Chris Halliwell knows what they are doing. If you don't have a hot air station, decent soldering station and surface mount soldering experience plus the sundries ie solder paste, good tweezers, good lighting, magnify glass as a minimum then don't even try.

Surface Mount soldering around temperature sensitive components is a risky game unless you are aware of the processes involved. Even then it only takes a few extra degrees in temperature to melt and fry surrounding part's.
