Cov khoom siv ntsuas lub tshuab electrostatic yog qhov tseem ceeb ntawm kev tiv thaiv electrostatic
Kuv feem ntau hnov qee cov tuam txhab foundry tuaj sab laj qhov ntsuas thiab hais tias peb lub tuam txhab yog rau cov tuam txhab loj. Lub hom twg thiab cov qauv twg lawv xav kom peb lub tuam txhab siv los ntsuas cov ntsuas hluav taws xob? Vim li cas cov tuam txhab loj xav tau ib qho qauv tshwj xeeb, uas yog, Vim tias qhov tseeb ntawm qee cov cim npe ntsuas tseem ntseeg tau, qhov kev taw qhia kom paub tseeb yog qhov tseeb tom qab ntsuas qhov ntsuas tau, thiab nws yog qhov tseeb thaum saib kev tiv thaiv electrostatic nyob hauv qhov chaw.
Cov khoom lag luam tawm los tiv thaiv kev lag luam yuav tsum tau sim rau ntau qhov ntsuas. Txhawm rau kom ntseeg tau tias cov khoom zoo, cov xaim hluav taws xob tiv thaiv yuav tsum tau ua raws li cov qauv uas xav tau los ntawm cov qauv hauv tebchaws. Qhov yuav tsum ua ntawm cov ntsuas hluav taws xob tiv thaiv kev ua hluav taws xob tsis zoo rau kev tsim cov khoom siv hluav taws xob tsis yog rau kev siv xwb. Qhov saum npoo tsis kam, ntim tsis kam, kev sib txhuam voltage, grounding system tsis kam, lub sijhawm xav tau rau cov khoom siv hluav taws xob tshem tawm thiab sib npaug yog txhua tus nruj, qhov ntsuas tsis dhau tus qauv, thiab electrostatic tiv thaiv yog txhua x Los ntawm lub ntsiab lus no, nws tuaj yeem ua pov thawj tias tseem ceeb npaum li cas lub ntsiab txheeb xyuas tau. Txhua tus paub hais tias txhua yam ntsuas ntsuas ntsuas yog cov lus qhia ntawm yam peb yuav tsum ua. Los yog yuav ua li cas txhawm rau txhim kho khoom zoo lossis chaw ua haujlwm zoo kom tau raws li cov cai ntawm electrostatic tus qauv.
Kev siv tus nqi ntawm anti-zoo li qub kev ntsuas rau kev tsim hluav taws xob kev lag luam:
1. Kev tiv thaiv hluav taws xob hauv av ntawm cov hluav taws xob tiv thaiv zoo li qub qis dua qis dua 10Ω.
2. Los tiv thaiv zoo li qub pem teb los yog pem teb lev: saum npoo tsis kam tus nqi 105-109 voltage, txhuam qhov hluav taws xob<>
3. Anti-zoo li qub phab ntsa: ua hauj tus nqi 5 × 104-109Ω.
4. Anti-static workbench lev: nto tsis kam tus nqi 105-109Ω; txhuam txhuam< 100v;="" tsis="" kam="" rau="" hauv="" av="" txheej="">
5. Qhov kev tawm tsam ntawm kev ua haujlwm los tiv thaiv zoo li qub tig ntsej muag ntawm tus neeg foob yog 105-109Ω.
6. Kev sib txhuam voltage ntawm cov khaub ncaws tiv thaiv zoo li qub ua haujlwm, kaus mom thiab hnab looj tes qis dua 300V; kev txhuam txhuam ntawm cov khau khau yog qhov tsawg dua 100V. Qhov saum npoo tsis kam yog 105-109Ω.
7. Cov tsis kam ntawm cov txuas txuas ntawm kev coj tus cwj pwm tiv thaiv dab tsi yog 1MΩ; thaum lub dab teg pluaj hnav, qhov kev tiv thaiv qhov system yog 750KΩ-10.5MΩ. Cov kev tsis kam ntawm lub pob tw tawv (khau txoj hlua khau) yog 105-108Ω.
8. Cov tsis kam ntawm lub cav logistics lub ntsej muag ntsib lub log log tsheb yog 105-109Ω.
9. Qhov saum npoo tsis kam ntawm cov khoom siv lub thawv, tig lub thawv, PCB khib thiab lwm cov khoom siv thauj khoom siv yog 103-109Ω, thiab qhov kev sib txhuam hluav taws xob tsawg dua 100V.
10. Kev sib txhuam tsis sib haum ntawm cov hnab ntim khoom thiab cov thawv ntim qis dua 100V.
11. Kev tawm tsam tag nrho ntawm tib neeg lub cev yog 105-109Ω.
Nrog rau cov qauv hluav taws xob zoo li saum toj no, cov ntsuas no raug ntsuas los ntawm txhua lub ntsuas hluav taws xob zoo li qub. Yog tias qhov tseeb ntawm qhov ntsuas tsis txaus, lub ntsuas cov ntaub ntawv yuav raug cuam tshuam, tshwj xeeb yog rau qee cov neeg siv khoom uas muaj cov khoom siab rau kev tiv thaiv zoo li qub. Ua cov kev ntsuas ntawm ib puag ncig cov khoom lag luam thiab cov kab tsim cov khoom siv electrostatic, thiab ua kev txhim kho lossis hloov cov khoom siv hluav taws xob yog tias lawv ua tsis tau raws li qhov yuav tsum tau ua.
