Not quite a tutorial, but a excellent link to soldering and splicing components as rocket scientists would have it. (Yep, it's from NASA)

Enjoy:

Some good tips, some typical NASA silliness.

Of course, we need to live in this century too: http://www.infidigm.net/articles/solder/ ;)

I do a lot of surface mount work, and for one-offs those techniques work fine. For small scale production (where you're making more than say 5 or 10 of a given board), use a stencil from Pololu - they are cheap, work great, and allow you to make board after board with very little mess and trouble.

I've liked this video explanation, but have not put it into practice yet :

Yeah, I used that video to solder my board for my Mini-sumo. After a bit of practice, it works great. I managed to solder everything with a 1/32 inch screwdriver tip.

Having soldered thousands of SMT boards in the past this video uses the same technique we use with a few exceptions. We used a different soldering tip which used a flat coined tip at an angle that worked extremely well for all types of soldering from 2225 caps to fine pitch QFPs. The needle point soldering tips tend to overheat, and heat transfer is poor for components with moderate sized pads. We used High temp solders such as SN63, SN96 (My screen name) and HMP solders.

Great video.

Wierd...for some reason I always thought your screen name had something to do with Super Nintendo.

:p

Now see - I think he missed the mark on flooding. I agree that wicking is painful and illadvised. But there's a reason we call it "flood and suck". Using a solder sucker, especially a rework sucker, makes flood-and-sucking those big chips go with almost no effort. It's easy for the novice and you don't really need to _work_ under magnification, using it to check the work afterwards.
