Follow these basic rules to maximize your soldering skills and effectiveness:
1) Clean Your Tip! ...then clean it again. :)
2) Heat your target and count to 5 before applying solder;
3) Remember...You aren't trying to melt the solder directly, you are trying to get the solder to melt on the joint;
4) Less (solder) is More;
5) Avoid cold solder joints;
I teach a basic soldering for electronics class and I can't stress these points enough. Even if you are sure handed and experienced in soldering technique, not observing these simple rules will prevent even the most skilled makers from achieving strong, effective and long lived solder joints.
1. Cleaning your tip ensures maximum efficiency of heat transfer and reduces impurities introduced into the solder joint, making the solder flow more easily
2. Once you begin heating the target area, wait 3-5 seconds before applying solder
3. Do not apply the solder directly to the tip (the first instinct of the uninitiated), rather heat the target first, then apply solder to the target
4. Slowly and judiciously apply solder until the pad and lead are both sufficiently covered, AVOID large blobs of solder as they can cross traces and short out your circuit
5) "Cold" solder joints are the result of joints not being fully stationary before they cool and harden, this is usually indicated by a matte grey appearance of a cold solder joint vs, a shiny silver appearance of a proper solder joint
Of course as you develop your technique and skill, you'll find these words are easier said than done. If you are finding you are having a particularly difficult solder joint, make sure you are observing these tips.
