Nheyo yePCBA reflow solderinginzira inowanzoshandiswa pamusoro pekumisikidza tekinoroji yekugadzira zvinhu zvemagetsi kune akadhindwa edunhu mabhodhi (PCBs).
The reflow soldering musimboti wakavakirwa pamisimboti yekupisa conduction uye kunyunguduka kwezvinhu solder.Chekutanga, solder paste inoshandiswa kune inodiwa solder nzvimbo paPCB.Solder paste ine metallic alloy, inowanzo umbwa nemutobvu, tini, uye mamwe masimbi anonyungudika.
Zvadaro, pamusoro pegomo components (SMD) zvakanyatsoiswa pane solder paste.Next, PCB uye zvikamu zviri pamwe chete zvakapfuudzwa muhovhoni reflow, apo tembiricha yekushisa inodzorwa.Reflow soldering inoda kupisa uye kutonhora maitiro muzvikamu zviviri zvikuru.Kupisa danho: Tembiricha inokwira zvishoma nezvishoma, zvichiita kuti solder paste itange kunyunguduka.Iyo metallic alloy mune solder paste inonyunguduka uye inoita mamiriro emvura.
Munguva iyi, tembiricha inofanirwa kusvika padanho rakakwana kuti ive nechokwadi chekuti majoini e solder anyungudutswa, asi kwete zvakanyanya kukuvadza zvimwe zvikamu muovheni reflow kana PCB.Soldering nhanho: Nepo iyo solder paste iri kunyunguduka, iyo solder majoini anogadzira magetsi. uye ma mechanical connections pakati pePCB uye zvikamu.Kana majoini emasoja asvika patembiricha yakafanira, zvidimbu zvebhora resimbi mune solder paste zvinotanga kuita mabhora erata.Chinhanho chekutonhodza: Tembiricha iri muhovhoni yereflow inotanga kuderera, zvichiita kuti solder paste ikurumidze kutonhora uye kuoma, kuita majoini anotengeswa akagadzikana.
Mushure mekunge majoini e solder atonhora, solder paste inosimbisa uye inobatanidza zvakasimba PCB uye zvikamu pamwe chete.Kiyi ye reflow soldering ndeye kudzora tembiricha yekushisa muhovheni yekutsvaira kuti ive nechokwadi chekunyunguduka kwesolder paste, uye kuti majoini anotengeswa asvike. gadzira hukama hwakavimbika uye hwakasimba nePCB uye zvikamu.
Pamusoro pezvo, kunaka kweiyo solder paste kunokanganisawo kunaka kweiyo solder, saka kusarudza yakakodzera solder paste kuumbwa kwakakosha.Muchidimbu, musimboti wePCBA reflow sol.
