Yuav ua li cas xaiv cov khau zoo li qub?
Kev tshawb fawb txog cov khau zoo li qub tau qhia tias theem ntawm tus neeg ua haujlwm lub cev yog nyob ntawm cov ntaub ntawv ntawm ob qho tib si anti-anti-anti-anti-anti-anti-anti-anti-anti-anti-anti-anti-anti-anti-anti-anti-anti-anti-anti-anti-zoo li qub. Yog li ntawd, systemsically ntsuas ntsuas ESD hauv cov khau tiag tiag, los ntawm kev tawm tsam cov khau zoo li qub hnav los ntawm cov neeg ua haujlwm los tiv thaiv cov ntaub ntawv qub thiab cov ntaub ntawv siv tau zoo.
Tam sim no, ib qho teeb meem uas ib txwm muaj nyob hauv cov kev lag luam khau zoo li qub yog tias kev tawm tsam khau zoo li qub tsis tau raws li 100V HBM siv hluav taws xob. Qhov no yog vim tias feem ntau anti-anti-anti-anti-anti-anti-anti-anti-anti-anti-anti-anti-anti-anticent kev lag luam tsis ruaj khov, ua rau cov hluav taws xob uas ua rau lub sijhawm tsis sib xws, ua rau tsis nkag siab ua haujlwm.
Txhawm rau kov yeej qhov teeb meem no thiab txo qhov hluav taws xob ntawm tib neeg lub cev, ib txoj hauv kev yog txhawm rau txhim kho cov hluav taws xob ntawm cov khau, ua rau lawv muaj kev coj ua ntau dua. Txawm li cas los xij, qhov no yuav tsum tau txwv rau qee yam kev tiv thaiv ntau yam kom tau raws li kev nyab xeeb cov kev cai ntawm cov chaw haujlwm muaj feem.
Nws tseem yog ib qho tseem ceeb kom nco ntsoov tias qhov tsis kam los ntawm tib neeg lub cev yuav tsis tsawg tshaj li 1 * 10e ohms, raws li tau hais tias muaj kev phom sij thiab zam kev phom sij thiab zam kev muaj kev phom sij.
Qee tus kws qhia ESD tsis nkag siab tias ntev npaum li qhov kev tawm tsam ntawm lub cev mus rau hauv av yog tsawg dua 3.5 * 108 Ohms yuav tsis pub dhau 100V HBM hauv kev ua haujlwm ESD. Yog tias cov kev tsis nkag siab tsis raug kho, lawv tsim kev pheej hmoo ib puag ncig thaum tuav thiab tiv thaiv cov khoom siv uas pom tau muaj nyob hauv ntau cov khoom lag luam microchip.
Nws yog ib qho tseem ceeb rau cov neeg siv khau es yog nkag siab tias nws yog lub cev voltage, tsis yog lub cev-rau-hauv av tsis kam, uas tuaj yeem ua rau microchips.
Yog li ntawd, qhov zoo tshaj plaws, khau lossis khau txheej yuav tsis tsuas yog khaws lub cev voltage qis dua 100 hauv av uas haum rau-hauv av.
Txawm li cas los xij, cov neeg siv feem ntau tsis paub txog cov kev daws teeb meem yooj yim uas tuaj yeem ua tiav lub cev hluav taws xob tsis muaj kev siv dab teg ntawm caj dab.
Ib qho kev daws teeb meem yooj yim thiab ua tau zoo tshaj plaws ntawm kev ua lag luam yog siv cov tshuaj tua kab mob zoo li qub. Anti-zoo li nkawm khau muaj cov bracket U-puab, tus Tsov tus tw ntawm uas tuaj yeem ua rau muaj kev sib cav sib ceg ntawm cov khau. Muaj ib txoj hlua roj hmab elastic band qhwv ib ncig ntawm sab saud thiab ib leeg ntawm khau. Cov khau tuaj yeem ua qauv ESD lossis tus qauv uas tsis yog tus qauv.
