A kan PCB, ana amfani da nickel azaman rufin ƙarfe don ƙarfe mai daraja da tushe. PCB low-danniya nickel adibas yawanci plated tare da gyara Watt nickel plating mafita da wasu sulfate nickel plating mafita tare da ƙari da cewa rage danniya. Bari ƙwararrun masana'antun su bincika muku waɗanne matsalolin da maganin nickel plating na PCB yakan fuskanta yayin amfani da shi?

1. Tsarin nickel. Tare da yanayin zafi daban-daban, yanayin wanka da ake amfani da shi shima ya bambanta. A cikin nickel plating bayani tare da mafi girma zafin jiki, nickel plating Layer samu yana da low ciki danniya da kuma mai kyau ductility. Ana kiyaye yawan zafin jiki na gabaɗaya a 55 ~ 60 digiri. Idan yawan zafin jiki ya yi yawa, nickel saline hydrolysis zai faru, wanda zai haifar da pinholes a cikin sutura kuma a lokaci guda yana rage polarization na cathode.

2. PH darajar. Ƙimar PH na nickel-plated electrolyte yana da babban tasiri akan aikin shafi da aikin lantarki. Gabaɗaya, ƙimar pH na nickel plating electrolyte na PCB ana kiyaye shi tsakanin 3 da 4. Nickel plating bayani tare da ƙimar PH mafi girma yana da ƙarfi watsawa da ƙarfin halin yanzu na cathode. Amma PH yana da girma sosai, saboda cathode yana ci gaba da haɓaka hydrogen yayin aikin lantarki, lokacin da ya fi 6, zai haifar da pinholes a cikin plating Layer. Maganin nickel plating tare da ƙananan PH yana da mafi kyawun rushewar anode kuma yana iya ƙara abun ciki na gishirin nickel a cikin electrolyte. Koyaya, idan pH yayi ƙasa da ƙasa, za a rage kewayon zafin jiki don samun Layer plating mai haske. Ƙara nickel carbonate ko ainihin nickel carbonate yana ƙara ƙimar PH; ƙara sulfamic acid ko sulfuric acid yana rage ƙimar pH, kuma yana dubawa da daidaita ƙimar PH kowane sa'o'i huɗu yayin aikin.

3. Anode. Tsarin nickel na PCBs na al'ada wanda ake iya gani a halin yanzu duk yana amfani da anodes masu narkewa, kuma abu ne na yau da kullun don amfani da kwandunan titanium azaman anodes don kusurwar nickel na ciki. Ya kamata a sanya kwandon titanium a cikin jakar anode da aka saka da kayan polypropylene don hana laka daga fadawa cikin maganin plating, kuma a tsaftace shi akai-akai kuma a duba ko gashin ido yana da santsi.

4. Tsarkakewa. Lokacin da akwai gurɓataccen ƙwayar cuta a cikin maganin plating, yakamata a bi da shi tare da kunna carbon. Amma wannan hanya yawanci tana cire wani ɓangare na wakili mai rage damuwa (ƙari), wanda dole ne a ƙara shi.

5. Nazari. Maganin plating yakamata yayi amfani da mahimman abubuwan ƙa'idodin tsari da aka ƙayyade a cikin sarrafa tsari. Lokaci-lokaci bincika abubuwan da ke tattare da maganin plating da gwajin kwayar halitta na Hull, da jagoranci sashen samarwa don daidaita ma'auni na maganin plating bisa ga sigogin da aka samu.

6. Tada hankali. Tsarin nickel plating daidai yake da sauran hanyoyin lantarki. Makasudin motsawa shine don hanzarta tsarin canja wurin taro don rage sauye-sauyen maida hankali da kuma ƙara girman iyakar da aka ba da izini na yanzu. Hakanan akwai tasiri mai mahimmanci na motsa maganin plating, wanda shine ragewa ko hana raƙuman ruwa a cikin Layer plating nickel. Yawan matsa lamba iska, cathode motsi da tilasta wurare dabam dabam (hade da carbon core da auduga core tacewa) stirring.

7. Cathode halin yanzu yawa. Girman halin yanzu na Cathode yana da tasiri akan ingancin halin yanzu na cathode, ƙimar ajiya da ingancin shafi. Lokacin amfani da electrolyte tare da ƙananan PH don nickel plating, a cikin ƙananan ƙananan yanki na yanzu, ƙimar halin yanzu na cathode yana ƙaruwa tare da ƙara yawan halin yanzu; a cikin babban yanki mai yawa na yanzu, ingantaccen aiki na yanzu na cathode yana da zaman kanta daga ƙarancin halin yanzu; yayin da ake amfani da PH mafi girma Lokacin da ake amfani da nickel na ruwa, alaƙar da ke tsakanin ingancin cathode na yanzu da ƙarancin halin yanzu ba shi da mahimmanci. Kamar yadda yake tare da sauran nau'in plating, kewayon adadin cathode na yanzu da aka zaɓa don plating nickel shima yakamata ya dogara da abun da ke ciki, zafin jiki da yanayin motsawa na maganin plating.
