Cov khoom ntim

Khoom Zoo

Cov ntaub ntawv ntim khoom siv feem ntau yog yas, hlau, ceramic. Yas encapsulation plhaub feem ntau yog ua los ntawm epoxy resin, tab sis vim muaj qhov sib txawv ntawm thermal expansion ntawm epoxy resin thiab thermal conductivity tsis zoo, feem ntau siv silica los ua cov muab tub lim kom txo nws cov coefficient ntawm thermal expansion thiab txhim kho thermal conductivity. Tam sim no, cov hnab yas tseem yog daim ntawv tseem ceeb ntawm kev ntim khoom, tab sis nyob rau hauv cov thermal conductivity thiab kev ntseeg siab ntawm cov sij hawm siab dua, kev siv cov pob zeb ceramic, hauv qee qhov tshwj xeeb kuj tseem siv rau hauv cov pob hlau.

Piv txwv li, qee cov tub rog modules yuav siv cov ntim ceramic, cov khoom siv hluav taws xob infrared yuav siv cov ntim hlau. Lub neej yav tom ntej ntawm cov khoom siv hlau-raws li cov khoom ntim yuav ua rau kev ua haujlwm siab, tsis tshua muaj nqi, tsis tshua muaj siab thiab kev sib koom ua ke ntawm kev txhim kho. Lub teeb yuag, siab thermal conductivity thiab CTE-matched Si / Al, SiC / Al alloys yuav muaj kev cia siab zoo.

Nrog rau microelectronics ntim tshuab rau ntau lub chips (MCM) thiab nto mount technology (SET) txoj kev loj hlob, cov tsoos ntim cov ntaub ntawv tsis muaj peev xwm ua tau raws li qhov yuav tsum tau ntawm high-density ntim, txoj kev loj hlob ntawm cov ntaub ntawv sib xyaw tshiab yuav tsum tau ntim khoom siv hluav taws xob. cov ntaub ntawv yuav yog multi-phase composite kev taw qhia. Cov hauv qab no yog kev sib piv ntawm kev ua tau zoo ntawm cov khoom siv ntim khoom siv hlau feem ntau:

Cov khoom ntim khoom siv feem ntau muaj xws li yas, hlau, thiab ceramics. Lub plhaub ntim yas yog tsim los ntawm epoxy resin, tab sis vim yog qhov thermal expansion coefficient thiab tsis zoo thermal conductivity ntawm epoxy resin, silicon dioxide feem ntau yog siv los ua cov muab tub lim kom txo nws cov thermal expansion coefficient thiab txhim kho thermal conductivity. Tam sim no, cov ntim yas tseem yog daim ntawv ntim tseem ceeb, tab sis cov ntim khoom siv ceramic yuav raug siv nyob rau hauv lub sijhawm uas muaj kev kub ntxhov siab thiab kev ntseeg siab, thiab cov ntim hlau kuj tseem siv rau qee qhov tshwj xeeb.
