Kwicandelo le-semiconductor wafer grooving, ukuchaneka yindlela yokuphila. Isiseko se-granite esingaqhelekanga sinokubangela ukutsiba okuphezulu ekusebenzeni kwezixhobo ze-grooving! Ngawaphi "amandla amakhulu" esiwafihlayo? Kutheni kusithiwa ukukhetha isiseko se-granite esifanelekileyo kuthetha ukuba uphumelele phakathi? Namhlanje, siza kukubonisa ngokunzulu!
I. Amandla Emvelo: "Iingenelo Ezithathu Ezingokwemvelo" zeGranite
Ukumelana nokunyikima komhlaba kuzinzile njengeNtaba iTai
I-granite inobunzima obufikelela kwi-2,800-3,100 kg/m³, kwaye isakhiwo sayo sixinene njenge "nqaba yelitye". Kwimeko yokungcangcazela rhoqo kwe-wafer grooving (i-grooves yezixhobo idlula amaxesha ali-100 ngomzuzu), inokufunxa amandla angaphezu kwama-90% okungcangcazela, njengokuxhobisa izixhobo "ngeteknoloji emnyama efunxa ukothuka"! Idatha elinganisiweyo evela kumzi-mveliso othile weetshiphusi ibonisa ukuba emva kokusebenzisa isiseko se-granite, ubukhulu be-jitter yentloko ye-grooving cutter bunciphile ukusuka kwi-15μm ukuya kwi-3μm, kwaye imiphetho yee-micro-grooves eziqoshiweyo ithambile njengesipili.
2. "Umzimba omelana nobushushu" Awunaloyiko lomahluko kubushushu
Izinto eziqhelekileyo "ziyakhula kwaye ziguquguquke" xa zishushu kwaye "ziyacotha kwaye ziguquguquke" xa zipholile, kodwa i-coefficient yokwandiswa kobushushu begranite iphantsi njenge-4-8×10⁻⁶/℃, eyi-1/5 kuphela yeyoweentsimbi! Nokuba ubushushu kwindawo yokusebenzela butshintsha ngokukhawuleza nge-10℃ kwiiyure ezingama-24, ukuguquguquka kwayo kungaphantsi kwe-0.01mm kwaye phantse kungahoywa. Oku kuthetha ukuba nokuba kukho utshintsho lwemini nobusuku okanye ukusebenza ixesha elide kunye nokuveliswa kobushushu kwezixhobo, isiseko segranite sinokugcina indawo yeslothi "ingashukumi" ngalo lonke ixesha.
3. Ukumelana nokuguguleka okungapheliyo
Ubunzima be-Mohs be-granite bufikelela kwi-6 ukuya kwi-7, obufana nobe-quartz stone, kwaye ukumelana kwayo nokuguguleka kuphindwe kathathu kunokwentsimbi eqhelekileyo! Phantsi kokungqubana kwexesha elide kwe-wafer grooving, umphezulu wesiseko awugugi. Emva kokuba i-foundry ethile isebenzise iziseko ze-granite kangangeminyaka emihlanu, ukuguguleka kwahlala kungaphakathi kwe-±0.5μm/m xa kuhlolwa, kwaye ukuchaneka kwe-grooving kwahlala kungaguquki, okusindisa inani elikhulu leendleko zokulinganisa izixhobo kunye nokutshintsha.
Ii. Uhlengahlengiso Oluchanekileyo: I-Granite ihlangabezana njani neemfuno ezahlukeneyo zokugrumba?
Isiqendu 1: Ukugrumba okucolekileyo kakhulu (ii-micro-grooves ezingaphantsi kwe-10μm)
Imfuneko: Ubukhulu obupheleleyo
Iingenelo zegranite: Ngokusebenzisa ukucubungula okuchanekileyo kwe-axis ezintlanu, ubucaba bunokulawulwa ngaphakathi kwe-±0.5μm/m, oko kuthetha ukuba kubude bemitha e-1, impazamo yokuphakama incinci ngokuphindwe ka-200 kuneenwele zomntu! Qinisekisa ukuba umgama phakathi kwentloko yokusika i-grooving kunye ne-wafer uhlala uchanekile, kwaye impazamo yobubanzi bee-micro-grooves eziqingqiweyo ayidluli kwi-±0.1μm.
Isiqendu sesi-2: Ukuveliswa kwemveliso enkulu ngesantya esiphezulu
Imfuneko: Ukusebenza kakuhle kokufunxwa komothuko
Iingenelo zegranite: Iimpawu zayo zendalo zokufunxa ngaphakathi zinokunciphisa ngokukhawuleza ukungcangcazela kwezixhobo. Emva kokuba umzi-mveliso othile wephaneli uqalise iziseko zegranite, isantya sokugungqa sanda ngama-40%, kwaye izinga lemveliso lanyuka ukusuka kuma-85% ukuya kuma-96%, nto leyo efezekisa isivuno esiphindwe kabini sokusebenza kakuhle kwemveliso kunye nomgangatho!
Isiqendu 3: Ukulungiswa kweNdalo okuntsonkothileyo (Ubushushu obuphezulu/ukugqwala)
Iimfuno: Ukumelana nobushushu obuphezulu kunye nokumelana nokugqwala
Iingenelo zegranite: Uzinzo oluqinileyo lweekhemikhali, olumelana nokugqwala kwe-asidi kunye ne-alkali; Ine-coefficient ephantsi yokwanda kobushushu kwaye ayizukuguquguquka nokuba kubushushu obuphezulu bendawo (150℃) ngexesha lokugaya nge-laser. Isiseko segranite esisetyenziswa kwilabhoratri ethile enesisombululo sokugaya nge-corrosive besisoloko sisetyenziswa kangangeminyaka emithathu, kwaye umphezulu wesiseko uhlala ungaguquki.
Iii. Ungayikhetha njani isiseko seGranite "esisemgangathweni ophezulu"?
Jonga uxinano: I-Granite enoxinano lwe-≥2800kg/m³ inesakhiwo esincinci ngakumbi.
Jonga iziqinisekiso: Qinisekisa ukuba uyaziqaphela iziqinisekiso ezisemthethweni ezifana ne-ISO 9001 kunye ne-CNAS ukuqinisekisa umgangatho.
Idatha yokuqinisekisa: Umenzi kufuneka anike iingxelo zovavanyo malunga ne-coefficient yokwandiswa kobushushu (< 8×10⁻⁶/℃) kunye nokuthamba (± 0.5μm/m).
Uvavanyo olukwindawo: Cofa isiseko. Isandi esicacileyo sibonisa ukuba akukho mifantu ngaphakathi. Ukuba umphezulu wokuchukumisa uthambile njengesipili, oko kubonisa ukuchaneka okuphezulu kokucubungula.
Isiphelo: Khetha i-granite efanelekileyo kwaye uphumelele isiqingatha semfazwe kwi-grooving!
Ukususela ekuchaseni ukutsha, ekuchaseni ubushushu ukuya ekuchaseni ukuguguleka, isiseko segranite, "nobuhle bendalo" kunye "namandla aqinileyo", siye saba liqabane legolide lezixhobo zokugoqa iiwafer. Kule mihla yokuvelisa i-semiconductor elandela ukuchaneka kwe-nanoscale, isiseko segranite esisemgangathweni ophezulu asikokutyala imali kwizixhobo kuphela kodwa sikwasisiqinisekiso sexesha elide sokusebenza kakuhle kwemveliso kunye nomgangatho wemveliso!
