1. Khomo
Pinhole imabwera chifukwa cha kutsekemera kwa mpweya wa haidrojeni pamwamba pa zigawo zopukutidwa, zomwe sizidzatulutsidwa kwa nthawi yayitali. Yankho plating sangathe kunyowetsa pamwamba pa plating zigawo, kotero kuti electrolytic plating wosanjikiza sangathe electrolytically kusanthula. Pamene makulidwe a zokutira akuwonjezeka m'dera lozungulira hydrogen evolution point, pinhole imapangidwa pa hydrogen evolution point. Amadziwika ndi dzenje lozungulira lonyezimira ndipo nthawi zina mchira wawung'ono wopindika. Pakakhala kusowa kwa chonyowetsa mu plating yankho ndipo kachulukidwe kakali pano ndi wokwera, ma pinholes ndi osavuta kupanga.
2. Kuboola
Pockmarks ndi chifukwa chakuti pamwamba yokutidwa si oyera, pali zinthu zolimba adsorbed, kapena zinthu zolimba imayimitsidwa mu plating njira. Akafika pamwamba pa workpiece pansi pa ntchito ya magetsi, iwo amalowetsedwa pa izo, zomwe zimakhudza electrolysis. Zinthu zolimbazi zimayikidwa mu gawo la Electroplating, tokhala ting'onoting'ono (zotayira) zimapangidwa. Chikhalidwe chake ndi chakuti ndi convex, palibe chowoneka chowala, ndipo palibe mawonekedwe okhazikika. Mwachidule, zimayamba chifukwa cha zonyansa zogwirira ntchito komanso njira yakuda ya plating.
3. Mikwingwirima ya mpweya
Kuthamanga kwa mpweya kumachitika chifukwa cha zowonjezera zowonjezera kapena kachulukidwe kakakulu kameneka kameneka kamene kamakhala kachulukidwe kamene kalikonse kamene kalikonse kamene kamapangitsa kuti ma cathode ayambe kugwira ntchito ndipo kumapangitsa kuti ma hydrogen azisintha kwambiri. Ngati plating njira unayenda pang'onopang'ono ndi cathode anasuntha pang'onopang'ono, mpweya wa haidrojeni zingakhudze dongosolo la makhiristo electrolytic pa ndondomeko kukwera pamwamba pa workpiece, kupanga airflow mikwingwirima kuchokera pansi mpaka pamwamba.
4. Kupaka chigoba (chowonekera pansi)
Kupaka chigoba ndi chifukwa chakuti kung'anima kofewa pa malo a pini pamwamba pa workpiece sikunachotsedwe, ndipo kuyanika kwa electrolytic sikungathe kuchitidwa pano. Zomwe zili m'munsi zimatha kuwonedwa pambuyo pa electroplating, kotero zimatchedwa pansi poyera (chifukwa kung'anima kofewa ndi gawo lowonekera kapena lowonekera).
5. Kuphimba brittleness
Pambuyo pa SMD electroplating ndi kudula ndi kupanga, zikhoza kuwoneka kuti pali ming'alu pa kupindika kwa pini. Pakakhala mng'alu pakati pa nickel wosanjikiza ndi gawo lapansi, amaweruzidwa kuti nickel wosanjikiza ndi brittle. Pakakhala mng'alu pakati pa malata ndi nickel wosanjikiza, zimatsimikiziridwa kuti tani wosanjikiza ndi brittle. Zambiri zomwe zimayambitsa kuwonongeka ndi zowonjezera, zowunikira mopitilira muyeso, kapena zinyalala zambiri za inorganic ndi organic mu plating solution.
