Kungani kunjaloi-reflow solderingebizwa ngokuthi "reflow"?Ukugeleza kabusha kwe-reflow soldering kusho ukuthi ngemuva kwe-unamathisele solderifinyelela endaweni yokuncibilika ye-solder paste, ngaphansi kwesenzo sokungezwani kwendawo ye-liquid tin kanye ne-flux, ithini eliwuketshezi ligeleza kabusha kumaphini wengxenye ukwenza amajoyinti e-solder, okuvumela inqubo yesekethe A lapho amaphedi ebhodi kanye nezingxenye kufakwe khona. okudayiselwe konke kubizwa nangokuthi inqubo "yokugeleza kabusha".
1. Uma ibhodi le-PCB lingena endaweni yokufudumeza kabusha, isincibilikisi negesi ekunamathisele we-solder kuyahwamuka.Ngesikhathi esifanayo, i-flux in the solder paste imanzisa ama-pads, izingxenye zokuphela kanye nezikhonkwane, futhi i-solder paste iyathambisa futhi igoqe., Ukumboza iphedi, ukuhlukanisa i-pad kanye nezikhonkwane zengxenye ku-oxygen.
2. Lapho ibhodi lesekethe le-PCB lingena endaweni yokufakwa kabusha kwe-reflow soldering, i-PCB kanye nezingxenye zishiswa ngokugcwele ukuvimbela i-PCB ukuthi ingangeni ngokuzumayo endaweni yokushisa ephezulu yokushisela nokulimaza i-PCB nezingxenye.
3. Uma i-PCB ingena endaweni yokudayiswa kabusha, izinga lokushisa likhuphuka ngokushesha ukuze i-solder paste ifinyelele esimweni esincibilikisiwe, futhi i-solder ewuketshezi imanzisa futhi ihlukanise amaphedi, iziphetho zengxenye kanye nezikhonkwane ze-PCB, futhi ithini eliwuketshezi ligeleza futhi lixube. ukwakha amalunga e-solder.
4. I-PCB ingena endaweni yokupholisa yokugeleza kabusha, bese ithini eliwuketshezi ligeleza kabusha ukuze liqinise amalunga e-solder ngomoya obandayo we-reflow soldering;ngalesi sikhathi, i-reflow soldering iphelile.
Yonke inqubo yokusebenza ye-reflow soldering ayinakuhlukaniswa nomoya oshisayo esithandweni sokugeleza kabusha.I-Reflow soldering incike esenzweni sokugeleza komoya oshisayo kumajoyinti e-solder.I-flux efana ne-jelly ibhekana nokusabela ngokomzimba ngaphansi kokugeleza komoya okushisa okuphezulu ukuze kuzuzwe i-SMD soldering;i-reflow soldering ” “Reflow” kungenxa yokuthi igesi izungeza emuva naphambili emshinini wokushisela ukuze ikhiqize izinga lokushisa eliphezulu ukuze kufezwe injongo yokushisela, ngakho kubizwa ngokuthi i-reflow soldering.
