From what I have read this is really quite safe. When they make computer components the lead solder is put on the card in a paste form apparently and then the board is put in the oven to flow the solder. So this is basically reflowing the solder. The boiling point of lead is something like 2000 Kelvin so there are no real fumes, because the only thing melting is the solder. Not only does this fix hairline cracks it also melts any whiskers
that could bridging connections that should not be bridged.
Although from what I have read people have just recently started doing this, but it doesn't seem like a permanent fix. People have had their cards go bad again in as little as two weeks, but some are still working after a couple months.
