Granite yog ib yam khoom siv uas siv ntau hauv cov khoom siv semiconductor vim nws qhov ruaj khov zoo heev, qhov nyuaj, thiab qhov coefficient qis ntawm thermal expansion. Txawm li cas los xij, zoo li txhua yam khoom siv, cov khoom granite yooj yim hnav thiab ua tsis tiav raws sijhawm. Txhawm rau tiv thaiv cov kev ua tsis tiav no, nws yog ib qho tseem ceeb kom nkag siab txog qhov ua rau hnav thiab ua cov kev ntsuas ua ntej kom tiv thaiv kev puas tsuaj rau cov khoom siv.
Ib qho ua rau cov khoom granite tsis ua haujlwm yog kev hnav khaub ncaws. Hom kev hnav khaub ncaws no tuaj yeem tshwm sim vim ntau yam xws li qhov tsis zoo ntawm qhov chaw, qhov chaw saum npoo, thiab kev ua qias tuaj. Kev raug tshuaj lom neeg ntev thiab qhov kub siab kuj tseem tuaj yeem ua rau muaj kev hnav khaub ncaws. Txhawm rau tiv thaiv kev hnav khaub ncaws thiab ua kom lub neej ntawm cov khoom granite ntev dua, nws yog ib qho tseem ceeb uas yuav tsum tshuaj xyuas thiab tswj cov chaw tsis tu ncua. Kev siv cov tshuaj tiv thaiv thiab kev ntxuav tsis tu ncua kuj tseem tuaj yeem pab txo qhov kev puas tsuaj los ntawm kev raug tshuaj lom neeg.
Kev qaug zog ntawm cov khoom granite yog lwm qhov ua rau tsis ua haujlwm. Hom kev hnav no tshwm sim vim muaj qhov tsis sib xws ntawm cov coefficients ntawm kev nthuav dav thermal ntawm granite thiab cov khoom sib ze. Raws sijhawm, kev rov ua dua thermal cycling tuaj yeem ua rau muaj kab nrib pleb thiab tawg hauv granite. Txhawm rau tiv thaiv kev qaug zog thermal, nws yog ib qho tseem ceeb kom xaiv cov ntaub ntawv nrog cov coefficients ntawm kev nthuav dav thermal sib xws thiab xyuas kom meej tias cov khoom siv ua haujlwm hauv qhov kub thiab txias pom zoo. Kev tshuaj xyuas thermal tsis tu ncua kuj tseem tuaj yeem pab txheeb xyuas cov teeb meem ua ntej lawv ua rau muaj kev puas tsuaj loj.
Lwm txoj hauv kev los tiv thaiv kev ua tsis tiav hauv cov khoom granite yog los ntawm kev ua qauv siab heev thiab kev simulation. Finite element analysis (FEA) tuaj yeem siv los kwv yees tus cwj pwm ntawm cov khoom granite nyob rau hauv ntau yam kev thauj khoom thiab ib puag ncig. Los ntawm kev sim cov xwm txheej ua tsis tiav, cov engineers tuaj yeem txheeb xyuas cov cheeb tsam ntawm kev ntxhov siab siab thiab tsim cov tswv yim txo qis kom tsim nyog. FEA kuj tseem tuaj yeem siv los ua kom zoo dua cov qauv geometries thiab cov khoom siv khoom kom txhim kho kev hnav tsis kam thiab txo qhov ua tsis tiav.
Xaus lus, kev tiv thaiv kev ua tsis tiav hauv cov khoom granite hauv cov khoom siv semiconductor xav tau ntau txoj hauv kev. Kev saib xyuas thiab kev ntxuav kom zoo, kev xaiv cov khoom siv, thiab cov txheej txheem ua qauv tuaj yeem pab txo qhov kev pheej hmoo ntawm kev hnav thiab kev puas tsuaj. Los ntawm kev siv txoj hauv kev ua ntej rau kev saib xyuas cov khoom granite, cov chaw tsim khoom siv semiconductor tuaj yeem txo lub sijhawm tsis ua haujlwm, txuag nyiaj, thiab txhim kho kev ua haujlwm ntawm cov khoom siv tag nrho.
