How sensitive are ICs to temperature?
I recently replaced a digital signal processor IC (IC:cxd3098aq) Sony made on a PlayStation 2 and while doing so I heated the chip first to remove it, then I re-balled all the pads and then put the new chip on the pads applied some flux in the form of paste and then heated the chip again with the heat gun to melt the solder.
When I then checked the pins I noticed that not all of them were soldered right so I heated the chip again with the heat gun and also used the soldering iron to fix the remaining pins. And now I'm getting a strange noise zummiiing when I turn the PlayStation on and also the DVD drive doesn't work right.

- How sensitive are ICs to what I've done?
- I've read somewhere that even static electricity can kill an IC so I assume that they are very sensitive to current and so even the smallest solder bridge across two pins can melt it, is this true? but that ICs are much more tolerant to heat??
- The flux I used was in the form of paste. And I got it smeared all underneath the chip, are those paste fluxes usually conductive?
