Dab tsi yog qhov tsis zoo ntawm hluav taws xob zoo li qub rau cov khoom siv sib kis?
Cov phom sij ntawm cov hluav taws xob zoo li qub mus rau cov khoom siv kho qhov muag
Cov hluav taws xob tso hluav taws xob (Electrostaticdischarge. ESD) muaj kev puas tsuaj loj rau cov khoom siv hluav taws xob cov khoom siv.Qhov kev ua haujlwm tseem ceeb yog electrostatic tawm tuaj yeem ua kev puas tsuaj rau kev sib txuam, cov khoom siv piezoelectric, zaj duab xis resistors, zaj duab xis nyias, thiab tuab zaj duab xis khoom hauv lub xeev hauv cov khoom siv hluav taws xob, yog li nce kev saib xyuas tus nqi ntawm cov khoom siv hluav taws xob thiab lub sijhawm ncua sijhawm tu, thiaj li txo cov kev siv ntawm cov khoom siv hluav taws xob.
Electrostatic kev puas tsuaj rau cov khoom siv kho qhov muag muaj plaub yam ntxwv:
1) Kev sib dhos: feem ntau, electrostatic kev puas tsuaj rau cov khoom siv kho qhov muag, tib neeg lub cev tsis tuaj yeem pom, ntawm chav kawm, tshwj tsis yog electrostatic tawm.Because tib neeg lub cev tau paub txog qhov voltage ntawm electrostatic paug yog 2-3kv, electrostatic paug ntawm tib neeg lub cev yuav tsis muaj qhov kev xav ntawm hluav taws xob hluav taws xob, yog li hluav taws xob zoo li qub yog zais.
2) Latent: kev tsim thev naus laus zis ntawm cov khoom siv kho qhov muag kis tau ntau dua thiab ntau dua, kev puas tsuaj ntawm cov khoom sib xyaw los ntawm hluav taws xob zoo li qub mus rau cov khoom siv kho qhov muag feem ntau tsuas yog ua rau kev ua haujlwm ntawm cov khoom siv kho qhov muag kom muaj qee yam kev hloov pauv, tab sis nws tsis poob kua hlo li. Feem ntau, nws yog qhov nyuaj heev kom pom thaum lub sijhawm saib xyuas ntawm cov khoom siv kho qhov muag.Txawm li cas los xij, ntau qhov kev kho mob electrostatic, tshwj xeeb tshaj yog ntau qhov paug tawm, tuaj yeem ua rau raug mob sab hauv ntawm cov khoom siv kho qhov muag thiab cuam tshuam rau kev ua haujlwm ntawm cov khoom siv kho qhov muag.
3) Randomness: los ntawm kev tsim cov khoom tivthaiv rau cov khoom siv kho qhov muag, kom txog thaum cov khoom puas, tag nrho cov txheej txheem yuav raug teeb meem los ntawm hluav taws xob zoo li qub.Thaum txoj kev xav no, kev puas tsuaj ntawm electrostatic mus rau cov khoom siv kho qhov muag kis tau yog random.
4) Cov khoom sib txawv: kev puas tsuaj ntawm cov khoom siv hluav taws xob zoo li qub cuam tshuam rau kev ua haujlwm ntawm cov khoom siv, vim tias cov khoom siv hluav taws xob cov khoom sib txawv yog cov yam ntxwv me heev, yog li cov khoom siv niaj zaus kev saib xyuas yog qhov nyuaj, thiab xav tau kev saib xyuas tas li muaj qib siab dua. nyuaj cais qhov sib txawv ntawm lwm qhov ua rau kev puas tsuaj, ua rau tib neeg ua txhaum lub txim txhaum qub rau lwm qhov kev ua txhaum.Thaum tib lub sijhawm, cov neeg saib xyuas txhua hnub yog ib qho yooj yim xav tias qhov tsis ua hauj lwm ntawm ib pawg tswj hwm yog tshwm sim los ntawm lwm yam, uas hais txog cov laj thawj tiag tiag qhov tsis ua hauj lwm ntawm Cheebtsam.Yog li ntawd, qhov kev tsom xam ntawm kev puas tsuaj ntawm lub rooj tsav xwm ib leeg hauv lub cuab yeej hluav taws xob hauv cov khoom siv sib kis tau yog qhov nyuaj.
SFP module muaj ntau cov khoom muaj tseeb ntsig txog qhov ntsuas thiab cov khoom siv Circuit Court. Hauv txhua txhua hnub, peb yuav tsum ua cov haujlwm ntawm electrostatic tiv thaiv kev ua haujlwm, txwv tsis pub nws yooj yim heev rau kev puas tsuaj rau qhov kho qhov muag.
ESD kev tiv thaiv yuav tsum tau muab khaws cia rau hauv siab
1） ESD tiv thaiv yuav tsum tau ua (xws li: hnav cov hnab looj tes tiv thaiv zoo li qub thiab tiv thaiv zoo li qub dab teg tuaj yeem tiv thaiv kev puas tsuaj electrostatic), sim hu rau lub ntsej muag optical plhaub, tsis txhob kov lub ntsej muag optical PIN PIN taw;
2） Ua kom qhov av noo ntawm qhov chaw ib puag ncig uas qhov ntsuas hluav taws xob tau siv ntawm thaj tsam li 30 txog 75% RH;
3） Nws yog nruj me ntsis txwv tsis pub nqa tawm kub txuas thiab tshem cov haujlwm ntawm cov khoom siv tsis kub thiab tsis zoo.
HTF Cia siab tsab xov xwm no kom txhua tus nkag siab txog qhov cuam tshuam ntawm hluav taws xob zoo li qub rau cov khoom siv kho qhov muag ntawm kev sib faib saum toj no, thiab ua txoj haujlwm zoo ntawm kev ua haujlwm tiv thaiv kev ua haujlwm thaum lub sijhawm ua haujlwm kom cov khoom siv thiab cov khoom tuaj yeem lav lawv cov kev pabcuam lub neej zoo thiab ntev dua.
