ESD txhuam kom pom tseeb
Tshuaj tiv thaiv zoo li qub muag ntawm lub khw yuav tsum muab faib ua peb hom: loj, nruab nrab, thiab me me. Lawv tsim nyog rau tu ntau yam hauv hluav taws xob, PCB boards, thiab lwm yam, thiab tseem tuaj yeem siv PCB cov laug cam.
Kev txhuam txhuam txhuam hniav yog muab faib rau hauv: tuav kab, sib tsoo ob, txhua yam uas muaj qhov loj ntawm cov ntsiab lus, tsim los tu ntau yam khoom hauv hluav taws xob, PCB pawg thawj coj thiab lwm yam.
U-puab txhuam kuj tau faib rau: loj, nruab nrab thiab me me peb, tsim los kho tu lub tshuab hluav taws xob, PCB Board, thiab lwm yam.
Zoo li tus txhuam txhuam tshwj xeeb uas tsim los rau qee lub txheej txheem, xws li ntev txhuas txhuas los ntawm kev txhim kho rau cov yas luam yeeb.
Purchase:
Kev sib txhuam los ntawm kev txhuam hniav thiab cov xaiv nyuaj, yuav tsum tau ua raws li cov PCB cov khoom kom tau muab ntxuav los txiav txim siab txog qhov yuav tsum tau ua, rau kev ntshai raug khawb ntawm kev siv cov plaub muag plaub hau, tab sis qhov kev txhuam ntawm kev txhuam nyuaj.
Txoj Kev Xeem:
1) Cov pob txha tsis ua hauj lwm thiab txhuam kov ntsa tawv:
6 Kev sim tshuaj
6.1 Taw tes rau Taw Qhia Qhov Taw thiab Kuaj Tiv Thaiv Zog
Electrode qauv siv: kem electrode inch 63 hli ± 3 hli: cov khoom siv electrode yog hlau tsis muaj kauv lossis tooj liab; electrode hu rau cov khoom siv roj hmab, qhov 60 ± 10 (Shore A qib), thickness 6mm ± 1mm, lub ntim ua haujlwm tsawg dua 500Ω: Qhov hnyav electrode yog 2.25 kg? 2.5 kg.
Thaum ntsuas qhov taw qhia-rau-taw kev, qhov khoom (khoom) yuav tsum tau muab tso rau ntawm ib qho insulating nto lossis tso rau hauv lub xeev qhov kev siv. Mesa ntom nti tsis ua haujlwm thiab ntim tsis ua haujlwm ntau dua li 1 x 10 ^ 13Ω, feem ntau, thiab lawv geometrical perimeter qhov loj tshaj cov khoom ntsuas 10 cm. Qhov kev ncua deb ntawm cov electrodes yog 300 hli. Hauv kev sim hauv av, qhov deb ntawm electrodes yog 900 mm txog 1000 hli.
Thaum kuaj qhov system ua haujlwm tsis zoo, txoj kev kuaj coj (hauv av) yuav tsum tau sim rau kev siv. Thaum lub sij hawm kev ntsuam xyuas engineering, lub electrode yog ntau tshaj 10 cm deb ntawm ntug ntawm cov khoom nyob rau hauv kev xeem.
2) Txhuam kom tsis muaj teeb meem hluav taws xob:
Cov kev sib txhuam ntawm kev sib txhuam los yog siv rau kev sib txhuam thiab qhov tsis sib chwv ntawm lub tshuab electrostatic voltage tau siv los ntsuas qhov kev siv hluav taws xob hluav taws xob. Kev sib txhuam hluav taws xob ntawm kev sib txhuam kev sib tw yog nyob rau hauv ib lub voj voog, muaj ib txoj kab uas muaj 50 mm mus txog 60 hli, ib qhov hnyav ntawm 1 kg, lub ntim ua rau ntau tshaj 1 x ^ 13 ohms, thiab ntaub ntim cov ntaub (piv rau daim duab 1): Thaum lub sij hawm qhov kev ntsuam xyuas, pib txhuam cov tshuab kev sib txhuam los ntawm kev txhuam cov hluav taws xob los ntawm cov khoom ntsuas, thiab qhov kev sib txhuam tsis sib npaug tau nres 20 zaug (zaug) sijhawm 20s), thiab qhov kev sib txhuam ntawm qhov kev sib txhuam ntawm kev sib txhuam tau ntsuas nrog ib hom non-contact type electrostatic voltmeter hauv 10 s.
