Learning how to solder SMD boards

I'm always trying to improve my skills and have recently started learning how to solder teeny tiny SMD parts onto boards. I think that since new machines are starting to ship with more and more SMD boards I should probably try and figure this stuff out. I'd rather repair a board then throw it away and some of these boards will probably be fairly expensive. I cringe at the thought of needing to replace the large Playfield PCB's in MMr and AFMr because of a dead LED.

So I've started buying these cheap diy electronic kits. There fun to build, I even had my daughter (6yr) excited to be helping with sorting parts, learning their names and watching me solder. I've made a couple kits, but so far they've been fairly simple. I've built this cheap oscilloscope

My next kit will be

Does any one have soldering tips to share? Any diy Kits you'd recommend?

So far with my little knowledge I've found what works for me. To install a SMD part I'll put a drop of solder on one of the PCB pads, use tweezers and place the part onto the one pad, then once in place I'll solder the other side. Same with a small IC, I'll solder one leg on each side to get it lined up and then go back to finish it off.

Seems pretty easy, I just like the practice now, before it's needed on an important fix.

Here's some general info.

Personally I would invest in a hot air rework station. Even a fairly inexpensive one will give better results than a soldering iron.

If you are serious, I suggest "go real", not DIY hobbyist route.
You will learn more, and get better results.
You will also be guided along the way for proper equipment.
There are WAY too many amateurs doing work they should not be touching.

Look for colleges that offer IPC certifications such as this one:

(College of Electronics Manufacturing)

Pay attention to the program details that are shown, and the specific nature of courses, and their levels of certification, as they are not all the same. Some colleges (essentially trade schools) only offer individual course, some trainer, some both.

You will not get the same level of hands on training in community colleges, nor is designed to provide an associates in IT type technology.
These are the wrong skill sets, and the advisors are not going to know what you are trying to accomplish, and point you in the wrong direction.

Best of fortune.
