AIN Ceramic Substrate Taw Qhia

AIN ceramic substrate, uas yog aluminium nitride ceramic substrate, yog cov khoom siv siab heev nrog cov khoom zoo heev thiab kev siv dav.
1. Cov khoom siv
High Thermal Conductivity: AIN ceramic substrate muaj cov thermal conductivity zoo heev. Nws tuaj yeem ncav cuag qhov tseem ceeb hauv thaj tsam ntawm 170 - 230 W/(m·K) lossis siab dua hauv qee kis. Qhov no ua rau nws ua tau zoo dissipate tshav kub uas tsim los ntawm cov khoom siv hluav taws xob uas txuas rau nws.
Hluav taws xob rwb thaiv tsev zoo: Nrog rau nws cov thermal zoo, AIN ceramic yog ib qho hluav taws xob zoo heev. Cov cuab yeej no tso cai rau nws siv rau hauv cov tshuab hluav taws xob yam tsis muaj kev cuam tshuam luv luv lossis hluav taws xob cuam tshuam, ua rau nws zoo tagnrho rau cov ntawv thov uas yuav tsum muaj kev sib cais ntawm cov cua sov thiab hluav taws xob.
Matching Thermal Expansion Coefficient: Lub thermal expansion coefficient ntawm AIN yog zoo - txuam nrog cov ntaub ntawv semiconductor zoo li silicon. Qhov no txo ​​cov thermal stress thaum lub sij hawm kub variations, txhim khu kev ntseeg ntawm kev sib txuas ntawm substrate thiab cov khoom siv semiconductor.
2. Cov txheej txheem tsim khoom
Kev tsim khoom ntawm AIN ceramic substrate muaj ob peb kauj ruam. High - zoo AIN hmoov yog thawj zaug npaj los ntawm txoj kev xws li kev txo qis carbothermal. Tom qab ntawd, ntau yam sintering cov txheej txheem xws li kub - nias sintering, pressureless sintering, los yog spark plasma sintering yog ua hauj lwm los tsim cov ntom ceramic substrate. Cov txheej txheem no yuav tsum muaj kev tswj xyuas qhov tsis zoo los xyuas kom meej lub substrate zoo thiab kev ua tau zoo.
3. Cov ntawv thov
AIN ceramic substrate pom kev siv dav hauv kev lag luam hluav taws xob. Nws yog dav siv nyob rau hauv lub hwj chim electronics modules, LED ntim, thiab high-speed integrated circuits. Hauv hluav taws xob hluav taws xob, nws pab txhim kho lub zog ceev thiab kev ntseeg siab ntawm cov qauv los ntawm kev tswj cov cua sov kom zoo. Nyob rau hauv LED ntim, nws ua raws li ib tug npaum li cas ntawm tshav kub dab dej kom ntev lub neej ntawm LEDs. Zuag qhia tag nrho, AIN ceramic substrate plays lub luag haujlwm tseem ceeb hauv kev txhim kho cov khoom siv hluav taws xob niaj hnub ua tau zoo.
Peb yog cov chaw tsim khoom, chaw tsim khoom thiab chaw muag khoom tshwj xeeb hauv ceramics hauv Suav teb. Cov ceramics peb tsim yog: Silicon carbide, aluminium nitride, alumina, ultrapure alumina, yttria, zirconia, High-purity thiab high-performance boron nitride ceramics zirconia toughened alumina (ZTA), alumina toughened zirconia (ATZ), silicon nitride thiab lwm yam reinforced ceramics, composite ceramics thiab siab ceramics.
