Dec 10, 2011 at 22:43 comment added AndrejaKo @Kevin Vermeer♦ A quick search gave me a comment on this question and this article. I actually heard the anecdote on this site for the first time and I'm pretty sure that I've heard it more than once but I can't find the post where I read it for the first time at this time. I do know that in that post, the component was a resistor.
Dec 10, 2011 at 19:01 comment added Chris Stratton @KevinVermeer Don't dismiss such anecdotes out of hand. I've seen SMT diodes floating on molten solder due to a PCB internal short. Obviously they were still conducting; I don't know for a fact but would be inclined to suspect they still functioned as diodes at least when cool. Components on prototypes routinely survive all sorts of non-production assembly and re-work that easily exceeds the standard "10 seconds at 300C" type data sheet spec. There's a big difference between what something is rated to tolerate, and what it can often survive while remaining somewhat functional.
Dec 10, 2011 at 18:26 comment added Kevin Vermeer > There are stories of SMD resistors for example desoldering themselves because they heat up too much - I've never heard of this. Most graphics cards will use lead-free solder, and that's soldered at over 200°C, or almost 400°F. There's no way that a hot graphics chip or capacitor could even approach that temperature and still have a chance of functioning.
Dec 9, 2011 at 18:04 comment added darron I agree with this. There's no way that's from a volume production line. Someone tried to either fix or enhance it, and failed.
