1. Filhu

Ƙunƙarar ƙugiya ta samo asali ne saboda adsorption na iskar hydrogen a saman sassan da aka yi, wanda ba za a saki ba na dogon lokaci. Maganin plating ba zai iya jika saman ɓangarorin da aka yi da su ba, ta yadda ba za a iya tantance Layer plating na electrolytic ta hanyar lantarki ba. Yayin da kaurin rufin ya karu a yankin da ke kusa da ma'aunin juyin halittar hydrogen, an kafa pinhole a wurin juyin halittar hydrogen. Halaye da rami zagaye mai sheki da wani lokacin ƙaramin wutsiya mai juyi. Lokacin da rashin jikewa wakili a cikin plating bayani da kuma yawan halin yanzu yana da girma, pinholes suna da sauƙin samuwa.

2. Fitowa

Alamun alatu saboda saman da aka yi masa ba shi da tsabta, akwai abubuwa masu ƙarfi da aka tallata, ko kuma an dakatar da abubuwa masu ƙarfi a cikin maganin plating. Lokacin da suka isa saman kayan aiki a ƙarƙashin aikin filin lantarki, ana tallata su akan shi, wanda ke shafar electrolysis. Wadannan daskararrun abubuwa suna kunshe a cikin A cikin Layering electroplating, an kafa ƙananan ƙullun (juji). Halin shi ne cewa yana da kullun, babu wani abu mai haske, kuma babu tsayayyen siffar. A takaice, yana faruwa ta hanyar datti workpiece da datti plating bayani.

3. Ragewar iska

Rage kwararar iska saboda abubuwan da suka wuce kima ko babban adadin cathode na yanzu ko wakili mai rikitarwa, wanda ke rage tasirin cathode na yanzu kuma yana haifar da babban adadin juyin halittar hydrogen. Idan bayani na plating yana gudana a hankali kuma cathode ya motsa a hankali, iskar hydrogen zai shafi tsari na lu'ulu'u na electrolytic yayin aiwatar da tashi sama da saman kayan aikin, samar da ratsi na iska daga ƙasa zuwa sama.

4. Mask plating (wanda aka fallasa ƙasa)

Mask plating saboda gaskiyar cewa filashi mai laushi a wurin fil akan saman kayan aikin ba a cire shi ba, kuma ba za a iya yin abin rufe murfin lantarki a nan ba. Ana iya ganin kayan tushe bayan electroplating, don haka ana kiransa fallasa ƙasa (saboda filasha mai laushi shine ɓangaren resin translucent ko m).

5. Rufe hanci

Bayan SMD electroplating da yankan da kafa, ana iya ganin cewa akwai fashe a lankwasa fil. Lokacin da akwai tsagewa tsakanin nickel Layer da substrate, ana yin hukunci cewa Layer nickel ya karye. Lokacin da aka sami tsaga tsakanin Layer tin da nickel Layer, ana ƙaddara cewa Layer ɗin ya lalace. Yawancin abubuwan da ke haifar da ɓarna sune abubuwan da ake ƙarawa, masu haske da yawa, ko ƙazanta marasa ƙarfi da na halitta da yawa a cikin maganin plating.
