Cov xwm txheej ntawm kev siv ion kiv cua hauv high-tech manufacturing
Ib qho kev hloov pauv ntawm cov cuab yeej siv hluav taws xob ntawm cov kiv cua ion yuav cuam tshuam rau kev tswj cov khoom siv hluav taws xob zoo li qub hauv kev tsim cov khoom siv high-tech. Kev tswj cov hluav taws xob zoo li qub yog lub hauv paus rau kev txhim kho kev tsim khoom, kev txhim kho kom zoo thiab nce cov txiaj ntsig. Hauv kev tsim khoom ntawm semiconductors, hard disks thiab vaj huam sib luag tiaj tus (FPDs), electrostatic tswj yog ib qho ntawm cov txheej txheem tsim khoom. Kev tswj tsis tau hluav taws xob zoo li qub txhais tau hais tias cov khoom raug kev txom nyem los ntawm cov kab mob ionic loj (ESA teeb meem) thiab electrostatic paug (ESD teeb meem) tshwm sim los ntawm electrostatic attraction.
Cov koom haum xws li ESD Association thiab Semiconductor Equipment and Materials International muaj cov txheej txheem tswj zoo li qub uas tshem tawm cov teeb meem zoo li qub. Txoj kev tseem ceeb ntawm qhov no yog siv cov khoom siv hluav taws xob zoo li qub thiab cov khoom siv hluav taws xob zoo li qub (xws li tib neeg lub cev) kom ncaj qha mus rau lub ntiaj teb kom dissipate hluav taws xob zoo li qub. Txawm li cas los xij, ob qho tib si cov khoom nws tus kheej thiab ib puag ncig ua haujlwm inevitably siv cov ntaub ntawv insulating.
Thaum rwb thaiv tsev yog qhov tseem ceeb ntawm cov khoom siv nws tus kheej, koj tsis tuaj yeem hloov nws. Piv txwv li, silicon wafers nrog oxide txheej yog siv nyob rau hauv kev tsim khoom ntawm high-tech khoom, ib leeg-conductor li encapsulated nyob rau hauv epoxy resins, insulating cov ntaub ntawv ntawm ntaus ntawv pins, epoxy luam Circuit Court boards, thiab iav nplooj nyob rau hauv FPDs kev lag luam. Tsis tas li ntawd, Teflon, quartz, thiab ntau cov ntaub ntawv yas yog qhov kub thiab txias, corrosion resistant, thiab cleanroom tau tshaj, tab sis lawv yog tag nrho cov ntaub ntawv insulating. Grounding tsis tshem tawm cov nqi hluav taws xob zoo li qub ntawm cov ntaub ntawv insulating, yog li feem ntau cov kev xaiv uas tseem tshuav yog nruab nrab nrog huab cua ionization. Qhov no yuav tsum tau siv cov cuab yeej tshwj xeeb static tshem tawm.
