Nws tsis nyuaj kawm PCB tsim. Lub software tsuas yog ib qho cuab yeej. Yog tias koj muaj lub hauv paus computer, koj tuaj yeem kawm paub siv PCB software hauv ob lub lis piam. Qhov tseem ceeb yog nkag siab txog hluav taws xob hluav taws xob, cov lus qhia me me tuaj yeem yuav qee cov vis dis aus qhia hauv Is Taws Nem, lawv tus kheej lub sijhawm tshwj xeeb thaum kawm thaum ua haujlwm, kiv cua Billion video yog qhov zoo, xaiv cov khoom haum rau lawv tus kheej.

Hais txog PCB, ntau tus phooj ywg yuav xav tias nws tuaj yeem pom txhua qhov nyob ib puag ncig peb, los ntawm txhua yam khoom siv hauv tsev, txhua yam khoom siv hauv khoos phis tawj mus rau txhua yam khoom lag luam digital, tsuav yog cov khoom siv hluav taws xob yuav luag txhua siv PCB, yog li PCB yog dab tsi lub ntiaj teb? PCB yog PrintedCircuitBlock, uas yog daim ntawv luam tawm Circuit Board rau cov khoom siv hluav taws xob kom muab tso rau. Cov phaj tooj liab tooj liab tau luam tawm thiab tshem tawm ntawm cov hluav taws xob sib dhos.

PCB tuaj yeem muab faib ua ib leeg, ob chav thiab ntau pawg. Txhua yam khoom siv hluav taws xob tau muab tso rau hauv PCB. Ntawm ib qho yooj yim ib txheej PCB, cov ntu tau tsom mus rau ntawm ib sab thiab cov xov hlau tau tsom mus rau lwm qhov. Yog li peb yuav tsum ua qhov nyob rau hauv lub rooj tsavxwm kom cov pins tuaj yeem hla lub rooj tsavxwm mus rau lwm sab, yog li cov pins ntawm ntu tau txuas rau lwm sab.

Vim li no, sab pem hauv ntej thiab sab nraub qaum ntawm cov PCB no hu ua ib feem ntawm qhov chaw thiab qhov chaw sib txuas ua ke. Cov txheej txheem txheej ob txheej tuaj yeem pom ua ob txheej txheej txheej sib koom ua ke, nrog cov khoom siv hluav taws xob thiab txuas rau ob sab ntawm lub rooj tsavxwm. Qee lub sij hawm nws yog qhov tsim nyog los txuas ib lub xov hlau los ntawm ib sab mus rau lwm sab ntawm pawg thawj coj los ntawm cov lus qhia. Phau ntawv qhia qhov yog qhov me me hauv PCB uas tau ntim lossis coated nrog cov hlau uas tuaj yeem txuas nrog cov xov hlau ntawm ob sab. Tam sim no, ntau lub khoos phis tawj niam txiv siv 4 lossis txawm tias 6 txheej ntawm PCB, thaum daim npav daim npav feem ntau siv 6 txheej PCB. Ntau daim npav duab siab kawg zoo li nVIDIAGeForce4Ti series siv 8 txheej PCB, uas yog hu ua ntau txheej PCB. Qhov teeb meem ntawm kev txuas kab ntawm cov txheej kuj tseem ntsib ntawm ntau txheej PCBS, uas tseem tuaj yeem ua tiav los ntawm kev qhia qhov.

Vim tias muaj ntau txheej PCB, qee zaum phau ntawv qhia tsis tas yuav nkag mus rau tag nrho PCB. Cov lus qhia qhov no hu ua faus qhov thiab qhov dig muag qhov vim tias lawv tsuas nkag mus rau ob peb txheej. Qhov muag tsis pom txuas ob peb txheej ntawm PCBS sab hauv rau saum PCBS yam tsis nkag mus rau tag nrho lub rooj tsavxwm. Cov qhov faus tsuas yog txuas rau sab hauv PCB, yog li lub teeb tsis pom los ntawm qhov chaw. Hauv ntau lub PCB, txhua txheej tau txuas ncaj qha mus rau hauv av xaim thiab lub zog hluav taws xob.

Yog li peb faib txhua txheej raws li txheej txheej, txheej fais fab lossis txheej av. Yog tias cov ntu ntawm PCB xav tau cov khoom siv sib txawv, feem ntau lawv muaj ntau dua ob lub zog thiab cov txheej hlau. Qhov ntau txheej PCB koj siv, tus nqi ntau dua. Tau kawg, siv ntau txheej txheej ntawm PCBS pab muab teeb liab ruaj khov.
