Xaiv thiab kev sim cov qauv ntawm ESD anti-zoo li qub txhuam
Cov txhuam hniav uas tawm tsam cov tshuaj tiv thaiv kab mob zoo nkauj uas tau muab faib ua peb hom: Loj, thiab lwm yam, thiab tseem siv tau los txhuam pcb cov laug cam.
Xim txhuam hom txhuam tau muab faib ua ob hom: puag ncig kov, txhua tus muaj cov khoom sib txawv ntawm cov hluav taws xob, pcb cov laug cam, thiab lwm yam.
Hom txhuam kuj tau muab faib ua peb hom: loj, me, uas haum rau kev ntxuav cov laug cam hluav taws xob, thiab lwm yam.
Tshwj xeeb cov txhuam hniav tshwj xeeb yog tsim tshwj xeeb rau qee cov txheej txheem, xws li ntev aluminium anti-zoo li qub txhuam ua rau cov luam ntawv yas.
Yuav:
Kev xaiv ntawm cov muag muag lossis tawv tawv ntawm cov txhuam hniav los txhuam cov khoom yuav tsum txiav txim siab raws li cov kev xav tau ntawm cov khoom siv thiab PCB cov laug cam kom huv si. Yog tias koj ntshai khawb, xaiv ib qho uas tsim cov ntaub muag muag uas haum-brand-nris txhuam, tab sis cov kev ntxuav kom huv yog cov txhuam hniav nyuaj yog qhov zoo dua.
Txoj kev xeem:
) Nto tiv thaiv ntawm txhuam cov plaub hau thiab txhuam kov:
Kev ntsuam xyuas qhov point-to point tsis kam thiab system tiv thaiv hluav taws xob muaj 63 hli Cov khoom sib tiv tauj kawg yog cov roj hmab, hardness 60mmm ± 10mm, thiab nws cov ntim tsawg dua 500 ±: electrode hnyav 2.25 kg? 2.5 kg.
Kev Ntsuas Cov Yuav Tsum Tau Qhia yog muaj nyob rau hauv Table 1.
Thaum kuaj qhov taw tes-rau-cov khoom lag luam tsis kam, cov khoom lag luam (cov khoom siv) yuav tsum muab tso rau ntawm lub rooj insulating lossis muab tso rau hauv lub xeev siv tiag tiag. Qhov saum npoo tsis kam thiab cov ntim tsis kam ntawm lub rooj yog ntau dua 1x10 ^ 13ω muaj feem, thiab nws ntau tshaj 10 cm ntawm cov khoom raug sim. Qhov kev ncua deb ntawm cov electrodes yog 300 hli. Thaum kuaj ntawm hauv av, qhov kev ncua deb ntawm cov electrodes yog 900 hli rau 1000 mm.
Thaum kuaj cov txheej txheem tiv thaiv, qhov kev siv tiag tiag ntawm cov qauv (hauv av) yuav tsum tau kuaj (hauv av yuav tsum tau kuaj. Thaum kuaj engineering, lub electrode yog ntau dua 10 cm ntawm ntug ntawm cov khoom raug sim.
Rooj 1 Kuaj voltages rau sib txawv ranges:
２) triboelectric voltage kuaj:
Siv lub tshuab siv triboelectric los tsim hluav taws xob los ntawm kev sib txhuam, thiab siv cov tsis muaj kev sib kis voltormtion los sim cov triboelectric voltage. Kev sib txhuam ntawm cov tshuab sib txhuam yog cov kab cylindrical, nrog txoj kab uas hla ntawm 50 hli, thiab qhwv nrog ntau dua 1x1o ^ 13 ohms) kom nce kev sib txhuam coefficient (saib daim duab 1). Thaum lub sijhawm ntsuas, pib triboelectric tshuab rau txhuam cov kev sib txhuam tawm tsam cov khoom siv hluav taws xob voltifautures voltical voltageter los ntsuas qhov hluav taws xob voltage nyob rau hauv 10s.
