Nthawi zogwirira ntchito: Akuti pafupifupi 25% -30% ya ma PCB omwe amagwiritsa ntchito njira ya OSP pakadali pano, ndipo kuchuluka kwachulukira (ndikutheka kuti njira ya OSP tsopano yaposa malata opopera ndikuyika koyamba).Njira ya OSP ingagwiritsidwe ntchito pa ma PCB otsika kwambiri kapena ma PCB apamwamba kwambiri, monga ma PCB a TV a mbali imodzi ndi ma board olongedza chip apamwamba kwambiri.Kwa BGA, palinso ambiriOSPmapulogalamu.Ngati PCB ilibe zofunikira zolumikizirana pamtunda kapena zoletsa nthawi yosungira, njira ya OSP ikhala njira yabwino kwambiri yochizira pamwamba.

Ubwino waukulu: Lili ndi ubwino wonse wa kuwotcherera bolodi wopanda mkuwa, ndipo bolodi lomwe latha (miyezi itatu) likhoza kubwezeretsedwanso, koma kawirikawiri kamodzi kokha.

Zoipa: kutengeka ndi asidi ndi chinyezi.Ikagwiritsidwa ntchito pakusokera kwachiwiri, iyenera kumalizidwa mkati mwa nthawi inayake.Nthawi zambiri, zotsatira za soldering yachiwiri reflow adzakhala osauka.Ngati nthawi yosungiramo idutsa miyezi itatu, iyenera kubwerezedwanso.Gwiritsani ntchito mkati mwa maola 24 mutatsegula phukusi.OSP ndi wosanjikiza insulating, choncho mayeso mfundo ayenera kusindikizidwa ndi solder phala kuchotsa original OSP wosanjikiza kukhudzana pini mfundo kuyezetsa magetsi.

Njira: Pamalo oyera opanda mkuwa, filimu yachilengedwe imakulitsidwa ndi njira yamankhwala.Kanemayu ali ndi anti-oxidation, kutenthedwa kwa kutentha, kukana chinyezi, ndipo amagwiritsidwa ntchito kuteteza pamwamba pa mkuwa kuti asachite dzimbiri (oxidation kapena vulcanization, etc.) m'malo abwino;panthawi imodzimodziyo, iyenera kuthandizidwa mosavuta mu kutentha kwakukulu kwa kutentha kwa kuwotcherera.Flux imachotsedwa mwamsanga kwa soldering;
