Advanced ceramic substrates tau dhau los ua cov ntaub ntawv tseem ceeb hauv cov ntim khoom semiconductor, cov khoom siv hluav taws xob hluav taws xob, RF cov khoom siv, thiab cov khoom siv hluav taws xob ua tau zoo tshaj -. Ntawm lawv, alumina (Al₂O₃) thiab txhuas nitride (AlN) yog ob feem ntau siv engineering ceramics.
Txawm hais tias cov ntaub ntawv no yuav zoo sib xws, lawv teb txawv heev thaum lub sij hawm ua laser.
Rau cov tuam txhab tsim cov khoom lag luam precision ceramic substrates, kev nkag siab qhov sib txawv no yog qhov tseem ceebthaum xaiv cov khoom siv laser, tsim cov txheej txheem kev ua haujlwm, thiab kwv yees cov nqi tsim khoom.
Feem ntau, AlN yog qhov nyuaj rau cov txheej txheem laser dua li Al₂O₃ thaum muaj kev ua haujlwm siab, qis ntug chipping, thiab kev ntseeg siab yuav tsum tau. Kab lus no piav qhia vim li cas los ntawm qhov kev xav ntawm cov khoom siv, laser- cov khoom sib cuam tshuam, txheej txheem kev ruaj ntseg, thiab kev tsim khoom.
Khoom Khoom: Vim li cas AlN coj txawv txawv
Lub ntsiab yog vim li cas nyob rau hauv lub cev khoom ntawm ob cov ntaub ntawv.
| Khoom | Alumina (Al₂O₃) | Aluminium Nitride (AlN) | Kev cuam tshuam rau Laser Txiav |
| Thermal conductivity | Nruab nrab | Siab heev | Thaum tshav kub kub dissipates sai dua nyob rau hauv AlN, ua rau lub zog tswj nyuaj dua. |
| Thermal expansion | Siab dua | qis | Cov cwj pwm thermal sib txawv cuam tshuam rau kev faib tawm kev ntxhov siab thaum ua haujlwm. |
| Fracture toughness | Zoo sib xws | Zoo sib xws | Ob qho khoom siv yog nkig thiab rhiab rau thermal stress. |
| Melting/decomposition cwj pwm | Feem ntau melts ntawm qhov kub siab heev | Tej zaum yuav decompose ib nrab nyob rau hauv qhov chaw siab -kub laser raug | Nto zoo thiab kev ua haujlwm hluav taws xob yuav tsum tau ua tib zoo saib thaum ua AlN. |
Tsis zoo li alumina, AlN yog tsim los hloov cov cua sov kom zoo. Txawm hais tias qhov no ua rau nws yog qhov zoo tshaj plaws substrate rau siab - fais fab hluav taws xob, nws kuj uaprecision laser machiningtseem ceeb dua xav tau.
Aluminium Nitride (AlN) cuam tshuam rau Laser Txiav
1. High Thermal Conductivity tsim lub qhov rais txheej txheem nqaim
Qhov kev sib tw loj tshaj plaws thaum txiav AlN yog nws cov thermal conductivity siab heev.
Raws li lub zog laser nkag mus rau hauv cov khoom, cov cua kub kis tau sai sai ntawm qhov chaw txiav es tsis txhob muaj cov concentrated nyob ze ntawm kerf.
Qhov no tsim ob qhov kev sib tw ua tau zoo:
Ntau lub zog laser feem ntau yuav tsum tau ua kom ruaj khov cov khoom tshem tawm.
Kev hloov pauv me me tuaj yeem muaj txiaj ntsig ntau dua rau kev ua haujlwm zoo.
Piv nrog alumina, AlN feem ntau muab cov txheej txheem nqaim dua. Optimizing laser fais fab tuag, scanning ceev, mem tes sib tshooj, thiab txiav lub tswv yim yog li ntawd yuav ua ib qho tseem ceeb heev.
2. Nto Chemistry yog rhiab heev
Lwm qhov sib txawv tseem ceeb yog cov khoom siv tus cwj pwm ntawm qhov kub siab.
Thaum lub sijhawm ua haujlwm laser hauv cheeb tsam, AlN tuaj yeem ua rau qee qhov decomposition lossis oxidation nyob ntawm qhov chaw ua haujlwm thiab thermal tej yam kev mob. Qee zaum, cov khoom siv hlau hlau lossis cov khoom siv tshuaj tiv thaiv tuaj yeem tshwm sim ntawm qhov chaw txiav.
Cov kev hloov saum npoo no tuaj yeem cuam tshuam:
Hluav taws xob rwb thaiv tsev
Kev huv ntawm qhov chaw
Metallization zoo
Tom qab brazing lossis txheej txheej txheem
Rau cov khoom siv hluav taws xob semiconductor, kev tswj xyuas kom huv, kev ruaj khov txiav ntug feem ntau tsuas yog qhov tseem ceeb raws li kev ua tiav qhov tseeb.
Ua tib zoo tswjUV laser uatuaj yeem txo cov teebmeem no.
3. Cov kab nrib pleb thiab ntug chipping yog qhov nyuaj rau tswj
Ob leeg Al₂O₃ thiab AlN yog nkig ceramics.
Txawm li cas los xij, vim tias AlN hloov cov cua sov kom zoo dua, lub zog laser ntau dhau tuaj yeem tsim cov thermal gradients loj dua thaum lub tshuab ua haujlwm yog tias cov txheej txheem tsis raug kho kom zoo.
Yog li ntawd, manufacturers tuaj yeem pom:
Ntug chipping
Khaub ncaws tawg
Subsurface microcracks
Ncua tawg propagation tom qab ua
Rau siab -cov ntawv thov kev ntseeg siab xws li automotive power modules lossis semiconductor tej pob khoom, cov microscopic defects yuav txo tau ntev -lub sij hawm ntseeg tau txawm tias lawv tsis pom ntawm qhov muag liab qab.
Qhov no yog ib qho laj thawj vim li cas cov txheej txheem txiav cov txheej txheem feem ntau nyiam tshaj qhov hnyav siab - zog txiav.
4. Precision Micro-Machining yog xav tau ntau dua
Qhov sib txawv tau pom meej dua thaum lub sijhawm micro-machining.
Cov txheej txheem xws li:
Micro qhov
Cov qhov me me
Me - vojvoog kaum
Fine contour txiav
xav tau lub zog laser ruaj khov thiab tswj tau qhov tseeb.
Rau alumina substrates, cov yam ntxwv no feem ntau tuaj yeem tsim los siv zoo -tsim cov txheej txheem tsis zoo.
Rau AlN substrates, txawm li cas los xij, cov neeg tsim khoom feem ntau siv sijhawm ntau dua los ua kom zoo dua:
Txheej thickness
Pulse sib tshooj
Kev soj ntsuam zoo
Cov cua txias
Gas kev pab
5. Cov khoom siv yuav tsum siab dua
Ua AlN ua tiav tsis yog tsuas yog xaiv qhov tseeb laser wavelength.
Tshuab stability kuj tseem ceeb zuj zus.
Rau precision AlN txiav, manufacturers feem ntau nyiam tshuab nruab nrog:
Qhov chaw ruaj khov UV laser
High -kev xa khoom zoo
Precision galvanometer scanners
Muaj tseeb motion platforms
Txhim khu kev tswj qhov kub thiab txias
Pab tau zoo -gas tswj
Siab - daws teeb meem pom kev sib haum xeeb
Lub tshuab muaj peev xwm ua tiav cov alumina ntseeg tau tseem yuav xav tau kev ua kom zoo dua ntxiv ua ntej yuav ua tau zoo -AlN qhov zoo.
Qhov Laser Qhov Zoo Tshaj Plaws rau AlN?
Rau nyias thiab nruab nrab-thickness AlN ceramic substrates siv nyob rau hauv semiconductor thiab hluav taws xob daim ntaub ntawv, 355 nm UV nanosecond lasers tseem yog cov feem ntau siv tshuaj.
Lawv qhov zoo muaj xws li:
Cov cua sov me me- thaj chaw cuam tshuam
Zoo heev qhov tseeb
Tsawg ntug chipping
Stable contour txiav
Zoo sib xws nrog precision micro-feature
Ultrafast picosecond thiab femtosecond lasers tuaj yeem txo cov teebmeem thermal ntxiv tab sis feem ntau xaiv tsuas yog rau cov ntawv thov uas xav tau siab heev lossis kev ntseeg tau tshwj xeeb.
AlN vs. Alumina: Ib qho piv txwv
| Kev sib piv | Alumina (Al₂O₃) | Aluminium Nitride (AlN) |
| Txheej txheem stability | Zoo heev | Ntau rhiab heev rau parameter variation |
| Ntug zoo | Yooj yim rau optimize | Yuav tsum tau tswj cov txheej txheem nruj dua |
