I-Aluminium nitride ceramic iwuhlobo lwe-ceramic material ene-aluminium nitride (AIN) njengesigaba sekristalu esiyinhloko. Ukuhlanganisa isekethe yensimbi ku-aluminium nitride ceramic substrate i-aluminium nitride ceramic substrate.

1. I-Aluminium nitride ceramic iyi-ceramic ene-aluminium nitride (AIN) njengesigaba sekristalu esiyinhloko.

2. I-Ain crystal ithatha (i-ain4) i-tetrahedron njengeyunithi yesakhiwo, inhlanganisela yebhondi ehlangene, inokwakheka kwe-wurtzite futhi ingeyesistimu enezinhlangothi ezine.

3. Ukwakheka kwamakhemikhali ai65 81%，N34. I-19%, amandla adonsela phansi athile angu-3.261g/cm3, amhlophe noma ampunga amhlophe, ikristalu elilodwa elingenambala futhi libonisa obala, izinga lokushisa le-sublimation kanye nokubola ngaphansi kwengcindezi evamile ngu-2450 ℃.

4. I-Aluminium nitride ceramic iyinto ekwazi ukumelana nokushisa okuphezulu ene-coefficient of thermal expansion (4.0-6.0) x10 (- 6) / ℃.

5. I-Polycrystalline ain ine-conductivity eshisayo engu-260W / (mk), ephakeme izikhathi ezingu-5-8 kune-alumina, ngakho inokumelana nokushaqeka okuhle kokushisa futhi ingakwazi ukumelana nokushisa okuphezulu kwe-2200 ℃.

6. I-Aluminium nitride ceramics inokumelana nokugqwala okuhle kakhulu.

Ibhodi lesifunda se-Ceramic linezakhiwo ezinhle ze-high-frequency kanye nezamandla kagesi, futhi linezakhiwo ezingenayo i-organic substrates, njengokuhamba okuphezulu kwe-thermal, ukuqina okuhle kakhulu kwamakhemikhali kanye nokuzinza kokushisa. Kuyimpahla efanelekile yokupakisha yesizukulwane esisha samasekethe amakhulu ahlanganisiwe namamojula we-elekthronikhi wamandla.

Izinsimbi ze-Semiconductor ezidingwa izindawo zokuhlala kanye nemishini yezimboni zithuthuka ngokushesha, ngokusetshenziswa kwamandla aphezulu, ukuhlanganiswa okuphezulu kanye ne-modularization, isici sokuphepha esiphezulu nokusebenza okubucayi. Ngakho-ke, ukulungiswa kwezinto eziphezulu ze-thermal conductivity kuseyinkinga ephuthumayo okufanele ixazululwe kuze kube manje. Izitsha zobumba ezisekelwe ku-aluminium nitride zinezakhiwo ezifanele kakhulu eziphelele. Futhi ngemva kokuhlolwa okuhlukahlukene, kuye kwavela kancane kancane embonweni wabantu, futhi inkambu enkulu yohlelo lokusebenza yimikhiqizo ye-LED enamandla amakhulu.
Njengomzila oyinhloko wokugeleza kokushisa, ibhodi lesekethe ye-aluminium nitride ceramic ibalulekile ekufakweni kokupakisha kwe-LED enamandla amakhulu. Idlala indima ebaluleke kakhulu ekuthuthukiseni ukusebenza kahle kokukhipha ukushisa, ukunciphisa izinga lokushisa lokuhlangana kanye nokwenza ngcono ukuthembeka nempilo yesevisi yedivayisi.

Ibhodi lesifunda lokupholisa i-LED lihlukaniswe ikakhulukazi: ibhodi lesifunda lezinhlamvu ze-LED kanye nebhodi lesifunda lesistimu. Ibhodi lesifunda lezinhlamvu ze-LED lisetshenziswa kakhulu njengendlela yokuthunyelwa kwamandla okushisa phakathi kokusanhlamvu kwe-LED nebhodi lesifunda lesistimu, elihlanganiswe nokusanhlamvu kwe-LED ngenqubo yokudweba ngocingo, i-eutectic noma i-cladding.

Ngokuthuthukiswa kwe-LED enamandla amakhulu, ibhodi lesifunda se-ceramic liyibhodi lesifunda eliyinhloko elisekelwe ekucabangeni kokukhipha ukushisa: kunezindlela ezintathu zendabuko zokulungiselela isekethe yamandla aphezulu:

1. Ibhodi le-ceramic yefilimu ewugqinsi

2. Izinga lokushisa eliphansi co lishise izitsha zobumba eziningi

3. Ifilimu elincane lebhodi lesifunda se-ceramic

Ngokusekelwe kumodi yenhlanganisela yokusanhlamvu kwe-LED kanye nebhodi lesifunda se-ceramic: intambo yegolide, kodwa ukuxhunywa kwentambo yegolide kukhawulela ukusebenza kahle kokukhipha ukushisa eduze kokuxhumana kwe-electrode, ngakho ihlangabezana nebhodlela lokukhipha ukushisa.

I-Aluminium nitride ceramic substrate izongena esikhundleni sebhodi lesekhethi ye-aluminium futhi ibe inkosi enamandla amakhulu emakethe ye-chip ye-LED esikhathini esizayo.
