Laser etching yog ib lub ntsiab lus dav uas suav nrog ntau yam kev cim thiab cov txheej txheem engraving ntiav. Nws yog siv rau ntau yam khoom, xws li cov khoom siv tsheb, cov khoom siv kho mob, cov thoob, cov khoom siv hluav taws xob microelectronic, thiab tombstones.
Laser etching yog ib txoj hauv kev tsim cov cim pom lossis cov qauv ntawm ntau yam ntaub ntawv. Qhov tseeb, lub ntsiab txhais ntawm "etching" (as opposed to marking or engraving) txawv nyob ntawm cov khoom thiab daim ntawv thov. Feem ntau, laser etching txawv ntawm kev kos npe; nws cuam tshuam qhov kev hloov ntawm qhov chaw contour ntawm ib feem, es tsis yog hloov cov xim saum npoo los yog kev ntxhib los mos. Txawm li cas los xij, qhov kev hloov pauv no hauv contour (uas tuaj yeem tsa los yog qhov chaw so) feem ntau yog ntiav ntau dua li cov kev hloov pauv los ntawm laser engraving.
Laser etching yog siv tib yam li ntau lwm yam cim, engraving, thiab txiav cov txheej txheem. Qhov tseeb, nws tsis yog qhov tsis yooj yim uas siv ib lub cuab yeej laser los ua tag nrho cov haujlwm no. Txhawm rau tsim cov qauv uas xav tau, lub laser beam raug tshuaj xyuas thoob plaws ntawm qhov chaw thaum raug hloov kho (hloov lub zog). Ib txoj hauv kev los tsim qhov kev txav no yog siv lub galvanometer scanning system. Nyob rau hauv rooj plaub no, lub beam txav yog ua tiav los ntawm kev txav ib daim iav. Txoj kev no feem ntau yog siv rau qhov me me vim qhov kev kub ceev. Tsis tas li ntawd, thev naus laus zis tuaj yeem ua qhov nkhaus nkhaus (feem ntau ua ke nrog kev sib hloov ntawm qhov chaw). Linear motion theem kuj tseem siv tau los txav cov nqaj xa khoom optics (los yog ib feem ntawm nws tus kheej) los piav txog cov cim cim. Qhov loj dua, xws li cov paib thiab cov monuments, yuav luag txhua zaus siv cov qauv no.
Qhov sib txawv ntawm cov khoom siv
Laser etching tuaj yeem ua rau yuav luag txhua yam khoom siv, suav nrog hlau, yas, iav, ceramics, pob zeb ntuj, thiab cov khoom siv semiconductor.
1.Laser etching ntawm hlau qhov chaw muaj nyob rau hauv ntau industries, xws li automotive, aerospace, kho mob, roj thiab roj, thiab lwm yam. Nws tuaj yeem siv rau yuav luag txhua yam hlau, xws li txhuas, hlau, tooj dag, tooj liab, thiab titanium.
Laser etching ntawm hlau feem ntau cuam tshuam cov khoom cua sov kom txog thaum nws yaj thiab nthuav me ntsis. Tom qab luv luv laser cua sov, cov khoom txias yuav luag tam sim ntawd. Nws resolidifies rau hauv ib cheeb tsam tsa nrog ib tug rougher kev ntxhib los mos dua ua ntej.
Rau cov hlau, laser etching feem ntau hloov qhov siab ntawm qhov chaw tsawg dua li ntawm 25 µm. Hauv qhov sib piv, laser engraving feem ntau hloov nws kaum zaus tob dua qhov no. Vim hais tias engraving cov cim ntxaum yuav tsum tshem tawm cov khoom siv ntau dua, laser etching feem ntau tuaj yeem ua tiav sai dua.
Lwm qhov zoo dua ntawm laser etching yog tias nws tuaj yeem tsim qhov tsaus, lub teeb, lossis txawm tias grey cim. Laser engraving feem ntau tsim tsuas yog cov cim tsaus. Txawm li cas los xij, lub teeb etched cov cim tsis zoo li ruaj thiab hnav-tiv taus li cov cim kos.
2. Laser-etched iav tuaj yeem siv rau kev kho kom zoo nkauj thiab kev lag luam. Cov ntawv nyeem, cov qauv tsim, thiab lwm cov qauv nyuaj, txawm tias cov duab, tuaj yeem kos rau ntawm iav haus, mugs, fwj, khoom plig, thiab iav. Hauv kev lag luam, ntau yam khoom (xws li dej haus lossis tshuaj, thiab lwm yam) yuav tsum tau ntim rau hauv cov thawv ntim iav, thiab cov ntaub ntawv xws li cov lej batch thiab txee lub neej tuaj yeem etched rau saum npoo ntawm cov thawv. Ib yam li ntawd, cov lej xov tooj thiab cov lej taug qab tuaj yeem raug etched ntawm iav substrates siv hauv microelectronics thiab kev tsim khoom.
Cov chaw laser-etched ntawm lub iav muaj qhov "frosted" nyhuv - semi-pob tshab es tsis yog pob tshab. Qhov no ua tiav los ntawm kev tshem tawm cov khoom me me (feem ntau tsawg dua 25 µm). Nws yog ib qho tsim nyog hais tias cov txheej txheem etching ua rau lub ntsej muag rougher.
Laser etching yog superior rau lwm yam txhua yam thiab tshuaj txoj kev vim nws yog ceev, huv si, thiab yooj yim adapts rau nkhaus nto (feem ntau nyob rau hauv wine iav thiab fwj).
3. Laser etching ntawm ntuj pob zeb (xws li granite los yog marble) yog dav siv rau tombstones, plaques thiab architectural lub hom phiaj. Zoo li iav etching, nws tseem tshem tawm tsuas yog cov txheej me me ntawm cov khoom thiab hloov qhov kev ntxhib los mos ntawm qhov chaw.
Laser etching yuav luag txhua zaus siv los ua cov cim teeb ntawm cov pob zeb tsaus. Cov qauv laser etching muaj ntau qhov me me nyob ze ua ke, ib yam li luam daim duab hauv ntawv xov xwm. Qhov no ua rau nws muaj peev xwm etch yuav luag txhua tus qauv, txawm tias cov cim grey.
Yog li ntawd, ntxiv rau cov ntawv nyeem, duab, kos duab thiab lwm yam qauv kuj tuaj yeem ua tau yooj yim etched. Laser etched pob zeb feem ntau ua rau pom qhov pom kev zoo dua li cov xuab zeb blasting lossis mechanical engraving. Laser etching tseem ceev dua li lwm txoj hauv kev.
4. Laser npav ntawm polymers muaj nyob rau hauv ntau yam kev lag luam, kev kho mob thiab cov khoom siv, nrog rau cov paib thiab cov khoom tshiab. Vim tias cov ntaub ntawv thiab cov txheej txheem koom nrog sib txawv heev, nws yog ib qho nyuaj rau kev txiav txim siab laser etching ntawm polymers thiab yuav ua li cas cov txheej txheem no txawv ntawm kev kos lossis kos duab. Cov txheej txheem siv "blistering" feem ntau, uas tawm ntawm lub teeb ci rau ntawm cov yas tsaus, yog qhov tseeb tias nws yog ib qho etch, vim nws tsuas yog ua rau me ntsis nyem (tsawg dua 50 µm).
Laser etching kuj tseem muaj nyob rau hauv semiconductor manufacturing thiab microelectronics ntau lawm vim hais tias nws muaj peev xwm tsim high-contrast marks nyob rau hauv polymers yam tsis tau qhia qhov tseem ceeb kub rau hauv ib feem. Piv txwv li, flip chips thiab lwm yam semiconductor ntim khoom tuaj yeem raug cim yam tsis muaj kev puas tsuaj rau lub voj voog uas lawv muaj.
Laser etching ntawm semiconductors lawv tus kheej yog siv thoob plaws hauv microelectronics manufacturing. Qhov no yog vim cov cim qhov tob tob (feem ntau yog 10 µm lossis tsawg dua) tsim cov cim zoo sib xws yam tsis ua rau muaj kev puas tsuaj rau ib puag ncig lossis hauv paus. Laser etching yog qhov tshwj xeeb zoo rau kev kos cov lej cim thiab lwm yam cim ntawm sab nraub qaum ntawm wafers. Nws kuj yog siv rau nyias pwm npog rau cov khoom ntim khoom.
Lasers rau Etching
Vim muaj ntau yam khoom siv thiab cov kev xav tau sib txawv, ntau hom lasers tau siv thaum etching.
| Fiber Lasers |
Fiber lasers feem ntau yog thawj qhov kev xaiv rau etching cov ntaub ntawv no vim hais tias lawv nyob ze-infrared tso zis zoo sib xws cov yam ntxwv haum ntawm feem ntau hlau. Lawv kuj tuaj yeem ua cov ceramics thiab qee cov polymers. Fiber lasers rau etching muab tib yam zoo nyob rau hauv lwm yam kev siv. Cov txiaj ntsig zoo no suav nrog tus nqi qis ntawm kev ua tswv cuab, kev ntseeg siab, lub neej ntev, zoo heev beam zoo, thiab yooj yim rau kev siv. |
| CO2 Lasers | CO2 lasers tso tawm deb infrared teeb, uas yog absorbed zoo los ntawm yuav luag tag nrho cov organic cov ntaub ntawv. Qhov no ua rau lawv zoo tagnrho rau etching ntoo thiab feem ntau polymers. CO2 lasers kuj feem ntau siv los ua pob zeb ntuj. |
| DPSS Lasers | Diode-pumped solid-state lasers tuaj yeem xa cov khoom siv hluav taws xob siab hauv lub teeb ntsuab lossis ultraviolet nrog cov nqaj zoo heev. Qhov no ua rau lawv zoo tagnrho rau ob hom kev siv etching. Thawj yog rau cov ntaub ntawv uas tsis nqus ntev wavelengths zoo. Qhov no yog qhov teeb meem nrog qee cov polymers. Daim ntawv thov thib ob suav nrog cov ntaub ntawv nyias lossis cov khoom kub-rhiab. Feem ntau cov ntaub ntawv feem ntau muaj peev xwm nqus tau siab rau luv wavelengths, tshwj xeeb tshaj yog ultraviolet lub teeb, uas txhais tau hais tias lub teeb laser yog absorbed tag nrho ntawm qhov tob tob. Qhov tshwm sim yog tsawg cua sov ntawm thaj chaw ib puag ncig. Vim li no, DPSS laser etching yog siv thoob plaws hauv semiconductor manufacturing thiab ntim, lwm yam khoom siv hluav taws xob, khoom kho mob, thiab cov ntxaij vab tshaus. |
| Semiconductor Lasers | Semiconductor lasers muaj qhov dav wavelength ntau yam, los ntawm xiav mus rau ze infrared, ua rau lawv muaj peev xwm etching ntau yam hlau thiab tsis yog hlau. Kev sib xyaw tshwj xeeb ntawm cov nqaj zoo thiab tus nqi ntawm cov lasers no ua rau lawv zoo tagnrho rau cov khoom siv hluav taws xob pheej yig, feem ntau rau cov khw muag khoom me me, cov quav hniav thiab cov khoom plig, thiab cov neeg nyiam ua haujlwm. |
