1. Pinhole
Pinhole iterwa na adsorption ya gaze ya hydrogène hejuru yibice byashizweho, bitazasohoka igihe kirekire.Igisubizo cyo kubumba ntigishobora guhanagura hejuru yibice byashizweho, kugirango icyuma cya electrolytike gishobora kudasesengurwa.Mugihe ubunini bwikibiriti bwiyongera mukarere kegereye ihindagurika rya hydrogène, pinhole iba ikozwe kuri hydrogen ihindagurika.Kurangwa numwobo uzengurutse kandi rimwe na rimwe umurizo muto uzamutse.Iyo habuze ikibazo cyo guhanagura mugisubizo cya plaque kandi ubucucike buri hejuru ni bwinshi, pinholes ziroroshye gukora.
2. Gutera
Pockmarks ziterwa nubuso bushyizweho ntabwo busukuye, hari ibintu bikomeye byamamajwe, cyangwa ibintu bikomeye bihagarikwa mugisubizo cyisahani.Iyo zigeze hejuru yakazi kakozwe nigikorwa cyumuriro wamashanyarazi, ziba zanditseho, bigira ingaruka kuri electrolysis.Ibi bintu bikomeye byinjijwe muburyo bwa electroplating layer, utubuto duto (dumps).Ikiranga ni uko ari convex, nta kintu kibengerana, kandi nta shusho ihamye.Muri make, biterwa nigikorwa cyanduye nigisubizo cyanduye.
3. Imirongo yo mu kirere
Imyuka yo mu kirere iterwa ninyongeramusaruro zikabije cyangwa cathode nyinshi yubucucike cyangwa ibintu bigoye, bigabanya imikorere ya cathode ikora kandi bikavamo ubwinshi bwihindagurika rya hydrogen.Niba igisubizo cyo kumasahani cyatembye gahoro hanyuma cathode ikagenda gahoro, gaze ya hydrogène yagira ingaruka kumitunganyirize ya kristu ya electrolytike mugihe cyo kuzamuka hejuru yumurimo wakazi, ikora imirongo yumwuka kuva hasi kugeza hejuru.
4. Isahani ya masike (hepfo)
Isahani ya masike iterwa nuko flash yoroheje kuri pin kumwanya wa pin hejuru yumurimo wakazi itigeze ikurwaho, kandi igipande cya electrolytike ntigishobora gukorerwa hano.Ibikoresho fatizo birashobora kugaragara nyuma ya electroplating, kubwibyo byitwa hasi byerekanwe (kuberako flash yoroshye nikintu cyoroshye cyangwa kibonerana).
5. Kwambika ubusa
Nyuma ya SMD amashanyarazi no gukata no gukora, birashobora kugaragara ko habaho gucika kumurongo wa pin.Iyo habaye akavuyo hagati ya nikel na substrate, hasuzumwa ko nikel yoroheje.Iyo habaye akavuyo hagati y amabati na nikel, byemejwe ko amabati yoroheje.Byinshi mubitera ubukana ni inyongeramusaruro, urumuri rwinshi, cyangwa imyanda myinshi idasanzwe kandi kama kama mubisubizo byisahani.
