Basic principles of temperature setting of soldering station
Under the premise of not affecting the welding quality and welding speed, the lower the welding setting temperature, the better.
Key considerations:
melting point of solder
PCB board time curve
Component heat resistance temperature time curve
Productivity
Adhesive heat resistance temperature curve for pad and PCB connection
Setting method:
Based on experience, set a starting soldering temperature. Lead soldering 350°C, lead-free soldering: 370°C
Fine-tuning 5°C downward or upward, the operator feels its welding speed.
Repeat the second action repeatedly, you will find a working point: after changing the point, adjust the temperature, the operator will not feel anything
This point is the optimum soldering temperature
The correct setting of the temperature of the soldering station not only has a great impact on the quality of the solder joints, but also has a major impact on the life of the soldering iron tip.
