Why does the tip of the soldering iron always run upwards?
Some customers have reported that the tip of the soldering iron runs up when the soldering iron is in use. What is the reason?
Before answering this question, let everyone understand the structure of the soldering iron head. The soldering iron tip is mainly composed of copper,
iron, nickel, chromium, and tin. Let's first understand the role of various metals.
Copper - As a heat conductor, it is the main component of the soldering iron tip.
Iron - plays an anti-corrosion role and is a key factor affecting the service life of the soldering iron tip.
Nickel - plays the role of anti-rust iron plating.
Chromium - non-stick to tin, preventing tin from running onto the body of the soldering iron tip during use.
Tin - in the head, where the tin is used.
We can understand at a glance that the reason for the tin to run up is related to the chrome plating layer. If the chrome plating layer is too thin, tin will run up. Generally, the tip of the soldering iron needs to be chrome-plated for more than 5 minutes. If the customer's use temperature is too high, the chrome-plating time should be increased. This is closely related to the temperature of the soldering iron tip.
