1. Pinhole

Ngwunye pinhole bụ n'ihi mgbasa ozi nke hydrogen gas n'elu akụkụ nke plated, nke na-agaghị ahapụ ya ogologo oge. Ihe ngwọta nke plating enweghị ike ime ka mmiri dị n'elu akụkụ ndị a kpuchiri ekpuchi, nke mere na a pụghị inyocha oyi akwa electrolytic nke electrolytically. Ka ọkpụrụkpụ nke mkpuchi na-abawanye na mpaghara gburugburu ebe evolushọn hydrogen, a na-emepụta pinhole na ebe evolushọn hydrogen. Ejiri oghere okirikiri na-egbu maramara na mgbe ụfọdụ obere ọdụ elu elu. Mgbe enweghi onye na-ahụ maka wetting na ngwọta plating na njupụta dị ugbu a dị elu, pinholes dị mfe ịmepụta.

2. Ịkpọtu

Pockmarks bụ n'ihi na elu ịbụ plated adịghị ọcha, e nwere siri ike bekee adsorbed, ma ọ bụ siri ike bekee kwụsịtụrụ na plating ngwọta. Mgbe ha rutere n'elu nke workpiece n'okpuru ọrụ nke eletrik eletrik, ha na-adsorbed na ya, nke na-emetụta electrolysis. A na-etinye ihe ndị a siri ike n'ime oyi akwa electroplating, a na-emepụta obere bumps (mkpọpu). Ihe e ji mara ya bụ na ọ bụ convex, ọ dịghị ihe na-egbuke egbuke, ọ dịghịkwa ọdịdị edozi. Na nkenke, ọ na-akpata site na unyi workpiece na unyi plating ngwọta.

3. Ikuku ọnyá

Ọkpụkpọ ikuku ikuku bụ n'ihi ihe mgbakwunye dị ukwuu ma ọ bụ nnukwu cathode dị ugbu a ma ọ bụ ihe mgbagwoju anya, nke na-ebelata arụmọrụ cathode dị ugbu a ma na-ebute nnukwu evolushọn hydrogen. Ọ bụrụ na ngwọta plating na-agba nwayọọ nwayọọ na cathode ji nwayọọ nwayọọ na-agagharị, gas hydrogen ga-emetụta nhazi nke kristal electrolytic n'oge usoro nke ịrị elu megide elu nke workpiece, na-akpụ ọnyá ikuku site na ala ruo n'elu.

4. Nkpuchi mkpuchi (na-ekpughere ala)

Ihe mkpuchi mkpuchi bụ n'ihi eziokwu ahụ na-ewepụghị ọkụ dị nro na ọnọdụ pin n'elu ọrụ ahụ, na enweghị ike ịme mkpuchi mkpuchi electrolytic ebe a. Enwere ike ịhụ ihe isi ala mgbe electroplating gasịrị, ya mere a na-akpọ ya ekpughere ala (n'ihi na ọkụ dị nro bụ akụkụ translucent ma ọ bụ transperent resin).

5. Mkpuchi brittleness

Mgbe SMD electroplating na ịkpụ na akpụ, a pụrụ ịhụ na e nwere cracking na ehulata nke pin. Mgbe enwere mgbawa n'etiti oyi akwa nickel na mkpụrụ, a na-ekpebi na oyi akwa nickel na-agbaji agbaji. Mgbe enwere mgbawa n'etiti oyi akwa tin na nickel oyi akwa, a na-ekpebi na oyi akwa tin na-agbaji agbaji. Ihe ka ọtụtụ n'ime ihe na-akpata nkụja bụ ihe mgbakwunye, ihe na-egbukepụ egbukepụ, ma ọ bụ ọtụtụ adịghị ọcha na organic na ngwọta plating.
