** EMI shielding yog dab tsi?
EMI, los yog electromagnetic cuam tshuam, yog tshwm sim los ntawm muaj cov electromagnetic teb uas cuam tshuam kev ua haujlwm ntawm cov khoom siv hluav taws xob. EMI shielding yog ib txoj hauv kev los tiv thaiv qhov cuam tshuam no los ntawm kev tsim kev thaiv ntawm cov khoom siv hluav taws xob thiab hluav taws xob hluav taws xob sab nraud. Hauv tsab xov xwm no, peb yuav tham txog qhov tseem ceeb ntawm kev tiv thaiv EMI thiab ntau txoj hauv kev kom ua tiav nws.
** Qhov tseem ceeb ntawm EMI shielding
EMI tuaj yeem ua rau muaj kev cuam tshuam hauv cov khoom siv hluav taws xob, ua rau muaj kev ua haujlwm tsis zoo thiab ua haujlwm tsis zoo. Nws tuaj yeem cuam tshuam nrog kev sib txuas lus thiab ua rau cov ntaub ntawv poob. Hauv cov ntawv thov tseem ceeb xws li cov cuab yeej kho mob, aviation, thiab tub rog tshuab, EMI tuaj yeem ua rau muaj kev phom sij rau lub neej. EMI shielding yog, yog li ntawd, tseem ceeb heev rau kev ua haujlwm kom raug thiab kev nyab xeeb ntawm cov khoom siv hluav taws xob.
** Cov peev txheej ntawm EMI
EMI tuaj yeem tsim los ntawm cov khoom siv ntuj tsim los yog tib neeg tsim. Qee qhov chaw ntawm EMI suav nrog:
1. Cov hluav taws xob hluav taws xob los ntawm lub hnub
2. xob laim
3. Cov kab hluav taws xob
4. Xov tooj cua thiab TV
5. Cov khoom siv wireless xws li xov tooj ntawm tes, Wi-Fi routers, thiab Bluetooth li
6. Cov khoom siv xws li hluav taws xob motors thiab transformers
** Cov txheej txheem tiv thaiv EMI
Muaj ntau txoj hauv kev kom ua tiav EMI shielding, suav nrog:
1. Cov khoom siv hluav taws xob tiv thaiv
Cov khoom siv hluav taws xob xws li tooj liab, txhuas, thiab hlau feem ntau yog siv rau EMI shielding. Lawv tsim ib qho kev thaiv ntawm cov khoom siv hluav taws xob thiab cov hluav taws xob hluav taws xob sab nraud los ntawm kev cuam tshuam cov hluav taws xob tam sim ntawd los yog nqus nws.
2. Sib nqus shielding
Sib nqus shielding yog ua tiav los ntawm ib puag ncig cov khoom siv hluav taws xob nrog cov khoom sib nqus xws li hlau. Cov khoom siv hlau nplaum tsim ib qho chaw sib nqus uas tawm tsam sab nraud electromagnetic tawg.
3. Absorptive shielding
Absorptive shielding siv cov ntaub ntawv uas nqus hluav taws xob electromagnetic. Cov ntaub ntawv no muaj xws li carbon-filled ua npuas ncauj, ferrite, thiab conductive polymers.
4. Electromagnetic cuam tshuam cov ntxaij lim dej
Electromagnetic cuam tshuam cov ntxaij lim dej yog cov khoom siv hluav taws xob uas tau muab tso rau hauv Circuit Court ntawm cov khoom siv hluav taws xob los lim tawm cov kev cuam tshuam electromagnetic.
** Cov yam tseem ceeb uas yuav tsum xav txog thaum xaiv txoj kev tiv thaiv EMI
Thaum xaiv txoj kev tiv thaiv EMI, ntau yam yuav tsum tau xav txog, suav nrog:
1. Qhov ntau zaus ntawm cov hluav taws xob hluav taws xob hluav taws xob
2. Hom khoom siv hluav taws xob
3. Tus nqi ntawm kev tiv thaiv yuav tsum tau
4. Ib puag ncig uas yuav siv lub tshuab hluav taws xob
5. Tus nqi ntawm cov ntaub thaiv npog thiab kev teeb tsa
** Lus xaus
EMI shielding yog qhov tseem ceeb hauv kev ua kom muaj kev ua haujlwm zoo thiab kev nyab xeeb ntawm cov khoom siv hluav taws xob hauv ntau qhov kev lag luam. Muaj ntau txoj hauv kev kom ua tiav EMI shielding, thiab kev xaiv ntawm txoj kev tsim nyog nyob ntawm ntau yam. Los ntawm kev tiv thaiv kev cuam tshuam los ntawm cov hluav taws xob hluav taws xob sab nraud, EMI shielding ua kom muaj kev ntseeg siab, kev ua tau zoo, thiab kev nyab xeeb ntawm cov khoom siv hluav taws xob.
