SMT dusík reflow

Nitrogen atmospheres (O₂ < 1000ppm) reduce solder oxidation, improving wetting. Inert environments permit lower peak temperatures, saving energy. Nitrogen generators (PSA or membrane type) supply gas cost-effectively. Closed-loop systems recycle nitrogen, enhancing sustainability. Benefits include Méně mezí v BGA kloubech a Shinier pájecích površích . Mezi výzev patří monitorování čistoty plynu a prevence úniku .
