Nice video! I tried but failed to mount a BGA chip properly, probably due to the GND layers which dissipate heat fast. Which assembler did you pick? I quoted around but the prices are always several hundred $$$ for a single chip...
+Alex Lau Yea I'd like to figure out how to mount my own BGA as well. The quotes I get for mounting a single chip are like $500 or some crazy number. The problem is testing this thing out involves destroying a sh&tload of good chips before perfecting the method.
I've never tried reballing a BGA, Miguel, but from what I've seen, I don't think this method would work. Reballing with something like my heat gun would just blow the solderballs all over the place. I think you also need a template/stencil to keep the balls from rolling around as they're heated. Check out some of the reballing videos. If you find a way to do it, let me know! I have a bunch of FPGAs that need reballing and it's not worth the money I'd pay to do it.
+Miguel Rosa Do you really need to reball or just to reflow the chip? For Reflowing you need good liquid flux and the hot air gun. For multilayer cards with several power planes it is very helpful to preheat the board to something like 125°C for some minutes. The components will tolerate this. Of course plastic parts like fans and cables should be removed as far as possible.
Is it ok to use a heat gun such as this to disassemble some components? Or should I get one of the fancy adjustable ones?

Is the goggles a safety one or magnifier - any links if its magnifier
Do you think this is applicable for example to reball a graphics card or something like that?
