Lub luag haujlwm tseem ceeb ntawm cov zaus hloov kho lub zog rau hauv PCB cov kev siv hluav taws xob

1.What yog PCB electroplating? 

PCB electropluction yog hais txog cov txheej txheem ntawm kev tso cov txheej txheej ntawm lub pcb mus ua tiav cov hluav taws xob txuas, kev xa mus hluav taws xob, cua sov dissipation, thiab lwm yam haujlwm. Tsoos DC electroplating suffers los ntawm cov teeb meem xws li cov khoom siv tsis zoo, ua kom nws nyuaj rau kev tsim khoom zoo li cov kev sib tw siab tshaj plaws (HDI) thiab hloov cov ntawv sau ua ke (FPC). Kev kub siab hloov pauv cov zog hloov kho AC lub zog rau ACT-zaus rau cov haujlwm ua haujlwm siab thiab lim dej ruaj khov rau qhov chaw nyob ruaj khov. Lawv cov kev ua haujlwm ntau zaus tuaj yeem ncav cuag kaum lossis ntau pua ntawm kiloherrz, deb tshaj lub zog zaus (50 / 60Hz) ntawm cov khoom siv hluav taws xob ib txwm muaj. Qhov kev kub siab no ua tus yam ntxwv coj ob peb qhov zoo rau PCB electroplating.

2.Advantages ntawm high-zaus hloov kho lub zog fais fab hauv PCB electroplating

Txhim Kho Txheej Txheej Txheem Txheej Txheem: "cov nyhuv tawv" ntawm high-zaus ua rau muaj qhov tam sim no ntawm cov neeg saib xyuas kev coj noj coj ua thiab txo cov teebmeem kev sib xws thiab txo cov teebmeem. Qhov no muaj txiaj ntsig zoo tshwj xeeb rau plating cov txheej txheem zoo li cov kab thiab micro-qhov.

Txhim Kho Cov Khoom Siv Paus Muaj Peev Xwm Sib Txawv: cov khoom siv hluav taws xob zoo dua tuaj yeem nkag mus rau hauv qhov, uas ua tau raws li cov kev xav tau sib txawv rau cov kev xav tau zoo.

Nce cov hluav taws xob txuag hluav taws xob: Cov yam ntxwv nrawm hloov kho cov hwj huam hloov pauv ntau dua, txo lub sijhawm thiab nce ntau dua kev ua haujlwm.

Txo kev noj hluav taws xob: Kev siv hluav taws xob siab hloov cov khoom siv hluav taws xob muaj zog hloov kho thiab tsis muaj zog nrog cov qauv ntawm kev tsim khoom ntsuab.

Cov mem tes plating lub peev xwm: kev kub siab hloov kho cov hwj huam yooj yim tuaj yeem yooj yim tso zis pulse txuas ntxiv, ua kom mem tes electropling. Mem tes plating txhim kho cov txheej zoo, nce txheej ntom ntom ntom ntom, txo porosity, thiab minimizes kev siv cov kev sib ntxiv.

3.Enamples ntawm qhov siab tshaj plaws hloov kho cov khoom siv hluav taws xob fais fab hluav taws xob hauv PCB electroplating

A. Tooj plating: Tooj Hluav Taws Xob Cov Hluav Taws Xob Kev Kub Siab Hloov Hloov Rectifiers muab cov txheej ceev tseeb tam sim no, kom txhim kho cov txheej txheem tooj liab tso nyiaj thiab ua kom zoo thiab ua tau zoo ntawm plated txheej.

B. Cov kev kho deg: kev kho saum npoo ntawm PCBs, xws li kub lossis nyiaj plating, kuj yuav tsum muaj lub zog DC ruaj khov. Kev kub hloov pauv hloov kho Rectifiers tuaj yeem muab qhov tseeb tam sim no thiab voltage rau cov khoom siv sib txawv, ua kom muaj kev sib txawv thiab corrosion tsis kam ntawm txheej.

C. Tshuaj Plating: Tshuaj Plating yog nqa tawm yam tsis muaj tam sim no, tab sis cov txheej txheem muaj qhov yuav tsum tau nruj rau qhov ntsuas kub thiab qhov ceev tam sim no. Kev kub hloov pauv hloov kho Rectifiers tuaj yeem muab lub zog rau cov txheej txheem no, pab tswj cov nqi tswj hwm plating.
