The selection principle of electric soldering iron
① The shape of the soldering iron tip should adapt to the surface requirements of the weldment and the assembly density of the product.
② The temperature of the tip of the soldering iron tip should be compatible with the melting point of the solder, which is generally 30-80°C higher than the melting point of the solder (excluding the temperature drop when the soldering iron tip touches the soldering point).
③ The heat capacity of the soldering iron should be appropriate. The temperature recovery time of the soldering iron tip should be adapted to the requirements of the surface of the weldment.
The temperature recovery time refers to the time required for the temperature at the tip of the soldering iron tip to return to the highest temperature after the temperature of the tip of the soldering iron decreases due to heat loss during the soldering cycle.
It is related to the power of the electric soldering iron, heat capacity, and the shape and length of the soldering iron tip.
