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. Ntugharị

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, a na-akpata ya site na workpiece ruru unyi na ngwọta plating ruru unyi.

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 na-aga nwayọọ nwayọọ, 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 na ọkụ dị nro dị n'ọnọdụ pin n'elu ọrụ ahụ adịghị ewepụ ya, 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.
