1.PCB Electroplating yog dab tsi?
PCB electroplating yog hais txog cov txheej txheem ntawm kev tso ib txheej ntawm cov hlau mus rau saum npoo ntawm PCB kom ua tiav kev sib txuas hluav taws xob, teeb liab kis tau tus mob, cua sov dissipation, thiab lwm yam haujlwm. Kev lig kev cai DC electroplating raug kev txom nyem los ntawm cov teeb meem xws li txheej txheej tsis zoo, tsis txaus plating qhov tob, thiab cov teebmeem ntawm ntug, ua rau nws nyuaj rau kev ua kom tau raws li cov kev xav tau ntawm cov PCBs siab heev xws li High-Density Interconnect (HDI) boards thiab Flexible Printed Circuits (FPC). Cov khoom siv hluav taws xob ntau zaus hloov pauv lub zog AC lub zog mus rau qhov siab AC, uas yog tom qab ntawd kho thiab lim kom tsim cov DC ruaj khov lossis cov khoom siv hluav taws xob. Lawv cov kev khiav hauj lwm zaus tuaj yeem ncav cuag kaum lossis ntau pua kilohertz, nyob deb tshaj lub zog zaus (50/60Hz) ntawm cov khoom siv hluav taws xob DC ib txwm muaj. Cov yam ntxwv siab zaus no coj ntau qhov zoo rau PCB electroplating.
2.Qhov zoo ntawm High-Frequency Switching Power Supplies hauv PCB Electroplating

Qhov no yog tshwj xeeb tshaj yog pab tau rau plating complex lug xws li nplua kab thiab micro-qhov.
Txhim khu kev sib sib zog nqus plating muaj peev xwm: High-frequency tam sim no tuaj yeem nkag mus rau hauv lub qhov phab ntsa zoo dua, ua kom tuab thiab sib xws ntawm plating hauv qhov, uas ua tau raws li cov kev xav tau plating rau qhov zoo sib piv vias.
Ua kom Electroplating Efficiency: Cov lus teb ceev ceev ntawm cov khoom siv hluav taws xob ntau zaus ua kom muaj kev tswj xyuas tam sim no ntau dua, txo cov sij hawm plating thiab ua kom cov khoom ua tau zoo.
Kev siv hluav taws xob txo qis: Cov khoom siv hluav taws xob hloov pauv ntau zaus muaj kev hloov pauv siab thiab kev siv hluav taws xob tsawg, ua raws li cov qauv ntawm kev tsim ntsuab.
Pulse Plating Capability: High-frequency switching power supplies can easy output pulsed current, enabling pulse electroplating. Pulse plating txhim kho txheej txheej zoo, ua kom cov txheej txheej ntom ntom, txo qhov porosity, thiab txo qis kev siv cov khoom ntxiv.
3. Piv txwv ntawm High-Frequency Switching Power Supply Applications hauv PCB Electroplating
A. Copper Plating: Copper electroplating yog siv hauv PCB tsim los tsim cov txheej txheem conductive ntawm Circuit Court. High-frequency switching rectifiers muab qhov ceev ceev tam sim no, kom ntseeg tau tias cov txheej txheem tooj liab tsis sib xws thiab txhim kho qhov zoo thiab kev ua haujlwm ntawm cov txheej plated.
B. Kev Kho Ntog: Kev kho deg ntawm PCBs, xws li kub lossis nyiaj plating, kuj yuav tsum muaj zog DC ruaj khov. High-frequency switching rectifiers tuaj yeem muab qhov tseeb tam sim no thiab qhov hluav taws xob rau cov hlau sib txawv, kom ntseeg tau tias smoothness thiab corrosion kuj ntawm txheej.
C. Chemical Plating: chemical plating yog nqa tawm yam tsis muaj tam sim no, tab sis cov txheej txheem muaj cov kev cai nruj rau qhov kub thiab txias tam sim no. High-frequency switching rectifiers tuaj yeem muab lub zog pabcuam rau cov txheej txheem no, pab tswj cov nqi plating.
4.Yuav txiav txim siab PCB Electroplating Power Supply Specifications
