Exactly. And machines of that era had a lot of problems (I have
reflowed two early PS/3's a total of three times, and a MacBook) as
manufacturers climbed the learning curve. The Microsoft XBox 360 "Red
Ring of Death" was another instance. This method is not limited to "vintage"
components.
My MacBook Pro 2011 fails dues to its (famous) problem with the discrete
AMD GPU connections.?? A reflow restores the laptop, but inevitably I
have repeat the process every few months. Depending on who you believe,
the fault is with the A) poor thermal design, b) BGA solder used or C)
bumps on the AMD GPU itself.? The reflow is easy enough to do, but
disconnecting the very fragile cables to remove the motherboard is not
for everyone. Using an inexpensive infrared thermometer improves the the
process.

And of course, the solder is Pb-free...
