Aluminum nitride yumbu wani nau’in yumbu ne mai yumbu tare da aluminum nitride (AIN) a matsayin babban lokaci na crystal. Etching karfe da’ira a kan aluminum nitride yumbu substrate ne aluminum nitride yumbu substrate.

1. Aluminum nitride yumbu ne mai yumbu tare da aluminum nitride (AIN) a matsayin babban lokaci na crystalline.

2. Ain crystal yana ɗaukar (ain4) tetrahedron azaman rukunin tsarin, mahaɗar haɗin gwiwa, yana da tsarin wurtzite kuma yana cikin tsarin hexagonal.

3. Chemical abun da ke ciki ai65 81%, N34. 19%, musamman nauyi 3.261g / cm3, fari ko launin toka fari, guda crystal colorless da m, sublimation da bazuwar zafin jiki a karkashin al’ada matsa lamba ne 2450 ℃.

4. Aluminum nitride yumbu ne mai high-zazzabi zafi-resistant abu tare da coefficient na thermal fadada (4.0-6.0) x10 (- 6) / ℃.

5. Polycrystalline ain yana da wutar lantarki na 260W / (mk), wanda shine sau 5-8 fiye da na alumina, don haka yana da kyakkyawan juriya na zafi kuma yana iya jure wa babban zafin jiki na 2200 ℃.

6. Aluminum nitride yumbura suna da kyakkyawan juriya na lalata.

Kwamitin kewayawa na yumbu yana da kyawawan kaddarorin mitoci da lantarki, kuma yana da kaddarorin da abubuwan da ake amfani da su na halitta ba su da su, kamar haɓakar yanayin zafi mai ƙarfi, kyakkyawan kwanciyar hankali na sinadarai da kwanciyar hankali na thermal. Yana da manufa marufi don sabon ƙarni na manyan-sikelin hadedde da’irori da ikon lantarki kayayyaki.

Kayan aikin Semiconductor da ake buƙata ta wuraren zama da kayan aikin masana’antu suna haɓaka cikin sauri, tare da babban amfani da wutar lantarki, babban haɗin gwiwa da daidaitawa, babban yanayin aminci da aiki mai mahimmanci. Sabili da haka, shirye-shiryen manyan kayan aikin wutar lantarki har yanzu matsala ce ta gaggawa da za a warware har yanzu. Abubuwan yumbu da aka dogara akan aluminium nitride suna da ingantattun kaddarorin da suka fi dacewa. Kuma bayan gwaje-gwaje daban-daban, sannu a hankali ya bayyana a cikin hangen nesa na mutane, kuma mafi girman filin aikace-aikacen shine samfuran LED masu ƙarfi.
A matsayin babban hanyar zafi mai gudana, aluminum nitride ceramic circuit board yana da mahimmanci a cikin aikace-aikacen marufi na LED mai ƙarfi. Yana taka muhimmiyar rawa wajen inganta haɓakar haɓakar zafi, rage yawan zafin jiki da inganta aminci da rayuwar sabis na na’urar.

LED sanyaya hukumar da’irar, yafi raba zuwa: LED hatsi kewaye hukumar da tsarin kewaye allon. LED hatsi kewaye hukumar ne yafi amfani a matsayin matsakaici na zafi makamashi fitarwa tsakanin LED hatsi da tsarin kewaye hukumar, wanda aka hade tare da LED hatsi ta aiwatar da waya zane, eutectic ko cladding.

Tare da haɓaka babban iko LED, yumbu kewaye allon shine babban allon kewayawa bisa la’akari da zubar da zafi: akwai hanyoyin shirye-shiryen gargajiya guda uku na da’ira mai ƙarfi:

1. M fim yumbu allon

2. Low zazzabi co kora multilayer yumbura

3. Thin film yumbu kewaye allon

Dangane da yanayin haɗuwa na LED hatsi da yumbu kewaye allon: zinariya waya, amma dangane da zinariya waya iyaka yadda ya dace da zafi dissipation tare da electrode lamba, don haka ya hadu da kwalabe na zafi dissipation.

Aluminum nitride yumbu mai yumbu zai maye gurbin allon da’ira na aluminum kuma ya zama mai kula da babbar kasuwar guntu ta LED a nan gaba.
