That is really informative -- and I could have used it over the weekend....

And then there is this guy, TOTALLY different technique. video.google.com/videoplay?docid=-4537972975721124263&q=professional+smt+soldering&total=3&start=0&num=10&so=0&type=search&plindex=1

Bit of an awkward video.
I noticed that they use a wedge solder tip to distribute the heat.
They sure make it look easy.

It really is easy when you have done it enough. It is very hard at the beginning, but as you get better, it gets easier. Its like riding a bike. If you have learned it, it is easy [noparse];)[/noparse]

Nice Videos Thanks!

I have done both techniques and yes it is an art! I hadn't done any soldering for a while when I got into surface mount and it didn't take me long to figure out the correct way because the wrong way wasn't working. Flux and solderwick is definately your friend!

Water soluble flux in paste or liquid form seems to be a big advantage as you need lots of flux and easy clean up of the tiny parts. Tacking down parts that have more than two leads seems to work for me. I just try to get two diagonally opposite leads to hold the position. If I am wrong, it is easier to reposition. And, if the board already has enough solder on it, you are free to focus on getting proper flow with each connection.

Videos have a way of making everything look easy. Just try to make a wedding cake from a video and you will see what I mean. It is just as important to select a project that is not too demanding as it is to having one that is interesting. I'd try baking an apple pie first, then slowly move up.

The SXes and the Propeller are ideally suited for such smaller projects as they are so adaptable by reprograming. If you use Eagle to get a good circuit board image, it can evolve and easily be modified to include the kind of i/o that the situation requires. And, it is relatively easy to stay to one-sided, homemade printed circuit boards.

The only real catch is if you choose to use expensive reflow solder paste to do assembly. The stuff must be refrigerated and if you cannot buy from a local supplier, it has to be air frieghted in a cold pack. It all gets quite silly. So with small projects, you can first just tin your board with conventional solder, liberally lux, and then attach components by reflow.
