: hey there,
: it's no problem to solder smds on your own. just look for a small "pointing" soldering tip and thin solder. it is important that also the soldering tip gets hot enough, but mostly this is ok.
This works. I hav everified this myself.
The small tip method is one soldering method used also by professionals (mostly in repair business).
Electronics manufacturing houses nowadays can use soldering paste plus a special soldering oven. Some people have even attempted to build one themselves:
'Have you seen my new soldering Iron?'

I have not tried this myself.
When desoldering SMD component a hot air pencil is very useful. Working with SMT is quite difficult without an smt hot air pencil.
Hot air pencil can desolder SMD components easily. And you can also do soldering with paste and hot air. There is even plans to build your own device for this at:
SMT Desoldering Station

This kind of idea really works. I used somewhat different construction myself, but got something working. The model I have I think should be somewhat more powerful than it now is...
: perhaps you need a magnifying glass if you're dealing with small sizes of smds (there are different sizes, i once handled 0402 smds which are quite "unrecognizable" without a magnifing glass. take care of good light.
A goof magnifying glass with light or even a stereo microscope are very good tolls in SMD working.
