I assemble surface mount boards all the time, I initially used a variable
rtemp solder station set at about 600 to 650 deg F with the appropriate
sized solder and tip! A little practice is all you need, it looks harder
than it really is! If you are going to do a lot of it, PACE inc. is a
great source for SMT soldering and rework stations. I have the top of the
line station, it costs about 3000 with some accessories, and I feel that
it is worth every cent. But if you only occasionally rework / assemble smt
boards, it would be hard to justify the cost! Any more questions, feel
free to EMAIL me, I can give you lots of info and tips on the subject if
you like.
