To the best of my knowledge, this is wrong in the case of Apple
computer.  Board swaps are done simply because it is faster to stock
and install working replacements, than to keep the machine down while
some yahoo plays with the circuit board.

I believe apple has technicians to do repairs at a national, central
facility, with advanced diagnosis tools.  Repaired boards on day live
again in other macintoshes.  Most mainframe makers follow the same
policies, because it is too wasteful not too.
