Ua kom zoo ib yam thaum lub sij hawm siab - ntimalumina ceramic laser txiavyog qhov nyuaj. Txawm tias tom qab cov txheej txheem validation, manufacturers tej zaum yuav ntsib microcracks, ntug fractures, ncua kev tawg, los yog drilling tsis xws luag vim variations ntawm cov khoom, laser tsis, fixturing, los yog ib puag ncig tej yam kev mob.
Phau ntawv qhia no piav qhia txog kev daws teeb meem kev ua haujlwm rau 355nm UV nanosecond laser txiav ntawm 96% thiab 99% alumina ceramic substrates nrog thicknesses feem ntau yog li ntawm 0.1 hli mus rau 1.5 hli.
Kauj Ruam 1. Txheeb xyuas hom Crack
Ua ntej kho cov txheej txheem tsis raug, txiav txim siab qhov tsis xws luag.
Hom crack hom muaj xws li:
---- Nto microcracks
---- Cov kab nrib pleb
---- Delamination
---- Ncua kev tawg
---- Los ntawm lub qhov tawg
Kev faib cov kev faib tsis zoo no pab txhim kho kev daws teeb meem.
Kauj Ruam 2. Tshawb xyuas lub workpiece
Txoj kev tshuaj xyuas pom zoo muaj xws li:
---- Optical microscope soj ntsuam
---- Metallographic tsom xam
---- SEM tshuaj xyuas (yog tias xav tau)
---- Ntug kev soj ntsuam zoo
---- Heat-affected zone (HAZ) kev soj ntsuam
Cov txheej txheem tshuaj xyuas yuav tsum raug xaiv raws li cov khoom yuav tsum tau ua.
Kauj ruam 3. Txheeb xyuas cov txheej txheem Laser
Tshawb xyuas cov txheej txheem tseem ceeb, suav nrog:
---- Laser nruab nrab lub zog
---- Pulse repetition zaus
---- Txiav ceev
---- Ua kom pom tseeb txoj hauj lwm
{{1}--- Layer-by-layer cutting depth
---- Pab roj siab
---- Scanning lub tswv yim
Tsis txhob cia siab rau qhov ntsuas qhov tseem ceeb, kev ua kom zoo dua yuav tsum yog raws li cov khoom siv ceramic, substrate thickness, laser qhov chaw, thiab cov khoom yuav tsum tau ua.
Kauj ruam 4. Txheeb xyuas qhov Fixturing System
Kev txhawb nqa lub cev tsis zoo tuaj yeem qhia txog kev ntxhov siab ntxiv thaum lub sijhawm ua haujlwm.
Cov khoom soj ntsuam pom zoo muaj xws li:
---- Nqus tuav ruaj khov
---- Fixture flatness
---- Kev them nyiaj yug workpiece
---- Pab roj nozzle sib dhos
---- Cua txias
Lub fixturing ruaj khov pab txhim kho qhov sib xws thiab txo qhov kev pheej hmoo tawg.
Kauj Ruam 5. Tshawb xyuas cov khoom lag luam zoo
Cov khoom lag luam ceramic zoo yuav tsum tau soj ntsuam.
Cov ntsiab lus tseem ceeb suav nrog:
---- Cov khoom siv purity
---- Sintering zoo
---- Cov qoob loo loj sib xws
---- Internal pores
---- Cov ntaub ntawv pov thawj
Cov khoom sib txawv feem ntau raug saib tsis pom thaum lub sij hawm daws teeb meem tab sis tuaj yeem cuam tshuam rau kev ua tau zoo.
Kauj ruam 6. Ua kom zoo dua ib qho Parameter ntawm ib lub sijhawm
Txhawm rau txheeb xyuas qhov laj thawj kom raug, hloov kho tsuas yog ib qho parameter thaum txhua qhov kev sim ua tiav.
Tej optimization muaj xws li:
---- Txo laser zog tawm tswv yim
---- nce txiav ceev
---- Optimizing scanning txoj kev
---- Txhim kho kev ua kom txias txias
---- Kho qhov chaw ua kom pom tseeb
Ib qho - kev ntsuas sib txawv muab cov txheej txheem txhim khu kev qha zoo tshaj plaws.
Tej yam txheej txheem tswj cov khoom
Txawm hais tias ua tiav qhov rais sib txawv nyob ntawm cov khoom siv thiab cov kev xav tau ntawm daim ntawv thov, cov tuam txhab feem ntau saib xyuas:
---- Laser tso zis stability
---- Pulse zaus
---- Txiav ceev
---- Ua kom pom tseeb txoj hauj lwm
---- Pab roj siab
---- Heat-affected zone (HAZ)
---- Ntug chipping
---- Kerf sib xws
---- Dimensional raug
---- Workpiece flatness
Cov ntsuas no muab cov ntaub ntawv siv tau los tsim cov txheej txheem tsim khoom ruaj khov dua li cov qauv thoob ntiaj teb.
Vim hais tias txhua daim ntawv thov sib txawv ntawm cov khoom muaj pes tsawg leeg, thickness, geometry, thiab cov khoom yuav tsum tau, cov kev ua tsis tau tiag tiag yuav tsum nco ntsoov validated los ntawm cov qauv kuaj es tsis yog luam ncaj qha los ntawm cov nqi siv.
👉 Hu rau peb cov kws tshaj lij hnub nothov kev kuaj dawb, sib tham txog koj cov kev xav tau ntau lawm, lossis tau txais a customized ceramic laser txiav tov los ntawm peb pab neeg engineering.
