Ceramic metallization yog txheej txheem tseem ceeb hauv kev tshawb fawb thiab engineering, qhov chaw ceramics, paub txog lawv cov hluav taws xob zoo heev thiab thermal stability, yog coated nrog hlau txheej los txhim kho lawv cov conductivity thiab ua kom muaj kev koom ua ke rau hauv hluav taws xob thiab hluav taws xob.
Kev kho saum npoo
Cov txheej txheem ceramic metallization feem ntau muaj ob peb kauj ruam tseem ceeb. Txhawm rau tshem tawm cov impurities thiab tsim kom muaj qhov sib txuas tsim nyog, ceramic substrate yuav tsum tau ua ntej ntxuav thiab kho qhov chaw. Cov kauj ruam no yog qhov tseem ceeb rau kev ua kom zoo adhesion ntawm ceramic thiab hlau txheej. Cov ceramics feem ntau siv hauv cov txheej txheem no suav nrog alumina (Al2O3), zirconia (ZrO2), thiab silicon nitride (Si3N4) vim lawv cov khoom tsim nyog.
Deposition ntawm Metallic Txheej
Tom qab kev npaj substrate, ib txheej nyias nyias yog muab tso rau ntawm qhov chaw ceramic. Ntau yam kev tso tawm tuaj yeem ua haujlwm, suav nrog lub cev vapor deposition (PVD) thiab tshuaj vapor deposition (CVD). PVD txoj kev, xws li sputtering lossis evaporation, koom nrog kev hloov lub cev ntawm cov hlau atoms los ntawm cov khoom siv mus rau qhov chaw ceramic nyob rau hauv lub tshuab nqus tsev. CVD, ntawm qhov tod tes, tso siab rau cov tshuaj tiv thaiv los tsim cov txheej hlau ntawm cov substrate.
Qhov kev xaiv ntawm cov hlau rau deposition yog nyob ntawm daim ntawv thov tshwj xeeb thiab cov khoom uas xav tau. Cov hlau uas siv hauv ceramic metallization muaj xws li kub, nyiaj, tooj liab, thiab txhuas. Kub yog nyiam rau nws zoo heev conductivity thiab tsis kam mus corrosion, ua rau nws haum rau high-reliability daim ntaub ntawv. Silver muaj cov conductivity siab tab sis tej zaum yuav ua rau tarnishing lub sij hawm. Tooj liab yog tus nqi-zoo tab sis tej zaum yuav xav tau cov txheej thaiv kev tiv thaiv kom tsis txhob ya mus rau hauv cov ceramic. Aluminium feem ntau yog siv rau nws tus nqi pheej yig thiab kev sib raug zoo nrog silicon-based ceramics.
Qauv
Thaum cov txheej txheej hlau tau tso, tus qauv yog txhais siv photolithography lossis lwm yam qauv qauv. Qhov no suav nrog kev siv cov khoom siv photoresist rau cov hlau-coated ceramic, nthuav tawm nws los ntawm lub ntsej muag, thiab tom qab ntawd tsim cov qauv. Cov hlau raug raug tom qab etched tam sim ntawd, tawm hauv qhov xav tau metallized qauv ntawm cov ceramic nto.
Tom qab ua tiav
Cov kauj ruam kawg suav nrog kev ua tiav tom qab kom ntseeg tau tias muaj kev ntseeg siab thiab ua haujlwm ntev ntawm cov hlau ua ceramic. Qhov no yuav suav nrog kev ua kom zoo dua qub, kev siv cov txheej tiv thaiv kom tsis txhob oxidation, thiab kev kho ntxiv kom tau raws li cov kev xav tau tshwj xeeb.
Ceramic metallization yog ib qho tseem ceeb ntawm kev ua cov khoom siv hluav taws xob high-tech vim nws cia cov ntaub ntawv ceramic siv rau hauv circuits thiab cov tshuab uas xav tau hluav taws xob zoo. Cov txheej txheem no txuas ntxiv txhim kho nrog kev tshawb fawb tsis tu ncua tsom rau kev txhim kho adhesion, conductivity, thiab tag nrho cov kev ua tau zoo, pab txhawb rau kev nce qib ntawm hluav taws xob thiab hluav taws xob technologies.
