Ua ntej ntawm tag nrho, as a luam tawm Circuit Board , PCB feem ntau muab kev sib txuas ntawm cov khoom siv hluav taws xob.Tsis muaj kev sib raug zoo ntawm cov xim thiab kev ua haujlwm, thiab qhov sib txawv ntawm cov pigments tsis cuam tshuam rau cov khoom hluav taws xob.

Cov kev ua tau zoo ntawm cov PCB pawg thawj coj saib yog txiav txim los ntawm tej yam xws li cov khoom siv (siab Q tus nqi), kev tsim thaiv, thiab ob peb txheej ntawm lub rooj tsavxwm.Txawm li cas los xij, hauv cov txheej txheem ntawm kev ntxuav PCB, dub yog qhov feem ntau yuav ua rau muaj xim sib txawv.Yog tias cov khoom siv raw thiab cov txheej txheem tsim khoom siv los ntawm lub Hoobkas PCB muaj qhov sib txawv me ntsis, tus nqi ntawm PCB yuav nce vim qhov sib txawv xim.Qhov no ncaj qha ua rau kev nce hauv cov nqi tsim khoom.

Hauv Qhov tseeb, cov ntaub ntawv raw ntawm PCB muaj nyob txhua qhov chaw hauv peb lub neej niaj hnub, uas yog, iav fiber ntau thiab cob.Cov iav fiber ntau thiab cov resin sib xyaw ua ke thiab ua kom tawv tawv los ua cov cua sov-insulating, insulating, thiab tsis yooj yim rau khoov board, uas yog PCB substrate.Tau kawg, PCB substrate ua los ntawm iav fiber ntau thiab resin ib leeg tsis tuaj yeem ua cov teeb liab.Yog li ntawd, ntawm PCB substrate, cov chaw tsim tshuaj paus yuav npog ib txheej ntawm tooj liab rau saum npoo, yog li PCB substrate kuj tseem hu ua tooj liab-clad luam ntawv Circuit Court board.

Raws li cov kab hluav taws xob ntawm cov PCB dub yog qhov nyuaj rau kev txheeb xyuas, nws yuav ua rau kom qhov nyuaj ntawm kev kho thiab kev debugging nyob rau hauv R & D thiab tom qab-muag theem.Feem ntau, yog tias tsis muaj cov khoom lag luam nrog cov neeg tsim khoom RD (R&D) zoo thiab pab pawg saib xyuas muaj zog, PCBs dub yuav tsis yooj yim siv.Nws tuaj yeem hais tias kev siv cov PCB dub yog lub hom phiaj kev ntseeg siab hauv RD tsim thiab pab pawg tom qab tu.Ntawm qhov tod tes, nws kuj yog ib qho kev tshwm sim ntawm cov neeg tsim khoom kev ntseeg siab ntawm nws tus kheej lub zog.

Raws li ntawm cov laj thawj saum toj no, cov tuam txhab loj yuav ua tib zoo xav txog thaum xaiv PCB tsim rau lawv cov khoom.Yog li ntawd, feem ntau ntawm cov khoom nrog loj xa khoom nyob rau hauv lub lag luam xyoo ntawd siv liab PCB, ntsuab PCB, los yog xiav PCB versions.Dub PCBs tsuas yog pom ntawm nruab nrab-rau-siab-kawg lossis cov khoom lag luam saum toj kawg nkaus, yog li tsis txhob ntseeg tias cov PCBs dub zoo dua li ntsuab.
