Kev phom sij ntawm hluav taws xob zoo li qub rau Chips
Cov khoos phis tawj yog tsim los ntawm cov rooj sib tham hauv Circuit Court, feem ntau yog tsim los ntawm MOS technology. Cov circuits no muaj kev nkag siab zoo rau electrostatic paug (ESD). Thaum ib tus neeg lossis cov khoom nqa hluav taws xob zoo li qub kov cov khoom siv no, ESD tshwm sim. Thaum ESD qhov hluav taws xob siab no cuam tshuam rau MOS Circuit Court, cov yeeb yaj kiab oxide sab hauv tau tawg thiab puas, ua rau muaj kev puas tsuaj tam sim lossis ua haujlwm tsis zoo ntawm cov khoom. Txawm li cas los xij, cov khoom siv uas raug rau ESD feem ntau tsis poob tam sim ntawd, yog vim li cas tib neeg feem ntau tsis nyiam ESD ntau. Qhov tseeb, hluav taws xob zoo li qub yog muaj nyob rau hauv lub neej txhua hnub. Kev paub qhia tau hais tias cov hluav taws xob zoo li qub uas tib neeg tuaj yeem xav tau yog tsawg kawg 3.5kV, qhov hluav taws xob zoo li qub uas tuaj yeem hnov tsawg kawg yog 4.5kV, thiab hluav taws xob zoo li qub uas ua rau lub teeb nyem ntawm lub tsho tshaj tawm yog tsawg kawg 5kV.
Dhau li ntawm kev puas tsuaj ncaj qha, hluav taws xob zoo li qub tuaj yeem ua rau lub latch - nce cov nyhuv (los yog cov kab mob parasitic silicon tswj cov nyhuv rectifier) hauv MOS Circuit Court. Qhov no ua rau muaj kev nce ntxiv hauv cov tam sim no hauv MOS, ua rau muaj kev ua haujlwm tsis zoo hauv lub logic thiab yog li ntawd -hu ua latch- nce cov nyhuv. Thaum MOS Circuit Court raug kaw, nws yuav nyob twj ywm tsis muaj qhov kawg yog tias lub hwj chim tsis raug txiav tawm. Nyob rau tib lub sijhawm, qhov no tuaj yeem hlawv tawm hauv Circuit Court lossis degrade nws qhov kev ua tau zoo. Piv txwv li, yog tias lub khoos phis tawj ua haujlwm tsis zoo (nias nres ua haujlwm, lub tswb lub tshuab luam ntawv) vim yog kub- ntsaws lub tshuab luam ntawv txuas, thawj qhov kev ntsuas yuav tsum kaw lub computer tam sim ntawd.
Yog li, cov koom haum thoob ntiaj teb tau tsim tshwj xeeb tsim cov qauv sib xws, faib ESD- cuam tshuam hluav taws xob rau hauv cov pawg hauv qab no:
1. Kev Ua Haujlwm ESD Faults
Thaum tus neeg ua haujlwm lub khoos phis tawj nqa hluav taws xob zoo li qub thiab kov qhov chaw sab nraud ntawm lub khoos phis tawj xws li cov keyboard, nas, lossis khawm rov pib dua, ESD yuav ua rau lub khoos phis tawj nram qab no: lub khoos phis tawj rov pib dua, nres, lossis poob. Cov teeb meem me me yuav xav tau rov pib dua lossis rov nruab software, thaum cov teeb meem loj yuav xav tau kev hloov kho kho vajtse.
2. Kev Kho ESD Faults
Thaum ib tus neeg ua haujlwm hauv lub computer nqa hluav taws xob zoo li qub thiab kov cov khoom siv hlau hauv lub computer, xws li cov rooj sib tham sab hauv lossis cov ntawv teev lus, cov teeb meem saum toj no yuav tshwm sim.
3. Kho ESD Faults
Thaum ib tus neeg ua haujlwm hauv lub computer nqa hluav taws xob zoo li qub thiab kov CPU, Circuit Court boards, lossis lwm yam khoom, ESD tuaj yeem ua rau cov khoom no puas tsuaj.
Peb pom zoo kom koj siv lub tshuab hluav taws xob tso tawm hluav taws xob zoo li no.
