Cov qauv siv hluav taws xob cim thiab cov txheej txheem tiv thaiv kev ruaj ntseg
Thaum nws los txog rau hluav taws xob zoo li qub, nws yog ntuj xav txog cov khoom siv coj los tiv thaiv. Hauv cov txheej txheem kev siv tshuaj tiv thaiv, cov hnab looj tes tiv thaiv los tiv thaiv, cov khau tiv thaiv zoo li qub, kev hnav khaub ncaws tiv thaiv thiab lwm cov khoom tiv thaiv tau zoo siv. Hauv chav plua plav dawb tsis muaj teeb meem, tsuas yog qhov xaiv ntawm cov hnab looj tes tiv thaiv thiab lwm cov khoom siv los muab kev pab tiv thaiv zoo.
ESD tau raug tsim los txij thaum nruab nrab ntawm lub xyoo pua no los kawm txog qhov teeb meem thiab qhov teeb meem ntawm cov hluav taws xob muaj hluav taws xob, cov qauv electrostatic tawm, electrostatic tawm cov teebmeem xws li cov hluav taws xob tam sim no (xws li cov hluav taws xob thiab kev sib tsoo los ntawm hluav taws xob muaj hluav taws xob), thiab electromagnetic effects (xws li electromagnetic cuam tshuam). Kawm.
Nyob rau xyoo tas los, nrog rau kev loj hlob sai ntawm kev tshawb fawb thiab kev siv tshuab, kev siv tshuab fais fab kev lag luam thiab qhov chaw chaotic electromagnetic puag ncig, ntau thiab ntau xim tau them rau electromagnetic teb los ntawm electrostatic paug xws li electromagnetic cuam tshuam (EMI) thiab electromagnetic compatibility (EMC). Nws tuaj yeem pom tias qhov kev puas tsuaj ntawm cov hluav taws xob muaj zog loj heev, yog li cov khoom xws li cov hnab looj tes tiv thaiv los tiv thaiv tsis tau yog qhov tsis tsim nyog.
Tus nqi hluav taws xob uas siv los ntawm qhov khoom yog feem ntau qhia los ntawm cov nqi hluav taws xob thiab electrostatic voltage. Cov ntaub ntawv uas raug ntsuas xws li yas, rubber, khoom qub (lub ntsej muag), ntaub pua plag, lwm yam zoo li qub, dielectric qhov, thiab lwm yam. Tab sis feem ntau feem ntau siv thiab feem ntau txhim khu kev qha yog tseem tsis kam thiab resistivity.
ESD tuaj yeem tshwm sim tau vim tias hmoov av nyob hauv cov huab cua sib tsoo thaum sib txav. Yog tias nws tsis ploj lawm, nws nyuaj rau koj hais tias vim li cas rau ESD qhov teeb meem. Cov neeg ncaj ncees vam khom cov khoom siv los tiv thaiv xws li cov plua plav tawm thiab cov hnab looj qes los tiv thaiv, cov khau los tiv thaiv los tiv thaiv qhov teeb meem no. Thawj qhov tseem ceeb yog kom muaj kev pom zoo rau cov plua av, xws li: lub qhov rai xa khoom tsis muaj cua tshuab, qhov chaw da dej hauv chav da dej. Cov neeg ua haujlwm tuaj yeem hnav khaub ncaws hnav zoo li qub.
Qhov thib ob, kom deb li deb tau, tsim kom muaj vaj tse purification, ntxuav chav ntxuav vaj huam sib luag, ntxuav chav xim steel phaj nthab, ntxuav chav xim steel phaj phab ntsa ces kaum, ntxuav chav xim steel phaj sab thiab lwm yam. Kev xaiv ntawm cov khoom siv saum toj no, txhua lub tuam txhab yuav tsum ua raws nraim li cov kev ua ntawm qhov khoom ntawm ESD, qhov zoo tshaj plaws los kawm cov lus txhais ntawm cov kws txuj. Nws tseem ceeb heev uas yuav tsum tsim kom muaj kev sib koom ua tiav tag nrho ESD rau kev ua haujlwm kom muaj kev tiv thaiv ua haujlwm ESD.
Qhov no qhia tau tias tseem ceeb li cas los tiv thaiv cov khoom xws li cov tiv thaiv kev tiv thaiv los tiv thaiv thiab tiv thaiv los tiv thaiv zoo li qub. Txog cov hnab looj tes tiv thaiv los tiv thaiv, txoj kab hlau nrig: 10 hli; sab nraud muaj zog 10 fais fab 7; lub sijhawm electrostatic sijhawm <> nqi them <0.3 μc=""> Cov naj npawb ntawm kev sib txhuam: Ib qib> 100 zaug; B qib> 50. Tom qab xam phaj cov no, peb yuav kho kom zoo dua kom tsis txhob muaj kev puas tsuaj zoo li qub.
