Nyob rau hauv lub precision laboratory rau manufacturing chips, muaj ib tug seemingly unremarkable "tom qab-the-scenes hero" - lub granite tshuab puag. Tsis txhob underestimate lub pob zeb no. Nws yog tus yuam sij kom ntseeg tau qhov tseeb ntawm kev sim tsis muaj kev puas tsuaj ntawm wafers! Niaj hnub no, cia peb saib yuav ua li cas nws khaws cov cuab yeej tshawb nrhiav ib txwm "kab rov tav thiab ntsug".
1. Yug los nrog "cov noob ruaj khov"
Granite tsis yog pob zeb zoo tib yam. Nws cov qauv sab hauv yog zoo li lub kaw ntom nti "mineral jigsaw puzzle". Quartz, feldspar thiab lwm yam siv lead ua zoo sib xws, nrog kev ceev ceev heev thiab yuav luag tsis muaj voids. Qhov no zoo ib yam li kev tsim lub tsev nrog cov pob zeb uas muaj zog, uas yog ob qho tib si ruaj khov thiab ruaj khov. Thaum cov cuab yeej tshuaj xyuas "tso" rau ntawm nws, txawm tias nws hnyav ob peb tons, qhov deformation ntawm granite puag yog negligible, tsuas yog ib feem kaum ntawm cov hlau!
Txawm ntau impressive yog tias nws yuav luag tsis ntshai ntawm qhov kub thiab txias hloov. Cov khoom siv hlau zoo ib yam yuav "nthuav thiab nce qhov hnyav" thaum rhuab thiab "daim ntawv cog lus thiab ua thinner" thaum txias. Txawm li cas los xij, granite zoo li muaj "qhov kub tsis tu ncua". Thaum qhov kub thiab txias hloov ntawm 1 ℃, nws qhov nthuav dav thiab kev cog lus tsuas yog ib txhiab ntawm tib neeg cov plaub hau xwb. Nws yuav tsum raug sau tseg tias txawm tias muaj kev hloov pauv me ntsis ntawm qhov ntsuas kub ntawm qhov ntsuas, lub hauv paus granite tuaj yeem ruaj khov rau cov khoom siv thiab tiv thaiv qhov theem ntawm "deviating".
Thib ob, cov txheej txheem ua haujlwm ntawm "devilish cov ntsiab lus"
Ua kom lub hauv paus granite zoo dua, engineers ua haujlwm "dub technology" rau kev ua haujlwm. Xav txog cov pob zeb polishing nrog "super sandpaper" ua los ntawm pob zeb diamond - qhov no yog li cas lub tshuab tsib-axis sib tsoo ua haujlwm. Nws yuav zom qhov saum npoo ntawm granite kom zoo dua li daim iav hauv peb kauj ruam:
Kev sib tsoo ntxhib: Ua ntej, tshem tawm cov pob zeb saum npoo av thiab tswj lub tiaj tus mus rau ib-ntu ntawm tib neeg cov plaub hau.
Semi-fine sib tsoo: Ntxiv kev ua kom zoo dua, nrog rau qhov flatness nce mus rau ib-tsib tsib caug ntawm tib neeg cov plaub hau.
Kev sib tsoo zoo: Thaum kawg, nws yog polished nrog ultra-fine sib tsoo hmoov, ua tiav qhov flatness ntawm ib txhiab ntawm tib neeg cov plaub hau! Nyob rau ntawm lub sijhawm no, qhov saum npoo ntawm lub hauv paus granite yog zoo li "kab rov tav theem" tailor-made rau cov khoom soj ntsuam.
Qee qhov high-end mounts kuj muaj "ntse hlwb" - cov qib high-precision ua tau zoo li "tus neeg saib xyuas me me" ntawm lub luag haujlwm 24 teev hauv ib hnub. Thaum nws pom tias cov cuab yeej tilted los ntawm 0.01 degrees (lub kaum sab xis me dua li ntawm tus cwj mem), lub tshuab hydraulic yuav qhib tam sim ntawd thiab "txoj kev ncaj" cov cuab yeej hauv 30 vib nas this.
Thib peb, ingenious tsim ntxiv txhim khu kev ruaj ntseg
Cov engineers kuj racked lawv lub hlwb ntawm cov qauv ntawm lub tshuab puag. Hauv qab yog ua rau hauv cov duab hexagonal honeycomb, ib yam li tus muv lub Hive, uas tsis tsuas yog txo qhov hnyav, tab sis kuj sib npaug faib lub siab. Thaum qhov kev soj ntsuam xyuas txav ntawm lub wafer, qhov deformation ntawm txhua qhov chaw ntawm lub hauv paus yog yuav luag tib yam, kom ntseeg tau tias cov kab rov tav siv nyob ruaj khov txhua lub sijhawm.
Qhov zoo tshaj plaws yog qhov "tsis pom kev poob siab" - lub piezoelectric ceramic shock absorber - yog ntsia nruab nrab ntawm lub hauv paus thiab hauv av. Nws tuaj yeem ntes ntau yam kev vibrations xws li 1 txog 1000Hz zoo li lub radar thiab tam sim ntawd emit reverse nthwv dej rau "tawm" qhov cuam tshuam. Piv txwv li, kev vibrations uas tsim los ntawm kev ua haujlwm ntawm cov tshuab tom ntej los yog cov tsheb thauj neeg uas hla sab nraud yog txhua yam "tsis muaj txiaj ntsig" nyob rau hauv pem hauv ntej ntawm nws.
Cov ntaub ntawv hais lus rau nws tus kheej: Lub Hwj Chim Zoo Li Cas?
Hauv kev siv tswv yim, kev ua tau zoo ntawm granite puag yog qhov xav tsis thoob:
Kev tshuaj xyuas qhov muag: Qhov tseeb ntawm kev txheeb xyuas qhov tsis xws luag ntawm wafers tau raug txhim kho los ntawm 3 microns mus rau 1 micron (1 micron = ib-sixtieth ntawm tib neeg cov plaub hau).
Kev kuaj ultrasonic: Qhov yuam kev hauv kev ntsuas wafer thickness tau raug txo los ntawm peb lub hlis twg.
Kev siv lub sijhawm ntev: Tom qab ua haujlwm tas mus li rau ib xyoos, qhov kev hloov pauv hauv qib yuav luag tsis pom zoo, thaum lub hauv paus tshuab zoo tib yam tau ntev dhau los ua "hunched dua".
Los ntawm qhov zoo ntawm cov ntaub ntawv ntuj rau kev ua tiav thiab kev tsim kho tshiab, lub hauv paus granite tau ua pov thawj nrog nws "lub zog" tias yog tias koj xav kom raug txheeb xyuas cov chips, lub pob zeb no yog qhov tseem ceeb tiag tiag!
