Nyob rau hauv tooj liab cladding, thiaj li yuav ua tau raws li qhov xav tau cov nyhuv ntawm tooj liab cladding, peb yuav tsum tau xyuam xim rau cov teeb meem no: 1. Yog tias muaj ntau lub hauv paus ntawm PCB, xws li SGND, AGND, GND, thiab lwm yam, raws li cov haujlwm sib txawv ntawm PCB nto, qhov tseem ceeb tshaj plaws "hauv av" yog siv raws li kev siv ntawm nws tus kheej npog tooj liab, cov hauv av digital. thiab analog av.Tsis muaj ntau hais txog cov txheej tooj liab sib cais.Nyob rau tib lub sijhawm, ua ntej txheej tooj liab, cov kab hluav taws xob sib txuas ua ntej yog thickened: 5.0V, 3.3V, thiab lwm yam. Nyob rau hauv txoj kev no, ntau yam deformable qauv ntawm cov duab sib txawv yog tsim.

2. Rau ib qho kev sib txuas ntawm qhov sib txawv ntawm qhov sib txawv, txoj kev yog txuas los ntawm 0 ohm tsis kam los yog sib nqus hlaws lossis inductance. 3. Copper cladding nyob ze ntawm lub crystal oscillator.Crystal oscillator nyob rau hauv Circuit Court yog ib tug high-frequency emission qhov chaw.Tus txheej txheem yog clad tooj liab nyob ib ncig ntawm lub siv lead ua oscillator, thiab ces av lub plhaub ntawm lub crystal oscillator cais. 4. Cov kob (zej chaw tuag) teeb meem, yog tias koj xav tias nws loj heev, ces nws yuav tsis raug nqi ntau los txhais ib qho av ntawm thiab ntxiv nws. 5. Thaum pib ntawm kev xaim, cov xaim hauv av yuav tsum tau kho kom sib npaug, thiab cov xaim hauv av yuav tsum tau ua kom zoo thaum routing.Koj tsis tuaj yeem tso siab rau qhov sib ntxiv ntawm vias tom qab txheej tooj liab kom tshem tawm cov pin hauv av rau kev sib txuas.Cov nyhuv no phem heev. 6. Nws yog qhov zoo tshaj kom tsis txhob muaj cov kaum ntse ntse ntawm lub rooj tsavxwm ( 7. Tsis txhob nchuav tooj liab rau hauv qhov chaw qhib ntawm cov xaim hauv nruab nrab ntawm cov txheej txheem ntau txheej.Vim nws yog ib qho nyuaj heev rau koj ua qhov no tooj liab ncuav "zoo av". 8. Cov hlau hauv lub cuab yeej, xws li cov khoom siv hluav taws xob, cov khoom siv hlau, thiab lwm yam, yuav tsum yog "zoo hauv av". 9. Lub tshav kub dissipation hlau thaiv ntawm peb lub davhlau ya nyob twg voltage stabilizer yuav tsum tau zoo grounded.Txoj siv hauv av sib cais nyob ze ntawm cov siv lead ua oscillator yuav tsum muaj av zoo.Hauv ib lo lus: yog tias tooj liab cladding ntawm PCB raug kho kom raug, nws yuav twv yuav raug hu ua "pros outweigh the cons".Nws tuaj yeem txo qhov rov qab ntawm thaj tsam ntawm cov kab teeb liab thiab txo cov electromagnetic cuam tshuam ntawm lub teeb liab mus rau sab nraud.
