Nyob rau hauv lub nthwv dej ntawm LED kev lag luam hloov mus rau LED thev naus laus zis, qhov tseeb ntawm cov khoom siv sib txuas ncaj qha txiav txim siab cov txiaj ntsig ntawm cov ntim ntim thiab cov khoom lag luam. ZHHIMG, nrog nws txoj kev sib sib zog nqus ntawm cov ntaub ntawv kev tshawb fawb thiab kev tsim khoom, muab kev txhawb nqa tseem ceeb rau cov khoom siv LED tuag thiab tau dhau los ua ib qho tseem ceeb ntawm kev tsav tsheb thev naus laus zis hauv kev lag luam.
Ultra-siab rigidity thiab stability: xyuas kom meej micron-theem tuag bonding raug
Cov txheej txheem kev tuag ntawm cov leds yuav tsum muaj kev sib raug zoo ntawm micron-loj chips (nrog rau qhov me me tshaj li 50μm × 50μm) mus rau hauv lub substrate. Txhua qhov deformation ntawm lub hauv paus tuaj yeem ua rau tuag bonding hloov. Qhov ceev ntawm ZHHIMG cov khoom ncav cuag 2.7-3.1g / cm³, thiab nws compressive zog tshaj 200MPa. Thaum lub sijhawm ua haujlwm ntawm cov cuab yeej siv, nws tuaj yeem tiv taus qhov kev co thiab kev poob siab uas tsim los ntawm kev txav siab ntawm lub taub hau tuag (txog 2000 zaug hauv ib feeb). Kev ntsuas qhov tseeb ntawm lub tuam txhab ua lag luam LED qhia tau hais tias cov khoom siv sib txuas tuag siv ZHHIMG lub hauv paus tuaj yeem tswj cov nti offset nyob rau hauv ± 15μm, uas yog 40% siab dua li cov khoom siv hauv paus thiab ua tau raws li cov kev cai nruj ntawm JEDEC J-STD-020D tus qauv rau kev sib raug zoo tuag.
Qhov zoo tshaj plaws thermal stability: Hais txog qhov kev sib tw ntawm cov khoom siv kub nce
Lub sijhawm ua haujlwm ntev ntawm cov khoom siv sib khi tuaj yeem ua rau qhov kub thiab txias (txog li 50 ℃), thiab thermal expansion ntawm cov khoom siv sib txawv tuaj yeem hloov qhov chaw txheeb ze ntawm lub taub hau tuag thiab lub substrate. Lub coefficient ntawm thermal expansion ntawm ZHHIMG yog tsawg li (4-8) × 10⁻⁶ / ℃, uas tsuas yog ib nrab ntawm cam khwb cia hlau. Thaum lub sij hawm tas mus li 8-teev kev ua haujlwm siab, qhov hloov pauv ntawm ZHHIMG lub hauv paus yog tsawg dua 0.1μm, ua kom muaj kev tswj xyuas meej ntawm kev sib txuas ntawm lub siab thiab qhov siab kom tiv thaiv kev puas tsuaj los yog cov hlau tsis zoo los ntawm thermal deformation. Cov ntaub ntawv los ntawm Taiwanese LED ntim Hoobkas qhia tau hais tias tom qab siv ZHHIMG lub hauv paus, kev tuag kev sib raug zoo tus nqi poob los ntawm 3.2% mus rau 1.1%, txuag tshaj 10 lab yuan hauv cov nqi txhua xyoo.
Cov yam ntxwv siab damping: tshem tawm kev cuam tshuam kev co
Lub 20-50Hz vibration generated los ntawm high-speed txav ntawm lub taub hau tuag, yog tias tsis attenuated nyob rau hauv lub sij hawm, yuav cuam tshuam rau qhov chaw tso kawm ntawm cov nti. Lub sab hauv siv lead ua qauv ntawm ZHHIMG endows nws nrog zoo damping kev ua tau zoo, nrog ib tug damping piv ntawm 0.05 mus rau 0.1, uas yog 5 mus rau 10 npaug ntawm cov khoom siv hlau. Txheeb xyuas los ntawm ANSYS simulation, nws tuaj yeem txo qhov kev vibration amplitude los ntawm ntau dua 90% hauv 0.3 vib nas this, ua kom muaj kev ruaj ntseg ntawm cov txheej txheem kev sib tsoo tuag, ua rau cov chip bonding lub kaum sab xis yuam kev tsawg dua 0.5 °, thiab ua tau raws li cov kev cai nruj ntawm LED chips rau qib qaij.
Chemical stability: Adaptable rau hnyav ntau lawm puag ncig
Nyob rau hauv LED ntim rhiav, tshuaj xws li fluxes thiab ntxuav cov neeg ua haujlwm feem ntau siv. Ordinary cov ntaub ntawv yog qhov yooj yim rau corrosion, uas tuaj yeem cuam tshuam rau lawv qhov tseeb. ZHHIMG yog tsim los ntawm cov zaub mov xws li quartz thiab feldspar. Nws muaj cov tshuaj lom neeg ruaj khov thiab ua haujlwm zoo heev rau acid thiab alkali corrosion. Tsis muaj cov tshuaj lom neeg pom tseeb nyob rau hauv pH ntau ntawm 1 txog 14. Kev siv lub sijhawm ntev yuav tsis ua rau cov hlau ion paug, ua kom huv si ntawm qhov chaw tuag thiab ua tau raws li cov cai ntawm ISO 14644-1 Chav Kawm 7 cov qauv kev huv huv, muab kev lees paub rau cov khoom ntim LED muaj kev ntseeg siab.
Precision processing muaj peev xwm: Ua tiav high-precision sib dhos
Relying ntawm ultra-precision ua tshuab, ZHHIMG tuaj yeem tswj lub tiaj tiaj ntawm lub hauv paus hauv ± 0.5μm / m thiab qhov roughness Ra≤0.05μm, muab cov ntaub ntawv qhia meej meej rau cov khoom siv xws li tuag lub taub hau thiab lub zeem muag. Los ntawm seamless kev koom ua ke nrog high-precision linear guides (rov ua dua qhov tseeb ± 0.3μm) thiab laser rangefinders (kev daws teeb meem 0.1μm), tag nrho qhov tseeb qhov tseeb ntawm cov khoom siv sib khi tuag tau nce mus rau qib ua hauv kev lag luam, txhawb kev siv thev naus laus zis rau kev lag luam LED.
Nyob rau hauv lub caij nyoog tam sim no ntawm kev hloov kho dua tshiab hauv LED kev lag luam, ZHHIMG, leveraging nws dual zoo nyob rau hauv cov ntaub ntawv kev ua tau zoo thiab kev tsim cov txheej txheem, muab ruaj khov thiab txhim khu kev qha precision lub hauv paus kev daws teeb meem rau tuag bonding khoom, txhawb LED ntim rau siab dua precision thiab efficiency, thiab tau dhau los ua ib tug tseem ceeb tsav tsheb quab yuam rau technological iteration nyob rau hauv kev lag luam.
