You can "solder" BGA chips quite easily with a hot-air blower:
put the chip into the approximate position, then heat it with
the blower. When the solder melts, the chip will align itself
automatically. Then very carefully remove the blower, i.e.
increase the blowing distance so that the chip remains aligned.

A normal hot-air blower for hair probably doesn't have enough
power for this though..
