In and out!
Which makes sense. My guess is in the 80's 90's they would send the board back to
a rework facility and repair it there. BGA/PGA is not too difficult to do if you have a
good rework station, and the rest of the chips on the board were probably worth enough to
make the rework totally feasable.
By the mid 2000's, yeah they probably would just trash the board.
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.
