SMT soldering was stamp for 3 trolling motors, which motor controller
Archiver

The class lab provide Metcal soldering stations. That's basically a regular
soldering iron with a very good temperature control system and a large
variety of tips made for each type of package. Generally we just used the
very fine round tip and heated one lead at a time. You can find these on
E-Bay for fair prices.
I have purchased a hot air system for myself. This is really the way to go,
but you either need to have a business justification or a really cool toy
budget. A refurbished system set me back over $2500. These systems let you
produce solder joints that look like they came out of a reflow oven. They
also greatly increase your opportunity to remove/replace without overcooking
either the component or the PCB. Drool at: www.zephyrtronics.com. Most of
the major soldering station companies make competitive products.
Its possible to make functional soldering joints using a standard, fine
tipped soldering iron. This just gives you less room for error and you
won't get that smooth commercial appearance.
I've been soldering as a hobbyist for over thirty years -- starting with
vacuum tubes. I was amazed at how much I learned in class. I encourage
everyone to explore their community college catalog for electronics
technology classes. I've been very pleasantly surprised by the high quality
of the instructors in the classes I have been taking for the last few years.
I've been hooked so hard that I've started taking "real" engineering classes
working toward an ME/EE.

I'm curious as to what soldering iron (assuming that you use an iron)
you use to solder surface mount stuff?
