Dear it's not easy and it's not difficult.
just use ur concentration
i had made double ic
this is the procejure
-remove 1st ic and then remove 2nd ic and clean board from solder
- then also clean ic ball from solder and 2nd ic also clean from solder both side
be sure that both ic and board clean from solder and no balls remain on component
then take ic plate with BGA paste
and make re-ball on both ic through ic plate.
remember that don't make re-ball on 2nd ic upper side because when u put 1st ic on 2nd ic then it can't be proper adjust , same like mother board
only make re-ball on 1st ic and 2nd ic downside.
that's it
if any problem then you can reply here.
