Lub zog ruaj khov thiab lub peev xwm thauj khoom ntawm granite hauv cov khoom siv semiconductor yog dab tsi?

Lub hauv paus granite tau siv dav hauv cov khoom siv semiconductor vim nws qhov ruaj khov zoo heev thiab muaj peev xwm nqa tau. Raws li lub pob zeb ntuj, granite paub txog nws qhov ruaj khov thiab tiv taus kev hnav thiab rhuav. Nws tuaj yeem tuav cov khoom hnyav yam tsis muaj kev hloov pauv lossis tawg, ua rau nws yog cov khoom siv zoo meej rau cov khoom siv precision siab uas xav tau kev ruaj khov thiab raug.

Qhov ruaj khov ntawm granite puag hauv cov khoom siv semiconductor yog ua tiav los ntawm nws cov khoom muaj nqis. Granite muaj cov coefficient qis ntawm thermal expansion, txhais tau tias nws tsis nthuav dav lossis cog lus ntau nrog kev hloov pauv ntawm qhov kub thiab txias. Qhov no ua kom ntseeg tau tias cov khoom siv mounted rau ntawm granite puag tseem nyob rau hauv qhov chaw ruaj khov txawm tias thaum qhov kub hloov pauv, txo qhov kev pheej hmoo ntawm kev tsis sib haum xeeb lossis kev ua tsis tiav ntawm cov khoom siv.

Tsis tas li ntawd xwb, granite muaj cov khoom zoo uas ua rau nws tsis co, uas txhais tau tias nws tuaj yeem nqus tau kev co thiab txo qhov cuam tshuam ntawm cov yam sab nraud xws li cua lossis av qeeg. Qhov no txo ​​qhov kev txav tsis xav tau thiab txhim kho qhov tseeb ntawm cov khoom siv, ua rau nws haum rau cov ntawv thov uas qhov tseeb yog qhov tseem ceeb, xws li kev tsim khoom semiconductor.

Lub peev xwm thauj khoom ntawm lub hauv paus granite kuj tseem ceeb heev. Granite yog ib qho ntawm cov khoom siv ntuj muaj zog tshaj plaws, nrog lub zog compressive txog li 300 MPa. Qhov no txhais tau tias nws tuaj yeem dais cov khoom hnyav yam tsis tawg lossis deforming, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv uas xav tau lub hauv paus ruaj khov. Cov pob zeb granite tuaj yeem txiav kom loj me thiab ua kom raug raws li qhov xav tau ntawm cov khoom siv sib txawv, ua kom ntseeg tau tias muaj qhov haum zoo meej thiab kev txhawb nqa ruaj khov.

Ntxiv mus, lub hauv paus granite muaj cov tshuaj tiv thaiv zoo thiab tsis yooj yim rau ntau yam tshuaj lom neeg xws li cov kua qaub, alkalis, thiab cov kuab tshuaj. Qhov no ua rau nws tsim nyog siv rau hauv cov chaw muaj tshuaj lom neeg hnyav yam tsis muaj kev puas tsuaj lossis cuam tshuam nrog cov tshuaj. Nrog kev ntxuav thiab kev saib xyuas tsis tu ncua, lub hauv paus granite tuaj yeem kav ntev ntau xyoo, ua rau nws yog qhov kev xaiv pheej yig rau cov khoom siv semiconductor.

Xaus lus, qhov ruaj khov thiab lub peev xwm thauj khoom ntawm granite puag ua rau nws yog qhov kev xaiv nrov rau cov khoom siv semiconductor. Nws cov yam ntxwv xws li kev nthuav dav thermal tsawg, cov khoom zoo damping, lub zog compressive siab, thiab kev tiv thaiv tshuaj lom neeg ua kom cov khoom siv ruaj khov thiab raug raws sijhawm. Yog tias kev saib xyuas kom zoo, granite puag tuaj yeem muab kev txhawb nqa ntev rau cov txheej txheem tsim khoom semiconductor.
