Aluminum Silicon Metal Packages

LUS QHIA:
Si / Al alloys rau cov pob khoom hluav taws xob feem ntau xa mus rau eutectic alloy cov ntaub ntawv nrog cov ntsiab lus silicon ntawm 11% rau 70%. Nws cov ntom ntom tsawg, cov coefficient ntawm thermal nthuav tuaj yeem sib phim rau cov nti thiab cov dej hauv av, thiab nws muaj peev xwm ua kom kub siab ua kom zoo dua. Nws machining kev ua tau kuj zoo tagnrho. Yog li ntawd, Si / Al alloys muaj peev xwm loj heev hauv kev lag luam ntim hauv tshuab hluav taws xob.

MAIN NTA:
• Kev tshem tawm kub ceev thiab lub siab thermal conductivity tuaj yeem daws cov teeb meem kub ua kom tsis muaj qhov sib txig hauv kev txhim kho cov khoom siv hluav taws xob ntau.
• Cov coefficient ntawm thermal expansion yog tswj tau, uas ua kom nws phim cov nti, zam kom tsis txhob muaj kev kub ntxhov ntau dhau uas tuaj yeem ua rau lub cuab yeej poob.
• Tsis tshua muaj ntau

Pob zeb diamond / tooj liab, Pob Zeb Diamond / Aluminium

DiamondCopper, DiamondAluminum

LUS QHIA:
Pob zeb diamond / tooj liab thiab Pob zeb diamond / Aluminium yog cov khoom siv sib xyaw nrog pob zeb diamond raws li theem txhim kho thiab tooj liab lossis txhuas ua cov khoom siv hauv cov khoom siv. Cov no yog cov nqi sib tw heev thiab cog lus zoo rau kev ntim khoom hluav taws xob. Rau ob lub pob zeb diamond / tooj liab thiab pob zeb diamond / aluminium hlau tsev, cov thermal conductivity ntawm nti cheeb tsam yog ≥500W / (m • K) -1, txaus siab rau qhov ua tau zoo ntawm qhov kub siab ua kom tsis taus ntawm Circuit Court. Nrog cov kev tshawb fawb txuas ntxiv, cov tsev vaj tsev no yuav ua lub luag haujlwm tseem ceeb hauv kev lag luam ntawm ntim khoom lag luam.

MAIN NTA:
• Muaj cov thermal conductivity zoo
• Cov coefficient ntawm kev nthuav dav thermal (CTE) tuaj yeem tswj tau los ntawm kev hloov qhov huab hwm coj feem ntawm cov pob zeb diamond thiab Cu cov ntaub ntawv
• Tsis tshua muaj ntau
• Cov platability zoo thiab kev ua haujlwm, hlau txiav, sib tsoo thiab kub plating tuaj yeem nqa tawm

AlN substrate

AlN substrate

LUS QHIA:
Aluminium nitride ceramic yog cov khoom siv ua paj ntaub. Nws muaj cov cua sov zoo tshaj, cov tshuab thiab hluav taws xob, xws li cov hluav taws xob muaj hluav taws xob ntau, qhov txheeb ze me me ntawm qhov tsis tu ncua, qhov tawm ntawm cov hluav taws xob txuas ntxiv nrog cov sib xyaw ua ke nrog silicon, hluav taws xob zoo hluav taws xob, thiab tsis ntom ntom. Nws yog non-toxic thiab muaj zog.
