Kubatsira kweSMTreflow ovenmaitiro ndeokuti tembiricha iri nyore kudzora, oxidation inogona kudziviswa panguva yekushambadzira, uye mutengo wezvigadzirwa zvekugadzira zvakare nyore kudzora.Pane seti yemagetsi ekudziya maseketi mukati memudziyo uyu, iyo inopisa nitrogen kusvika pakakwirira zvakakwana tembiricha uye inoivhuvhuta kubhodhi redunhu uko zvikamu zvakanamirwa, kuitira kuti solder pamativi ese ezvikamu zvinyunguduke uye zvisungo neiyo huru. board.TYtechichagovera imwe yenzira yekugonesa yeSMT reflow soldering process pano.
1. Izvo zvinodikanwa kumisikidza yesainzi SMT reflow soldering tembiricha curve uye kuita chaiyo-nguva yekuyedza yetembiricha curve nguva nenguva.
2. Solder maererano ne reflow soldering direction panguva yePCB design.
3. Munguva yeSMT reflow soldering process, bhandi rekutakura rinofanira kudzivirirwa kubva pakudedera.
4. The reflow soldering effect yebhodhi rakadhindwa rekutanga rinofanira kuongororwa.
5. Kana iyo SMT reflow soldering yakakwana, kana nzvimbo yejojo ye solder iri nyore, kana chimiro chejojo ye solder ihafu-mwedzi, mamiriro ekutengesa mabhora uye zvakasara, mamiriro ekuenderera mberi kwekutengesa uye virtual soldering.Tarisa zvakare kune zvinhu zvakaita sekuchinja kwemavara paPCB pamusoro.Uye gadzirisa tembiricha curve zvinoenderana nemhedzisiro yekuongorora.Munguva yese yekugadzira batch maitiro, iyo welding mhando inofanirwa kuongororwa nguva nenguva.
6. Nguva dzose chengetedza SMT reflow soldering.Nekuda kwekushanda kwenguva refu kwemuchina, organic kana inorganic zvinosvibisa senge solidified rosin zvakabatanidzwa.Kuti udzivise kusvibiswa kwechipiri kwePCB uye kuve nechokwadi chekushandiswa kwakanaka kwemaitiro, kugadzirisa nguva dzose uye kuchenesa kunodiwa.
