Kapangidwe ka PCB ikamalizidwa, tiyenera kuyang'ana zonse zomwe polojekitiyi ikuchita.Monga momwe tingamalizire pepala loyesa tokha, tiyenera kuchita kafukufuku wosavuta ndikuwunikanso mavuto ake onse, kuti tiwonetsetse kuti sitidzalakwitsa kwambiri chifukwa cha kunyalanyaza.Otsatirawa opanga neoden mounter kufotokoza mmene troubleshoot PCBA processing yochepa dera zolakwika zokhudzana chidziwitso.
1. Tsegulani mapangidwe a PCB pa kompyuta, maukonde afupipafupi akuyatsa, onani malo omwe ali pafupi kwambiri, omwe angagwirizane kwambiri ndi chidutswa.Samalani kwambiri ndi IC internal short circuit.Ngati manual soldering, kukhala ndi makhalidwe abwino:.
2. Musanagulitsidwe kuti muyang'ane pamanja pa bolodi la PCB kamodzi, ndikugwiritsa ntchito multimeter kuti muwone mabwalo ofunika (makamaka magetsi ndi nthaka) kaya ndi yochepa.
3. Nthawi iliyonse mutatha kuwotcherera chip kuti mugwiritse ntchito multimeter kuyeza mphamvu yamagetsi ndikuyika ngati pali dera lalifupi.
4. PCBA kupanga soldering nthawi musati kuponya chitsulo, mwangozi akuponya solder ku mapazi chip soldering (makamaka tebulo zomata zigawo), n'zosavuta kupeza chodabwitsa yochepa dera.Tengani bolodi kuti mudule mzere (makamaka oyenera pa bolodi limodzi/lawiri wosanjikiza), dulani mzerewo pambuyo poti mbali iliyonse ya midadada yogwira ntchito idalimbikitsidwa, ndikuchotsedwa pang'onopang'ono.
5. Kugwiritsa ntchito zida zowunikira malo ocheperako.
6. PCBA Chip processing BGA Chip, chifukwa olowa onse solder yokutidwa ndi Chip wosaoneka, ndi Mipikisano wosanjikiza bolodi (oposa 4 zigawo), ndiye ndi bwino anagawa mphamvu mu kapangidwe ka chip aliyense, ndi mkanda wa maginito kapena 0 ohm kugwirizana kwa dzuwa kwa dzuwa, kotero kuti pali magetsi okhala ndi kachigawo kakang'ono mpaka pansi, kusokoneza kuzindikira kwa maginito a mkanda, ndikosavuta kudziwa m'badwo wa chip.Chifukwa cha vuto la BGA soldering, kuwotcherera Buku, ngati osasamala adzakhala moyandikana ndi magetsi ndi pansi mipira iwiri solder yochepa-circuited.
7. Small-kakulidwe tebulo chomata capacitor kuwotcherera ayenera kusamala, makamaka magetsi fyuluta capacitor (103 kapena 104), chiwerengero chachikulu, n'zosavuta chifukwa magetsi ndi nthaka yochepa.
