Lämmastiku tagasivoolu eelised

Lämmastiku atmosfäär (O₂<500ppm) in reflow ovens reduces oxidation, lowering surface tension for improved wetting. Solder joint void rates decrease from 25% to <5% under nitrogen. Thermal efficiency increases by 15%, allowing peak temperature reduction of 10-15°C. Cost analysis shows ROI within 18 months despite nitrogen generation expenses. Critical for SAC305 alloys prone to dross formation. Closed-loop systems recycle 90% N₂, enhancing sustainability. Automotive applications require nitrogen for void-sensitive power modules.
