Thaum cov khoom siv hluav taws xob hloov zuj zus mus rau qhov me me thiab kev ua haujlwm siab, cov varistors tseem yog ib qho tseem ceeb rau kev tiv thaiv overvoltage. Txawm hais tias nyob rau hauv cov khoom siv ntse, cov khoom siv hluav taws xob hauv tsheb, lossis kev tswj hwm kev lag luam thiab cov tshuab fais fab, cov varistors ua haujlwm ua cov neeg tiv thaiv pem hauv ntej tiv thaiv kev nce siab ntawm cov hluav taws xob. Txhawm rau kom ntseeg tau tias lawv teb sai dua, kav ntev dua, thiab ua haujlwm tau zoo, kev ua tau zoo tsis yog nyob ntawm lub hauv paus ceramic xwb tab sis kuj - qhov tseem ceeb - ntawm qhov zoo ntawm kev kho qhov chaw. Tshwj xeeb, kev txheej txheem nqus tsev tau dhau los ua qhov tseem ceeb ntawm kev tsim cov varistor siab ntseeg tau.
1. Tus Varistor Ua Dab Tsi Tiag?
Hauv cov lus yooj yim, varistor yog ib qho resistor uas nyob ntawm qhov voltage. Nws qhov kev tiv thaiv poob qis thaum qhov voltage siv ntau tshaj qhov txwv, yog li ntawd nws thiaj li hloov thiab tshem tawm lub zog surge los tiv thaiv cov circuits downstream. Qhov kev coj tus kheej no ua rau cov varistors zoo tagnrho rau kev tiv thaiv surge, kev tiv thaiv xob laim, thiab kev tswj hwm lub zog voltage ib ntus.
Ua tsaug rau lawv lub sijhawm teb sai, qhov loj me me, thiab tus nqi qis, cov varistors siv dav hauv cov khoom siv sib txuas lus, cov khoom siv hluav taws xob rau cov neeg siv khoom, cov ECU tsheb, thiab cov tshuab hluav taws xob rov ua dua tshiab.
2. Vim li cas kev kho qhov chaw thiaj li tseem ceeb?
Txawm hais tias qhov kev ua tau zoo ntawm varistor yog los ntawm cov khoom siv ceramic zinc oxide, kev ntseeg siab mus sij hawm ntev feem ntau nyob ntawm qhov zoo ntawm nws cov txheej electrode. Hauv kev siv tiag tiag, varistors ntsib cov hluav taws xob rov qab ntau zaus thiab cov chaw hluav taws xob hnyav. Cov zaj duab xis electrode yuav tsum tsis yog tsuas yog ua kom pom kev coj ua zoo heev tab sis kuj tseem muaj kev nplaum zoo, kev ruaj khov thermal, kev tiv thaiv corrosion, thiab kev sib raug zoo tshaj plaws nrog cov khoom siv ceramic.
Hauv lwm lo lus, txawm tias cov khoom siv ceramic zoo tshaj plaws tuaj yeem ua haujlwm tsis zoo yog tias txheej metallization ntawm qhov chaw tsis ua haujlwm. Yog li ntawd, kev tso electrode thiab kev kho qhov chaw tau dhau los ua qhov tseem ceeb hauv kev tsim cov varistor tiam tom ntej.
3. Cov Tshuab Hluav Taws Xob Ib Txwm Muaj Thiab Lawv Cov Kev Txwv
Tam sim no, kev tsim cov electrode varistor feem ntau vam khom kev siv cov nyiaj nplaum sintering, electroplating, thiab screen printing. Txawm li cas los xij, cov txheej txheem ib txwm muaj no ntsib teeb meem loj hlob:
Kev nplaum tsis sib xws: Ntawm cov khoom siv ceramic inert, yuav tev tawv, tawg, lossis tawg.
Kev tsis sib xws ntawm zaj duab xis: Cuam tshuam rau kev sib xws ntawm hluav taws xob thiab txwv tag nrho cov txiaj ntsig.
Kev txhawj xeeb txog ib puag ncig: Electroplating muaj cov hlau hnyav thiab cov tshuaj pov tseg, ua rau kev ua raws li cov qauv ib puag ncig nyuaj.
Kev nthuav dav tsawg: Nyuaj rau ua kom tau raws li qhov xav tau ntawm cov khoom me me thiab cov duab zoo nkauj.
Cov kev txwv no tab tom tsav tsheb rau kev lag luam mus rau qhov tseeb, huv si, thiab cov thev naus laus zis electrode uas tuaj yeem nthuav dav.
4. Txheej Tshuab Nqus Tsev: Ib Txoj Hauv Kev Tshiab Rau Kev Tsim Khoom Varistor
Txhawm rau daws cov teeb meem no, magnetron sputtering - ib hom thev naus laus zis nqus tsev - tau tshwm sim los ua ib txoj hauv kev nyiam rau kev tso electrode rau ntawm varistors.
Nyob rau hauv lub tshuab nqus tsev siab, cov ions muaj zog siab yuav tua lub hom phiaj hlau, ua rau cov atoms raug ntiab tawm thiab tso rau ntawm lub substrate. Cov txheej txheem no ua rau muaj ib txheej zaj duab xis ntom, sib npaug, thiab lo rau ntau qhov zoo tseem ceeb:
Muaj zog nplaum thiab compact qauv, ua kom ruaj khov nyob rau hauv cov xwm txheej rov ua dua.
Kev sib npaug ntawm cov zaj duab xis tuab thiab cov txheej txheem rov ua dua, zoo tagnrho rau kev tsim khoom ntau thiab sib xws.
Cov txheej txheem qhuav thiab huv si, tsis muaj cov tshuaj lom neeg, ua raws li RoHS thiab REACH cov lus qhia.
Kev sib raug zoo nrog cov duab nyuaj, tsim rau cov khoom siv hluav taws xob hom nti thiab cov khoom siv hluav taws xob tsis sib xws.
Niaj hnub no, txheej txheej nqus tsev tau raug siv dav hauv kev tsim cov varistors siab heev, MLCCs, cov resistors nyias-zaj duab xis, thiab lwm yam khoom siv hluav taws xob meej.
