Ib nrab Qhov Pcb Nrog Impedance

Ib nrab qhov pcb nrog impedance yog ib qho uas nquag siv cov ntawv luam tawm Circuit Board tsim rau kev sib kis ceev. Qhov kev tsim no tuaj yeem tswj hwm impedance zoo sib xws thaum lub teeb liab kis tau tus mob, xyuas kom ruaj ntseg ntawm cov teeb liab kis tau tus mob, txo cov kev xav tau thiab crosstalk teeb meem thaum lub teeb liab ...

Ib nrab qhov pcb nrog impedance yog ib qho uas nquag siv cov ntawv luam tawm Circuit Board tsim rau kev sib kis ceev. Qhov kev tsim qauv no tuaj yeem tswj hwm qhov cuam tshuam zoo sib xws thaum lub teeb liab kis tau tus mob, xyuas kom muaj kev ruaj ntseg ntawm cov teeb liab kis tau tus mob, txo qhov kev xav tau thiab cov teeb meem sib cuam tshuam thaum lub teeb liab kis tau tus mob, thiab yog li txhim kho kev ua haujlwm ntawm pcb.

Ib qho pcb nrog cov kab impedance feem ntau hu ua impedance board. Feem ntau, ib nrab lub qhov yog tsim rau ntawm ntug ntawm ib qho PCB, thiab ib nrab ntawm lub qhov raug tshem tawm ntawm cov duab ntawm PCB, tsuas yog ib nrab ntawm lub qhov ntawm PCB, feem ntau hu ua ib nrab lub qhov. Lub thiaj li hu ua impedance ib nrab qhov board hais txog lub rooj tsav xwm luam tawm nrog impedance thiab ib nrab qhov tshuab.

Kev siv ib nrab qhov pcb nrog impedance tuaj yeem txhim kho qhov kev sib kis ceev thiab kev ncua deb ntawm lub rooj tsavxwm, tso cai rau cov teeb liab xa mus rau qhov chaw ruaj khov, thiab tsis txhob muaj teeb meem xws li teeb liab attenuation thiab distortion los ntawm impedance mismatch. Tsis tas li ntawd, lub rooj tsavxwm kuj tseem tuaj yeem txo cov theem drift ntawm lub rooj tsavxwm luam tawm, yog li txo lub sijhawm thiab lub moos synchronization teeb meem, thiab ntxiv txhim kho cov teeb liab kis tau tus mob.

Impedance printed circuit boards yuav tsum tau siv cov ntaub ntawv tshwj xeeb thiab cov txheej txheem rau kev tsim khoom. Cov khoom siv feem ntau yog polyimide (PI) thiab epoxy resin (FR-4), uas muaj cov rwb thaiv tsev zoo thiab cov yam ntxwv siab. Cov txheej txheem tsim khoom yuav tsum tau siv cov txheej txheem tshwj xeeb ntawm cov khoom siv rau cov hlau los tswj nws cov impedance.

Nws txais kev tsim tshwj xeeb thiab tsim cov txheej txheem kom tau raws li cov kev xav tau ntawm qee qhov hluav taws xob ntau zaus. Lub ntsiab yam ntxwv ntawm impedance luam ntawv Circuit Court boards yog hais tias lub impedance ntawm lawv cov xov hlau yog tswj nyob rau hauv ib tug tej yam ntau yam los xyuas kom meej qhov tseeb thiab stability ntawm lub transmissions teeb liab.

Ib nrab ntawm lub qhov rooj tuaj yeem pom tau los ntawm lub qhov rooj nrog qhov tshwj xeeb ua tiav aperture. Piv nrog rau qhov tsis tu ncua los ntawm lub rooj tsavxwm lub qhov rooj, qhov kev sib txuas ntawm lub rooj tsavxwm ntawm ib nrab lub rooj tsavxwm yog qhov pub dawb thiab hloov tau yooj yim vim tias nws yog qhov tsis tiav, ua kom yooj yim rau kev tsim teeb meem ntawm PCB thiab txhim kho nws txoj kev ruaj ntseg.

Nyob rau hauv cov txheej txheem ntau lawm ntawm ib nrab qhov luam tawm Circuit Court boards, cov txheej txheem ntawm profileing board yog qhov tseem ceeb, thiab qhov tshwm sim ntawm tooj liab hlau shedding thiab tooj liab tawv lifting feem ntau tshwm sim thaum lub sij hawm board profileing txheej txheem, uas ua rau muaj teeb meem loj rau kev tsim ib nrab ntawm lub qhov rooj. .

Txhawm rau kom ua tau raws li kev xav tau ntawm kev lag luam thiab txuas ntxiv txhim kho cov txheej txheem ntawm impedance ib nrab qhov pcb, thiab kom muaj kev ua tau zoo hauv kev tsim khoom thiab kev tshawb fawb thiab kev tsim kho, Sihui Fuji tau ua tiav zoo tsim 6- txheej impedance ib nrab qhov luam tawm Circuit Court boards φ 0635mm, nws cov teeb liab sab hauv txheej flatness thiab thickness tswj yog heev meej, muab siab impedance raug thiab pom zoo teeb liab-rau-suab nrov piv tswj.

Ib nrab qhov pcb nrog impedance yog ib feem tseem ceeb ntawm niaj hnub luam tawm Circuit Board tsim. Nws qhov tshwm sim tau zoo heev txhim kho kev ua tau zoo thiab kev ntseeg siab ntawm cov ntawv thov kev sib kis ceev, thaum nqa cov thev naus laus zis tshiab thiab cov ntawv thov scenarios rau kev lag luam hluav taws xob.
