How long is the lifetime of a soldering iron tip?
There are two ways in which a tip can no longer be used: 1) tip life, and 2) blackening of the wetting area on the tip, which results in solder no longer being wetted (mainly due to oxidation of Fe).
The tip is plated with Fe (iron) all around to prolong its life. The life of a tip is the wear and tear of this plating. The tip becomes thin and loses its shape (e.g., when the tip is thin), and eventually a hole is formed. In this condition, heat conduction becomes extremely weak and the soldering iron cannot be used.
Tip lifetime is determined by the following three factors.
It is recommended to count the number of soldering cycles and replace the tip in advance at 80-90% of the expected lifetime. This will maintain the quality of the soldering and reduce interruptions in work.
How do I select a tipping point?FAQ – Frequently Asked Questions
Q.Soldering takes a long time. Also, the solder does not melt well.
Does the tip type match the shape of the component, board pattern, and land? If the tip shape is smaller than the size and width of the pad, heat will not be transferred, resulting in slow soldering and failure to produce a good product. Check the tip shape and the temperature setting of the soldering iron.
Q. Solder sticks to the adjacent pattern.
The tip shape may be too large for the component to be connected. This can also be caused by moving the tip excessively during soldering.
Q. Solder does not wet the tip. (It does not stick).
The soldering tip may be oxidized or the tip may have reached the end of its service life. Replace the tip with a new one.
Q. While using the same soldering tip, suddenly stops heat transfer.
The iron tip may have been worn out. Replace it with a new one.
