depends on your soldering skills?
The best way i find is to prop the box on an angle so you can get a ball of good quality solder on the top pin of the atmel then drag it down the pins slowly resoldering them if any get joined then you get a very fine tip on your iron clean it off then draw the joined solder from the legs to the iron.
You must use good quality fluxed solder though its so much easyer....

i think my iron is a bit too big to do this, can someone recommend the appropriate soldering iron to do the job?

I know this is not quite what your asking but a high powered hair dryer pointed at the atmel can work a treat. Not as good as properly resoldering them but a hell of alot easier if you are unsure.

apply liquid flux to the reflowing object u want to do

use a heatgun / or solder pro

but anything with heat blowing out

and heat it unitl the flux evaporates and solder melts

dont move it

let it cool down

and there u reflowed ur atmels

easiest way in my opinion

first one i did was with some fluxite paste and a paint stripping gun on low setting....i no it was a bit severe but i classed the box a scrap so nothing to lose....a bit rough but it worked...got a rework now.. a hell of a lot easier.....

I expect everyone who can lift & replace or reflow atmels has their own method - personally I have stopped using hot air altogether, i just do it with a soldering iron using the 'bridge solder' method, i.e. flood the legs with solder so all legs are bridged then remove the excess with solder wick. Gives a very neat result and 100% reliable.

Have never used this method will give it a go next time needs be. I use a fine point soldering iron and heat each leg in turn and apply a minute amount of solder to each leg, then use a knife blade to sort out any bridged legs.
