Generally, the materials of soldering tip are iron, nickel, chromium, tin. The key determinant of the quality is iron plating. While under high temperature, the iron and tin will generate a new alloy, this alloy can be melted in liquid solder, and then lead to iron plating lose; in the end, the soldering tip be perforated. The lead can resist the run off speed of iron plating. Moreover, the higher tin content of the lead-free solder, the corrosive degree will be more serious; the higher temperature, the faster corrosive speed. Relying on years of research, we discovered that when the soldering tip is plated with the special electroplate formula, the corrosive speed can be slowed down efficiently. Coping with lead-free soldering, these tips have longer life and better thermal performance.
