Cov yeeb yaj kiab anti-static npuas puas tuaj yeem muab tso rau ntawm lub rooj tsav xwm Circuit Court
Cov neeg hauv peb lub tuam txhab nyiam muab cov paj yeeb los tiv thaiv zoo li qub (ib daim ntawv nyias txog 30 * 30 hauv yob) hauv qab lub rooj tsavxwm PC. Lawv siv cov npuas dej vim nws pab tiv thaiv lub rooj tsavxwm los ntawm zawv zawg nyob ib puag ncig ntawm qhov chaw ua haujlwm los tiv thaiv zoo li qub, thiab lawv xav tias nws yuav ua rau lub neej ntev ntawm qhov chaw ua haujlwm. Txawm li cas los xij, kuv xav tias qhov no yog kev coj tsis zoo vim tias ua npuas ncauj yog ib qho insulator. Tab sis ntawm qhov tod tes, kuv tau pom tias cov khoom muab tso rau ntawm lub npuas dej (ntawm qhov chaw ua haujlwm saum npoo) tuaj yeem maj mam dissipate lawv cov nqi, raws li kuv qhov kev ntsuas nrog lub ntsuas hluav taws xob electrostatic. Yog li, txoj kev no puas tsim nyog?
kuv teb:
Paj yeeb ua npuas ncauj feem ntau siv tau yog tias nws yog dissipative thiab hluav taws xob hauv av. Tab sis nws yeej nyob ntawm ESD rhiab heev ntawm cov khoom koj xav tiv thaiv.
Txhawm rau ntsuas qhov tsis kam mus rau hauv av (RTG) ntawm cov npuas dej antistatic, koj tuaj yeem siv AAC-TR-800 megohmmeter. Sim ntsuas ntawm 10V thiab 100V. Rau kev nyab xeeb vim li cas, qhov kev tiv thaiv yuav tsum tau tswj ntawm 105 ~ 109 ohms. Koj hais tias koj ntsuas nrog lub ntsuas hluav taws xob electrostatic, uas yog ok, tab sis tsis paub tseeb tias cov npuas dej muaj kev nyab xeeb. Cov txheej txheem tseem ceeb tshaj plaws yog tias qhov chaw ua haujlwm yuav tsum tso tawm tus nqi zoo li qub hauv 100 milliseconds. Yog tias nws siv sijhawm li ob peb feeb kom tshem tawm qhov zoo li qub, qhov ntawd ntev dhau lawm thiab tuaj yeem ua rau koj cov khoom siv ESD rhiab heev ntawm kev pheej hmoo ntawm ESD qhov xwm txheej. Tau kawg, lwm cov ntaub ntawv tseem muaj los tso WIP (ua haujlwm hauv cov txheej txheem) ntawm lub rooj ntev zaum rau kev tiv thaiv zoo li qub thiab cov khoom siv los tiv thaiv tib lub sijhawm. Piv txwv li, anti-static rooj mats yog ib qho kev xaiv zoo heev hauv qhov no.
Qee cov lus nug uas koj yuav tsum paub txog thaum lub sijhawm tswj cov txheej txheem: Dab tsi yog electrostatic rhiab heev ntawm qhov kuv tabtom ua kom tiav ESD tiv thaiv? Puas yog npuas conductivity ntawm ib qho kev nyab xeeb dissipative? Cov npuas puas tuaj yeem tso nws cov nqi hauv li 100 milliseconds? Ua npuas ncauj puas tau grounded? Tus neeg teb xov tooj puas hnav lub dab teg antistatic kom raug? Yog tias tag nrho cov lus nug no yog, ces koj tau ua qee yam kev ceev faj ESD.
