1. Kutentha kwa mpweya wotentha kumagwiritsidwa ntchito pamwamba pa PCB yosungunula malata otsogolera ndi kutenthetsa mpweya woponderezedwa (kuwomba lathyathyathya). Kuchipanga kukhala chotchinga chosamva ma oxidation kungapereke kutsekemera kwabwino. Mpweya wotentha wa solder ndi mkuwa umapanga chigawo chamkuwa-sikkim pamphambano, ndi makulidwe pafupifupi 1 mpaka 2mil.
2. Organic Solderability Preservative (OSP) pokulitsa zokutira za organic pa mkuwa wopanda kanthu. Izi PCB multilayer filimu amatha kukana makutidwe ndi okosijeni, kutentha kutentha, ndi chinyezi kuteteza mkuwa pamwamba pa dzimbiri (makutidwe ndi okosijeni kapena sulfure, etc.) pansi pa zinthu zabwinobwino. Pa nthawi yomweyo, pa kutentha wotsatira kuwotcherera, kuwotcherera flux mosavuta kuchotsedwa mwamsanga.

3. Ni-au mankhwala TACHIMATA mkuwa pamwamba ndi wandiweyani, zabwino ni-au aloyi magetsi katundu kuteteza PCB multilayer bolodi. Kwa nthawi yayitali, mosiyana ndi OSP, yomwe imagwiritsidwa ntchito ngati wosanjikiza wa dzimbiri, imatha kugwiritsidwa ntchito nthawi yayitali ya PCB ndikupeza mphamvu zabwino. Kuphatikiza apo, ili ndi kulekerera kwachilengedwe komwe njira zina zochizira pamwamba sizikhala nazo.

4. Electroless siliva mafunsidwe pakati OSP ndi electroless faifi tambala / golide plating, PCB multilayer ndondomeko ndi yosavuta komanso mofulumira.

Kuwonekera kumadera otentha, achinyezi ndi oipitsidwa kumaperekabe magetsi abwino komanso kutenthetsa bwino, koma kodetsa. Chifukwa palibe faifi tambala pansi pa wosanjikiza siliva, siliva wayamba alibe mphamvu zonse zabwino thupi plating faifi tambala plating / golide kumizidwa.

5.Woyendetsa pamwamba pa PCB multilayer board amakutidwa ndi golide wa nickel, poyamba ndi wosanjikiza wa nickel ndiyeno ndi golide. Cholinga chachikulu cha nickel plating ndikuletsa kufalikira pakati pa golide ndi mkuwa. Pali mitundu iwiri ya golide wonyezimira wa nickel: golide wofewa (golide woyera, kutanthauza kuti samawoneka wowala) ndi golidi wolimba (wosalala, wolimba, wosavala, cobalt ndi zinthu zina zomwe zimawoneka zowala). Golide wofewa amagwiritsidwa ntchito makamaka pakuyika golide mzere wagolide; Golide wolimba amagwiritsidwa ntchito makamaka polumikizana ndi magetsi osawotcherera.

6. Ukadaulo waukadaulo wa PCB wosakanikirana sankhani njira ziwiri kapena zingapo zochizira pamwamba, njira zodziwika bwino ndi izi: faifi tambala golide anti-oxidation, faifi tambala plating golide mpweya faifi tambala golide, faifi tambala plating golide otentha mpweya kusanja, faifi tambala wolemera ndi golidi kutentha mpweya kusanja. Ngakhale kuti kusintha kwa PCB multilayer pamwamba pa chithandizo sikuli kofunikira ndipo kumawoneka kutali, ziyenera kuzindikiridwa kuti nthawi yayitali yosintha pang'onopang'ono idzabweretsa kusintha kwakukulu. Ndi kuchuluka kwa kufunikira kwa chitetezo cha chilengedwe, ukadaulo waukadaulo wa PCB uyenera kusintha kwambiri mtsogolo.
