1.What is PCB Electroplating?
PCB electroplating yana nufin tsarin ajiye wani Layer na karfe akan saman PCB don cimma haɗin lantarki, watsa sigina, zubar da zafi, da sauran ayyuka. Traditional DC electroplating yana fama da batutuwa irin su rashin daidaituwar sutura, rashin isasshen plating, da tasirin gefen, yana mai da wahala a iya biyan buƙatun masana'anta na PCBs masu ci gaba kamar allunan Haɗaɗɗen Maɗaukaki (HDI) da Sassauƙan Bugawa (FPC). Matsakaicin sauyawar wutar lantarki yana canza wutar lantarki ta mains AC zuwa babban mitar AC, wanda sai a gyara shi kuma a tace don samar da tsayayyen DC ko halin yanzu. Mitar aikin su na iya kaiwa dubun ko ma ɗaruruwan kilohertz, wanda ya zarce mitar wutar lantarki (50/60Hz) na kayan wutar lantarki na gargajiya na DC. Wannan sifa mai girma-mita yana kawo fa'idodi da yawa ga PCB electroplating.

Ingantacciyar Rufin Uniformity: "Tasirin fata" na igiyoyin ruwa mai yawa yana haifar da halin yanzu don maida hankali kan saman madubin, inganta ingantaccen sutura da rage tasirin gefen. Wannan yana da amfani musamman don sanya hadaddun sifofi kamar layi mai kyau da ƙananan ramuka.
Ingantacciyar Ƙarfin Rubutun Zurfi: Matsakaicin igiyoyi masu ƙarfi na iya mafi kyawun kutsawa ga bangon rami, haɓaka kauri da daidaituwar plating a cikin ramuka, wanda ya dace da buƙatun plating don babban yanayin rabo ta hanyar.
Yawan ingantaccen aiki: Halayen mai sauri na Canjin Ikon Zaman Lafiya na yanzu, yana rage lokacin shirya kayan aiki da haɓaka haɓaka.
Rage Amfani da Makamashi: Manyan kayan wutar lantarki masu sauyawa suna da ingantaccen juzu'i da ƙarancin amfani da makamashi, daidai da yanayin masana'antar kore.
Pulse Plating Capability: Babban mitar sauya wutar lantarki na iya fitar da mai bugun jini cikin sauƙi, yana ba da damar wutar lantarki. Pulse plating yana inganta ingancin sutura, yana ƙaruwa da yawa, yana rage porosity, kuma yana rage yawan amfani da ƙari.
3.Misalan Babban-Frequency Canja Wuta Power Supply Applications a PCB Electroplating
A. Copper Plating: Copper electroplating Ana amfani da PCB masana'antu don samar da conductive Layer na kewaye. Masu gyara jujjuyawar mitoci masu tsayi suna ba da madaidaicin yawa na halin yanzu, yana tabbatar da jibgewar yumɓun tagulla iri ɗaya da haɓaka inganci da aikin farantin.
B. Surface Jiyya: Surface jiyya na PCBs, kamar zinariya ko azurfa plating, kuma na bukatar barga DC ikon. Masu gyaran gyare-gyare masu mahimmanci na iya samar da daidaitattun halin yanzu da ƙarfin lantarki don nau'o'in plating daban-daban, tabbatar da santsi da juriya na lalata.
C. Chemical Plating: Ana yin platin sinadarai ba tare da halin yanzu ba, amma tsarin yana da ƙaƙƙarfan buƙatu don zafin jiki da yawa na yanzu. Matsakaicin gyare-gyaren gyare-gyare masu mahimmanci na iya samar da wutar lantarki don wannan tsari, yana taimakawa wajen sarrafa ƙimar plating.
4.Yadda ake tantance PCB Electroplating Power Supply Specifications
Ƙayyadaddun ƙayyadaddun wutar lantarki na DC da ake buƙata don PCB electroplating sun dogara ne akan abubuwa da yawa, ciki har da nau'in tsarin lantarki, girman PCB, yanki na plating, buƙatun yawa na yanzu, da ingantaccen samarwa. A ƙasa akwai wasu maɓalli masu mahimmanci da ƙayyadaddun wadatar wutar lantarki gama gari:
A.Tallafikan Yanzu
●Yawan halin yanzu: Yawan halin yanzu don PCB electroplating yawanci jeri daga 1-10 A/dm² (ampere da murabba'in decimeter), dangane da electroplating tsari (misali, jan karfe plating, zinariya plating, nickel plating) da kuma shafi bukatun.
●Jimlar Buƙatun Yanzu: Ana ƙididdige jimillar abin da ake buƙata a halin yanzu bisa yankin PCB da yawa na yanzu. Misali:
Idan PCB plating yanki ne 10 dm² da halin yanzu yawa ne 2 A/dm², jimlar halin yanzu da ake bukata zai zama 20 A.
Don manyan PCBs ko samarwa da yawa, ana iya buƙatar amperes ɗari da yawa ko ma mafi girma na yanzu.
Matsakaicin Na yau da kullum:
●Ƙananan PCBs ko amfani da dakin gwaje-gwaje: 10-50 A
●Matsakaicin girman PCB samarwa: 50-200 A
● Manyan PCBs ko samar da taro: 200-1000 A ko mafi girma
B.Voltage Specificities
⬛ PCB electroplating gabaɗaya yana buƙatar ƙananan ƙarfin lantarki, yawanci a cikin kewayon 5-24 V.
⬛ Buƙatun ƙarfin lantarki sun dogara da dalilai kamar juriya na wanka mai ɗorewa, nisa tsakanin na'urorin lantarki, da tafiyar da wutar lantarki.
⬛Don ƙwararrun matakai (misali, ƙwanƙwasa bugun jini), ana iya buƙatar manyan kewayon ƙarfin lantarki (kamar 30-50 V).
Yawan Wutar Lantarki na gama gari:
● Standard DC electroplating: 6-12 V
●Pulse plating ko na musamman matakai: 12-24 V ko mafi girma
Nau'in Samar da Wutar Lantarki
● DC Power Supply: An yi amfani da shi don na'urar lantarki na DC na gargajiya, yana ba da kwanciyar hankali da ƙarfin lantarki.
● Petsewar wutar lantarki: amfani don bugun jini, mai iya haifar da babban-mitar da aka soke igiyoyi don inganta ingancin shirya.
Mitawar Canza Wutar Wutar: Babban inganci da amsa mai sauri, dace da ingantaccen bukatun lantarki.
C.Power Supply Power
Ƙarfin wutar lantarki (P) yana ƙayyade ta halin yanzu (I) da ƙarfin lantarki (V), tare da dabara: P = I × V.
Misali, wutar lantarki da ke fitar da 100 A a 12 V zai sami ikon 1200 W (1.2 kW).
Yawan Wutar Wuta:
● Ƙananan kayan aiki: 500 W - 2 kW
●Matsakaicin kayan aiki: 2 kW - 10 kW
● Manyan kayan aiki: 10 kW - 50 kW ko mafi girma
