Instead of usig a solidering iron i highly suggest getting access to a hot air station. i soldered smd before but never this small.
Hats off to ANYONE soldering these, thats serious skill. im using my hot air station on them

May i ask what's the safe temperature setting when soldering these using hot air station? I plan to use hot air station as well but i'm not so experienced on this stuff yet..
I saw someone saying above that he used the lowest setting on his hot air station, and that it still blew some other parts almost off
