Cov Khoom Tshwj Xeeb ntawm Antistatic Shielding Hnab
Feem ntau, cov hnab ntim khoom antistatic lawv tus kheej tsis yooj yim tsim hluav taws xob zoo li qub. Txawm li cas los xij, thaum electrostatic paug (ESD) tshwm sim sab nraum lub hnab ntim khoom, vim lawv qhov kev tiv thaiv tsis zoo tiv thaiv sab nraud ESD, cov khoom siv hluav taws xob hauv lub hnab tuaj yeem cuam tshuam los ntawm ESD sab nraud (electrostatic paug) thiab tej zaum yuav puas. Cov khoom tseem ceeb heev rau hluav taws xob zoo li qub tseem tuaj yeem cuam tshuam.
Piv txwv li, qee lub Hoobkas cov khoom tsim nyog thiab ntim rau hauv cov hnab antistatic ua ntej tawm hauv lub Hoobkas, tab sis thaum tuaj txog ntawm tus neeg siv khoom qhov chaw, qee qhov PCB boards lossis cov khoom siv tau pom tias ua haujlwm tsis zoo. Qhov no yog vim hais tias txawm hais tias ESD ntim hnab nws tus kheej tsis yooj yim tsim hluav taws xob zoo li qub, nws tsis tuaj yeem tiv thaiv ESD sab nraud. Piv txwv li, thaum lub sij hawm thauj mus los, hluav taws xob zoo li qub los ntawm kev tuav cov tshuab tuaj yeem ua rau ESD los ntawm lub tshuab mannequin (MM), thiab hluav taws xob zoo li qub los ntawm lub cev ntawm cov neeg ua haujlwm thauj khoom tuaj yeem ua rau ESD los ntawm tib neeg lub cev mannequin (HBM) lossis hlau mannequin. Yog li ntawd, qhov kev tiv thaiv nto ntawm cov hnab ntim khoom zoo li qub tsis txaus los tiv thaiv ESD sab nraud. Rau cov khoom zoo li no, cov hnab ntim tshuaj tiv thaiv zoo li qub yuav tsum raug xaiv.
Antistatic shielding hnab tsis tsuas yog muaj cov khoom tiv thaiv zoo ntawm txhua lub hnab ntim khoom antistatic, tab sis tseem tiv thaiv ESD (electrostatic paug) thiab hluav taws xob sab nraud los ntawm cov neeg ua haujlwm thiab cov khoom siv. Lawv yog tsim los ntawm ntau cov txheej txheem ntawm cov khoom siv hluav taws xob thiab tiv thaiv - cov khoom siv hluav taws xob thiab feem ntau opaque. Antistatic shielding hnab yog kim dua li cov hnab ntim tshuaj antistatic.
Lawv tuaj yeem siv rau ntim cov khoom siv rhiab uas muaj kev tiv thaiv kev tiv thaiv hluav taws xob thiab hluav taws xob cuam tshuam tseem ceeb.
Lwm yam khoom: Electromagnetic cuam tshuam attenuation, puncture resistance, thiab dej vapor permeability yog tag nrho cov superior rau cov antistatic ntim.
