Rau daim ntawv thov ntawm ultrafast laser nyob rau hauv precision machining ntawm cov neeg siv khoom electronics kev lag luam

Nrog txoj kev loj hlob sai ntawm kev lag luam thoob ntiaj teb cov neeg siv khoom siv hluav taws xob, cov khoom siv hluav taws xob siv hluav taws xob tau hloov kho mus rau kev sib koom ua ke siab thiab siab precision.Cov khoom siv sab hauv ntawm cov khoom siv hluav taws xob tau dhau los ua me thiab me, thiab cov kev xav tau rau kev ua kom zoo thiab kev sib koom ua ke hauv hluav taws xob tau dhau los ua ntau dua.Txoj kev loj hlob ntawm advanced laser manufacturing technology tau coj cov kev daws teeb meem rau precision ua kev xav tau ntawm hluav taws xob kev lag luam.Ua cov txheej txheem ntawm cov xov tooj ntawm tes ua piv txwv, laser ua tshuab tau nkag mus rau hauv kev tshuaj ntsuam txiav, lub koob yees duab lens txiav, logo cim, sab hauv cov khoom siv vuam thiab lwm yam kev siv.Nyob rau ntawm "2019 Seminar ntawm daim ntawv thov ntawm laser advanced manufacturing technology nyob rau hauv kev lag luam", cov kws tshawb fawb thiab kev txawj ntse los ntawm Tsinghua University thiab Shanghai lub koom haum ntawm Optics thiab mechanics ntawm Suav Academy ntawm Sciences ua ib tug in-deb sib tham nyob rau hauv-tob txog daim ntawv thov tam sim no. laser advanced manufacturing nyob rau hauv precision ua cov khoom siv hluav taws xob.

Tam sim no cia kuv coj koj los txheeb xyuas rau 6 daim ntawv thov ntawm ultrafast laser hauv kev ua tiav ntawm cov neeg siv khoom siv hluav taws xob kev lag luam:
1.Ultra ceev laser ultra-nplua tshwj xeeb raug: ultra ceev laser micro nano ua yog ib qho ultra-fine tshwj xeeb tsim tshuab, uas tuaj yeem ua cov ntaub ntawv tshwj xeeb kom ua tiav cov qauv tshwj xeeb thiab tshwj xeeb kho qhov muag, hluav taws xob, tshuab thiab lwm yam khoom.Txawm hais tias lub tshuab no tsis tuaj yeem tso siab rau cov khoom siv los ua cov cuab yeej, nws nthuav dav cov ntaub ntawv ua tiav, thiab muaj qhov zoo ntawm tsis hnav thiab deformation.Nyob rau tib lub sijhawm, tseem muaj cov teeb meem uas yuav tsum tau daws thiab txhim kho, xws li kev xa khoom hluav taws xob thiab kev siv hluav taws xob, laser fais fab thiab kev nqus wavelength xaiv, spatial qhov tseeb ntawm kev xa khoom, kev tsim qauv, kev ua haujlwm zoo thiab raug."Xib fwb sunhongbo ntawm Tsinghua University ntseeg hais tias laser manufacturing yog tseem dominated los ntawm tshwj xeeb cov cuab yeej, thiab macro thiab micro nano manufacturing ua lawv lub luag hauj lwm. Cov khoom siv kho qhov muag thiab cov qauv hloov pauv, quantum chips thiab nano robots. Lub neej yav tom ntej txoj kev loj hlob ntawm ultrafast laser manufacturing yuav yog high-tech, siab ntxiv cov khoom, thiab siv zog mus nrhiav ib tug breakthrough nyob rau hauv kev lag luam. "
2.Houndred watt ultrafast fiber ntau lasers thiab lawv daim ntaub ntawv: nyob rau hauv xyoo tas los no, ultrafast fiber lasers tau lug siv nyob rau hauv cov neeg siv khoom electronics, tshiab zog, semiconductors, kev kho mob thiab lwm yam teb nrog lawv cov cim ua los.Nws suav nrog daim ntawv thov ntawm ultrafast fiber ntau laser nyob rau hauv zoo micromachining teb xws li saj zawg zog Circuit Court board, OLED zaub, PCB board, anisotropic txiav ntawm lub xov tooj txawb screen, thiab lwm yam.Nws yog kwv yees tias tag nrho cov lag luam ntim ntawm ultrafast laser yuav ntau tshaj 2 billion US dollars los ntawm 2020. Tam sim no, lub ntsiab ntawm lub lag luam yog ultrafast solid-state lasers, tab sis nrog rau kev nce ntawm lub zog mem tes ntawm ultrafast fiber lasers, qhov sib koom ntawm ultrafast fiber ntau lasers yuav nce ntau.Qhov tshwm sim ntawm qhov nruab nrab lub zog siab ultrafast fiber ntau lasers ntau dua 150 W yuav ua kom lub lag luam nthuav dav ntawm ultrafast lasers, thiab 1000 W thiab MJ femtosecond lasers yuav maj mam nkag mus rau hauv kev ua lag luam.
3.Qhov kev thov ntawm ultrafast laser hauv iav ua: kev txhim kho ntawm 5g thev naus laus zis thiab kev loj hlob sai ntawm cov davhlau ya nyob twg xav tau txhawb kev txhim kho cov khoom siv hluav taws xob semiconductor thiab ntim tshuab, thiab muab cov kev xav tau siab dua rau kev ua haujlwm ntawm iav thiab qhov tseeb.Ultrafast laser ua tshuab tuaj yeem daws cov teeb meem saum toj no thiab dhau los ua kev xaiv zoo rau kev ua iav hauv 5g era.
4.Application ntawm laser precision txiav hauv kev lag luam hauv hluav taws xob: kev ua haujlwm siab fiber ntau laser tuaj yeem nqa tawm high-speed thiab high-precision laser txiav, drilling thiab lwm yam laser micro machining raws li cov qauv tsim duab ntawm precision nyias-walled hlau sib npaug ntawm txoj kab uas hla thiab tshwj xeeb-zoo li tus yeeb nkab, raws li zoo raws li precision dav hlau txiav ntawm me me hom.Cov tom kawg yog cov khoom siv high-speed thiab high-precision laser micromachining khoom tshwj xeeb hauv precision dav hlau nyias-walled instruments, uas tuaj yeem ua cov hlau tsis muaj steel, aluminium alloy, tooj liab alloy, tungsten, molybdenum, lithium, magnesium aluminium alloy, ceramics thiab lwm yam khoom siv dav hlau. feem ntau siv nyob rau hauv lub teb ntawm electronics instruments.
5.Application ntawm ultrafast laser nyob rau hauv cov txheej txheem ntawm tshwj xeeb-zoo li tus screen: iphonex tau qhib ib tug tshiab qauv ntawm kev qhia tshwj xeeb-zoo li tus screen, thiab kuj txhawb kev nruam kev kawm thiab kev loj hlob ntawm tshwj xeeb-zoo li tus screen txiav tshuab.Zhu Jian, tus thawj coj ntawm Han lub zeem muag laser thiab semiconductor ua lag luam department, qhia Han tus kheej tsim icicles diffraction dawb beam technology.Cov thev naus laus zis tau txais cov txheej txheem kho qhov muag qub, uas tuaj yeem ua rau lub zog sib npaug sib npaug thiab ua kom muaj qhov zoo sib xws ntawm ntu txiav;Txais yuav tsis siv neeg splitting tswvyim;Tom qab lub vijtsam LCD raug txiav, tsis muaj qhov cuam tshuam rau ntawm qhov chaw, thiab qhov raug txiav yog siab (<20 μ m) Cov nyhuv kub qis (<50 μ m) Thiab lwm yam zoo.Cov tshuab no yog tsim rau kev ua cov iav iav, nyias iav txiav, LCD npo drilling, tsheb iav txiav thiab lwm yam.
6.Technology thiab daim ntawv thov ntawm laser luam ntawv conductive circuits rau saum npoo ntawm cov ntaub ntawv ceramic: cov ntaub ntawv ceramic muaj ntau yam zoo, xws li thermal conductivity, tsis tshua muaj dielectric, muaj zog txhua yam khoom, zoo rwb thaiv tsev kev ua tau zoo thiab lwm yam.Lawv tau maj mam tsim mus rau hauv ib qho zoo tagnrho ntim substrate rau lub cim tshiab ntawm kev sib xyaw circuits, semiconductor module circuits thiab fais fab hluav taws xob modules.Ceramic circuit board ntim tshuab kuj tau muaj kev txhawj xeeb thiab tsim sai heev.Cov khoom siv hluav taws xob hluav taws xob uas twb muaj lawm tam sim no muaj qee qhov tsis txaus, xws li cov khoom siv kim, lub voj voog ntev ntau lawm, tsis txaus versatility ntawm substrate, uas txwv txoj kev loj hlob ntawm lwm yam technologies thiab cov khoom siv.Yog li ntawd, txoj kev loj hlob ntawm ceramic circuit board manufacturing technology thiab cov cuab yeej muaj kev ywj pheej kev txawj ntse txoj cai yog qhov tseem ceeb los txhim kho Tuam Tshoj txoj kev theem thiab kev sib tw tseem ceeb hauv kev tsim hluav taws xob.
