Stupid. My first post should have been this one. Well, its better later than never, so here it goes.
1. Wash your hands. It's really important, as your hands must be fat-free, or your components might get some of fat on them and the solder wont stick to them.
2. Clean your table. Make sure there's nothing that can make a static discharge.
3. Put a sheet of paper on the table. It really helps, as you can see small parts easier, and lighter background is better.
4. Lights up! Make sure that the area where you are soldering is light enough, or else it will be hard on your eyes.
5. Goggles, or at least eyeglass. Small quantities of flux sometimes jumps off your soldering iron, and it can hit you in the eye. On other areas it wont be dangerous, because when it reaches your face it isn't that hot, but on your eyes that can be pretty bad nonetheless.
6. NEVER TOUCH a hot soldering iron! The temperature of the tip can be more than 300 degrees Celsius, which can cause serious injuries.
7. ALWAYS put your soldering iron into it's stove. Don't leave it on table even for a second. It should be either in your arm when soldering, or in the stove at all other times. If you don't have a stove, go and buy one, its less than 2$, but can save you weeks of hospitality.
8. Make sure that hot soldering iron/stove has no contact with the cable. It can cause shock, and 240V isn't good for your health. Use of heat-resistant cable to avoid problems!
9. Preheat your soldering iron.
10. Clean the tip of the soldering iron with wet sponge, or even better with metal sponge.
11. Mount component that you want to solder into the holes, etc.
12. Work with that component until it is done, before moving to other parts. Rule of thumb: Big components are soldered first.
To solder correctly, first you must add the soldering iron to the component and the place where it will be, and heat those two items at the same time. After a few seconds, add some solder. Then, take solder back, and finally take soldering iron back.
13. Make sure that you solder it good:
14. Check solder places again. They should have a nice volcano shape, not a bubble, not a puddle. The solder should be shiny.
15. Don't be afraid of the fumes: its not lead fumes, it comes from flux. Lead evaporates in higher temperatures.
16. Clean the tip again
17. Start working on another component.
18. When you finish, clean the tip of the soldering iron, but leave a small layer of solder on it - this prevents oxidization, and the tip is preserver for longer time.
This should be it. If you have questions, there's comment field below ;)
