Sei zvakadaroreflow solderinginonzi "reflow"?The reflow reflow soldering zvinoreva kuti mushure mesolder pasteinosvika pakunyunguduka kwesolder paste, pasi pekuita kwekukakavadzana kwemvura yetini uye kuyerera, iyo tini yemvura inoyerera ichienda kune chikamu chepini kuti igadzire majoini ekutengesa, ichibvumira dunhu A maitiro umo bhodhi pads uye zvikamu zviri. inotengeswa mune yese inonziwo "reflow" process.
1. Kana iyo PCB board ichipinda munzvimbo yekudziya yekuyerera, iyo solvent uye gasi mune solder paste inoputika.Panguva imwecheteyo, iyo inoyerera mune solder paste inonyorovesa mapedhi, chikamu chinopera uye mapini, uye solder paste inopfava uye inodonha., Kuvhara padhi, kuparadzanisa padhi uye chikamu mapini kubva kuokisijeni.
2. Kana iyo PCB yedunhu bhodhi ichipinda mu reflow soldering insulation nharaunda, iyo PCB uye zvikamu zvinopisa zvizere kudzivirira PCB kuti isangoerekana yapinda munzvimbo yepamusoro yekupisa yewelding uye kukuvadza PCB uye zvikamu.
3. Kana PCB ichipinda mu reflow soldering area, tembiricha inokwira nekukurumidza zvekuti solder paste inosvika pakunyungudutswa, uye liquid solder inonyorova nekuparadzira mapedhi, chikamu chinogumira uye mapini ePCB, uye tini remvura rinoyerera nekusanganiswa. kugadzira majoini ekutengesa.
4. PCB inopinda munzvimbo inotonhorera ye reflow, uye tini yemvura inoyerera zvakare kuti isimbise majoini ekutengesa nemhepo inotonhora ye reflow soldering;panguva ino, reflow soldering inopedzwa.
Basa rose rekushanda reflow soldering harina kuparadzaniswa kubva kumhepo inopisa muvira reflow.Reflow soldering inovimba nekuita kwekuyerera kwemhepo inopisa pamajoini ekutengesa.Iyo jelly-senge flux inosangana nekuita kwemuviri pasi peimwe tembiricha yepamusoro yekuyerera kwemhepo kuti uwane SMD solder;reflow soldering ” “Reflow” imhaka yekuti gasi rinotenderera richidzokera kumashure mumuchina wewelding kuti ugadzire tembiricha yakakwira kuti izadzise chinangwa chewelding, saka inodaidzwa kunzi reflow soldering.
