10 Txheej ENIG FR4 Impedance Control PCB
Vim li cas Tswj Impedance Ntawm PCBs?
Thaum lub teeb liab xav tau ib qho impedance tshwj xeeb los ua haujlwm kom zoo, qhov kev tswj hwm impedance yuav tsum nyiam dua.Hauv cov ntawv thov siv zaus, lub rooj tsav xwm hluav taws xob ua tiav nrog qhov cuam tshuam tas li yog qhov tseem ceeb los tiv thaiv cov ntaub ntawv xa mus los ntawm kev noj nyiaj txiag thiab tswj cov teeb liab kom meej.Lub trajectory ntev dua los yog ntau dua qhov zaus, qhov kev hloov pauv ntau dua yuav tsum tau ua.Txhua qhov tsis muaj kev nruj me ntsis ntawm theem no tuaj yeem ua rau lub sijhawm hloov pauv ntawm cov khoom siv hluav taws xob lossis cov khoom siv hluav taws xob thiab ua rau muaj kev xav tsis thoob.
Thaum cov khoom siv tau nruab rau ntawm lub voj voog, qhov kev tswj tsis tau impedance yog qhov nyuaj rau kev txheeb xyuas.Cheebtsam muaj peev xwm kam rau siab sib txawv nyob ntawm lawv cov batch.Tsis tas li ntawd, lawv cov kev qhia tshwj xeeb yuav raug hloov pauv kub, uas tuaj yeem ua rau tsis ua haujlwm.Nyob rau hauv rooj plaub no, hloov cov khoom siv yuav zoo li kev daws teeb meem thaum xub thawj, tab sis qhov tseeb, qhov tsis tsim nyog kab impedance yog lub hauv paus ntawm qhov teeb meem.
Qhov no yog vim li cas kab impedance thiab nws cov kam rau ua yuav tsum tau kuaj xyuas thaum ntxovPrinted Circuit Board (PCB)tsim.Tus tsim qauv yuav tsum ua haujlwm nrog cov neeg tsim khoom los xyuas kom meej tias tus nqi ntawm cov khoom sib haum.
Cov yam ntxwv ntawm impedance ntawm PCB
PCB nrhiav impedance muaj ob peb yam ntxwv los kawm txog impedance.PCB board tsim impedance muaj xws li: permittivity, ntev, dav, qhov siab, PCB raug txwv / kam rau ua, thiab cov yam ntxwv nyob deb ntawm kev khiav thiab lwm yam tooj liab.
Daim ntawv thov ntawm Impedance Control PCB
Kev tswj hwm impedance suav nrog ntsuas qhov impedance ntawm qee yam kev coj ua thaum lub sijhawm tsim khoom lag luam thiab ua kom ntseeg tau tias nws nyob hauv qhov txwv kev sib txuas lus los ntawm tus tsim qauv.Cov txheej txheem no yog kim, tab sis nws tau dhau los ua kev sib raug zoo txij thaum xyoo 2000s thaum ntxov raws li qhov zaus ntawm cov khoom siv hluav taws xob txuas ntxiv mus ntxiv.Piv txwv li, siv nws hauv cov khoom hauv qab no:
Analog thiab digital telecommunications
Video teeb liab ua
Internet box, TV, GPS, video game, digital koob yees duab
Computers, ntsiav tshuaj, xov tooj
Lub cev muaj zog tswj module
