1. Muaj ntau cov teeb meem uas peb yuav tsum tau them sai sai rau thaum kho hluav taws xob hluav taws xob. Ua ntej, wb nkag siab txog cov teeb meem tseem ceeb uas yuav tsum tau them nyiaj rau hauv cov nqe lus ntawm xaim dav. Vim yog cov neeg hloov pauv tam sim no tau tsim tawm ntawm cov kab ntawv PCB ntawm PCB Circuit Board, qhov cuam tshuam cuam tshuam tsuas yog tshwm sim los ntawm kev siv hluav taws xob feem ntau yog cov luam xov hlau. Yog li ntawd, qhov tsis pom zoo ntawm cov xov hlau luam tawm yuav tsum tau txo qis ntau li ntau tau. Txais txoj kev qhia kom raug thiab siv cov kev sib luag sib luag tuaj yeem txo cov kev sib luag ntawm cov hlau, tab sis nce kev sib nrig sib luag thiab faib hluav taws xob ntawm cov xov hlau. Yog tias cov txheej txheem tso cai, nws yog qhov zoo tshaj plaws kom siv tus ntoo khaub lig zoo li cov qauv siv hlau. Cov qauv tshwj xeeb yog los tso cov kab xov kab tav toj ntawm ib sab ntawm cov ntawv luam tawm thiab ntsug rau sab tod, thiab tom qab ntawd txuas nrog cov qhov ntawm tus ntoo khaublig.
2. Vim tias cov teeb meem kev nplua nuj ntawm PCB Circuit Coal xas, txhawm rau txhawm rau tshem tawm cov hluav taws xob ntev li ntau li ntau tau thaum lub sij hawm tsim qauv. Cov paib kab laum, kab hauv av, thiab cov kab hluav taws xob yuav tsum tsis txhob hla kom ntau li ntau tau. Teeb tsa cov kab ntawv sau ua haujlwm nruab nrab ntawm qee cov teeb liab kab uas muaj kev nkag siab yooj yim los cuam tshuam tuaj yeem ua tau zoo rau kev nkag siab ntawm kev sib tshuam.
3. Hauv kev saib xyuas cua txias ntawm cov tshuab cua txias, lub hauv paus ntsiab lus yooj yim ua ntej thiab qhov nyuaj tom qab yuav tsum tau ua raws. Ua ntej tshaj, kos lub zog Circuit Court thiab rov pib dua Crystal oscillator, tom qab ntawd xyuas cov chaw taws teeb tswj hwm kev lag luam, thiab thaum kawg hloov CPU. Vim tias hloov ntau lub CPU pins yog qhov nyuaj tshaj plaws thiab kim, thiab tsis muaj qhov tshwm sim yooj yim, yog li tsis yooj yim hloov CPU hauv cov microcomputer tswj Circuit Court.
