Hey guys
is the part for guide at the Atmel's datasheet for soldering by hot air gun?
for example, How much can i warm(temp) an atmega and for how long?

I always use my hot air gun at 400C and I've had very good results with every part I've soldered (except the BGAs, which give me about 40% yield).

Jeff,

Sounds like your iron is too hot. But at the same time you can have a higher air temperature than iron temperature because convection transfers heat a lot more slowly than conduction.
