Nyob rau niaj hnub no lub sij hawm ntawm kev loj hlob technologies sai heev, ntau yam ntaub ntawv ua tau zoo tseem yuav tshwm sim. Ntawm lawv, Aluminium Nitride ceramic rings tau dhau los ua qhov tseem ceeb ntawm ntau qhov kev lag luam nrog lawv cov kev ua tau zoo thiab kev ua haujlwm dav dav.
Khoom siv
Aluminium Nitride, cov khoom siv tseem ceeb ntawm Aluminium Nitride ceramic nplhaib, yog cov khoom sib xyaw nrog cov khoom siv lub cev thiab tshuaj lom neeg. Nws yog covalently bonded los ua ib tug wurtzite qauv nrog 〔AIN4 〕tetrahedron raws li lub structural unit, teej tug mus rau lub hexagonal siv lead ua system15. Los ntawm kev pom ntawm cov tshuaj muaj pes tsawg leeg, cov ntsiab lus txhuas yog li 65.81%, cov ntsiab lus nitrogen yog li 34.19%, qhov tshwj xeeb lub ntiajteb txawj nqus yog li 3.261g / cm³, thiab feem ntau yog dawb lossis dawb. Hauv ib lub xeev crystal, nws tsis muaj xim thiab pob tshab. Nws sublimation decomposition kub nyob rau hauv ib txwm siab yog siab li 2450 degree, qhia zoo heev kub-kub stability.
Kev Ua Haujlwm Zoo
- Kev ruaj ntseg tshuaj lom neeg zoo: Aluminium Nitride rings muaj lub zog txhua yam thiab hardness, thiab tuaj yeem siv los ua cov ntim khoom tiv thaiv corrosion, cov kav dej hauv ob sab phlu, thiab cov ntaub ntawv tiv thaiv kub, thiab lwm yam.
- Kev rwb thaiv tsev hluav taws xob siab: Qhov kev tiv thaiv ntawm AIN ceramic nplhaib yog ntau dua 10¹³Ω・cm, uas tuaj yeem cais tawm tam sim no thiab yog cov khoom siv hluav taws xob zoo tshaj plaws.
- Cov khoom siv zoo heev: AlN rings muaj lub zog txhua yam thiab hardness, thiab lawv lub zog dabtsi yog khoov tuaj yeem siab li 400MPa lossis ntau dua, thiab tuaj yeem siv los tsim qee qhov chaw uas muaj zog txhua yam.
- High thermal conductivity: Tus nqi theoretical ntawm thermal conductivity ntawm Aluminium Nitride ceramics tuaj yeem ncav cuag li 320W / m・K, thiab thermal conductivity ntawm polycrystalline Aluminium Nitride tiag tiag npaj hauv kev lag luam kuj tuaj yeem ncav cuag 100-250W / m・K. Lub thermal conductivity ntawm Aluminium Nitride ceramic rings yog 5-10 lub sij hawm ntawm cov tsoos substrate cov ntaub ntawv xws li txhuas oxide, thiab lawv ua tau zoo nyob rau hauv daim ntawv thov nrog kub dissipation yuav tsum tau.
- Kev sib piv zoo ntawm thermal expansion coefficient: Lub thermal expansion coefficient ntawm Aluminium Nitride nplhaib sib tw nrog cov khoom siv semiconductor xws li silicon. Hauv kev ntim cov khoom siv semiconductor, nws tuaj yeem txhim kho kev ntseeg tau thiab ruaj khov ntawm cov cuab yeej.
- Tsis tshua muaj dielectric tsis tu ncua thiab dielectric poob: AlN ceramic rings muaj cov yam ntxwv ntawm qhov tsis tshua muaj dielectric tas li thiab dielectric poob, uas yog qhov tseem ceeb rau kev txhim kho cov kev sib txuas lus ntau zaus xws li 5G kev sib txuas lus thiab radar.
Cov ntaub ntawv kev lag luam
Nyob rau hauv xyoo tas los no, nrog rau kev loj hlob sai ntawm high-tech industries xws li cov ntaub ntawv hluav taws xob thiab lub zog tshiab, qhov kev thov rau cov ntaub ntawv ua tau zoo tau loj hlob tuaj. Raws li cov khoom siv tseem ceeb, kev lag luam loj ntawm AlN rings txuas ntxiv nthuav dav. Raws li cov ntaub ntawv hais txog kev lag luam, thoob ntiaj teb Aluminium Nitride ceramics kev lag luam tau tuav tus nqi loj hlob nyob rau ob peb xyoos dhau los thiab xav tias yuav loj hlob ntxiv rau yav tom ntej. Thiab nrog kev txhawb nqa dav dav ntawm 5G kev sib txuas lus thev naus laus zis, kev txhim kho ntawm kev txawj ntse ntse thiab kev nce siab ntawm Is Taws Nem ntawm Yam, cov khoom siv hluav taws xob tau muab cov qauv nruj dua ntawm kev ua haujlwm. Raws li kev ua haujlwm siab kub dissipation, rwb thaiv tsev thiab ntim khoom, qhov kev thov rau Aluminium Nitride ceramic rings nyob rau hauv kev ua lag luam yog qhia ib tug ntse nce.
