Ubwino wa SMTreflow uvunindondomeko n'chakuti kutentha ndi kosavuta kulamulira, makutidwe ndi okosijeni akhoza kupewedwa pa ndondomeko soldering, ndi mtengo wa zinthu zopangira ndi zosavuta kulamulira.Pali gulu la magetsi otenthetsera magetsi mkati mwa chipangizochi, chomwe chimatenthetsa nayitrogeni mpaka kutentha kokwanira ndikuchiwombera ku bolodi la dera kumene zigawozo zayikidwa, kotero kuti solder kumbali zonse ziwiri za zigawozo zimasungunuka ndikumangirira ndi chachikulu. bolodi.TYtechagawana njira zina zokometsera za SMT reflow soldering process pano.
1. M'pofunika kukhazikitsa sayansi ya SMT reflow soldering curve ndikuyesa kuyesa nthawi yeniyeni ya kutentha kwapakati pafupipafupi.
2. Solder malinga ndi reflow soldering malangizo pa PCB mapangidwe.
3. Panthawi ya SMT reflow soldering process, lamba wotumizira ayenera kutetezedwa kuti zisagwedezeke.
4. Mphamvu ya reflow soldering ya bolodi yoyamba yosindikizidwa iyenera kufufuzidwa.
5. Kaya SMT reflow soldering ndi yokwanira, kaya pamwamba pa mgwirizano wa solder ndi wosalala, kaya mawonekedwe a solder ndi theka la mwezi, chikhalidwe cha solder mipira ndi zotsalira, chikhalidwe cha soldering mosalekeza ndi pafupifupi soldering.Onaninso zinthu monga kusintha mtundu pa PCB pamwamba.Ndipo sinthani kutentha kwa kutentha malinga ndi zotsatira zoyendera.Panthawi yonse yopanga batch, mtundu wa kuwotcherera uyenera kuyang'aniridwa pafupipafupi.
6. Nthawi zonse sungani kutsekemera kwa SMT reflow soldering.Chifukwa chakugwira ntchito kwa nthawi yayitali kwa makinawo, zowononga organic kapena zosakhala ngati rosin zolimba zimalumikizidwa.Pofuna kupewa kuipitsidwa kwachiwiri kwa PCB ndikuwonetsetsa kuti ndondomekoyi ikuyendetsedwa bwino, kukonza ndi kuyeretsa nthawi zonse kumafunika.
