Ngatiite ongororo yeDFM/DFA kwauri tobva tadzoka kwauri nemushumo. Unogona kurodha mafaira ako zvakachengeteka kuburikidza newebhusaiti yedu. Tinoda ruzivo runotevera kuti tikupe mutengo:
-
- Gerber, ODB++, kana .pcb, spec.
- BOM rondedzero kana iwe uchida kusangana
- uwandu
- Kuchinja nguva
Kune masevhisi ePCBA, ndapota ipa BOM yako (Bhiri reZvinhu) uye chero mirairo yegungano. Isu tinopawo DFM/DFA ongororo yekukwidziridza zvigadziriso zvako zvekugadzira uye kusangana, kuve nechokwadi chekuita kwakatsetseka kwekugadzira.
