Summary
This video explains why and how to tin a soldering iron tip to maintain its performance.
Highlights
Identifying a Deteriorated Soldering Tip00:00:05
A soldering iron tip may show signs of deterioration, such as poor solder adhesion, black spots, discoloration, or a rusty appearance, indicating the tin coating is degrading.
The Purpose of Tinning00:00:17
When the tin coating deteriorates, the tip needs to be refreshed by tinning. This process involves breaking down the oxide coating that forms on the tip.
Materials for Tip Tinning00:00:30
A block of sal ammoniac is used, which generates ammonia vapors to disintegrate oxide layers and allow for tin reapplication to the tip.
The Tinning Process00:00:42
Heat the sal ammoniac block until it generates vapors. Then, flow solder onto the tip to remove any formed oxides. Finally, wipe the iron on a wet sponge.
Result of Tinning00:01:05
After tinning, the soldering iron tip will be clean, shiny, and ready for effective soldering.
