ESD txhais li cas? Puas yog hais txog kev siv hluav taws xob zoo li qub?
ESD sawv cev rau "electrostatic discharge" thiab nws cov lus Askiv yog: Tshaj tawm ntawm Electro-Static. Txij li thaum xyoo pua 20th, kev qhuab qhia rau txoj kev kawm ntawm tiam, kev tsim txom, thiab hluav taws xob tiv thaiv hluav taws xob hauv hluav taws xob tau raug hu ua ESD. Tus txheej txheem ntawm ESD yog kev hloov ntawm electrostatic tsub nruab nrab ntawm cov khoom ntawm ntau qhov peev xwm. Kev siv ntawm nws cov nyiaj pab cuam tshuam los ntawm tus nqi hluav taws xob thiab qhov ze ntawm cov khoom.
Nyob rau hauv lub chaw nyob, xob laim yog qhov tshwm sim ESD raws li muaj kev nyab xeeb kev nyab xeeb. Nws tso loj zog hauv ib qho instant. Nws muaj peev xwm ionize cov huab cua uas cov hluav taws xob dhau los, thiab nws yuav ua rau cov huab cua ib tug tsawg-lead conductive channel, sib sau ib tug haib tam sim no thiab high kub. Nws lub hwj chim puas yuav tsum tsis txhob poob siab.
Qhov tseeb tiag, cov cuab yeej tiv thaiv ESD yog tag nrho hu ua ESD hauv lub ntiaj teb. Lub npe Suav hu ua electrostatic ua hauj lwm, uas txhais tau hais tias kev ceev nrawm ntawm kev them nyiaj. Peb paub tias tag nrho cov khoom muaj xws li cov atoms, thiab electronons thiab protons muaj nyob rau hauv cov atoms. Thaum ib qho khoom ua rau los sis los ntawm electrons, nws poob nws qhov hluav taws xob tshuav thiab ua tsis zoo los yog them zoo. Txo cov khoom zoo lossis tsis zoo ntawm qhov khoom ntawm cov khoom yuav ua rau cov khoom yuav ua rau lub hwjchim uas tsis muaj nuj nqi. Lub Hoobkas ESD tswj kev ua haujlwm tsis muaj dab tsi ntau tshaj li kev yuav khoom ntawm cov khaub ncaws ua hauj lwm los tiv thaiv qis thiab lub dab teg, cov khoom siv ESD yooj yim, thiab muaj qhov sib txawv ntawm ESD20.20 tus qauv. ANSI / ESD S20.20, tus txheej txheem yog tus txheej txheem Asmesliskas, tab sis nws nyob rau hauv North America, Europe, thiab Asia.
