Maphakathi nawo-1990s, kwakunomkhuba wokudlulisela ekushisiseni kwe-infrared + hot air ekufakweni kwe-reflow soldering e-Japan.Ishisisa ngama-30% emisebe ye-infrared kanye no-70% womoya oshisayo njengesithwali sokushisa.Ihhavini lokugeleza komoya elishisayo le-infrared lihlanganisa ngempumelelo izinzuzo zokugeleza kabusha kwe-infrared kanye nokugeleza komoya oshisayo we-convection ngempoqo, futhi iyindlela ekahle yokushisa ekhulwini lama-21.Isebenzisa ngokugcwele izici zokungena okuqinile kwemisebe ye-infrared, ukusebenza kahle kokushisa okuphezulu nokonga amandla, futhi ngesikhathi esifanayo inqoba ngempumelelo umehluko wezinga lokushisa kanye nomphumela wokuvikela we-infrared reflow soldering, futhi yenza isibambiso sokuphinda sigeleze komoya esishisayo.
Lolu hlobo lwei-reflow solderingisithando somlilo sisekelwe esithandweni se-IR futhi sengeza umoya oshisayo ukwenza izinga lokushisa esithandweni somlilo lifane kakhulu.Ukushisa okumuncwa izinto ezihlukene nemibala kuhlukile, okungukuthi, inani le-Q lihlukile, futhi umphumela wokukhuphuka kwezinga lokushisa i-AT nawo uhlukile.Isibonelo, iphakheji ye-SMD efana ne-lC i-phenolic emnyama noma i-epoxy, futhi umthofu uyinsimbi emhlophe.Uma ishisa nje, izinga lokushisa lomthofu liphansi kunomzimba walo omnyama we-SMD.Ukwengeza umoya oshisayo kungenza izinga lokushisa lifane, futhi kunqobe umehluko ekumunceni ukushisa kanye nokungafihli kahle.I-infrared + hot air reflow ovens asetshenziswe kabanzi emhlabeni.
Njengoba imisebe ye-infrared izoba nemiphumela emibi ye-shading kanye ne-chromatic aberration ezingxenyeni ezinobude obuhlukene, umoya oshisayo ungabuye uvuthelwe ukuze uhlanganise ukuphambuka kwe-chromatic futhi usize ukuntuleka kwamakhona awo afile.I-nitrogen eshisayo iyona elungele kakhulu umoya oshisayo ukuphephethwa.Isivinini sokudluliswa kokushisa okuguquguqukayo sincike esivinini somoya, kodwa isivinini somoya esibi kakhulu sizobangela ukugudluzwa kwezingxenye futhi sikhuthaze i-oxidation yamalunga e-solder, futhi isivinini somoya kufanele silawulwe ku-1. I-Om/s~1.8III/S ifanelekile .Kunezinhlobo ezimbili zokukhiqiza umoya oshisayo: i-axial fan generation (kulula ukwakha ukugeleza kwe-laminar, futhi ukunyakaza kwayo kwenza umngcele wendawo ngayinye yokushisa ungacaci) kanye nesizukulwane sabalandeli be-tangential (i-fan ifakwe ngaphandle kwe-heater, okuyinto ikhiqiza ama-eddy currents kuphaneli ukuze indawo ngayinye yokushisa ikwazi ukushisisa. control precise).
