|Point 1||Solder corrodes the iron-plated part and makes a hole.|
|Point 2||The solder-plated part is oxidized in black and the tip is no longer wet with solder.|
|Point 3||The surface of the heating element insertion part oxidizes and the heat conduction becomes poor.|
(*Except for tips in composite type which has different structure)
Point 2. The solder-plated part is oxidized in black and the tip is no longer wet with solder.
The iron plating beneath the solder-plated part becomes exposed, and the area becomes black as oxidization starts. This is especially common when using lead-free solder, or the soldering iron is used without applying solder in the rework for solder bridge or other process.
