Munguva yemazuva ano yekukura kuri kuwedzera kwezvigadzirwa zvemagetsi, kuitira kuti utsvage hudiki hudiki hunogona kukura uye kusangana kwakasimba kweplug-ins, maPCB ane mativi maviri ave akakurumbira, uye nekuwedzera, vagadziri kuti vagadzire zvidiki, zvakanyanya. compact uye yakaderera-mutengo zvigadzirwa.Mune inotungamira-isina reflow soldering process, kaviri-sided reflow soldering yakashandiswa zvishoma nezvishoma.
Kaviri-mativi kutungamirira-isina reflow soldering process yekuongorora:
Muchokwadi, mazhinji aripo akapetwa-mativi ePCB mabhodhi achiri kutengesa chikamu chechikamu nekuyerera, uyezve tengesa iyo yepini parutivi neave soldering.Mamiriro ezvinhu akadaro ndeazvino maviri-sided reflow soldering, uye pachine mamwe matambudziko mukuita ayo asina kugadziriswa.Chikamu chepasi chebhodhi hombe chiri nyore kudonha panguva yechipiri reflow process, kana chikamu chepasi solder chibatanidzwa chinonyunguduka kukonzera matambudziko ekuvimbika kwejoini rekutengesa.
Saka, isu tinofanira sei kuwana mbiri-mativi reflow soldering?Yekutanga ndeye kushandisa glue kunamira zvikamu pairi.Painoshandurwa uye ichipinda mune yechipiri reflow soldering, zvikamu zvichagadziriswa pairi uye hazvizodonha.Iyi nzira iri nyore uye inoshanda, asi inoda mimwe michina uye mashandiro.Matanho ekupedzisa, zvinowanzowedzera mutengo.Chechipiri ndechekushandisa ma solder alloys ane mapoinzi akasiyana ekunyungudika.Shandisa yakakwira melting point alloy kudivi rekutanga uye yakaderera melting point alloy kune yechipiri divi.Dambudziko neiyi nzira nderekuti kusarudzwa kweiyo yakaderera melting point alloy inogona kukanganiswa nechigadzirwa chekupedzisira.Nekuda kwekudzikisira tembiricha yekushanda, maalloys ane yakakwira kunyungudika anozowedzera tembiricha yereflow soldering, izvo zvinokonzeresa kukuvadza kune zvikamu uye PCB pachayo.
Pamusoro pezvikamu zvakawanda, kudzvinyirirwa kwepamusoro kwetini yakanyungudutswa pajoini yakakwana kuti ibate chikamu chepasi uye kuumba chikwata chepamusoro chekutengesa.Muyero we30g/in2 unowanzoshandiswa mukugadzira.Nzira yechitatu ndeyekuvhuvhuta mhepo inotonhora pazasi pechoto, kuitira kuti tembiricha ye solder point pazasi pePCB inogona kuchengetwa pazasi pekunyungudika kwechipiri reflow soldering.Pamusana pekusiyana kwekushisa pakati pepamusoro nepamusoro pepamusoro, kushushikana kwemukati kunogadzirwa, uye nzira dzinoshanda uye nzira dzinodiwa kuti dzibvise kushushikana nekuvandudza kuvimbika.
