Tips of how to make the perfect solder joint

1. All parts must be clean and free from dirt and grease.
   
2. Try to secure the work firmly.
   
3. "Tin" the iron tip with a small amount of solder. Do this immediately, with new tips being used for the first time.
   
4. Clean the tip of the hot soldering iron on a damp sponge.
   
5. Many people then add a tiny amount of fresh solder to the cleansed tip.
   
6. Heat all parts of the joint with the iron for under a second or so.
   
7. Continue heating, then apply sufficient solder only, to form an adequate joint.
   
8. Remove and return the iron safely to its stand.
   
9. It only takes two or three seconds at most, to solder the average p.c.b. joint.
   
10. Do not move parts until the solder has cooled.
