This is really not that we should do in the kitchen, but if needed BGA's can be soldered easily with any heat source:
The magic is really in the flux. Any other BGA is easier than this one, to get this right you really need to have alignment precison below 200 microns. The BGA will self align itself but this tiny thing still has to be placed very accuratly.
We tried 3 times, first time the BGA was soldered perfectly but 180 degrees wrong, the second one was possible also perfect soldering, but I did drop it, and as it was still hot the BGA did come off.
The 3r one I did bake too short, so it did not stick, so she had to place it 4th time, and well the solder was OK and the board actually works.
All normal BGA packages are easy to handle - do not be afraid - 0.8 and 0.5 aligne itself much better than this small thingie..
