Impedans Iimpawu zePCB

Ngokutsho kwethiyori yokuhambisa umqondiso, umqondiso ngumsebenzi wexesha kunye nokuguquguquka komgama, ngoko yonke inxalenye yesignali kumgca ingatshintsha.Ngoko ke, i-AC impedance yomgca wothumelo, oko kukuthi, umlinganiselo wenguqu ye-voltage kwinguqu yangoku, inqunywe njenge-impedance yeempawu zomgca wokuhambisa.

I-impedance yeempawu zomgca wokuhambisa uhambelana kuphela neempawu zoqhagamshelwano lwesignali ngokwayo.Kwisekethe yokwenyani, ixabiso lokumelana nocingo ngokwalo lingaphantsi koxinzelelo olusasaziweyo lwenkqubo, ngakumbi kwisekethe ephezulu yamaza, i-impedance yeempawu ikakhulu ixhomekeke kwi-impedance esasazwayo ebangelwa yiyunithi esasazwayo ye-capacitance kunye neyunithi yokuhanjiswa kwe-inductance. ucingo.

I-impedance yeempawu zomgca wothumelo ofanelekileyo uxhomekeke kuphela kwiyunithi esabelwe amandla kunye neyunithi yokusasazwa kwe-inductance.

Iintlobo ze-Impedans eziqhelekileyo

Ukuphazamiseka kophawu

Kwikhompyuter, unxibelelwano olungenazingcingo kunye nezinye iimveliso zolwazi lwe-elektroniki, amandla athunyelwa kwisekethe ye-PCB sisiginali ye-square wave (ebizwa ngokuba yi-pulse) eyenziwe ngamandla ombane kunye nexesha, kwaye ukuxhathisa okudibana nakho kubizwa ngokuba yi-impedance yeempawu.

Impedance eyahlukileyo

Iifom ezimbini zomqondiso ezifanayo ze-wave wave kunye ne-polarity echaseneyo zigalelo ekupheleni kokuqhuba kwaye zihanjiswe ngemigca emibini eyahlukileyo ngokulandelelana, kwaye izibonakaliso ezimbini ezihlukeneyo zithatyathwa ekupheleni kokufumana.I-impedance eyahlukileyo yi-impedance zdiff phakathi kwemigca emibini.

I-impedance yendlela engaqhelekanga

I-impedance Zo yomnye wemigca emibini emhlabeni iyafana.

Nokuba imowudi impedance

I-impedance ye-zcom yeefom ezimbini ezifanayo ze-wave wave kunye negalelo elifanayo le-polarity ekupheleni kwe-drive xa iingcingo ezimbini zixhunyiwe kunye.

I-impedance yendlela eqhelekileyo

I-impedance Zoe yomnye wemigca emibini ukuya emhlabeni iyafana, edla ngokuba nkulu kune-impedance yemodi engaqhelekanga.
