Alumina Ceramic Substrate China

Nrog rau kev tsim cov khoom siv hluav taws xob, lub zog tau nce dua thiab siab dua thiab cov khoom tau txais qis dua thiab me dua, yog li cov tseev kom muaj kev ua tau zoo hauv thermal conductors tau nce ntau dua thiab siab dua, cov ntaub ntawv ua ntej rwb thaiv tsev thermal tau muaj ntau dua thiab tsis tuaj yeem ua tau raws Cov. Hauv qhov no, alumina ceramic substrate ua lub siab thermal conductivity thiab siab rwb thaiv tsev ceramic khoom, nrog 25W / mk thermal conductivity thiab 17KV dielectric lub zog, tau dhau los ua ntau dua thiab nrov dua substrate xaiv ntawm ntau cov cuab yeej siv zog, piv nrog cov ntawv silicon. substrate nrog thermal conductivity tsuas yog 0.6W / mk, thiab dielectric lub zog ntawm alumina Al2O3 substrate kuj tsuas yog 2KV. Relying ntawm qhov tshwj xeeb kev ua tau zoo thiab tus nqi siab / kev ua piv zoo tshaj, daim ntawv thov ntawm alumina substrate tau dhau los ua qhov dav dua thiab dav dua. Raws li peb txhua tus paub, ceramic yog puas yooj yim, tab sis peb lub tuam txhab tso siab rau cov cuab yeej siv siab tshiab thiab ntau xyoo ntawm kev paub ntau lawm, lub zog ntawm kev tsim cov kab xev casting alumina substrates ntawm lub hauv paus pib ntawm lub zog zoo heev!

Yog tias koj cov khoom muaj cov teeb meem nram qab no, koj tuaj yeem xaiv alumina sheet substrate.

1. Ntau tshaj li ib nrab ib teev tom qab pib, nws muaj lub cauj roj, hlawv yeeb nkab tshwm sim, xav tau kev soj ntsuam Circuit Court tsis muaj qhov txawv txav.

2. Lub hwj chim rau ib lub sijhawm, ntsuas lub raj lub raj xa mus los ntawm ib txwm mus rau qhov txawv txav deformation xeev.

3. Lub tshuab xuas tes kov yog qhov kub heev, thiab lub tshuab hluav taws xob kub tsis ua kom cov xwm txheej.

4. Tom qab cov khoom muag muag, ntev ntev, tus neeg yuav khoom xa rov qab lub tshuab yeeb-tshuab.

5. Cov cuab yeej siv rau kev rwb thaiv tsev thermal xav tau siab.
