Hi

I use different method similar to factory method I do
not use solder or iron I use water soluble solder paste
and sharp nose heat gun.

1. I put little amount of glue in center of the foot print to hold the
part     then I align the part

2. I apply solder paste with small brash that way I do not put too much
3. I use heat gun after about a minute or so solder pate turns in to
real
    solder
4. I apply water soluble liquid flux and I reheat just to be sure about
   connections
5. I wash the board with de ionized water
6. I use heat gun on low temp to dry the board.

I never had any problem and the result is excellent.

My tips: iron and solder are not that important, a good magnifying glass
and de-soldering braid are essential.
