Kev Taw Qhia Txog Khoom

LubPob Zeb Diamond-Tooj Liab Composite (Cu-Diamond)yog ib qhocov khoom siv tswj kev kub siab heevuas muab cov khoom siv hluav taws xob zoo tshaj plaws hauv ntiaj teb ua ke -pob zeb diamond— nrog rau cov khoom siv hluav taws xob thiab khoom siv kho tshuab zoo tshaj plaws ntawmtooj liab.
Tsim los rau cov khoom siv hluav taws xob thiab cov khoom siv fais fab uas niaj hnub nim no, cov khoom sib xyaw no ua tiav qhov sib npaug tshwj xeeb ntawmkev ua tau zoo heev ntawm cov cua sov, kev nthuav dav ntawm cov cua sov uas tswj tau, thiabkev ruaj khov kho tshuab, ua kom muaj kev ua haujlwm txhim khu kev qha txawm tias nyob rau hauv qhov chaw kub tshaj plaws.

Tsis zoo li cov khoom siv tooj liab, tungsten, lossis molybdenum, cov khoom siv pob zeb Diamond-Copper xa cov khoom zoo sib xws.txog li ob npaug ntawm cov thermal conductivitythaum txo qhov hnyav, ua rau lawv yog qhov kev xaiv zoo tshaj plaws rauCov khoom ntim semiconductor, cov tshuab laser, cov khoom siv hluav taws xob aerospace, thiab cov modules LED muaj zog heev.

Cov Ntsiab Cai ntawm Cov Khoom Siv

Lub plawv ntawm cov khoom sib xyaw ua ke yogcov pob zeb diamond me meuniformly embedded nyob rau hauv ib tugtooj liab matrix.
Txhua lub pob zeb diamond ua haujlwm ua lub dab dej cua sov me me, kis cua sov sai sai, thaum lub matrix tooj liab ua kom muaj kev xa hluav taws xob thiab kev ua kom ruaj khov.
Los ntawm cov txheej txheem tsim khoom siab heev - suav nrogkev nkag mus rau hauv lub tshuab nqus tsev, tshuaj pleev xim, thiabKev siv plasma sintering (SPS)— ib qho kev sib txuas lus zoo thiab ruaj khov tau tsim, lav qhov kev ntseeg tau mus sij hawm ntev hauv qab kev hloov pauv thermal tas mus li.

Txo qhov qaug zog ntawm cua sov

Cov Lus Nug Txog Cov Tsom Iav Quartz

Q1: Cov khoom sib xyaw Cu-Diamond puas tuaj yeem hloov kho rau cov ntaub ntawv tshwj xeeb?
Yog. Qhov feem pua ntawm pob zeb diamond thiab CTE tuaj yeem kho kom raug kom phim Si, GaN, lossis SiC-based devices.

Q2: Puas yog xav tau metallization ua ntej soldering?
Yog. Kev siv hlau nplaum rau saum npoo (Ni/Au, Ti/Ni/Au) yog qhov pom zoo kom ntseeg tau tias muaj kev sib txuas zoo heev thiab tsis tshua muaj kev tiv taus cua sov.

Q3: Nws ua haujlwm li cas hauv qab qhov kub siab lossis kub hnyiab?
Pob zeb diamond qhov kev sib kis cua sov zoo tshaj plaws ua kom muaj kev sib npaug ntawm qhov kub thiab txias sai, ua rau nws zoo tagnrho rau cov khoom siv zaus siab thiab cov khoom siv pulse-loaded.

Q4: Qhov kub siab tshaj plaws ua haujlwm yog dab tsi?
Cov khoom sib xyaw ua ke tseem ruaj khov mus txog rau600°Cnyob rau hauv inert lossis vacuum ib puag ncig, nyob ntawm seb lub txheej thiab kev sib txuas interface.
