Ua mob ntawm cov hluav taws xob hluav taws xob ntawm cov hluav taws xob hluav taws xob thiab cov kab IC
1. Electrostatic voltage rau semiconductor thiab IC cov kab
1 hnav ntaub nylon khaub ncaws, nkawm khau yas hloov maj mam tsiv rau hauv pem teb huv si, tib neeg lub cev yuav coj 7KV-8KV voltage
2 Thaum cov kab ua siv lead ua los ntawm iav fiber ntau slides hla lub rooj polypropylene, nws yog ib qho yooj yim los ua kom muaj 10KV zoo li qub hluav taws xob.
3 wafer sib dhos: wafer 5KV, wafer loading box 35KV, khaub ncaws 10KV, duab 10KV, npog npog 8KV, quartz Crystal 1.5KV, wafer tais 6KV
4 Lithium chav tsev 500V-1500V pem teb, 500V-1500V, nplov yas phab ntsa yog li 700V, yas qab nthab 0-1000V, phaj ntawm lub qhov cub cua, rov qab Xem cua 500V-1000V, hlau rooj tawv tawv rooj zaum qhov rooj 500V-3000V
2. Muaj cov khoom hluav taws xob hluav taws xob nyob ntawm semiconductor thiab IC cov kab ntau lawm
1 Hnyuv ntawm electrostatic Coulomb quab yuam: Plav thiab av av adsorbed los ntawm electrostatic Coulomb quab yuam tuaj yeem coj cov khoom, uas yuav ua rau kom ntub los sis luv luv, uas yuav ua rau muaj kev cuam tshuam thiab txo cov qoob loo. Yog hais tias qhov loj me me ntawm cov hmoov av yog> 100 μm, qhov dav ntawm txhuas hlau yog li 100 μm, thiab cov thickness ntawm zaj duab xis yog tsawg dua 50 μm, qhov khoom yuav raug khawb. Qhov no tshwm sim nyob rau hauv cov txheej txheem kev txhim kho corrosion, photolithography, chaw vuam thiab ntim.
2 Txoj kev puas tsuaj los ntawm kev tso tawm ntawm electrostatic: Yog tias muaj ntau txhiab tus vab ntau cov khoom uas muaj siab, qhov ua pa hauv lub cev los yog cov pa tawm, thaum muaj kab mob siab heev tam sim no ntws mus rau hauv lub ntiaj teb, lub siab zoo li tam sim no lub siab yog tsim ntawm 20A. , ua rau muaj kev cuam tshuam, electrostatic discharge (ESD) kuj muaj lus los ntawm electromagnetic nthwv dej emission, uas yuav ua rau muaj ntau yam kev phom sij.
A, MOSIC thiab lwm yam khoom siv hluav taws xob yuav raug rho tawm hauv electrostatically (ESD) los yog ib nrab kev rhuav tshem. Lub rooj vag ntawm MOS field effect transistor tawm ntawm oxide zaj duab xis, thiab ib zaj duab xis oxide yog ntxim lub nruab nrab ntawm lub qhov rooj thiab lub substrate. Thaum lub qhov nruab nrab ntawm lub qhov rooj thiab lub substrate tshaj ib qho nqi, oxide zaj duab xis tawg lawm, yog MOSIC, Ces tag nrho cov scrapped. Thaum cov pa roj carbon monoxide applied rau UB = 50-100V, oxide zaj duab xis yuav tawg vim qhov rooj loj yog qhov tsawg (tsawg dua ib txhia picofarads), thiab cov kev tawm tswv yim ua haujlwm siab heev (txog 1014Ω lossis tshaj saud). Ib qho nqi me me yuav ua rau muaj kev kub nyhiab, thiab tus nqi yuav nyuaj rau tog. Tsuav nws siab tshaj 50V (tsis muaj kev tiv thaiv), nws yuav hlawv tawm. Yog li, ntev li ntev tau tus neeg tsom cov kab sib chaws, qhov tivthaiv yuav tawg, vim nws yog ib qho rau cov neeg yuav tsum tau them ntau tshaj 50V. .
Peb tuaj yeem nkag siab txog qhov kev sib luag ntawm cov kev kho hluav taws xob rau hluav taws xob. Qhov txawv ntawm ntau lub chips yog hais tias lawv muaj peev xwm tiv ntau yam zoo li qub voltage qhov tseem ceeb. Nyob rau hauv cov tswv yim, ib voltage zoo li qub ntawm yuav luag 20V ncaj qha hu cov cuab yeej los txov lossis thuam kev ua tau zoo.
Electrostatic discharge ua puas tsuaj rau kev ua kom tag nrho cov ntawv luam tawm ntawm circuit board, ua rau nyiaj txiag poob;
Lub suab ntawm electrostatic tso tawm ua rau qhov ua tsis zoo los yog ua tsis zoo ntawm cov khoom siv thiab qhov kev tawm ntawm lub cev. Qhov tshwm sim ntawm qhov ntsuas plas kab tawm, ntxiv nrog rau ua lub plhaub loj ntawm lub sijhawm tam sim no, thiab ua rau muaj lub suab nrov nrov thoob ob peb lub hauv siab lossis ntau pua pua ntawm hertz. Nyob rau xyoo tas los no, kev tshawb fawb txog kev siv lub computer ua los ntawm lub teeb tsa electrostatic tawm suab tau zoo heev.
Thaum cov electromagnetic tsis generated thaum lub caij tawm nkag nkag mus rau lub receiver, lub suab nrov nrov ntawd ua, uas cuam tshuam nrog lub teeb liab los txo cov kev qhia los yog ua rau cov ntaub ntawv yuam kev.
3, qhov txaus ntshai ntawm electrostatic induction
Cov khoom tsim tawm los ntawm hluav taws xob muaj hluav taws xob sib npaug kiag li rau lub cev, thiab muaj cov electrostatic phenomena thiab paug phenomena. Yog hais tias qhov tsis kam ntawm cov khoom nti yog ib tus neeg xyuas me me, cov pa tawm yuav tshwm sim thiab ua rau raug mob.
A. Nyob rau hauv qhov kev cob qhia ntawm kev lag luam ntau lawm.
Nyob hauv cheeb tsam ntawm cov khoom siv hluav taws xob thiab cov kab, thaum cov neeg ua haujlwm voj, MOS cov khoom lossis MOSSI, vim electrostatic induction, nws yog ib qho yooj yim uas yuav ua rau paug hluav taws xob tawm ntawm lub cev tib neeg lub cev, qhov ua rau lub tshuab puas tsuaj.
B. Cua txias airflow (ion flow) thauj los ntawm qhov kav dej yog sib npaug rau thaum tib neeg lub cev hnav. Thaum cov tib neeg lub cev nyob rau hauv kev sib txuas nrog cov khoom nti, cov electrostatic tso tawm yuav zom cov khoom puas.
4. Muaj kev puaj phom rau khoom hluav taws xob rau cov khoom siv hluav taws xob
Txhua yam ntawm kev siv lub tshuab yuav raug kev txom nyem los ntawm electrostatic kev puas tsuaj. Lub ntsiab tseem ceeb muaj xws li: kev yuav khoom thiab kev thauj mus los ntawm cov khoom siv; kev soj ntsuam thiab kev lees txais ntawm cov khoom siv mus rau hauv lub hoobkas; khaws cia thiab khaws cov khoom siv; ntaus ntawv thiab tshuab cawm siav; khoom sib dhos thiab tshuaj ntsuam xyuas; khoom ntim thiab tub.
Ntxiv nrog rau kev puas tsuaj ntawm hluav taws xob thaum lub sij hawm tsim hluav taws xob thiab cov khoom siv hluav taws xob, nws tseem raug rau hluav taws xob thaum lub sijhawm siv qhov khoom. Hauv kev xaus, qhov kev puas tsuaj los ntawm hluav taws xob muaj zog yog qhov txaus los ua rau cov khoom siv hluav taws xob thiab cov twj siv hluav taws xob tawm hauv kev tawm, thiab kev puas tsuaj rau cov khoom siv hluav taws xob thiab cov khoom siv tsis raug.
