Dab tsi yog qhov txaus ntshai ntawm kev siv cov tais hlau thaum tuav cov khoom siv hluav taws xob
Dab tsi yog qhov txawv ntawm kev siv lub tais stainless hlau thiab cov khoom siv hluav taws xob dub xws li lub tais tiv thaiv zoo li qub uas ob qho tib si muaj kev tiv thaiv qis dua 1x10^4 [ohms]? Dab tsi yog qhov txaus ntshai ntawm kev siv cov tais hlau thaum tuav cov khoom siv hluav taws xob? Kuv puas tuaj yeem muab cov txheej txheem ua npuas dej rau ntawm lub tais hlau rau cov khoom siv zoo li qub?
Conductive txhais tau hais tias muaj qhov chaw tiv thaiv hauv qab 1x10^4 ohms. Vim hais tias thaum lub nto ntawm ib yam khoom yog conductive heev, ib tug nyob twj ywm tau yooj yim tso tawm (ib qho kev tshwm sim electrostatic paug) thaum nws los rau hauv kev sib cuag nrog ib tug conductive nto, txawm nws yog grounded los yog tsis. Qhov no yog qhov kev hem thawj ntawm tus qauv ntaus ntawv.
Nws tau teev nyob rau hauv tus qauv hais tias qhov kev tiv thaiv qis dua 2.2x10 ^ 3 ohms yuav ua rau muaj qhov tshwm sim ESD vim qhov tsis muaj zog. Lub tais stainless hlau muaj qhov ua haujlwm zoo hauv qab 1 ohm thiab muaj qhov cuam tshuam rau CDM ESD qhov xwm txheej, qhov uas cov khoom siv hluav taws xob dub tuaj yeem muaj qhov tsis kam rau hauv av ntau dua 2.2x10^3 ohms thiab tsis tshua muaj kev phom sij, txawm li cas los xij, nws tseem yog tuaj yeem ua rau qhov kev tshwm sim CDM ESD.
ESD-ADV53.1 Cov Khoom Siv Hluav Taws Xob: Cov khoom siv hauv chaw ua haujlwm yuav tsum txuas nrog rau hauv av nrog cov hluav taws xob txuas ntxiv raws li hauv qab no:
Ua hauj lwm nto kuj: ntawm 1 x 10^6 ohms thiab 1 x 10^9 ohms;
Txee thiab tub rau khoom nto tiv thaiv rau cov khoom siv tsis muaj kev tiv thaiv ESD: 1 x 10^6 ohms thiab 1 x 10^9 ohms;
Cov neeg ua haujlwm hauv av taw tes tsis kam: tsawg dua 1 ohm;
Kev them nyiaj yug Structure Resistance: Tsawg dua 1 ohm
Koj tuaj yeem nteg ib txheej ntawm cov npuas dej ntawm cov khoom zoo li qub rau ntawm lub tais hlau kom txo tau qhov kev pheej hmoo ntawm kev raug rau lub tais ntawm cov khoom siv hluav taws xob, lossis ntim cov cuab yeej rau hauv lub hnab tiv thaiv zoo li qub thaum khaws cov khoom rhiab rau ntawm cov khoom siv hluav taws xob. Los ntawm kev tso cov khoom siv dissipative ntawm lub tais thiab lub cuab yeej yuav ua rau lub zog hloov mus qeeb thiab txo txoj kev pheej hmoo ntawm ESD kev tshwm sim. Tau kawg, koj kuj tseem xav tshawb xyuas qhov tuab ntawm cov khoom siv hluav taws xob zoo li qub ua ntej siv, vim tias cov txheej txheem static dissipative nyias dhau lawm, thiab qhov ntim tsis kam yuav tsawg dhau los muab kev tiv thaiv.
