Hauv kev sib txuas lus niaj hnub no, qhov hloov pauv yog ib qho ntawm cov khoom siv uas ua lub luag haujlwm tseem ceeb. Qhov kev ua tau zoo thiab kev ruaj ntseg ntawm kev hloov pauv yog ncaj qha cuam tshuam nrog kev sib txuas lus du thiab cov neeg siv kev paub. Hauv kev tsim cov txheej txheem ntawm kev hloov, PCB tsim yog qhov txuas tseem ceeb.
Ua ntej tshaj plaws, qhov nyuaj ntawm kev tsim ntawm lub rooj tsavxwm hloov PCB yog qhov teeb meem ntawm cov teeb liab cuam tshuam.
Nyob rau ntawm lub rooj tsavxwm PCB, kev tsim thiab kev sib kis ntawm cov teeb liab ceev ceev yuav tsim hluav taws xob ntau dua thiab kev sib nrig sib inductance. Cov hluav taws xob hluav taws xob thiab kev sib nrig sib inductance yuav cuam tshuam nrog lwm cov teeb liab, uas ua rau muaj kev poob qis hauv kev sib txuas lus zoo. Yuav kom daws tau qhov teeb meem no, peb tuaj yeem siv cov tswv yim hauv qab no: Ua ntej, tsim nyog kev npaj ntawm lub teeb liab thiab lub zog hluav taws xob routing txoj kev, kom deb li deb tau los txo qhov kev sib tw; Qhov thib ob, tsim nyog layout thiab siv cov ntaub thaiv npog npog thiab lwm yam kev ntsuas los txo qhov kev sib kis ntawm cov teeb liab cuam tshuam; Thaum kawg, hauv av thiab thaiv hauv av yog tsim nyog tsim los txhim kho qhov txuas ntxiv thiab thaiv cov nyhuv ntawm cov xaim hauv av.
Qhov thib ob, lwm qhov nyuaj ntawm kev hloov PCB tsim yog kev sib kis ntawm cov teeb liab ceev.
Vim lub siab ceev teeb liab zaus ntawm qhov hloov, teeb liab distortion thiab moos deviation yuav tshwm sim nyob rau hauv cov txheej txheem kis tau tus mob. Yuav kom daws tau qhov teeb meem no, peb tuaj yeem siv cov tswv yim hauv qab no: Ua ntej, txais yuav cov kab hluav taws xob zoo dua, xws li cov kab sib txawv sib txawv, txhawm rau txhim kho kev ntseeg tau ntawm cov teeb liab kis tau tus mob; Qhov thib ob, qhov ntev ntawm cov teeb liab kab yog tswj kom tsim nyog kom tsis txhob kis tau tus kab mob qeeb. Thaum kawg, tsim nyog moos synchronization thev naus laus zis tau txais los daws qhov teeb meem ntawm lub moos sib txawv.
Tsis tas li ntawd, qhov hloov pauv PCB tsim kuj tau ntsib nrog cov teeb meem kub dissipation.
Qhov hloov yuav ua kom muaj cua sov ntau thaum lub sijhawm ua haujlwm. Yog tias cov cua kub tsis tuaj yeem ua raws sijhawm, qhov kub ntawm cov khoom yuav siab dhau, thiab tseem cuam tshuam rau kev ua haujlwm ntawm lub cuab yeej. Yuav kom daws tau qhov teeb meem no, peb tuaj yeem siv cov tswv yim hauv qab no: Ua ntej, tsim nyog layout ntawm Cheebtsam thiab cov dab dej kub los txhim kho cov cua sov kom zoo; Qhov thib ob, kev siv cov khoom siv hluav taws xob kub dissipation nplaum, lub dab dej kub thiab lwm yam khoom siv hluav taws xob kub dissipation los ua kom lub tshav kub dissipation cheeb tsam; Thaum kawg, cov khoom siv txias txias xws li cov kiv cua lossis cov pa cua yog siv los txhawb cov cua ncig thiab txhim kho cov cua sov kom zoo.
Nyob rau hauv luv luv, muaj cov kev sib tw nyob rau hauv lub tsim ntawm hloov PCB boards xws li teeb liab cuam tshuam, high-ceev teeb liab kis tau tus mob thiab kub dissipation teeb meem.
