Embindini we-1990s, kwakukho umkhwa wokutshintshela kwi-infrared + ukufudumeza komoya oshushu kwi-reflow soldering eJapan.Ifudunyezwa yimitha ye-infrared engama-30% kunye ne-70% yomoya oshushu njengothwala ubushushu.I-oven ye-infrared hot reflow oven idibanisa ngokufanelekileyo izibonelelo ze-infrared reflow kunye nokunyanzeliswa kwe-convection yomoya oshushu, kwaye yindlela efanelekileyo yokufudumeza kwinkulungwane yama-21.Isebenzisa ngokupheleleyo iimpawu zokungena olomeleleyo lwemitha ye-infrared, ukusebenza kakuhle kwe-thermal kunye nokonga amandla, kwaye kwangaxeshanye yoyisa ngokufanelekileyo umahluko wobushushu kunye nefuthe lokukhusela le-infrared reflow soldering, kwaye yenza i-solder eshushu yokuqukuqela komoya.
Olu hlobo lwei-reflow solderingi-furnace isekelwe kwisithando somlilo se-IR kwaye yongeza umoya oshushu ukwenza iqondo lokushisa kwisithando somlilo lifane ngakumbi.Ubushushu obufunxwa ngezinto ezahlukeneyo kunye nemibala yahlukile, oko kukuthi, ixabiso le-Q lihlukile, kwaye ukunyuka kweqondo lokushisa okubangelwa yi-AT kukwahlukile.Ngokomzekelo, iphakheji ye-SMD efana ne-lC i-phenolic emnyama okanye i-epoxy, kwaye i-lead yintsimbi emhlophe.Xa ishushu nje, ubushushu belothe bungaphantsi kunomzimba wayo omnyama we-SMD.Ukongeza umoya oshushu kunokwenza ubushushu bufane ngakumbi, kwaye boyise umahluko wokufunxa ubushushu kunye nesithunzi esibi.I-infrared + ii-oveni zokubuyisela umoya oshushu zisetyenziswa kakhulu kwihlabathi.
Ekubeni imitha ye-infrared iya kuba nemiphumo emibi yomthunzi kunye ne-chromatic aberration kwiindawo ezinobude obahlukeneyo, umoya oshushu unokuvuthelwa ukulungelelanisa i-chromatic aberration kunye nokuncedisa ukusilela kweekona zayo ezifileyo.Initrogen eshushu yeyona ilungele umoya oshushu ukuba uvuthelwe.Isantya sokudluliselwa kobushushu obuguquguqukayo sixhomekeke kwisantya somoya, kodwa isantya somoya esigqithileyo siya kubangela ukufuduswa kwamacandelo kunye nokukhuthaza i-oxidation yamalungu e-solder, kwaye isantya somoya kufuneka silawulwe ku-1. Om/s~1.8III/S ifanelekile .Kukho iindlela ezimbini zokuvelisa umoya oshushu: isizukulwana se-axial fan (kulula ukwenza ukuhamba kwe-laminar, kwaye intshukumo yayo yenza ukuba umda wommandla ngamnye wobushushu ungacaci) kunye nesizukulwana se-tangential fan (i-fan ifakwe ngaphandle kwe-heater, leyo yenza imisinga yeeddy kwiphaneli ukuze indawo nganye yobushushu ikwazi ukufudunyezwa.
