Granite lub hauv paus yog feem ntau siv nyob rau hauv cov khoom siv semiconductor vim nws cov khoom siv hluav taws xob zoo heev, thermal stability, thiab tsawg coefficient ntawm thermal expansion. Txawm li cas los xij, zoo li lwm yam khoom siv, cov tshuab granites tuaj yeem tsim kev ua txhaum uas tuaj yeem cuam tshuam kev ua haujlwm ntawm cov cuab yeej ua semiconductor. Hauv tsab xov xwm no, peb yuav hais txog qee qhov kev ua txhaum ntawm granite hauv paus hauv cov cuab yeej ua haujlwm sib dhos thiab muab cov kev daws teeb meem.
Txhaum # 1: Nto Doormations
Nto deformations yog qhov kev ua yuam kev tshaj plaws hauv granite hauv paus hauv cov khoom siv semiconductor. Thaum lub hauv paus granite yog raug hloov mus rau qhov kub hloov lossis hnyav thauj khoom, nws tuaj yeem txhim kho cov deformation nto, xws li warps, twists, thiab pob. Cov kev deformations no tuaj yeem cuam tshuam nrog cov qib siab thiab qhov tseeb ntawm cov cuab yeej ua semiconductor.
Kev daws: Nto Kho
Sab saum npoo kho tau tuaj yeem pab txo cov ntsej muag nto sab hauv granite puag. Txoj kev kho cov txheej txheem cuam tshuam nrog kev sib tsoo ntawm cov npoo ntawm Granite Base los kho nws cov tiaj tiaj thiab du. Xav tau kev saib xyuas yuav tsum tau them rau xaiv cov cuab yeej sib tsoo thiab cov abrasive siv los xyuas kom meej tias qhov tseeb yog tswj.
Txhaum # 2: tawg
Cov kab nrib pleb tuaj yeem txhim kho hauv granite hauv paus raws li qhov tshwm sim ntawm thermal cycling, cov khoom siv hnyav, thiab machining yuam kev. Cov kab nrib pleb no tuaj yeem ua rau cov txheej txheem instability thiab cuam tshuam rau qhov precision ntawm cov cuab yeej ua semiconductor.
Kev daws: txhaws thiab kho
Txau thiab kho cov kab nrib pleb tuaj yeem pab txhawb qhov ruaj khov thiab precision ntawm granite puag. Cov txheej txheem kho feem ntau yuav cuam tshuam nrog cov kab nrib pleb uas muaj epoxy, uas yog tom qab ntawd kho tau lub zog ntawm granite nto. Qhov chaw sib raug zoo yog tom qab ntawd rov qab los ntawm kev kho kom ncaj thiab du.
Txhaum # 3: delamination
Delamination yog thaum txheej ntawm granite puag sib cais cais los ntawm txhua lwm yam, tsim pom cov khoob khoob, thiab tsis sib xws rau saum npoo. Qhov no tuaj yeem tshwm sim los ntawm kev ua ntawv sib raug zoo, thermal cycling, thiab machining yuam kev.
Kev daws: Kev kho thiab kho
Txoj kev sib raug zoo thiab kho cov txheej txheem koom nrog kev siv epoxy lossis polymer resins rau cov ntawv sau cov khoom hauv qab. Tom qab kev sib tham granite, kho chaw saum npoo yog tom qab ntawd rov ua av los kho cov tiaj tiaj thiab du. Cov ntawv cog lus granite yuav tsum tau kuaj xyuas rau ib qho seem uas muaj qhov khoob thiab cov hnab ris kom ntseeg tau tias lub hauv paus granite tau rov qab los ntawm nws lub zog qub.
Txhaum # 4: discoloration thiab staining
Qee zaum cov granite pib tuaj yeem txhim kho disololoration thiab staining cov teeb meem, xws li xim av thiab daj, thiab tsaus stains. Qhov no tuaj yeem tshwm sim los ntawm cov tshuaj nchuav thiab kev coj ua kom huv.
Kev daws: Kev tu thiab txij nkawm
Kev tsis tu ncua thiab kev tu kom zoo ntawm granite puag thaum paus tuaj yeem tiv thaiv kev sib txawv thiab staining. Kev siv nruab nrab lossis cov tshuaj ntxuav kom huv. Kev pom zoo kom pom zoo. Cov txheej txheem ntxuav yuav tsum ua raws li cov khw cov lus qhia kom tsis txhob ua rau muaj kev sib txawv granite. Yog tias muaj cov tawv ncauj ua haujlwm stubs, ib lub tsev huv huv granite yuav siv tau.
Hauv cov ntsiab lus, GRANITE POB yog ib cov khoom siv ruaj khov thiab txhim khu kev qha uas tau siv dav hauv cov khoom siv semiconductor. Txawm li cas los xij, nws tuaj yeem tsim kev ua txhaum lub sijhawm vim qhov ntsuas kub hloov pauv, cov khoom hnyav hnyav, thiab machining yuam kev. Nrog kev tu kom tsim nyog, tu, thiab kho, cov pob zeb granite tuaj yeem rov qab los, ua kom muaj txiaj ntsig zoo ntawm cov khoom siv semiconductor.
