Nyob rau hauv lub ntiaj teb ntawm semiconductor kev tsim khoom, cov khoom siv wafefer yog siv los tsim kev sib xyaw ua ke, cov microprocessors, chips nco, thiab lwm yam hluav taws xob. Cov cuab yeej siv no yuav tsum muaj kev ruaj khov thiab ruaj khov rau kom ntseeg tau tias yog thiab ua kom meej.
Lub tshuab granite yog ib qho ntawm cov tshuab nrov uas siv nyob rau hauv wafer ua khoom siv. Raws li lub npe qhia, nws yog tsim los ntawm granite, ib txwm tshwm sim pob zeb uas paub rau nws lub zog siab thiab nruj.
Granite tshuab lub hauv paus muaj ntau qhov zoo thaum muab ntau hom kev sib piv rau lwm hom tshuab lub hauv paus zoo li cam khwb cia hlau, hlau, lossis txhuas. Ib qho ntawm cov txiaj ntsig tseem ceeb yog nws cov khoom siv damping zoo heev. Damping hais txog kev muaj peev xwm ntawm cov khoom siv kom nqus cov kev co thiab txo cov suab nrov. Granite muaj qhov chaw resonant tsawg, uas txhais tau tias nws tuaj yeem dampen dibrations zoo dua li lwm cov ntaub ntawv. Raws li qhov tshwm sim, cov khoom siv wafefer ua tau tuaj yeem ua haujlwm ntawm kev nrawm dua, thiab cov chips tsim tawm yog qhov tseeb dua thiab tsis tshua muaj qhov yuam kev.
Lwm qhov zoo dua ntawm lub tshuab granite yog nws qhov seem ruaj khov. Granite muaj cov coefficient ntawm thermal expansion, uas txhais tau tias nws tsis nthuav dav lossis cog lus nrog qhov kub hloov. Cov cuab yeej no kom ntseeg tau tias lub wafefer ua cov khoom siv tswj hwm nws qhov precision txawm tias raug hloov pauv ib puag ncig.
Granite kuj tseem muaj kev tiv taus hnav thiab kua muag thiab tsis corrode yooj yim. Cov cuab yeej no ua rau nws zoo tagnrho rau kev siv nyob rau hauv ib puag ncig muaj kev muaj kev nyab xeeb ib puag ncig, qhov twg wafer ua cov cuab yeej siv tau raug rau cov tshuaj lom neeg thiab cov khoom siv tsis zoo. Granite kuj yog yooj yim los ntxuav thiab tswj, ua rau nws xaiv tau zoo rau kev nyab xeeb cov khoom siv.
Hauv kev xaus, lub tshuab granite yog qhov tseem ceeb ntawm txhua yam khoom siv tiv thaiv. Nws cov khoom siv damping zoo heev, seem ruaj khov, thiab kev tsis kam hnav thiab kua muag ua rau nws xaiv zoo tshaj plaws rau cov hluav taws xob hluav taws xob. Nrog rau kev thov txuas ntxiv rau cov thev naus laus zis, qhov tseem ceeb ntawm cov tshuab granite yuav tsuas yog loj hlob hauv lub neej yav tom ntej.
