  • I have been ISO certified in soldering for about 4 years now (for my job). I have used wall-socket irons, and production irons, and my advice is to go with the best iron you can afford - temperature-controlled is preferred. Wattage mostly determines how fast the iron will recover after being touched to something cold. For very small parts this is not very important. The thermal mass of the tip itself does the job. For through-hole soldering, ordinary solder by itself works fine. For surface mount parts there is an increasing need to apply flux to the joint before you apply heat, so wetting will be fast and complete. Your "dwell time" (how long you leave the iron touching the connection) becomes important in SMT soldering, so you want the solder to "take" with a minimum application of heat to the joint.

No public wish lists :(
