Mukuongorora kweSMT, kuongorora kwekuona uye kuongorora michina yemaziso inowanzoshandiswa.Dzimwe nzira ndedzekuongorora kuona chete, uye dzimwe inzira dzakasanganiswa.Vose vari vaviri vanogona kuongorora 100% yechigadzirwa, asi kana nzira yekuongorora yekuona yakashandiswa, vanhu vachagara vakaneta, saka hazvibviri kuona kuti vashandi vari 100% kunyatsoongorora.Naizvozvo, isu tinomisikidza yakaringana nzira yekuongorora uye yekutarisa nekumisikidza mhando yekudzora mapoinzi.
Kuti uve nechokwadi chekushanda kwakajairika kwemidziyo yeSMT, simbisa kuongororwa kwemhando yekugadzira machining workpiece mune yega yega maitiro, kuitira kuti itarise mamiriro ayo ekumhanya, uye kuseta yemhando yekudzora mapoinzi mushure memamwe maitiro akakosha.
Aya mapoinzi ekudzora anowanzo kuwanikwa munzvimbo dzinotevera:
1. PCB kuongororwa
(1) Hapana deformation yebhodhi rakadhindwa;
(2) Kana iyo welding pad yakasvibiswa;
(3) Hapana mavanga pamusoro pebhodhi rakadhindwa;
Nzira yekuongorora: Kuongorora kwekuona zvinoenderana nechiyero chekuongorora.
2. Screen printing yekuona
(1) Kana kudhinda kwapera;
(2) Kana kuine zambuko;
(3) Kana ukobvu hwakafanana;
(4) Hapana mupendero kuputsika;
(5) Hapana kutsauka pakudhinda;
Nzira yekuongorora: kuongorora kwekuona kana kukudza girazi rekuongorora zvichienderana nechiyero chekuongorora.
3. Patch test
(1) Nzvimbo yekukwira yezvikamu;
(2) Kana paine donhwe;
(3) Hapana mativi asina kururama;
Nzira yekuongorora: kuongorora kwekuona kana kukudza girazi rekuongorora zvichienderana nechiyero chekuongorora.
4. Reflow ovhenikuonekwa
(1) Welding mamiriro ezvinhu, ingave paine bhiriji, stele, dislocation, solder bhora, virtual welding uye zvimwe zvakaipa welding phenomena.
(2) Mamiriro ezvinhu ejoint solder.
Nzira yekuongorora: kuongorora kwekuona kana kukudza girazi rekuongorora zvichienderana nechiyero chekuongorora.
