Yuav tsum ntxuav cov khaub ncaws zoo li cas?
Tom qab cov plua plav tsis pub dawb, cov khaub ncaws ua hauj lwm yuav siv ncaj qha rau kev cob qhia ntau plua plav. Nyob rau hauv qhov chaw ua yeeb yam uas muaj cov cuab yeej ua tiav, muaj kev txawv txav hauv ib qhov txuas yuav ua rau qhov khoom siv zaum kawg. Yog tias cov hmoov av ntawm cov khaub ncaws ua haujlwm tshaj li ntawm kev tswj ntau, lawv yuav poob rau hauv qhov chaw tsis muaj plua plav vim tias tus neeg hnav tuaj sab nrauv. Cov khoom no yuav muaj lub sijhawm los poob rau qhov khoom kawg. Cov khaub ncaws huv yog qhov tseem ceeb ntawm thaj chaw tsis muaj hmoov av. Nws tseem ceeb heev uas yuav tau saib xyuas nws.
▲ Kev ntsuam xyuas ESD
ESD kev ua tau zoo yog qhov tseem ceeb rau kev ntsuam xyuas cov hauj lwm khaub ncaws. Qhov kev ntsuam xyuas dav dav ESD muaj plaub ntu: kev sib txheeb ntawm kev ntsuas kev sib txhuam, kev sib tw uas tsis muaj zog, kev sim ua haujlwm, thiab kev lwj sijhawm.
Kev sib txhuam ntawm qhov kev sib tw
Qhov kev sim no tsuas yog los xyuas seb qhov ntaub npog nws tus kheej thiaj ncav cuag ib qho kev txiav txim siab ruaj khov nyob rau hauv ib lub sij hawm luv luv tom qab accumulating ib co voltage tom qab txhuam. Qhov no yog qhov tseem ceeb los xyuas qhov zoo ntawm cov xov tooj hluav taws xob.
* Kev ntsuam xyuas ntawm kev sib tw ntawm ESD (hauv av), lub tester rubs lub npoo ntawm npuag ntau zaus (feem ntau 5-10 zaug) nrog qee yam quab yuam thiab ceev, thiab tom qab ntawd cais cov kev sojntsuam uas muaj lub siab ntsig txog . Dlhos qhov rubbed tshooj ib ncig ntawm 5 cm thiab nyeem qhov value ntawm voltage tom qab thib 5th thib ob.
* Cov qauv kev xeem, cov kev cai ntawm cov khaub ncaws ESD hauv kev lag luam kev lag luam yog tsawg dua 100V. Qee qhov kev lag luam muaj cov qauv nyav, xws li wafer thiab hau lag luam, thiab kev sib tw tsis sib haum yog feem ntau tsawg dua 20V.
Qhov kev ntsuas ntawm qhov muaj teeb meem zoo li qub
Qhov kev kuaj no yog xyuas kom paub ntau npaum li cas cov ntaub npog nws tus kheej tuaj yeem nyob ntawm tus xov tooj hluav taws xob tom qab txuag tau qee lub zog ntawm hluav taws xob hauv qhov chaw.
* Kev ntsuam xyuas, muab cov khaub ncaws khi rau ntawm ib qho kev xeem tshwj xeeb, thiab siv ESD tester's sojntsuam los nyeem cov nqi hluav taws xob txog 5CM.
Cov qauv kev xeem, nyob ntawm tus txheej txheem tsim ntawm tus neeg siv cov khaub ncaws ua haujlwm, qhov tseem ceeb tshaj plaws yuav tsum tau ua dua 5V. Feem ntau, nws muaj ntau tshwm sim ntawm thaj tsam 50V.
Qhov dej sim tsis txaus
Qhov kev kuaj no qhia qhov hluav taws xob siv hluav taws xob thiab cov txheej txheem ntawm cov txheej txheem ntaus ntawv ua ntej ntaub npuag thiab ntaub qhwv, xws li kev sib txuas ntawm cov yeeb yaj kiab hluav taws xob.
* Kev kuaj kev kuaj, hnav cov khaub ncaws ua haujlwm ntawm lub rooj sib tw tshwj xeeb, sim nws nrog cov tshuaj tua tsis sib haum, feem ntau yuav tsum tau sim cov ntsiab lus ntawm cov khaub ncaws ua haujlwm, xws li daim ntaub, nruab nrab ntawm cov ntaub qhwv ntaub, tsho caj dab thiab ntawm lub tes tsho, nruab nrab ntawm lub ris thiab lub ris.
* Cov qauv kev xeem, raws li cov qauv ntawm kev lag luam ntawm kev lag luam, feem ntau cov tuam txhab tswj kev tiv thaiv ntawm cov khaub ncaws ua hauj lwm ntawm 105-109 ohms, thiab tseem tau teem cia ntawm 105-107.
▲ Decay sijhawm
Qhov kev sim yog qhov tseem ceeb kom paub tseeb tias ntev npaum li cas cov ntaub ntawm cov ntaub qhwv tuaj yeem faib lub siab kom qis qis dua qis dua tom qab lub siab siv.
Feem ntau cov fabrics muaj tsawg lub sijhawm ntawm tsawg dua 0.5 feeb, nyob ntawm tus neeg muas zaub.
