Actually, it's not SMD components in particular. The failure mode for many MOSFETs and other semiconductor devices tends to be a short. They only tend to fail open if there was enough energy at hand to blow the short clear.
They result when you attempt to violate Ohm's Law.
You can generally diagnose those olfactorily as well as visually. :)
Indeed, my electronics engineering mentor described it as "letting the magic smoke escape". Once the smoke is gone, so is the magic.
It would work again!
FTFY ;-)
Unfortunately, in really old houses, I have seen pennies used. Shudder
