So I ordered that soldering iron Gene recommended. It's not here yet,
but it should be soon.
Anyway, I'm a butcher with a soldering iron, and I figured now that I'm
getting some decent equipment I oughta learn how to do something other
than glob solder all over everything and hope it works! lol. Does anyone
have a good reference, preferably online, on learning to solder well? Or
at least not embarrassingly bad?
Brian

Brian, I have the soldering & wiring bibles for you....
you can find them both here:
http://phoenixcomm.net/~phnx2000/sim/library.shtml
<http://phoenixcomm.net/%7Ephnx2000/sim/library.shtml>
"Soldered Electrical Connections - NASA-STD-8739-3"
"Crimping, Interconnecting Cables, Harnesses, and Wiring. -
NASA-STD-8739-4"
I got my NASA rework cert when I worked for Hughes Aircraft in the 80's
enjoy...
remember only heat (melt) the solder indirectly, and always keep a damp
sponge around to keep your iron clean, like after every joint. Also if
you are soldering connectors (they are a real pain in the ass) a solder
pot is a great investment, so that you can pre-tin your wires..
Keep you work clean,
Enjoy

they go most of it right - but some things are flat out wrong.
1. cut your leads after your board is cooled - a min or two
2. hold your soldering iron at a much higher angle... like 60 degs. or
about 30 deg from vertical.
3. most of what you will be soldering will use a conical or taper tip.
if you need a chisel tip. then you are going to solder a much larger
part...
4. get some solder wick for unsoldering
5. get a solder pull-it vac for unsoldering
6. say away from sandpaper it leave grit on things
7. get a 'pink' eraser its good for cleaning pcbs
8. if one pink eraser is good then two is better mounted in a U shaped
spring steel (beryllium) is good for components.

Some soldering techniques I use:
The old saying "Measure twice, cut once" applies here... Make certain you have all component orientation identified.. Nothing worse than having to unsolder a 40-pin DIP to turn it around.
IC's: Use sockets wherever possible. There's nothing worse than soldering in a 40-pin DIP only to discover you have it in backwards (Not... that I've ever done that......=)
ICs: I soldering the pins like you would tighten the lug nuts on a tire.. Alternating patterns (Pins 1,8... 2,9... 3,10...) Keeps the heat relatively disbursed around the package
Discrete components: If I have a lot of them to solder, I solder one lead on each, completing the set, then return and solder the other lead.
Transistors/Mosfets/Triacs & Diodes, etc: Solder 1 lead, wait about 20-30 seconds, solder another lead, repeat....
Use as fine a soldering tip as possible (I use .03 or something like that)
Get a metal scrub pad for cleaning your tip
Use hard flux to really get the dirt off ( I have a tin of the stuff and it's great for cleaning.. just move the tip around inside the tin until clean) It's like really hard silly putty)
Ground your soldering iron.
Use rubbing alcohol to clean the circuit card after soldering to remove the flux. Left intact, the flux will start to deteriorate the board runs and solder joints.
Soldering wires onto boards: "Tin" the wires first
Large components: (Relays, power transistors...) Solder these in first... it gets all the big-heat items out of the way so your not soldering a huge relay next to a 1n914 diode which is rather sensitive to heat...
SMD ICs: Make a mistake here and forget it. (Order a backup circuit card =) I have a few decades of experience under my soldering belt but SMDs.. unless you have the gear for it.. are really tricky.. They can be done, but it does take some practice.
Speaking of SMDs.. get a shop magnifying lamp and a circuit card holder :-)
Hope that helps!

I agree on the tools, bits and angles comments, Chris.
The guys' technique does leave a bit to be desired. And
yes, I also cut my leads after soldering with good
quality angle nose cutters; but doing this will fail you
on getting "Space-Qualified-Soldering" Certification.
I posted this video link mostly as it gives a basic
understanding as to "why" you solder with flux-cored
solder and what cleaning and tinning is all about, etc.
Most of the rest comes with practice.
Main point is keeping everything clean and applying the
iron and solder to the right points in the right order
'at and for' the right time.

Forgot to add: Cutting leads: I use Nippers.
http://media.digikey.com/photos/Swanstrom%20Photos/S491E.jpg
Reason being is that normal wire cutters have angled cutting surfaces on both sides of the cutting area.. This can translate into mechanical shock into the component. (Especially worrisome with germanium diodes)
The ones shown have a flat outer cutting area with the cutting angle located on the inside surface, so the cutting shock is directed away from the component.

...and never linger more than 2-4 seconds on a component pin :-)
Another neat little trick is to connect a small alligator clamp to the lead. It helps as a heat-sink.

Anyone have a source of _affordably_ priced wire strippers that use teflon
blades?

Nope, I'm referring to strippers that have teflon or other non-metallic
blades. They're used in military & aerospace applications. If you nick a
wire, you have to throw it out.
