Chifukwa chiyani granite "imalamulira" zida zolondola? Makhalidwe asanu akuluakulu kuposa zida zachikhalidwe.

M'madera monga kupanga chip ndi kuyeza kolondola, katundu wa zipangizo amatsimikizira kulondola kwa zipangizo. Granite, yokhala ndi zikhalidwe zisanu zazikuluzikulu, imadziwika ndi zinthu monga zitsulo, mapulasitiki opangira uinjiniya ndi zoumba, ndipo yakhala "mnzake wagolide" wa zida zapamwamba.

1. Kukhazikika kwamafuta: "chitetezo" cha kusinthasintha kwa Kutentha
Pakusintha kulikonse kwa kutentha kwa 1 ℃, chitsulo chosapanga dzimbiri chimakula ndi 17μm/m, aloyi ya aluminiyamu imakula ndi 23μm/m, pomwe granite imangokulira ndi 4-8μm/m. M'mafakitale a semiconductor, kutentha kwakukulu komwe kumapangidwa ndi makina a photolithography kapena kusiyana kwa kutentha pakati pa kuyambika ndi kuyimitsidwa kwa ma air conditioners kumakhala ndi zotsatira zochepa pa kukula kwa granite. Mosiyana ndi izi, kusinthika kwazitsulo ndi mapulasitiki chifukwa cha kuwonjezereka kwa kutentha ndi kutsika kungayambitse kusalinganika bwino kwa zigawo zolondola.

2. Kukana kugwedezeka: "Wowononga" wa mphamvu yogwedezeka
Granite ili ndi kachulukidwe kwambiri (2.6-3.1g/cm³), kuuma kwa 6-7 pa sikelo ya Mohs, ndi chiŵerengero chonyowa 5-10 kuposa chitsulo chosapanga dzimbiri. Pazida zoyezera mwatsatanetsatane, zimatha kutsitsa 90% ya mphamvu yakugwedezeka mkati mwa masekondi 0.5, pomwe zida zachitsulo zimafunikira masekondi atatu mpaka 5. Kugwedezeka komwe kumapangidwa ndi ntchito ya zipangizo ndi kayendetsedwe ka ogwira ntchito pamsonkhanowu ndizovuta kugwedeza kukhazikika kwa zipangizo zothandizidwa ndi granite.

3. Kukhazikika kwa Chemical: "ouma khosi" m'malo acidic ndi amchere
Pamene granite yaviikidwa mu asidi amphamvu (pH = 2) kapena alkali wamphamvu (pH = 12) kwa maola 1000, kuchuluka kwa dzimbiri pamwamba kumakhala kosakwana 0.01μm. Chitsulo chosapanga dzimbiri chimakhala ndi dzimbiri chifukwa cha ma acid ndi alkalis, aloyi ya aluminiyamu imawopa zinthu zamchere, ndipo mapulasitiki a engineering amatupa akakumana ndi zosungunulira za organic. Mapangidwe a granite (porosity <0.1%) amathanso kuteteza kuipitsidwa kwa tinthu, ndikupangitsa kukhala "chinthu chosankhidwa" cha zipinda zoyeretsera za semiconductor.

4. Kukonzekera ndi Mtengo: "Master of Balance" pakati pa Precision and Cost Performance
Granite imatha kukhala yosalala ya ≤0.5μm/m ndi roughness pamwamba Ra ya ≤0.05μm, koma kukonza kumatenga nthawi yayitali. Chitsulo chosapanga dzimbiri ndi chosavuta kuchipanga koma chimakhala chopindika, pomwe zoumba zake zimakhala zolondola kwambiri koma ndizokwera mtengo. Muzochitika zomwe zimatsata kulondola kwa nanoscale, mtengo wamtengo wapatali wa granite umaposa kwambiri zida zina.

5. Electromagnetic Purity: "Woyeretsa" wa Zida Zamagetsi
Monga zinthu zopanda zitsulo, granite ndi yopanda maginito komanso yosayendetsa, ndipo sichidzasokoneza masensa ndi zipangizo zamagetsi. Mayendedwe amagetsi ndi maginito azitsulo, magetsi osasunthika a mapulasitiki a engineering, ndi kutayika kwa dielectric kwa ceramics zonse zimakhala "zofooka" pamaso pa zida zolondola monga makina a photolithography ndi makina a nyukiliya maginito a resonance. Komabe, granite ndiyoyenera kwambiri kumadera okhudzidwa ndi ma elekitiroma.

Kuchokera kukana kutentha kwambiri mpaka kukaniza kugwedezeka, kuchokera pakupewa dzimbiri mpaka kusokonezedwa ndi zero maginito amagetsi, granite yatsimikizira ndi zinthu zake zolimba kuti pakupanga mwatsatanetsatane, ndi "mfumu" yosasinthika.
