6 Txheej FR4 ENIG Impedance Control PCB
Vim li cas PCB thiaj Ua Impedance?
PCB impedance yog hais txog qhov tsis kam thiab qhov tsis kam ntawm qhov reactance, uas ua raws li qhov cuam tshuam rau qhov hloov pauv tam sim no.Kev ua haujlwm impedance yog qhov tseem ceeb hauv PCB.Nov yog vim li cas:
1, PCB los txiav txim siab lub plug installation ntawm cov khoom siv hluav taws xob, SMT patch plug kuj yuav tsum tau xav txog cov khoom siv hluav taws xob thiab cov teeb liab kis tau tus mob, yog li nws yuav xav tau qhov qis impedance, zoo dua.
2, PCB nyob rau hauv cov txheej txheem ntau lawm los ntawm tooj liab deposition, electroplating tin (los yog electroless plating, kub tshuaj tsuag tin), connector soldering thiab lwm yam txheej txheem, cov ntaub ntawv siv yuav tsum tsis tshua muaj resistivity, los xyuas kom meej tias tag nrho impedance tus nqi ntawm lub Circuit Court board kom tau raws li. cov khoom yuav tsum tau ua kom zoo, thiaj li yuav ua haujlwm zoo.
3, PCB tin plating yog qhov feem ntau muaj teeb meem hauv tag nrho PCB ntau lawm, yog qhov txuas tseem ceeb cuam tshuam rau impedance;Nws qhov loj tshaj qhov tsis xws luag yog yooj yim oxidation los yog deliquesce, tsis zoo brazing, yog li ntawd lub PCB yog ib qho nyuaj rau weld, impedance siab dhau lawm, ua rau tsis zoo conductive kev ua tau zoo los yog tag nrho cov PCB kev ua tau zoo tsis ruaj khov.
4, tus neeg xyuas pib hauv PCB yuav muaj ntau yam teeb liab kis tau tus mob, kab nws tus kheej vim etching, lamination thickness, hlau dav thiab lwm yam, yuav ua rau impedance tus nqi hloov, ua rau lub teeb liab distortion, ua rau kev ua tau zoo ntawm lub Circuit Court. board poob, yog li nws yog ib qho tsim nyog los tswj tus nqi impedance nyob rau hauv ib qho kev sib txawv.
