Hauv cov khoom siv laser ceev ceev uas siv rau kev tsim cov chips thiab cov khoom ua kom raug, lub hauv paus granite zoo li qub yog qhov tseem ceeb rau kev zam cov teeb meem zais cia. Nws tuaj yeem daws cov "kev tua neeg raug" twg uas tsis pom? Hnub no, cia peb saib ua ke.
I. Tshem Tawm "Dab Ntxwg Nyoog ntawm Kev Co": Hais lus zoo rau kev cuam tshuam kev co
Thaum lub sijhawm txiav laser ceev ceev, lub taub hau laser txav mus ntau pua zaus hauv ib ob. Txawm tias qhov kev co me me tuaj yeem ua rau ntug txiav ntxhib. Lub hauv paus hlau zoo li "lub suab loj dua", ua kom cov kev co los ntawm kev ua haujlwm ntawm cov khoom siv thiab kev hla ntawm cov tsheb sab nraud. Qhov ceev ntawm lub hauv paus granite yog siab txog 3100kg / m³, thiab nws cov qauv sab hauv yog ntom li "cov pob zeb ua kom muaj zog", muaj peev xwm nqus tau ntau dua 90% ntawm lub zog co. Ib qho kev ntsuas tiag tiag ntawm qee lub tuam txhab optoelectronic pom tias tom qab hloov mus rau lub hauv paus granite, qhov roughness ntawm ntug ntawm cov silicon wafers txiav poob qis los ntawm Ra1.2μm mus rau 0.5μm, nrog rau qhov tseeb txhim kho ntau dua 50%.
Qhov thib ob, tiv taus "thermal deformation trap": Kub tsis ua rau muaj teeb meem ntxiv lawm
Thaum lub sijhawm ua laser, cov cua sov uas cov khoom siv tsim tawm tuaj yeem ua rau lub hauv paus nthuav dav thiab deform. Tus coefficient ntawm thermal expansion ntawm cov khoom siv hlau feem ntau yog ob npaug ntawm granite. Thaum qhov kub nce 10 ℃, lub hauv paus hlau tuaj yeem deform los ntawm 12μm, uas yog sib npaug rau 1/5 ntawm txoj kab uas hla ntawm tib neeg cov plaub hau! Granite muaj tus coefficient qis heev ntawm thermal expansion. Txawm tias nws ua haujlwm ntev, qhov deformation tuaj yeem tswj tau hauv 5μm. Qhov no zoo li muab "txhua yam kub tsis tu ncua" rau cov khoom siv kom ntseeg tau tias lub laser tsom mus rau qhov tseeb thiab tsis muaj qhov yuam kev.
Iii. Tsis txhob muaj "kev kub ntxhov hnav": Ntev lub neej ua haujlwm ntawm cov khoom siv
Lub taub hau laser txav mus los ceev ceev feem ntau los rau hauv kev sib cuag nrog lub hauv paus tshuab, thiab cov khoom tsis zoo yuav raug hnav dhau zoo li ntawv xuab zeb. Granite muaj qhov nyuaj ntawm 6 txog 7 ntawm Mohs nplai thiab tseem hnav-resistant dua li hlau. Tom qab siv li qub rau 10 xyoo, qhov hnav ntawm qhov chaw yog tsawg dua 1μm. Qhov sib piv, qee lub hauv paus hlau yuav tsum tau hloov txhua 2 txog 3 xyoos. Cov ntaub ntawv los ntawm ib lub Hoobkas semiconductor qhia tias tom qab siv cov hauv paus tshuab granite, tus nqi kho khoom siv tau txo qis los ntawm 300,000 yuan txhua xyoo.
Plaub, Tshem tawm "kev pheej hmoo ntawm kev teeb tsa": Ua tiav ib kauj ruam kom meej
Qhov tseeb ntawm cov txheej txheem ua haujlwm ntawm cov tshuab ib txwm muaj tsawg, thiab qhov yuam kev ntawm qhov chaw teeb tsa yuav ncav cuag ± 0.02 hli, ua rau cov khoom siv tsis sib xws zoo. Lub hauv paus granite ZHHIMG® yog ua los ntawm tsib-axis CNC, nrog qhov tseeb ntawm qhov chaw ntawm ± 0.01 hli. Ua ke nrog CAD / CAM prefabrication tsim, nws haum zoo li kev tsim kho nrog Lego thaum lub sijhawm teeb tsa. Ib lub koom haum tshawb fawb tau tshaj tawm tias lub sijhawm debugging ntawm cov khoom siv tau luv dua los ntawm 3 hnub mus rau 8 teev tom qab nws siv.
