Frequently Asked Questions About Lead-Free Hand Soldering (Part 2 of 4)
QUESTION: What changes are necessary in soldering tool maintenance when working with lead-free solder?
ANSWER: One of the biggest challenges when working with lead-free solder is proper maintenance of the solder tools. High percentages of the tin in the lead-free alloys will have a harmful effect on the tools. Iron tips and solder pots will degrade at a faster rate which will affect the thermal transfer capability. Some equipment will have to be replaced and more attention given to maintaining the quality of the soldering iron tips.
Operator training in using the correct methods will pay huge dividends. Operators should immediately develop the habit of tinning the tip after the soldering operation as well as using distilled water for solder sponges. Tip tinners and polishing bars may be used as a regular part of iron maintenance.
