Some people strongly believe there are conspiracy among hardware
manufacturers, such as planned failure. I'm one of them tinfoil hats,
because I've seen too many "too convenient" failures to believe they
were random.
We now live in the age of Pb-less solder and BGA chips. This is a bad
thing because Tin without Pb becomes brittle with time. Also Tin could
grow microscopic hair-like structures that could short-circuit
neighboring solder joints. This is why service people have to resort to
re-flow and re-ball techniques on still working BGA chipsets,
essentially adding Pb and resolder ICs back into same motherboard or
replacing faulty chips if they are dead.
I've seen flux that becomes conductive after a couple of years of device
usage. I've seen rubber-like substance with same characteristics that
holds components in place inside PSUs, you just stick 2 probes of your
MMT into and it shows resistance.
I can go on infinitely on this topic, so I better stop.
