What are the reasons for the failure of the soldering iron tip?
1) The newly purchased soldering iron tip is used directly without trimming, resulting in no tinning on the soldering iron tip.
2) The tip of the soldering iron that has been used for a long time is not tinned. It's burnt to death and needs to be trimmed.
In order to prevent the soldering iron tip from failing, the following points should be paid attention to when using it:
1) Newly purchased soldering iron tips must be trimmed before use. Ordinary pure copper soldering iron tips and longevity soldering iron tips have different trimming methods, so you need to pay attention.
2) When the soldering iron tip is not in use, it is necessary to plate the soldering iron tip with solder, which is usually referred to as placing it with tin. Putting it with tin can prevent the surface of the soldering iron tip from being oxidized, and also reduce the volatilization of the copper soldering iron tip coating.
3) During use, it is forbidden to hit the table with the tip of the soldering iron to avoid damage to the tip of the soldering iron.
4) It is forbidden to use files or sandpaper to polish the long-life soldering iron tip, but to wipe it with a rag or a wet fiber sponge.
