Hauv kev tsim khoom siv hluav taws xob niaj hnub no thiab cov cuab yeej siv siab- kawg, kev sib xyaw ntawm ceramics thiab hlau tau dhau los ua cov thev naus laus zis tseem ceeb. Kev lig kev cai, ceramics, raws li ib txwm inorganic non-cov ntaub ntawv hlau, muaj cov rwb thaiv tsev siab, siab kub tsis kam, thiab kev ruaj ntseg tshuaj zoo heev, thaum hlau zoo tshaj plaws hauv conductivity, ductility, thiab mechanical zog. Ob hom ntaub ntawv no muaj qhov sib txawv tseem ceeb hauv kev ua tau zoo, tab sis nws yog qhov tseeb qhov sib txawv uas ua kom muaj kev sib xyaw ua ke ua tau zoo, ua rau muaj kev siv thev naus laus zis tseem ceeb ntawm ceramic metallization. Cov txheej txheem no ua rau lub ntsej muag ntawm cov ceramics los ua cov khoom siv hluav taws xob, ua rau lawv muaj peev xwm txuas nrog cov hlau, yog li tso cai rau kev siv dav hauv cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob muaj kev ntseeg siab.
Nrog rau kev txhim kho txuas ntxiv ntawm cov cuab yeej siv hluav taws xob, tshwj xeeb tshaj yog nyob rau hauv 5G kev sib txuas lus, siab - lub zog semiconductors, thiab lub zog tshiab, cov kev xav tau ntawm kev ntim khoom yog nce ntxiv. High- zaus, siab- zog- cov khoom siv ntom ntom ua kom muaj cua sov ntau thaum lub sijhawm ua haujlwm, muab cov qauv siab dua ntawm cov thermal conductivity, thermal expansion txuam, thiab kev ruaj ntseg ntawm cov khoom siv Precision Metallized Alumina Ceramic Cheebtsam. Cov ntaub ntawv ceramic, tshwj xeeb tshaj yog alumina- cov ntaub ntawv raws li, yog cov khoom ntim zoo tshaj plaws vim lawv cov thermal conductivity zoo, hluav taws xob rwb thaiv tsev, thiab thermal expansion coefficient ze ntawm cov khoom siv semiconductor. Tom qab ua tiav los ntawm Metallized Ceramics, ceramics tsis tsuas yog muaj rwb thaiv tsev thiab cua sov ua haujlwm tab sis kuj ua kom muaj kev sib txuas hluav taws xob txhim khu kev qha, dhau los ua tus choj tseem ceeb txuas nrog cov chips sab hauv thiab sab nraud.
Nyob rau hauv kev siv tswv yim, metallized ceramic Cheebtsam feem ntau yuav tsum tau tsim ib tug hlau txheej ntawm cov ceramic nto uas yog ruaj khov rau lub substrate. Cov txheej hlau no tsis yog tsuas yog yuav tsum muaj cov khoom siv hluav taws xob zoo xwb tab sis kuj yuav tsum nyob ruaj khov thaum cov txheej txheem vuam txuas ntxiv, tiv thaiv delamination lossis tsis ua haujlwm. Yog li ntawd, lub hauv paus ntawm metallized ceramics nyob rau hauv lub interfacial bonding zog thiab ceev ntawm cov hlau txheej. Cov txheej txheem muaj xws li molybdenum-manganese txoj kev thiab cov txheej txheem hlau nquag, uas siv siab -kub sintering kom cov hmoov hlau mus rau diffuse thiab sib txuas nrog cov ceramic matrix, yog li tsim cov txheej txheem hloov pauv ruaj khov.
Txawm li cas los xij, ceramic-rau- kev sib txuas ntawm cov hlau tsis yog ib qho yooj yim txheej txheem stacking; Nws yog qhov tseem ceeb ntawm cov txheej txheem nyuaj uas suav nrog cov ntaub ntawv tshawb fawb, thermodynamics, thiab interface engineering. Ua ntej, qhov sib txawv ntawm thermal expansion coefficients ntawm ceramics thiab hlau yog ib qho ntawm cov ua rau ntawm interfacial tawg. Thaum lub sij hawm cua sov thiab cua txias, qhov contraction thiab expansion ntawm ob cov ntaub ntawv yog asynchronous, generating thermal stress ntawm lub interface. Yog li ntawd, thaum tsim cov txheej txheem metallized ceramic, feem ntau nws yog qhov tsim nyog los ua kom paub cov txheej txheem hloov pauv nruab nrab lossis xaiv cov khoom siv hlau nrog cov coefficient ze dua los daws cov teeb meem kev ntxhov siab.
Qhov thib ob, cov ntaub ntawv ceramic lawv tus kheej muaj hluav taws xob tsis tshua muaj hluav taws xob, ua rau kev sib txuas ncaj qha siv cov txheej txheem vuam tsis yooj yim. Yog li ntawd, ib txheej conductive yuav tsum xub tsim nyob rau saum npoo los ntawm metallization ua ntej tom ntej welding los yog brazing tuaj yeem ua tiav. Qhov no yog ib qho ntawm cov laj thawj tseem ceeb vim li cas Alumina Metallized Ceramics tau siv dav hauv kev ntim khoom hluav taws xob. Tsis tas li ntawd, ceramics yog nkig thiab muaj kev txwv thermal shock tsis kam. Thaum lub sij hawm vuam txheej txheem, kev tswj nruj ntawm qhov ntsuas kub thiab txias txias yog qhov tsim nyog kom tsis txhob tawg lossis kev puas tsuaj ntawm cov qauv.
Los ntawm cov txheej txheem tswj kev pom, cov yam ntxwv cuam tshuam rau metallization zoo feem ntau suav nrog kev tsim metallization, sintering kub thiab tuav lub sijhawm, thiab microstructure ntawm txheej hlau. Kev tsim qauv tsim nyog yog lub hauv paus rau kev ua tiav High-Lub Zog Metallized Ceramic Cheebtsam. Qhov sib txawv ntawm cov hmoov hlau thiab cov khoom ntxiv ncaj qha cuam tshuam rau qhov kawg kev sib koom ua ke lub zog thiab conductivity. Sintering kub feem ntau muab faib ua qis, nruab nrab, siab, thiab ultra- kub ntau yam. Cov kub uas qis dhau yuav ua rau muaj qhov tsis txaus ntawm cov khoom siv hlau, thaum qhov kub thiab txias siab dhau yuav ua rau cov txheej hlau ua embritttled lossis detach. Yog li, kev tswj xyuas meej ntawm sintering nkhaus yog qhov tseem ceeb rau kev ua haujlwm ruaj khov.
Regarding the microstructure, a high-quality metallization layer should exhibit a dense and uniform microstructure, with smooth transitions between interfaces and no obvious brittle phases. Cov qauv no tsis tsuas yog txhim kho vuam kev ntseeg tau tab sis kuj tseem cuam tshuam kev tawg tawg, txuas ntxiv kev pabcuam tag nrho lub neej. Piv txwv li, nyob rau hauv Precision Metallized Alumina Ceramic Cheebtsam, optimizing hmoov particle loj tis thiab sintering txheej txheem feem ntau tsim ib tug nruam, ntom conductive network nyob rau hauv cov hlau txheej, ua tau raws li qhov xav tau ntawm siab - daim ntawv thov kev ntseeg siab.
Tsis tas li ntawd, cov txheej txheem tsis xws li hmoov particle loj, txheej txheej, thiab txheej txheej kuj tseem cuam tshuam rau qhov zoo kawg nkaus. Cov hmoov uas zoo heev yog nquag mus rau agglomeration, cuam tshuam rau txheej txheej uniformity; hmoov uas yog ntxhib heev yuav tsum tau siab dua sintering kub, ua rau nws nyuaj rau tswj lub qhov rais txheej txheem. Yog li ntawd, nyob rau hauv zus tau tej cov High Purity Alumina Precision Advanced Ceramic Metallization Parts, nruj txheej txheem kev txheeb xyuas thiab parameter optimization feem ntau yuav tsum tau los xyuas kom meej qhov sib xws thiab stability ntawm precision machining rau txhua batch ntawm Alumina ceramic qhov chaw.
Hauv cov ntsiab lus, ceramic metallization thev naus laus zis ua haujlwm tseem ceeb txuas rau ob hom khoom siv nrog ntau yam khoom sib txawv, thiab nws theem kev loj hlob ncaj qha cuam tshuam rau tag nrho cov kev ua tau zoo thiab kev ntseeg siab ntawm high-kawg hluav taws xob tsim khoom. Nrog kev nce qib txuas ntxiv hauv cov ntaub ntawv tshawb fawb thiab kev tsim khoom, ceramic metallization yuav ua rau pom kev siv zog ntau dua hauv cov hluav taws xob ntau dua, ntau cov qauv, thiab qhov xav tau ntau dua.
