Real-time of nitrogen concentration, PID closed-loop adjust nitrogen flow to achieve the stable PPM value and save the nitrogen consumption
● Increase Solder Stability:
By nitrogen protecting in order to improve the wetting of wave infiltration and enhance solder penetration rate to make sure the stability of quality.
● Reduce Solder Defect:
The tunnel-based entire nitrogen wave soldering can reduce solder defect and improve production efficiency with less oxygen content.
● Save Cost:
The closed preheating environment can reduce the power and the production of solder dross.
