Reflow ovheniinoshandiswa solder redunhu bhodhi chigamba zvikamu mukatiSMT mutsara wekugadzira.Zvakanakira reflow soldering muchina ndezvekuti tembiricha inodzorwa zviri nyore, oxidation inodzivirirwa panguva yewelding process, uye mutengo wekugadzira unodzorwa zviri nyore.Kune dunhu rekudziya mukati mehovhoni reflow, uye iyo nitrogen inopisa kusvika kune yakakwira tembiricha uye yobva yapeperetswa kune redunhu bhodhi iro rakanamirwa kune zvikamu, kuitira kuti solder pamativi ese ezvikamu zvinyunguduke uye kusungirirwa. motherboard.Chii chimiro che reflow furnace?Ndapota ona zvinotevera:
Iyo reflow oven inonyanya kuumbwa nemhepo inoyerera system, yekudziya system, kutonhora system, transmission system, flux recovery system, exhaust gasi kurapwa uye kudzoreredza mudziyo, cap air pressure yekusimudza mudziyo, exhaust mudziyo uye zvimwe zvimiro uye chimiro maumbirwo.

I. Air flow system ye reflow oven
Basa remhepo inoyerera system ndeyepamusoro convection kunyatsoita, kusanganisira kumhanya, kuyerera, fluidity uye permeability.

II.Reflow oven heat system
Iyo yekudziya system inoumbwa neinopisa mhepo mota, yekudziya chubhu, thermocouple, solid state relay, tembiricha yekudzora mudziyo uye zvichingodaro.

III.Kutonhodza system yereflow oven
Basa reiyo yekutonhodza system ndere kutonhodza iyo inopisa PCB nekukurumidza.Kazhinji pane nzira mbiri: kutonhora kwemhepo uye kutonhora kwemvura.

IV.Reflow soldering muchina dhiraivha system
Transmission system inosanganisira mesh bhandi, njanji yekutungamira, tsigiro yepakati, cheni, mota yekufambisa, track hupamhi gadziriso chimiro, yekufambisa kumhanya yekudzora michina uye zvimwe zvikamu.

V. Flux recovery system ye reflow oven
Flux exhaust gasi kudzoreredza system inowanzo shongedzerwa ne evaporator, kuburikidza ne evaporator ichapisa gasi rekuburitsa kusvika kupfuura 450 ℃, iyo flux volatiles gasification, uyezve muchina wekutonhora wemvura mushure mekutenderera kuburikidza ne evaporator, inoyerera kuburikidza neyepamusoro fan yekubvisa, kuburikidza ne evaporator inotonhorera mvura inoyerera ichienda kune yekudzosera tangi.

VI.Waste gasi kurapwa uye kudzoreredza mudziyo we reflow oveni
Chinangwa chemarara gasi kurapwa uye kudzoreredza mudziyo unonyanya kuve nemapoinzi matatu: kuchengetedzwa kwezvakatipoteredza zvinodiwa, usarega iyo flux inoputika yakananga mumhepo;Iko kuomeswa uye kunaya kwemarara gasi muchoto chekuyerera kuchakanganisa kuyerera kwemhepo inopisa uye kuderedza kushanda kweconvection, saka inoda kudzokororwa.Kana nitrogen reflow furnace yakasarudzwa, kuitira kuchengetedza nitrogen, zvakakosha kudzokorora nitrogen.Flux exhaust gasi kudzoreredza system inofanirwa kuve nemidziyo.

VII.Mhepo inomanikidza yekusimudza mudziyo we reflow soldering muchina wepamusoro chivharo
Chivharo chepamusoro che reflow soldering oven inogona kuvhurwa yese kuti ifambise kucheneswa kwe reflow soldering vira.Kana ndiro inodonha panguva yekugadzirisa kana kugadzirwa kwevira reflow soldering, chivharo chepamusoro che reflow soldering furnace inofanira kuvhurwa.

VIII.Reflow soldering muchina chimiro chimiro
Chimiro chekunze chakashongedzwa nesimbi yepepa.
