Muaj pes tsawg hom ESD tiv thaiv cov khoom lag luam
Cov khoom lag luam zoo li qub tau muab faib ua plaub pawg: tib neeg lub cev tiv thaiv kev tiv thaiv zoo li qub, khoom siv hluav taws xob zoo li qub, cov ntsuas khoom zoo li qub thiab cov cuab yeej zoo li qub.
1. Cov tswv yim yooj yim rau kev tiv thaiv ESD dav dav
(1) Los ntawm qhov pom ntawm kev tsim qauv, kev tiv thaiv electrostatic yog tsim rau hauv cov khoom siv hauv LED, xws li muaj lub zog siab ntawm LED. Tus neeg tsim qauv tsim qauv electrostatic tiv thaiv diodes ntawm flip-chip silicon wafers nqa GaN-based LED chips. Lub sijhawm no, cov silicon wafers tsis tsuas yog ua raws li GaN Cov neeg nqa khoom tseem muaj lub luag haujlwm ntawm kev tiv thaiv ESD, kom cov cuab yeej ESDS ntim nrog cov nti no tuaj yeem ncav cuag ntau txhiab volts. Nws qhov kom zoo dua yog qhov txhim kho ncaj qha rau anti-ESD muaj peev xwm ntawm lub cuab yeej, ua kom yooj yim rau txoj kev tiv thaiv electrostatic tiv thaiv hauv cov txheej txheem ntawm cov ntim ntau lawm thiab cov khoom ntim; qhov tsis zoo yog tias nws ua rau tus nqi nce ntxiv, nce ntim, cov txheej txheem tsim ntau lawm yog ib qho nyuaj thiab yuav tsum muaj cov cuab yeej ua haujlwm ntau lawm. Nws yog qhov tsim nyog rau cov khoom muaj nqis-siab LED.
(2) Ntawm qhov pom ntawm cov txheej txheem ntau lawm, muaj ob txoj hauv kev tiv thaiv electrostatic;
① Tshem tawm cov khoom thiab txheej txheem uas tsim hluav taws xob zoo li qub. Los ntawm kev xaiv ntawm cov khoom siv, txoj hauv kev ntawm hluav taws xob hluav taws xob tiam yog tshem tawm lossis txo qis, thiab tiam thiab kev txuam nrog kev tshem tawm zoo li qub yog tshem tawm los ntawm lub hauv paus. Nws yog ib qho ntawm cov txiaj ntsig yooj yim ntawm kev tiv thaiv hluav taws xob zoo li qub.
Ntws lossis tso tawm kom tiv thaiv electrostatic tawm. Vim tias txhua txoj hauv kev los tsim hluav taws xob zoo li qub tsis tuaj yeem raug tshem tawm tag nrho, peb yuav tsum muaj kev nyab xeeb los yog tso tawm hluav taws xob zoo li qub uas yuav tshwm sim los tiv thaiv qhov tshwm sim ntawm hluav taws xob zoo li qub.
2. ESD electrostatic tiv thaiv grounding tshuab
Grounding yog kom ncaj qha tawm hluav taws xob zoo li qub mus rau hauv av los ntawm xaim txuas. Nov yog qhov ua kom ncaj dua thiab siv tau cov qauv ntawm los tiv thaiv kev ua zoo li qub. Cov nyhuv ntawm cov tshuab hluav taws xob tiv thaiv feem ntau nyob ntawm qhov zoo ntawm cov xaim hluav taws xob hauv av. Electrostatic grounding tshuab yog qhov sib txuas tseem ceeb hauv cov txheej txheem paug electrostatic. Qhov zoo ntawm lub system grounding yuav ncaj qha cuam tshuam qhov paug muaj peev xwm ntawm lub txim. Cov kab hlau hauv av yuav tsum muaj peev xwm lees txais lossis muab tus nqi ntau rau. Lub xaim hluav taws xob zoo tshaj plaws yuav tsum muaj tus coj tus cwj pwm zoo, uas yog, tsis muaj qhov tshwm sim poob thaum qhov tam sim no ntws los ntawm cov av hlau, thiab lub peev xwm ntawm txhua lub ntsiab lus ntawm cov kab hlau hauv av yog tib yam. Lub pob hluav taws xob zoo li qub hauv thaj chaw ua haujlwm yuav tsum yog cov xaim hluav taws xob hauv av rau hluav taws xob zoo li qub, thiab tsis tuaj yeem sib koom nrog lwm cov xov hluav taws xob hauv av. Anti-static grounding yog ib qho ntawm qhov ntsuas tseem ceeb hauv cov phiaj xwm kho vaj tse ntoo.
3. ESD electrostatic tiv thaiv kev ua haujlwm
Thaum ua haujlwm ntawm electrostatic rhiab khoom siv, ib lub rooj noj mov anti-static lub rooj ua los ntawm cov ntaub ntawv nrog electrostatic conductivity thiab electrostatic dissipation cov haujlwm yuav tsum muab tso rau ntawm haujlwm. Ua kom txhua qhov chaw nres tsheb, twj, twj, thiab tib neeg lub cev sib txuas nrog lub cuab yeej ncav cuag lub peev xwm zoo sib xws, thiab hauv av hluav taws xob zoo li qub kom tso tawm sai sai.
4. Anti-static system rau tib neeg lub cev
Tib neeg lub cev tiv thaiv kev tiv thaiv zoo li qub yog tsim los ntawm kev tiv thaiv zoo li qub dab teg, tiv thaiv khaub ncaws ua haujlwm zoo li qub, khau, thiab lwm yam, thiab thaum tsim nyog, nws yuav tsum tau muab ntxiv nrog lub ntsej muag tiv thaiv kev ua haujlwm, hnab looj tes, ko taw npog thiab lwm yam khoom. Qhov hom no tsis tseem ceeb tiv thaiv kev tiv thaiv hluav taws xob muaj qhov haujlwm ntawm kev tso hluav taws xob zoo li qub, kev tso nruab nrab thiab kev tiv thaiv. Los tiv thaiv zoo li qub dab teg pluaj yog ua los ntawm cov khoom siv hluav taws xob, uas tuaj yeem ua hluav taws xob zoo li qub mus ntawm tib neeg lub cev los ntawm kev sib chwv tawv nqaij ncaj qha. Yog li no, txoj hlua tes yuav tsum muaj kev sib cuag zoo rau cov tawv nqaij thaum siv nws, yog li ntawd qhov hluav taws xob ceev me me ntawm daim tawv nqaij tsawg dua 100V. Tus thawj coj ua haujlwm lub rooj zaum siv cov khoom siv electrostatic conductive ua cov ntaub. Lawv tsis tsim hluav taws xob zoo li qub nyob rau hauv kev sib cuag nrog tib neeg, thiab tuaj yeem tawm cov hluav taws xob zoo li qub ntawm tib neeg lub cev, ua rau lub ntiaj teb, thiab ua si lub luag haujlwm ntawm kev tiv thaiv hluav taws xob zoo li qub.
5. Kev tiv thaiv ESD thaum lub sijhawm khoom tsim
Cov txheej txheem ntau lawm ntawm LED los ntawm chip rau pob ntawv thov yog qhov nyuab dua. Txog rau kev tiv thaiv zoo li qub, nws yog cov txheej txheem kev kho mob dav dav. Nws yuav tsum nkag mus rau txhua qhov txuas ntawm kev tsim khoom, thiab raws li cov txheej txheem cov cai ntawm txhua qhov txuas ntau lawm, cov khoom siv sib txawv yuav tsum tau ua kom tau txais qhov ua tau zoo ntawm kev tiv thaiv electrostatic ntawm lub cuab yeej. Cov txheej txheem cov cai rau txhim kho ib qho khoom siv (xws li tuag tsev cog khoom, chaw nres tsheb sib khi, khoom siv kuaj, khoom siv tes ua yoj, thiab lwm yam):
(1) Txhua lub cuab yeej yuav tsum muaj av zoo;
(2) Nws yog qhov tsim nyog los nruab cov lev anti-static nyob ib ncig ntawm txhua cheeb tsam;
(3) Tus tswj hwm hnav cov ris tsho tiv thaiv zoo li qub, lub kaus mom, pluaj dab teg, thiab lwm yam.;
(4) Yog tias tsim nyog, teeb tsa kiv cua ion ntawm qhov tseem ceeb ntawm kev tiv thaiv zoo li qub.
6. Ion kiv cua
Cov rwb thaiv tsev nquag rau cov hluav taws xob zoo li qub. Cov hau kev teeb tsa tsis tuaj yeem tshem tawm hluav taws xob zoo li qub ntawm cov rwb thaiv tsev. Cov nyhuv ntawm ions feem ntau yog siv los nruab nrab hluav taws xob zoo li qub ntawm cov khoom siv insulating. Ion blower yog ib qho cuab yeej uas ua rau lub tshuab pa tawm ntawm ionized. Nws yog siv los nruab nrab txhua qhov kev tsub nqi ntawm cov ntaub ntawv insulating thiab muab cov khoom ua haujlwm hauv chaw ua haujlwm.
7. Lwm qhov kev tiv thaiv rau ESD tiv thaiv
(1) Thaum kuaj GaN-based LEDs, ntxiv rau hauv av ntawm lub ntsuas, nws tseem yuav tsum nkag siab qhov kev ntsuas ntawm cov ntsuas, tshwj xeeb tshaj yog qhib lub xov tooj cua ntawm lub zog muab rau cov ntsuas tas mus li.
(2) Lub rooj qhia tau hluav taws xob zoo li qub ntawm tib neeg lub cev hauv ntau lub xeev. Nws tsis yog qhov nyuaj kom pom tias nyob rau hauv tib cov xwm txheej, qhov nce ntawm av noo (noo noo hauv huab cua) txo cov electrostatic muaj peev xwm U, uas yog, kev pheej hmoo ntawm ESD raug txo, tab sis nws tseem muaj. Yog li, kev tiv thaiv zoo li qub tsis tuaj yeem tso siab, thiab kev ua haujlwm zoo yuav tsum tau tswj hwm.
(3) Ntim yog txuas txuas ntxiv ua ntej cov khoom tawm ntawm lub hoobkas. Qhov zoo ntawm ntim tshuab ntim ncaj qha cuam tshuam seb cov khoom puas ncav cuag tus neeg siv' s tes lossis tsis tau. Kev ntim khoom yuav tsum yog lub hnab los tiv thaiv kev tiv thaiv zoo li qub, uas yog siv rau kev ntim khoom, kev thauj mus los thiab kev cia khoom ntawm lub tshuab thiab muaj qee qhov cuam tshuam noo-pov thawj.
