MOPA laser tuaj yeem siv rau laser npav cov txheej txheem nrog cov xim sib txawv ntawm cov xim txho dub tob, tsis muaj kev puas tsuaj rau cov khoom saum npoo. Qhov tshwm sim tuaj yeem yog sib npaug rau cov annealing kos rau ntawm cov hlau, cov txiaj ntsig zoo ntawm kev kos cim tau tsim kom meej meej, uas yog yooj yim nyeem, tshwj xeeb tshaj yog nyob ntawm ntuj anodized txhuas.
Cov khoom haum rau laser ua ntawm AAO:
Cov tshuaj tiv thaiv anodic
Lub ntuj anodic alumina
Anodic alumina hauv txhua cov xim

Qhov zoo ntawm laser npav, kos ua thiab ua haujlwm ntawm AAO cov khoom
Tsis tsuas yog AAOcan raug kos (los ntawm kev tshem tawm cov txheej hluav taws xob), tab sis kuj nws tuaj yeem ua tiav los ua cov cim dub. Hauv tshwj xeeb, qhov cim hauv txhua theem xim txawv ntawm greyto tsaus dub tuaj yeem luam tawm ntawm AAO ntuj.
Kev tsom xam ntawm daim ntawv thov ntawm theAAO blackening rau sab tom qab ntawm cov xov tooj txawb
Lub xyoo pua 21st yog lub sijhawm ntawm hluav taws xob hluav taws xob, nyob rau hauv uas lub xov tooj ntawm tes tau ntsib ntau dua thiab ntau qhov kev cuam tshuam hauv peb lub neej niaj hnub, thiab tseem tab tom ua ib qho tseem ceeb hauv kev lag luam lub davhlau ya nyob twg. Qhov twg impliesthatmobile xov tooj yuav muaj muchbroadermarket qhia tawm yav tom ntej. Raws li cov kev hloov pauv tsis tu ncua, cov neeg siv khoom tau tso tawm ntau zuj zus mus rau kev lag luam xov tooj txawb kev lag luam uas ua rau ntau lub xov tooj ntse tau muaj cov txheej txheem nruj ntawm cov txheej txheem Logo ntawm lub cev plhaub, qhov twg Logos ntawm lub zog hloov cov khoom siv, lub mloog pob ntseg, thiab lub zog txawb cov tsev txhab nyiaj tag nrho cov cim nrog lub tshuab lasermarking ua tiav cov txiaj ntsig zoo tshaj plaws.
Cov khoom siv evolutionfor tus xov tooj ntawm tes
Thaum nyuam qhuav pib, feem ntau ntawm lub xov tooj txawb lub cev tau ua los ntawm cov khoom siv yas, feem ntau sib txuas lus, nrog rau LG-G series, Nokia (Lumia) thiab Samsung S5 qauv, txhua tus muaj mainstreamplasticshells, yog li pab txhawb rau kev ua tsis tiav xws li cov ntawv tsis zoo, tsis zoo cua sov dissipation, zoo li pheej yig, thiab xoob sib txuas ua ke thiab lwm yam. Ceramic cov ntaub ntawv tau dhau los ua lub hnub qub nyob hauv lub xov tooj txawb backplanein xyoo tsis ntev los no. Thaum lub Cuaj Hlis 2017, Xiaomi tso MIX2. Raws li kev tshawb fawb los ntawm kev ua lag luam los ntawm cov kws tshaj lij, cov khoom siv ceramic tau maj mam dhau los ua cov khoom sib tw rau cov neeg siv khoom siv hluav taws xob siab. Nws kwv yees tias xyoo 2018, kev lag luam sib faib rau cov xov tooj ntse ceramic backplane yuav ncav cuag 11.6 billion suav Yuan. Cov teeb meem kev tsim khoom xws li tus nqi siab tseem tsis tau ua rau ntau hom kev ua lag luam tseem tsis tau tiav. Tam sim no, cov qauv feem ntau ntawm kev ua lag luam txaus siab rau txhua lub cev aluminium, feem ntau yog txhuas cov khoom siv alloys uas feem ntau siv rau sab nraud ntawm cov xov tooj ntawm tes tom qab kev kho mob anodizingsurface, feem ntau hu ua anodized aluminium oxide.
Taw qhia ntawm AAOblackening
Muaj cov ntawv sau xim dub nyob rau sab nraum qab ntawm lub xov tooj nrog cov chaw tsim khoom' s LOGO thiab cov lej xov tooj uas zoo nkaus li zoo li cov uas luam tawm los ntawm mem hluav-dav hlau npav tshuab ntawm thawj nrawm. Tab sis qhov tseeb tsis yog number case, thiab tsis txhob lo lo ntxhuav luam ntawv, lawv ua tiav los ntawm lub tshuab laser npav, feem ntau hu ua blackened anodizingalumina. Cov txheej txheem ib txwm yog los kos cov ntawv lo lo ntxhuav ntawm qhov chaw ntawm cov ntawv ua haujlwm, thaum lub vijtsam luam ntawv hnyav hnyav, tsis zoo nkauj txaus, tsis yooj yim ua raws xim, vim li no cov nyhuv luam ntawv tsis zoo tagnrho, ntxiv mus, tus number case tsim ua ke rau screen luam ntawv muaj qee yam tshuaj lom neeg hnyav hlau. Tam sim no cov chaw tsim khoom siv cov cuab yeej hluav taws xob qis qis thiab kev tiv thaiv ib puag ncig technology uas yog lub tshuab laser npav. Nws tuaj yeem pab txhim kho qhov cuav los tiv thaiv kev muaj peev xwm, tab sis kuj nce tus nqi ntxiv, los ntawm kev ua cov khoom kom zoo dua nrog ntau lub hauv paus ntawm cov khoom lag luam.
AAO hais txog qhov tseeb ntawm cov ntawv txhuas thiab aluminium alloys yog txheej nrog tuab txheej ntawm aluminium oxide txhawm rau tiv thaiv oxidation ntxiv, uas muaj cov tshuaj lom neeg zoo ntawm Aluminium oxide. Anodizing tuaj yeem txhim kho qhov kev txhim kho corrosion tiv thaiv ntawm alloys alloys, nce qhov saum npoo nyuaj thiab hnav tsis kam ntawm alloys alloys, thiab txaus siab rau cov khoom zoo nkauj tom qab cov xim tsim nyog.
Lub tswv yim ntawm AAO blackening yog ntxiv rau oxidize anodized aluminium oxide txheej nrog zaj duab xis tuab ntawm 5-20μm thiab hloov cov kev ntxhib los mos ntawm cov khoom siv saum npoo nyob rau lub sijhawm luv luv los ntawm kev tsom rau cov kab teeb nrog lub zog siab laser. Lub hauv paus ntsiab lus ntawm aluminium blackening yog ua raws li cov nyhuv nanometer, becausethe kho laser tau ua rau oxide particle loj npaum li cas ntawm nanometer, cov khoom siv' s lub teeb pom kev ua kom muaj zog nce, yog li qhov pom lub teeb tsis cuam tshuam rau cov khoom yog nqus, nrog rau qhov tsis tshua pom lub teeb pom kev sab laug, kom nws zoo li dub hauv peb qhov muag pom qhov muag pom, yog li hu ua theAAOblackening .As rau qhov tuab ntawm txheej txheej oxide thiab txheej txheem txheej txheej txheej txheej ntawm AAO, feem ntau hais lus, nrog cov tuab ntawm 5um txog 20um, zaj duab xis tuab ncaj qha txiav txim siab qhov ua tau zoo thiab kev ua haujlwm ntawm blackening, feem ntau, nws yooj yim heev kom tsaus ntuj thaum zaj duab xis tuab yog nruab nrab ntawm 10um thiab 20um, yog hais tias zaj duab xis tuab tsawg dua 8um, ces cov oxide zaj duab xis yog nyias heev , uas yooj yim tawg thiab ua rau muaj qhov tshwm sim ntawm cov pob dawb, hauv qhov pom ntawm qhov no, cov ntsuas laser yog qhov xav tau rau kev them nyiaj. Txuas ntxiv, txheej txheem kev kho saum npoo ntawm AAO yuav cuam tshuam ncaj qha rau cov nyhuv blackening. txij li sandblasting thiab daim duab saum npoo yog qhov txheej txheem sib txawv, cov tuab ntawm sandblasting yuav muaj cov kev sib txawv ntawm cov cim nyhuv, uas txhais tau tias cov finer sandblasting hais yog, qhov zoo dua cov nyhuv blackening nyiam. Nws raug pom zoo tias zaj duab xis tuab ntawm lub anode txhuas yuav tsum yog 10-15μm, yog li cov nyhuv tag nrho cov xim dub tau zoo dua.
Cov ntawv thov ntawm laser lub cim ntawm cov cim lag luam dub, qauv, thiab cov ntawv sau rau saum npoo ntawm AAOhas tau siv dav thiab thaum ntxov siv los ntawm cov tuam txhab hluav taws xob xws li Apple, Huawei, ZTE, OPPO, VIVO, thiab lwm yam rau cov khoom lag luam hluav taws xob plhaub. Rau cov ntawv thov no, MOPA fiber lasers yog tam sim no ua tiav cov haujlwm. Vim tias MOPA laser muaj qhov ntau ntawm cov mem tes dav thiab cov mem tes zaus hloov kho, cov cim dub nyob rau saum npoo ntawm kev ua haujlwm ua haujlwm tuaj yeem pom tseeb pom zoo txais cov mem tes nqaim dav thiab lub siab zaus. Kuj ntau yam cuam tshuam ntawm graylevels tuaj yeem ua tiav los ntawm kev sib txuas sib txawv ntawm cov tsis muaj zog.
Nrog cov kev txhim kho tam sim no thiab cov kev xav tau ntawm kev ua lag luam, yav dhau los lo lo ntxhuav luam ntawv txheej txheem tau maj mam hloov los ntawm lub cim laser. Laser npav, raws li cov txheej txheem kev ua zauv tom qab, piv nrog cov txheej txheem kev ua ib txwm muaj xws li kev luam ntawv, kev txua tshuab, thiab hluav taws xob ua hluav taws xob, muaj qhov zoo tsis sib xws. Vim tias qhov zoo ntawm txij nkawm-dawb, siab hloov pauv thiab ntseeg siab, Laser npav tshuab yog tshwj xeeb tshaj yog tsim rau cov chaw uas muaj qhov siab xav tau kev ntsuas siab, qhov tob thiab du. Cov khoom siv hluav taws xob ntiag tug tau sawv cev los ntawm cov xov tooj ntawm tes tau hloov pauv thiab pab cov neeg' s lub neej, nrog kev nthuav dav ntawm kev ua haujlwm, kev ntse, thiab lub ntsej muag ntse. Raws li thev naus laus zis kev txhim kho ntawm microelectronics kev lag luam thiab cov neeg' s nrhiav kev siv lub xov tooj ntawm tus kheej, kev npliag laser npav ua thev naus laus zis yuav ua lub luag haujlwm tseem ceeb hauv kev tsim xov tooj txawb.
