Full-Tunnel Entire Nitrogen Wave Soldering System

　　Nitrogen Closed-loop Control

　　A real-time monitring on nitrogen concentration and PID closed-loop adjusting nitrogen flow to realize the stable PPM value.

　　Increase Solder Stability.

　　By nitrogen protecting can improve the wetting of wave infiltration and promote solder penetration rate to make sure the stabie quality

　　Reduce Solder Defect

　　The tunnel-based entire nitrogen wave soldering can reduce solder defect and improve production fficiency with less oxygen content.

　　Save Cost

　　The equipment maintenance cost could be decreased effectively by a closed preheating environment.
