Menene PCB Plating?
PCB plating shine tsari na ajiye ƙaramin ƙarfe na bakin ciki a saman saman PCB substrate da hanyoyin gudanarwa. Wannan plating hidima mahara dalilai, ciki har da inganta conductivity na hanyoyi, kare fallasa tagulla saman daga hadawan abu da iskar shaka da lalata, da kuma samar da wani surface for soldering lantarki kayayyakin a kan jirgin. Tsarin plating yawanci ana aiwatar da shi ta hanyar amfani da hanyoyi daban-daban na lantarki, kamar plating mara amfani ko lantarki, don cimma kauri da kaddarorin da aka zana.
Muhimmancin Plating PCB
Sanya PCBs yana da mahimmanci don dalilai da yawa. Da fari dai, yana inganta tafiyar da hanyoyin tagulla, yana tabbatar da cewa siginar lantarki za su iya gudana da kyau tsakanin abubuwan da aka gyara.

Bugu da ƙari, platin yana ba da fili don siyarwa, yana ba da damar kayan aikin lantarki su kasance a haɗe a kan allo, samar da ingantaccen haɗin lantarki.
Nau'in PCB Plating
Akwai nau'ikan plating da yawa da ake amfani da su a masana'antar PCB, kowanne yana da kaddarorin sa da aikace-aikace na musamman. Wasu daga cikin mafi yawan nau'ikan plating na PCB sun haɗa da:
1. Electroless nickel immersion Gold (ENIG): ENIG plating ne yadu amfani a PCB masana'antu saboda da kyau kwarai lalata juriya da solderability. Ya ƙunshi bakin ciki na nickel maras amfani da wutar lantarki wanda ke biye da zinari na nutsewa, yana samar da fili mai laushi da santsi don siyarwa yayin da yake kare tushen jan ƙarfe daga iskar oxygen.
2. Electroplated Zinariya: Electropplated zinariya plating sananne ne don ƙayyadaddun halayensa da juriya ga tarnishing, yana sa ya dace da aikace-aikace inda ake buƙatar babban aminci da tsawon rai. Ana amfani da shi sau da yawa a cikin manyan na'urorin lantarki da aikace-aikacen sararin samaniya.
3. Electroprated Tin: Tin plating ana yawan amfani dashi azaman zaɓi mai tsada don PCBs. Yana ba da kyakkyawar solderability da juriya na lalata, yana sa ya dace da aikace-aikacen maƙasudin gabaɗaya inda farashi ke da mahimmanci.
4. Azurfa mai Wutar Lantarki: Platin Azurfa yana samar da kyakkyawan aiki kuma ana amfani dashi sau da yawa a cikin aikace-aikacen mitoci masu yawa inda amincin sigina yana da mahimmanci. Duk da haka, ya fi dacewa da lalacewa idan aka kwatanta da platin zinariya.
Tsarin Plating
Tsarin plating yawanci yana farawa ne tare da shirye-shiryen kayan aikin PCB, wanda ya haɗa da tsaftacewa da kunna saman don tabbatar da mannewa mai kyau na farantin. Game da plating mara amfani, ana amfani da wankan sinadari dake ɗauke da ƙarfen plating ɗin don saka wani sirara mai bakin ciki akan ma'aunin ta hanyar motsa jiki. A daya hannun kuma, electroplating ya ƙunshi nutsar da PCB a cikin wani bayani na electrolyte da kuma wuce wutar lantarki ta cikinsa don saka karfen a saman.
