>the plastic connectors are very susceptible to melting if brought outside their fairly narrow soldering range so do your research.
Right. That's what I suspected and why I asked the question. They're so fucking small so there's no chance in hell that I'd be able to desolder them and then solder them back in after the reflow. So oven's a no-go.

>Find a place that does cell phone repair and can reflow solder BGA's. Bring them the PCB. Done.
That is an option. I'll ask around but this type of work isn't cheap. I can buy from China a replacement mobo for $200 that's guaranteed to work. If reflowing is gonna cost me $150, with no guarantee of success, I'd probably pay the extra $50 to be sure.

>They must have used bismuth solder on one side.
Not sure what they used. But after this happened to me, I did a lot of research and reading and it seems to be a common issue.

>if you know the approximate outlet temperature of the heat gun and can guesstimate about how far to back off to get a reasonable heating profile
Heat gun that I have is 1500Watts and has an 1" nozzle. That sounds like an overkill and it seems to be way too powerful and would destroy the board/IC.

I've been searching chinese websites and came across pic related. It's 300W which sounds a lot more reasonable. What do you think I buy one of these, isolate the IC in question with some aluminum foll shroud/cone and heat it?

I have no idea how long I should heat the IC for... any guesstimates, anyone?

Anyway, I truly appreciate you guys reading and throwing in your 2cents!

>You could be the hero of the Canon DSLR community
I hear you. It's a ridiculous situation and the only solutions right now are to pay $200 for a mobo or pay $350+ to Canon. Both of these solutions fucking suck!
