Root, thanks for prompt answer.
I bought new chips (I hope that chinese guys will not send me used).
About equipement I use Welder T860 Infra red soldering station combined with AOYUE 857A++ hot air gun. It`s not realy high end:) ...
So you suggest lower temperature and longer time of soldering with preheating of large area of mobo?
