If you decide to solder, the golden rules are:
1) Don't burn yourself. It's kind of obvious, but that iron really does get hot. Be careful with it.
2) Get things as clean as you can without damaging them. Dirt and residue (including the kinds you can't see) can keep a joint from forming securely.
3) Use the right tool for the job. If you're soldering a wire to a surface-mount device, don't use a 5mm wedge tip. If you're doing electronics work, don't use acid core solder or a high-power soldering gun.
4) When soldering on a PCB, don't apply much force to the area you're heating; the glue used to attach the copper to the substrate can melt at soldering temperatures, and you're in for some work (or a screwed Saturn) should you nudge a pad out of place. This isn't as likely to happen if you're using an iron with a reasonable power level (see rule #3).
5) Don't eat, drink, rub your eyes, chew on your fingernails, etc. when soldering, and wash up when you're done. While soldering is not a life-threatening activity as such (assuming that you follow rule #1), the chemicals involved do tend to be known toxins, and washing your hands is an easy enough precaution to take.
Hope this helps. |
