Yuav ua li cas tshem tawm cov teeb meem hluav taws xob zoo li qub
Qhov hluav taws xob tsis zoo muaj teeb meem rau cov khoom hluav taws xob, tab sis nws yog qhov tseem ceeb tshaj plaws rau kev lag luam hauv tshuab hluav taws xob kom zoo tiv thaiv hluav taws xob.
Ua ntej, qhov kev puas tsuaj ntawm ESD rau lub ntim lub computer yog tsim ntawm cov laug cam, thiab hnub no lub laug cam yog feem ntau ua ntawm MOS cov tshuab, thiab cov Circuit Court yog qhov yooj yim rau electrostatic siab voltage. Electrostatic discharge (ESD) tshwm sim thaum ib tus neeg los yog cov khoom uas muaj hluav taws xob hauv hluav taws xob tau siv cov cuab yeej no. Thaum lub electrostatic siab voltage raug rau MOS Circuit Court, lub thawv ntu nruab nrog oxide yuav tawg thiab rhuav tshem, ua rau qhov khoom siv hluav taws xob yuav raug puas tsuaj lossis ua txhaum ntawm qhov chaw. Ntawm chav kawm, cov khoom siv feem ntau tawm hauv lub tshuab hluav taws xob tsis tag tam sim ntawd, uas yog vim li cas neeg feem coob tsis kam them rau ESD. Qhov tseeb, nyob rau hauv txhua txhua hnub lub neej muaj hluav taws xob, qhov kev xyaum ua pov thawj tias cov tib neeg muaj peev xwm hnov tau hluav taws xob tsawg tshaj li 3.5kV los yog tshaj, thiab hluav taws xob uas muaj peev xwm hnov suab tau siab tshaj 4.5kV, thiab hluav taws xob hluav taws xob nyob rau lub tsho yog ntau dua 5kV.
Ntxiv rau cov lus hais saum toj no-hais ESD ncaj qha rau ua kom ntaus ntawv, ESD kuj ua rau muaj kev cuam tshuam txog cov nyhuv (los yog cov kab mob phem thyristor) hauv MOS Circuit Court. Yog li ntawd, qhov tseem ceeb ntawm MOS tsub kom ua tau zoo heev, thiab cov txiaj ntsim ntawm kev siv logic tsis ua, ua rau muaj kev txheeb ze qhov ntsuas. Thaum MOS Circuit Court yog nyob rau hauv lub xeev xauv, tsuav yog lub hwj huam tsis raug txiav tawm, lub Circuit Court tseem yuav ua rau lub sij hawm ntev, uas yuav raug hlawv tawm hauv Circuit Court los yog ua rau qhov kev ua tau zoo ntawm qhov Circuit Court. Piv txwv li, thaum lub tshuab luam ntawv ntsaws los yog ntsaws thiab lub computer tsis txawv txav (tus nas tsis txav mus, lub tshuab hluav taws xob ceeb toom), thawj kev kho yog kaw tam sim ntawd.
Rau qhov kawg no, cov koom haum thoob ntiaj teb tau tsim cov qauv coj los sib txuas rau cov teeb meem hluav taws xob ua rau ESD ua rau cov hauv qab no:
1. Ua haujlwm ntawm ESD tsis ua hauj lwm Tus neeg uas tau siv lub koos pis tawj nrog lub zog hluav taws xob. Thaum nws kov qhov pom ntawm lub computer xws li keyboard, nas, reset khawm, nws yuav ua rau lub computer tsis ua haujlwm vim ESD: qhov txawv txav xws li lub computer pib, ncua, sib tsoo, thiab lwm yam. Koj yuav tsum pib dua lossis rov qab muab dua ib daig software, tab sis koj yuav tsum tau hloov cov kho vajtse.
2. Kev saib xyuas ntawm ESD tsis ua hauj lwm Tus neeg uas siv lub koos pis tawj tau hluav taws xob, thiab nws nphav tau cov hlau hluav taws xob hauv lub chassis. Piv txwv, kov lub rooj tsav npav thiab daim npav los ntawm txhais tes yuav ua rau ua txhaum cai saum no.
3. Kev Cuam Tshuam Txhaum Cai ESD Tus neeg uas siv lub tshuab computer yog electrostatically charged, thiab ESD uas tshwm sim thaum nws kov lub computer CPU, lub rooj tsav xwm, thiab lwm yam., Yuav ua rau kev puas tsuaj rau cov khoom.
Thib ob, tshem tawm ntawm ESD cov kev ntsuas 1. Cov qauv sib txuas Hnub no lub khoos phis feem ntau muaj cov xaim av, lub xaim av thiab AC thiab cov xaim av uas txuas nrog ob lub lag luam me me tib lub sijhawm, lub xeev av tsis zoo rau cov neeg xav paub ntau ntxiv , Tsuav koj kov cov hlau, koj yuav hnov lub hwj chim (tsuas yog 110V, tam sim no me heev). Lub peev xwm ntawm lub nti rau qhov muaj qhov tsis txaus siab yog qhov tsawg tshaj li ntawm 110V, yog li cov khoom siv computer (xws li lub tshuab computer, lub tshuab luam ntawv, saib, thiab lwm yam) tsis tag nrho, qhov chaw nres nkoj thiab daim card yuav raug puas tsuaj. Niaj hnub no, ntau qhov chaw dav tshav thaiv zoo li peb-xaim, thiab lub qhov hauv av tsis txuas nrog txhua yam. Cov neeg siv yuav tsum tau them nyiaj tshwj xeeb thaum nriav.
2. Chip thiab board carrier packaging manufacturers feem ntau muab qhov tseem ceeb rau ESD. Cov khoom siv khoos phis tawj yuav siv cov hnab yas los tiv thaiv ua ntej tawm hauv Hoobkas. Cov ntaub ntawv ntim khoom uas muaj cov rwb thaiv tsev zoo tuaj yeem yog rau ESD, xws li cov hnab yas npuas, ua npuas yas, thiab lwm yam. Cov ntaub ntawv no tsis haum rau cov khoom ntim khoom siv computer.
3. Cov neeg ua hauj lwm los yog tus saib xyuas cov neeg ua hauj lwm tus kheej txoj kev kho mob Ua ib tus neeg tsav tsheb, nco ntsoov tias HSD muaj kev puas tsuaj, sim tsis txhob kov lub rooj tsav hauv lub computer. Yog tias koj yuav tsum tau kov Circuit Court nrog, koj yuav tsum ntxiv lub nplhaib ntawm koj cov ntiv tes.
4. Chaw ua haujlwm zoo li qub Qhov chaw ua haujlwm yuav tsum siv lub qhov rooj tiv thaiv tsis zoo (Faj seeb: qhov hluav taws xob muaj hluav taws xob yooj yim yog yooj yim los taug kev txhua hom ntaub pua tsev, yog lub qhov dej nyob sab hauv qis tsis txaus, nws yooj yim rau tsim hluav taws xob), thiab qhov zoo humidity yuav tsum yog 40% -60%.
5. Txhawb lub nti ntawm pawg thawj coj los txhim kho kom muaj peev xwm tiv thaiv ESD. Tus ntiv tes muaj tsawg tus ESD tsis kam. Yog hais tias tus nti yog mounted rau ntawm lub rooj tsavxwm, nws muaj ESD tsis kam. Qhov no yog vim li cas, xws li ua kom lub pins ntawm ib qho yooj yim ntawm CMOS nti thiab tom qab ntawd thauj nws.
6. Ntsuas instrumentation thiab cov hlau nplaum hluav taws xob kuj yuav tsum tau muab tso rau hauv. 7. Kev txhim kho kom zoo ntawm cov cuab yeej nws tus kheej Yuav kom tiv thaiv lub computer qhov chaw nres nkoj ntawm ESD kev puas tsuaj, txoj kev zoo tshaj plaws yog los txhim kho qhov khoom zoo ntawm qhov khoom siv.
