Granite vs. Lwm Cov Khoom Siv: Qhov twg yog qhov zoo tshaj plaws Wafer Cutting Equipment Base?

Hauv kev tsim khoom siv semiconductor, kev txiav wafer yog ib qho txheej txheem tseem ceeb uas xav tau qhov tseeb tshaj plaws. Kev xaiv cov khoom siv rau lub hauv paus khoom siv cuam tshuam rau kev ua tau zoo. Cia peb piv granite nrog lwm cov ntaub ntawv siv ntau kom pom vim li cas nws feem ntau zoo tshaj plaws rau cov khoom siv txiav wafer.
Granite: Ib Qho Txiav Tshaj Qhov So
Kev Ruaj Ntseg: Granite, nrog qhov ceev nyob ib ncig ntawm 3100 kg / m³ zoo li ZHHIMG® qhov kev muab, muab kev ruaj ntseg zoo heev. Nws cov qauv ruaj khov txo qhov kev co thaum lub sijhawm txiav wafer. Qhov sib piv, cov ntaub ntawv xws li txhuas yuav yooj yim txav mus los hauv qab kev ntxhov siab ntawm kev ua haujlwm txiav ceev ceev. Qhov kev ruaj khov no ua kom ntseeg tau tias cov cuab yeej txiav tseem nyob hauv qhov chaw raug, ua rau muaj kev txiav raug thiab cov wafers zoo.

Kev Tiv Thaiv Kub: Granite muaj cov coefficient nthuav dav thermal qis. Hauv kev txiav wafer, qhov twg qhov kub hloov pauv tuaj yeem tshwm sim vim yog cua sov tsim los ntawm cov txheej txheem txiav lossis qhov chaw tsim khoom, granite lub thermal stability yog qhov zoo. Nws tsis nthuav dav lossis cog lus ntau nrog kev hloov pauv kub, tswj kev sib dhos ntawm cov khoom siv txiav. Cov hlau zoo li hlau, ntawm qhov tod tes, tuaj yeem muaj kev nthuav dav thermal ntau dua, uas ua rau tsis sib xws thiab txiav tsis raug.
Kev Tiv Thaiv Kev Co: Cov yam ntxwv ntawm kev co ntuj - kev tiv thaiv kev co ntawm granite yog qhov zoo kawg nkaus. Thaum txiav wafer, kev co tuaj yeem ua rau lub cuab yeej txiav tawm ntawm nws txoj kev npaj, ua rau chipping lossis txiav tsis sib npaug. Granite nqus tau zoo thiab tshem tawm cov kev co no, tsim kom muaj kev txiav du dua. Cov ntaub ntawv xws li cov yas - ua los ntawm cov khoom sib xyaw tsis muaj qhov kev co no - kev tiv thaiv kev co, ua rau lawv tsis haum rau kev txiav wafer siab.
Piv nrog Cast Iron
Cov hlau cam khwb cia tau yog ib qho kev xaiv ib txwm rau cov hauv paus tshuab. Txawm li cas los xij, nws muaj nws cov kev txwv piv rau granite. Thaum cov hlau cam khwb cia muab qee qhov kev ruaj khov, nws hnyav dua li granite piv rau nws lub zog. Qhov hnyav ntxiv no tuaj yeem ua rau muaj kev cov nyom thaum lub sijhawm teeb tsa khoom siv thiab kev txav mus los. Tsis tas li ntawd, cov hlau cam khwb cia muaj kev cuam tshuam ntau dua rau kev xeb dhau sijhawm, tshwj xeeb tshaj yog nyob rau hauv cov chaw tsim khoom semiconductor uas cov tshuaj lom neeg yuav muaj nyob. Granite, ua cov tshuaj lom neeg inert, tsis raug kev txom nyem los ntawm qhov teeb meem no, ua kom ntseeg tau tias muaj kev ruaj khov thiab kev ntseeg siab mus sij hawm ntev.
Cov Ntaub Ntawv Tawm Tsam Marble
Tej zaum ib txhia yuav xav tias marble yog lwm txoj hauv kev xaiv, tab sis nws tsis zoo rau ntau yam khoom siv txiav wafer. Marble muaj qhov ceev tsawg dua thiab feem ntau tsis ruaj khov dua li granite. Nws kuj muaj qhov porous ntau dua, uas ua rau nws yooj yim raug puas tsuaj los ntawm cov dej noo thiab cov tshuaj lom neeg hauv qhov chaw tsim khoom. Hauv kev txiav wafer, qhov twg qhov tseeb thiab kev ruaj khov yog qhov tseem ceeb, cov khoom siv lub cev ntawm marble tsis phim cov kev xav tau zoo li granite ua.
Xaus lus, thaum nws los txog rau kev xaiv cov khoom siv rau cov khoom siv txiav wafer, granite, tshwj xeeb tshaj yog cov granite zoo li ZHHIMG® muab, sawv tawm. Nws qhov kev ruaj khov, kev tiv thaiv thermal, thiab kev co - damping muaj peev xwm ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev ua tiav qhov kev txiav siab siab uas xav tau hauv semiconductor wafer. Thaum muaj lwm cov ntaub ntawv muaj, granite qhov kev sib xyaw ua ke ntawm cov yam ntxwv ua rau nws muaj qhov ntug meej hauv daim ntawv thov no.
