Foornada dib-u-socodka SMToo leh nitrogen (N2) waa doorka ugu muhiimsan ee yaraynta oksaydhka dusha alxanka, hagaajinta qoynta alxanka, sababtoo ah nitrogen waa nooc ka mid ah gaaska aan shaqayn, ma fududa in la soo saaro xeryahooda birta ah, waxay sidoo kale gooyn kartaa oksijiinta hawada. iyo taabashada birta ee heerkulka sare iyo dardargelinta falcelinta oksaydhka.
Marka hore, mabda'a ah in nitrogen ay hagaajin karto weldability SMT waxay ku saleysan tahay xaqiiqda ah in xiisadda dusha sare ee alxanka ee deegaanka nitrogen ay ka yar tahay in ay soo gaarto jawiga jawiga, taas oo hagaajinaysa dareeraha iyo qoyaanka alxanka.
Marka labaad, nitrogen yaraynaysaa milanka ee ogsijiin hawada asalka ah iyo walxaha wasakhayn kara dusha alxanka, si weyn u yaraynaysaa oksaydhka ee alxanka heerkulka sare, gaar ahaan in hagaajinta tayada backwelding dhinaca labaad.
Nitrojiin ma aha dawo u ah oksidaynta PCB.Haddii dusha sare ee qayb ka mid ah ama guddiga wareegga uu si aad ah oksaydhized, nitrogen soo celin maayo nolosha, iyo nitrogen kaliya waxtar u leh oksidation yar.
Faa'iidooyinkaalxanka foornada dib u soo celintaoo leh nitrogen:
Iska yaree oksidation foornada
Hagaajinta awoodda alxanka
Kor u qaadida alxanka
Iska yaree heerka daloolka.Sababtoo ah koollada alxanka ama oksaydheynta suufka alxanka ayaa la dhimay, socodka alxanka ayaa ka fiican.
Khasaaraha ka mid ahMashiinka alxanka SMToo leh nitrogen:
gubi
Waxay kordhisaa fursadda jiilka qabriga
Awood la xoojiyey (saamaynta wick)
