Dab tsi yog impedance hauv PCB board?

Thaum nws los txog rau impedance, ntau tus engineers muaj ntau yam teeb meem nrog nws.Vim tias muaj ntau qhov sib txawv uas cuam tshuam rau tus nqi ntawm kev tswj impedance hauv lub rooj tsavxwm luam tawm, txawm li cas los xij, dab tsi yog impedance thiab peb yuav tsum xav txog dab tsi thaum tswj impedance?

Lub ntsiab txhais ntawm Impedance?

Impedance yog qhov sib npaug ntawm qhov tsis kam thiab reactance ntawm hluav taws xob Circuit Court uas ntsuas hauv Ohms.Impedance yog ib qho kev hloov pauv tam sim no uas cov teeb liab zaus yog ib qho tseem ceeb.Qhov ntev ntawm txoj kab los yog qhov ntau dua, qhov tseem ceeb tshaj nws yuav tsum tswj cov kab impedance.Lub teeb liab zaus yog qhov tseem ceeb tshaj plaws rau cov kab uas txuas mus rau cov khoom uas xav tau ob mus rau peb puas MHz lossis ntau dua.
Ntau cov kab sib txawv yuav raug siv rau hauv cov ntawv luam tawm hauv Circuit Court kom ua tiav cov kev tswj xyuas impedance.Peb tuaj yeem tswj cov impedance los ntawm qhov sib nrug thiab qhov ntev ntawm cov kab hluav taws xob hauv Circuit Court.

Impedance Control Level muaj

Feem ntau, muaj peb theem ntawm impedance tswj muaj rau luam tawm Circuit Boards.

1. Impedance Tswj
Impedance tswj tau dav siv nyob rau hauv high-end designs nrog ib tug nruj kam rau ua los yog txawv configuration.Muaj ntau ntau hom kev tswj impedance.Nyob rau hauv uas tus yam ntxwv impedance yog siv.Lwm hom muaj xws li yoj impedance, duab impedance, thiab input impedance.

2. Impedance Saib
Impedance Saib txhais tau hais tias kev sib raug zoo hauv impedance.Lub impedance tswj kab yuav raug txiav txim siab los ntawm qhov dav ntawm kab thiab qhov siab ntawm dielectric, uas tuaj yeem hloov kho raws li qhov xav tau.

3. Tsis muaj impedance tswj
Vim tias qhov impedance kam rau ua hauv kev tsim tsis nruj, qhov tseeb impedance tuaj yeem ua tiav los ntawm kev ua raws li tus qauv tshwj xeeb yam tsis muaj impedance tswj.qhov tseeb impedance tuaj yeem muab los ntawm PCB cov chaw tsim khoom yam tsis muaj cov kauj ruam ntxiv, Yog li, nws yog qib zoo tshaj plaws.

Qhov tseem ceeb ntawm qhov tseeb rau kev tswj impedance

Qhov tseem ceeb ntawm qhov tseeb yog qhov tseem ceeb heev rau kev tswj hwm impedance boards ua haujlwm kom raug.vim hais tias PCB designers yuav tsum tau qhia cov kab impedance thiab kam rau ua yuav tsum tau.

Cov lus nug ntxiv txog kev tswj hwm impedance, koj tuaj yeem sab laj nrog pab pawg kws tshaj lij hauv PHILIFAST, lawv yuav muab cov kev daws teeb meem zoo tshaj plaws rau koj txog koj cov PCB boards.
