Cov haujlwm hauv Circuit Board muab ntau txoj hauv kev rau kev kawm, kev nyiam ua haujlwm, lossis tseem tsis raug nqi los tsim cov khoom siv hluav taws xob. Cov haujlwm no tuaj yeem tsim los ntawm cov qauv siv hluav taws xob yooj yim ntawm cov khoom siv perforated board mus rau cov cuab yeej ntse. Cov haujlwm ua haujlwm yooj yim suav nrog lub tswb ntsuas lossis lub qhov rooj kaw, thaum muaj kev cov nyom ntau dua tuaj yeem ua rau oscilloscopes thiab lwm yam khoom siv hluav taws xob siab. Cov muaj kev paub dhau los hauv Circuit Court board ntau lawm tuaj yeem tsim lawv cov laug cam rau cov phiaj xwm tsim tshwj xeeb rau lawv cov kev xav tau.
Cov ntawv luam tawm hauv Circuit Court (PCBs) yog lub hauv paus rau phiaj xwm Circuit Court board. Muaj ntau hom laug ntoo uas tuaj yeem siv tau, nyob ntawm qhov nyuaj ntawm qhov project thiab kev paub ntawm tus neeg siv. Cov laug cam tseeb kuj tuaj yeem tuaj yeem ua ntau yam qauv rau kev ua haujlwm ib ntus lossis mus ib txhis, thiab kev xaiv sim. Cov dej num uas xav tau kev ntsuam xyuas lossis sim yuav tuaj yeem tsim ntawm cov thawj saib xyuas ib ntus, ua ntej cov phiaj xwm tiav.
Lub khob cij yog ib daim qauv ntawm pawg thawj coj ib ntus uas tsis tas siv lub hlau. Nws muaj cov kab rau kev tuav cov khoom hluav taws xob yam tsis muaj kev txuas mus tas li. Cheebtsam tuaj yeem tso rau ntawm lub txiag thiab muab hluav taws xob ua ke. Ib qho zoo ntxiv ntawm hom no yog tias, ntev li ntawm cov khoom tsis tau puas thaum lub sijhawm kuaj cov ntawv, tuaj yeem rov qab siv dua.
