Nyob rau hauv lub ntiaj teb no ntawm semiconductor fabrication, lub txim me tshaj plaws yuav ua rau muaj kev puas tsuaj loj tshaj plaws. Peb tsis tham txog hluav taws kub -peb tab tom tham txog Electrostatic Discharge (ESD). Thaum koj tab tom soj ntsuam cov khoom ntsuas hauv nanometers, tus nqi zoo li qub uas tib neeg tsis tuaj yeem hnov yog txaus rau yaj sab hauv circuitry, ua rau "latent defects" uas ua tsis tau tsuas yog tom qab cov khoom mus txog tus neeg siv khoom.
Txhawm rau tswj hwm lub ntiaj teb - cov txiaj ntsig hauv chav kawm, koj qhov kev qhuab qhia huv huv yuav tsum yog airtight. Sawv ntsug ntawm cov kab pem hauv ntej ntawm lub Hoobkas hauv pem teb, peb paub tias qhov sib xws yog peb qhov kev tiv thaiv zoo tshaj plaws. Ntawm no yog peb mus- mus rau daim ntawv teev npe rau kev tiv thaiv cov neeg ua haujlwm, tsom mus rau peb tus ncej ntawm kev hnav txhua hnub: khaub ncaws, khaub ncaws hnav, thiab kev tiv thaiv tes.
1. Cov ris tsho tiv thaiv: Cov ntaub thaiv npog
Tib neeg lub cev yog ib tug taug kev capacitor. Yog tias tsis muaj av zoo, txhua qhov kev txav mus los tsim kev sib txhuam thiab zoo li qub tsim- nce. Cov tsho loj hauv chav kuaj yuav tsis txiav nws nyob rau hauv siab -stakes ib puag ncig.
Material Integrity:Xyuas kom meej tias tag nrho cov smocks yog ua los ntawm cov khoom zoo li qub -cov ntaub so ntswg (feem ntau yog polyester- cov kab sib chaws carbon).
Txoj Cai "Sleeve":Lub tes tsho yuav tsum ntev txaus los npog tag nrho cov khaub ncaws ntawm tus kheej. Ib lub tsho wool stray cuff peeking tawm yog ib qho kev tshwm sim ESD tos kom tshwm sim.
Hluav taws xob txuas ntxiv:Tsis tu ncua kuaj koj cov khaub ncaws tom qab ntxhua khaub ncaws. Cov fibers conductive tuaj yeem tawg dhau lub sijhawm, txo qhov ua tau zoo ntawm kojSemiconductor ESDkev tiv thaiv.
2. Cleanroom Headwear: Ntau tshaj li cov plaub hau ntim
Thaum lub kaus mom thiab lub kaus mom feem ntau pom tias yog kev tiv thaiv kev sib kis rau cov khoom (daim tawv nqaij flakes thiab plaub hau), lawv ua lub luag haujlwm tseem ceeb hauv kev cog qoob loo.
Pob ntseg-rau- Pob ntseg:Lub hood yuav tsum tau muab tso rau hauv lub smock kom paub meej tias txoj kev tsis tu ncua.
Conductive strips:High -spec hoods feem ntau muaj cov kab hluav taws xob uas kov cov tawv nqaij lossis txuas rau lub tsho kom ntseeg tau tias lub taub hau tsis dhau los ua lub tshuab hluav taws xob cais tawm.
Haum thiab foob:Xyuas kom lub ntsej muag qhib yog snug. Cov khaub ncaws xoob tuaj yeem ua rau muaj kev sib txhuam ntawm tus kheej cov plaub hau, tsim kom muaj nqi ntawm ib sab ntawm cov khoom siv rhiab.
3. Hnab looj tes thiab ntiv tes cots: Qhov taw tes ntawm kev sib cuag
Koj txhais tes yog qhov feem ntau ntawm kev sib cuag nrog wafer lossis PCB. Qhov no yog qhov "kev tso tawm" hauv ESD feem ntau tshwm sim.
Surface Resistivity:Siv cov hnab looj tes nitrile lossis vinyl tshwj xeeb rau ESD ib puag ncig. Lawv yuav tsum muaj qhov kev tiv thaiv saum npoo feem ntau ntawm $ 10^5$ thiab $ 10^{11}$ ohms ib square.
Hmoov-Dawb nkaus xwb:Tsis txhob siv cov hnab looj tes hmoov, vim tias cov khoom tuaj yeem cuam tshuam rau ob qho tib si ntawm lub cev huv huv thiab cov khoom siv hluav taws xob.
Snug Fit:Ib lub hnab looj tes xoob tsim kom muaj qhov sib txawv ntawm huab cua uas tuaj yeem ua raws li cov khoom siv insulator, tiv thaiv cov nqi ntws mus rau hauv av los ntawm lub dab teg.
Nyem "Ua ntej koj nkag mus" daim ntawv teev npe
Ua ntej tus neeg teb xov tooj nce mus rau hauv pem teb, lawv yuav tsum dhau los ntawm qhov chaw pov thawj. Yog tias koj tab tom tswj kev hloov pauv, xyuas kom meej tias peb cov kauj ruam no tsis yog - sib tham tau:
- Visual Check:Tsis muaj cov hniav nyiaj hniav kub tus kheej lossis tsis yog -ESD- cov khaubncaws sab nraud povtseg.
- Dab teg Strap & Khaub Ncaws Test:Txhua tus neeg ua haujlwm yuav tsum tau ntsaws rau hauv thiab dhau qhov kev xeem tiv thaiv.
- Ionization xyuas:Xyuas kom cov huab cua ionizers ntawm cov chaw ua haujlwm ua haujlwm kom tsis txhob muaj cov nqi uas cov khaub ncaws tiv thaiv tsis tau.
ESD kev nyab xeeb yog kab lis kev cai, tsis yog ib qho kev cai. Thaum koj pab neeg nkag siabvim li cascarbon-grid smock yog qhov tsim nyog, kev ua raws cai txav ntawm "yuav tsum tau" mus rau "automatic."
Kev tswj kom zoo li qub - ib puag ncig nyab xeeb yog marathon, tsis yog kev sib tw. Los ntawm kev tsom mus rau cov hauv paus ntsiab lus ntawm "Lub tsho tiv no, Cap, thiab Hnab looj tes," koj tiv thaiv koj cov txiaj ntsig, koj lub koob npe nrov, thiab cov thev naus laus zis uas ua rau peb lub ntiaj teb.
Puas yog koj lub tsev kho mob tam sim no hloov kho nws cov qauv PPE, lossis koj puas tab tom nrhiav los daws qhov teeb meem tshwj xeeb uas cuam tshuam txog qhov zoo li qub?
