Yuav siv cov khoom siv li cas nrog lub peev xwm antistatic tsawg


Rau cov siv ntawm cov khoom siv, cov twj tso tawm uas muaj lub siab antistatic muaj peev xwm ib txwm nrov dua li cov khoom siv uas muaj lub siab antistatic. Txawm li cas los xij, nrog kev txhim kho VLSI, kev tsim qauv-down tsim tau coj los ua kom tiav qhov me me, lub teeb yuag, kev siv hluav taws xob tsawg, kev koom ua ke siab, thiab kev ua haujlwm siab, kev ntseeg siab, kev tawm tswv yim tsawg, thiab cov zis siab. Qhov zoo ntawm kev hloov ceev thiab lwm yam. Kev tsim cov tshuab thev naus laus zis xws li qhov khoob ntawm cov hlwv qis thiab cov txheej txheem oxide tau siv rau hauv cov txheej txheem tsim, thiab lub peev xwm antistatic ntawm cov khoom siv tau txais zuj zus.


Lub peev xwm antistatic ntawm lub cuab yeej sib txawv nrog cov qauv tsim thiab tsim ua tiav ntawm lub cuab yeej. Piv txwv li, CMOS, piv nrog PMOS thiab NMOS li, txawm hais tias lub peev xwm antistatic yog nyob rau tib qho kev txiav txim ntawm qhov ntau, CMOS cov khoom siv muaj qhov siab dua me ntsis muaj peev xwm siab dua PMOS thiab NMOS li ntawm ntau pua volts.


Tus neeg siv cov kev thov rau ib lub cuab yeej muaj lub siab antistatic yog, rau qee yam, tsis yog qhov tseeb. Ua ntej, cov cuab yeej nrog lub siab muaj peev xwm muaj qhov ua tau zoo yog cov nyom ntau hauv cov qauv tsim thiab kev tsim khoom, thiab tus nqi yuav siab dua. Thib ob, cov cuab yeej siv uas muaj lub siab antistatic muaj qhov kim thiab tus nqi ntawm tag nrho cov tshuab nce.

Kev pom ntawm qhov xwm txheej saum toj no, nws raug nquahu kom ntxiv qhov hloov hluav taws xob tsis xwm yeem (TVS) rau kev tiv thaiv xob laim, tiv thaiv kev tiv thaiv overvoltage, antistatic thiab tiv thaiv kev cuam tshuam ntawm cov tswv yim / cov lus hais ntawm cov khoom siv rhiab nrog tsis tshua muaj antistatic thaum tsim lub tshuab tag nrho Cov. Muaj peev xwm ua tau zoo tuaj yeem txhim kho qhov antistatic muaj peev xwm ntawm tag nrho lub tshuab. Cov kev hloov pauv hluav taws xob tsis xwm yeem tau siv dav hauv lwm qhov chaw siab xws li kev sib txuas lus, khoos phis tawj, I / O cov chaw nres nkoj, thiab cov teeb liab tawm tswv yim / tiv thaiv.


Transient Voltage Hluav Taws Xob Hluav Taws Xob (TVS) yog qhov kev tiv thaiv kev ua haujlwm siab. Thaum lub tshuab hluav taws xob hloov pauv ntawm cov diode hloov pauv tau hloov lub zog hluav taws xob muaj qhov hloov pauv, nws hloov lub siab ntawm nws ob tus ncej mus rau qhov tsis muaj qhov kawg ntawm qhov ceev ntawm qhov kev txiav txim ntawm 1 x 10-12 s. Kev nqus hluav taws xob tsis muaj zog ntawm ntau txog ob peb kilowatts, qhov hluav taws xob nyob nruab nrab ntawm ob tus ncej yog clamped rau tus nqi ua ntej, tiv thaiv qhov cuam tshuam ntawm cov hluav taws xob hluav taws xob tsis zoo los ntawm cov xov hluav taws xob ntau los ntawm ntau cov kab mob ntsws. Cov cuab yeej muaj qhov zoo ntawm cov lus teb ceev ceev lub sijhawm, lub sijhawm hloov pauv loj, tsis muaj hluav taws xob tam sim no, tswj tau yooj yim ntawm clamping voltage, tsis muaj kev txwv kev puas tsuaj, ntim me me, thiab lwm yam, thiab tau siv dav hauv ntau thaj chaw.
