Raws li ib qho tseem ceeb ntawm cov khoom siv hluav taws xob, PCB qhov zoo thiab kev ua haujlwm ncaj qha cuam tshuam rau kev ruaj ntseg thiab kev ntseeg siab ntawm tag nrho cov khoom. Cov txheej txheem kev kho deg ntawm PCB yog ncaj qha ntsig txog cov khoom siv hluav taws xob, kev tiv thaiv corrosion, thiab cov khoom siv hluav taws xob ntawm lub rooj tsav xwm.
Ntawm cov txheej txheem PCB ntau heev, kub plating yog ib txoj kev siv dav. PCB kub plating tsis tsuas yog txhim kho cov conductivity ntawm Circuit Court board, tab sis kuj muaj zoo heev corrosion kuj, thiab tuaj yeem txhim kho kev ntseeg tau ntawm PCB soldering. Kub plating tuaj yeem ua tiav kev sib raug zoo nrog cov khoom siv hluav taws xob, ua kom lub cev ua haujlwm ntawm lub voj voog; Lub caij no, qhov flatness ntawm kub plating txheej tuaj yeem txhim kho kev sib kis ceev ntawm cov teeb liab hluav taws xob thiab txo cov teeb liab sib kis. Kub plating kuj tseem tuaj yeem muab kev tiv thaiv oxidation zoo, txo cov hlau oxidation cov tshuaj tiv thaiv ntawm cov khoom thiab PCBs, yog li txuas ntxiv kev pab cuam lub neej ntawm tag nrho cov khoom siv hluav taws xob.
Hauv PCB kub plating, feem ntau siv cov txheej txheem kub plating xws li kub kub plating, electroplating kub plating, thiab plating ib txheej kub tom qab electroplating kub. Txhua txoj kev nws muaj nws tus yam ntxwv thiab siv scenarios. Kub tseem ceeb kub plating yog tsuas yog siv rau PCBs uas yuav tsum tau muaj kev ntseeg siab dua thiab zoo conductivity, xws li cov khoom siv kev sib txuas lus, cov tub rog aviation khoom, thiab lwm yam. Electroplated kub yog tsuas yog haum rau cov khoom siv hluav taws xob, nrog tus nqi qis thiab cov nyhuv zoo; Electroplated kub ua raws li lwm txheej kub yog siv dav hauv cov khoom siv hluav taws xob. Nws tsis tsuas yog muaj kev ntseeg siab thiab ua tau zoo ntawm cov nyiaj kub kub plating, tab sis kuj muaj tus nqi qis.
Piv nrog PCB kub plating, immersion kub plating, raws li lwm cov txheej txheem kev kho saum npoo, muaj cov ntsiab lus sib txawv thiab cov teebmeem. Hlau deposition yog ua tiav los ntawm cov tshuaj tiv thaiv kom ua tiav cov hlau, tsis zoo li electroplating uas tsis tas yuav siv hluav taws xob tam sim no. Cov txheej kub deposition yog ntau yam sib xws thiab tuaj yeem ua tau zoo sib xws ntawm PCBs ntawm ntau qhov sib txawv. Tus yam ntxwv ntawm sinking kub yog tias nws nto yog smoother, thiab nws muaj zoo hnav tsis kam thiab corrosion kuj. Txawm li cas los xij, piv rau kub plating, tus nqi ntawm cov txheej txheem immersion kub yog qhov siab thiab tsis haum rau txhua qhov kev thov.
Nyob rau hauv cov ntsiab lus, PCB kub plating, raws li ib tug tseem ceeb txheej txheem kev kho mob nto, muaj tej yam yees siv tej yam yees siv uas yuav txhim kho conductivity, corrosion kuj, thiab kev cia siab rau, thiab ntev kev pab cuam lub neej ntawm tag nrho cov Circuit Court board. Nyob rau hauv cov nqe lus ntawm kev xaiv kub plating txoj kev, kub daim ntawv cog lus kub plating yog tsim rau kev ntseeg siab thiab siab conductivity scenarios, electroplating kub yog haum rau cov khoom siv hluav taws xob, thiab electroplating kub nrog lwm txheej kub tom qab electroplating kub tau qis dua thiab siv dav dua. Raws li lwm txoj kev kho deg, immersion kub muaj cov yam ntxwv ntawm flatness thiab corrosion kuj, tab sis nws yog kim thiab tsis haum rau txhua daim ntawv thov scenarios. Xaiv cov txheej txheem kho kom haum rau qhov sib txawv yuav pab txhim kho kev ua tau zoo thiab kev ntseeg siab ntawm cov khoom siv hluav taws xob.
