Battery soldering iron

A soldering iron is a hand-held soldering tool that uses an electric heating element to heat a metal soldering iron tip to a soldering temperature (usually 200-450℃). It is used to melt solder and connect the pins of electronic components to the pads of the circuit board. Its working principle is based on Joule's law, where an electric current passes through a resistance wire (such as nichrome alloy) to generate heat, and the heat is conducted to raise the temperature of the soldering iron tip. According to the heating method, it can be divided into internal heating type, external heating type, constant temperature type, and lead-free soldering station, etc. It is a basic tool for electronic repair and circuit making.

  •   A soldering iron is a hand-held soldering tool that uses an electric heating element to heat a metal soldering tip to a soldering temperature (typically 200-450℃). It is used to melt solder and connect the leads of electronic components to the pads on a circuit board. Its working principle is based on Joule's law, where an electric current passes through a resistance wire (such as nichrome alloy) to generate heat, which is then transferred to the soldering tip via heat conduction. Based on heating methods, soldering irons can be classified into internal heating, external heating, constant temperature, and lead-free soldering stations, among other types. It is a fundamental tool for electronics repair and circuit making.
