PCB yog ib qho tseem ceeb hauv cov khoom siv hluav taws xob, uas nqa ntau yam khoom siv hluav taws xob thiab muab kev sib txuas hluav taws xob. Hauv kev tsim cov txheej txheem PCB, cov laug cam loj thiab cov laug cam ua lub luag haujlwm tseem ceeb.
Lub rooj tsavxwm siabhais txog PCB pawg thawj coj saib uas muaj ntau txheej txheej, feem ntau tsim nrog 4 txheej lossis ntau dua. Lawv feem ntau yog siv rau hauv cov ntawv thov uas xav tau cov khoom siv hluav taws xob ntau dua thiab kev sib txuas ntau dua, xws li xov tooj ntawm tes, ntsiav tshuaj, thiab cov servers. Piv nrog rau ob sab los yog plaub txheej boards zoo tib yam, high-rise boards muaj ntau lub teeb liab txheej thiab sab hauv cov khaubncaws sab nraud povtseg, uas muaj peev xwm muab ntau qhov chaw thaiv thiab ntau complex circuits. Cov boards siab no kuj muaj peev xwm tiv thaiv kev cuam tshuam zoo dua thiab kev ua haujlwm ntawm hluav taws xob, uas tuaj yeem txhim kho kev ntseeg tau thiab kev ua tau zoo ntawm tag nrho cov tshuab hluav taws xob.
Kev tsim cov txheej txheem ntawm cov vaj huam sib luag siab yog qhov nyuaj, yuav tsum tau ua kom tiav cov txheej txheem siab dua thiab qib kev ua haujlwm. Vim muaj ntau txheej txheej, cov laug cam loj yuav tsum xav txog kev sib cuam tshuam thiab cuam tshuam ntawm cov teeb liab txheej thaum xaim, ua rau kev tsim cov boards siab dua thiab nyuaj. Tsis tas li ntawd, cov nqi tsim khoom ntawm cov laug cam yog qhov siab heev, yuav tsum tau siv sijhawm ntau lawm thiab cov cuab yeej ua haujlwm ntau dua.
Muab piv rau cov boards siab,high-ceev boardmuab qhov tseem ceeb tshaj ntawm cov teeb liab kis ceev thiab ruaj khov. Lawv feem ntau yog siv rau hauv cov ntawv thov uas yuav tsum tau muaj cov teeb liab kis tau tus mob ntau zaus lossis lub moos teeb liab kis tau tus mob, xws li lub khoos phis tawj motherboard, cov khoom siv sib txuas lus, thiab cov ntaub ntawv ceev ceev. High ceev boards yuav tsum tau siab dua teeb liab kev ncaj ncees thiab qis teeb liab poob los xyuas kom meej lub cev kis tau tus mob ntawm high-frequency signals. Yuav kom ua tau raws li cov kev cai no, cov rooj tsav xwm ceev feem ntau siv cov ntaub ntawv tshwj xeeb, kev tsim hluav taws xob, thiab cov txheej txheem tswj impedance.
