Core Advantages
- Ultra-High Purity & Welding Performance
- Suppresses solder oxidation, enhances wetting speed, and reduces defects (e.g., solder balls, bridging).
- Ensures consistent weld quality for lead-free processes.
- Flexible & Controllable Output
- Nitrogen concentration adjustable below 10 ppm.
- Flow rate tailored to specific furnace requirements (5-150 Nm³/hr).
- Cost Efficiency
- Reduces gas costs by ≈50% vs. purchasing bottled/liquid nitrogen.
- Low maintenance, minimal energy consumption.
- Integrated On-Site Production
- Nitrogen generated on-demand, eliminating logistics delays and storage risks.
- Compact footprint, plug-and-play operation.
Application in Selective Wave Soldering
- Critical Role: Forms an inert nitrogen blanket over solder waves, preventing oxidation during high-precision PCB assembly.
- Result: Higher first-pass yield, reduced dross formation, and extended solder pot lifespan.
