Aluminiyamu nitride ceramic ndi mtundu wa zinthu zadothi ndi aluminium nitride (AIN) monga gawo lalikulu la kristalo. Etching zitsulo zozungulira pa aluminium nitride ceramic substrate ndi aluminium nitride ceramic substrate.

1. Aluminium nitride ceramic ndi ceramic yokhala ndi aluminium nitride (AIN) monga gawo lalikulu la crystalline.

2. Ain krustalo amatenga (ain4) tetrahedron ngati structural unit, covalent bond pawiri, ali ndi wurtzite dongosolo ndipo ndi wa hexagonal dongosolo.

3. Mankhwala zikuchokera ai65 81%, N34. 19%, mphamvu yokoka yeniyeni 3.261g/cm3, yoyera kapena imvi yoyera, kristalo imodzi yopanda utoto komanso yowonekera, sublimation ndi kutentha kwapang’onopang’ono ndi 2450 ℃.

4. Aluminium nitride ceramic ndi chinthu chopanda kutentha kwambiri chomwe chimakhala ndi coefficient of thermal expansion of (4.0-6.0) x10 (- 6) / ℃.

5. Polycrystalline ain imakhala ndi matenthedwe a 260W / (mk), omwe ndi 5-8 nthawi zambiri kuposa aluminiyamu, choncho imakhala ndi kutentha kwabwino kwa kutentha ndipo imatha kupirira kutentha kwa 2200 ℃.

6. Aluminium nitride ceramics ali ndi kukana kwa dzimbiri kwabwino kwambiri.

Ceramic circuit board ili ndi ma frequency afupipafupi komanso magetsi, ndipo imakhala ndi zinthu zomwe ma organic substrates alibe, monga matenthedwe apamwamba, kukhazikika kwamankhwala komanso kukhazikika kwamafuta. Ndizinthu zabwino zopangira zida zam’badwo watsopano wa mabwalo akuluakulu ophatikizika ndi ma module amagetsi amagetsi.

Zida za semiconductor zomwe zimafunidwa ndi malo okhala ndi zida zamafakitale zikukula mwachangu, ndikugwiritsa ntchito mphamvu zambiri, kuphatikiza kwakukulu ndikusintha modularization, chitetezo chapamwamba komanso ntchito yovuta. Choncho, kukonzekera zipangizo zamakono zopangira matenthedwe akadali vuto lachangu lomwe liyenera kuthetsedwa mpaka pano. Ma Ceramics opangidwa ndi aluminium nitride ali ndi mawonekedwe oyenera kwambiri. Ndipo pambuyo pa kuyesa kosiyanasiyana, pang’onopang’ono idawonekera m’masomphenya a anthu, ndipo gawo lalikulu kwambiri logwiritsira ntchito ndi zida zamphamvu za LED.
Monga njira yayikulu yoyendetsera kutentha, aluminium nitride ceramic circuit board ndiyofunikira pakuyika kwa LED yamphamvu kwambiri. Zimagwira ntchito yofunika kwambiri pakuwongolera kutentha kwa kutentha, kuchepetsa kutentha kwa mphambano ndikuwongolera kudalirika ndi moyo wautumiki wa chipangizocho.

LED yozizira dera bolodi imagawidwa kukhala: bolodi lozungulira la LED ndi bolodi yozungulira dongosolo. LED tirigu dera bolodi zimagwiritsa ntchito ngati sing’anga kutentha mphamvu kunja pakati LED njere ndi dongosolo dera bolodi, amene pamodzi ndi LED njere ndi ndondomeko kujambula waya, eutectic kapena cladding.

Ndi chitukuko cha magetsi amphamvu kwambiri a LED, bolodi loyang’anira dera la ceramic ndiye gulu lalikulu loyang’ana potengera kutentha kwa kutentha: pali njira zitatu zokonzekera zoyendetsa magetsi:

1. Thirani filimu ceramic bolodi

2. Kutentha kwapansi kumawotchedwa multilayer ceramics

3. Woonda filimu ceramic dera bolodi

Kutengera mawonekedwe ophatikizika a njere za LED ndi bolodi lozungulira la ceramic: waya wagolide, koma kulumikizidwa kwa waya wagolide kumachepetsa mphamvu ya kutentha kwapang’onopang’ono kukhudzana ndi ma elekitirodi, chifukwa chake amakumana ndi vuto la kutentha.

Aluminiyamu nitride ceramic gawo lapansi lidzalowa m’malo mwa aluminiyumu wozungulira bolodi ndikukhala mbuye wa msika wamagetsi apamwamba a LED mtsogolo.
