Aluminium nitride ceramic imhando yeceramic material ine aluminium nitride (AIN) sechikamu chikuru chekristaro. Etching simbi yedunhu paaluminium nitride ceramic substrate ndeye aluminium nitride ceramic substrate.

1. Aluminium nitride ceramic is a ceramic ine aluminum nitride (AIN) sechikamu chikuru checrystalline.

2. Ain crystal inotora (ain4) tetrahedron sechikamu chechimiro, covalent bond compound, ine wurtzite structure uye ndeye hexagonal system.

3. Mushonga wemakemikari ai65 81%, N34. 19%, chaiyo giravhiti 3.261g/cm3, chena kana grey chena, imwe kristaro isina ruvara uye yakajeka, sublimation uye kuora tembiricha pasi pekumanikidzwa kwakajairwa i2450 ℃.

4. Aluminium nitride ceramic chinhu chepamusoro-tembiricha chinodzivirira kupisa chine coefficient yekuwedzera kwekushisa kwe (4.0-6.0) x10 (- 6) / ℃.

5. Polycrystalline ain ine thermal conductivity ye 260W / (mk), iyo inosvika 5-8 nguva yakakwirira kupfuura yealumina, saka ine yakanaka yekupisa kupisa kusagadzikana uye inogona kumira kupisa kwepamusoro kwe2200 ℃.

6. Aluminium nitride ceramics ine yakanakisa corrosion resistance.

Ceramic circuit board ine yakanaka high-frequency uye magetsi ehupfumi, uye ine zvivakwa izvo organic substrates haina, senge yakakwira yekupisa conductivity, yakanakisa kugadzikana kwemakemikari uye kugadzikana kwekupisa. Iyo yakanakira kurongedza zvinhu zvechizvarwa chitsva cheakakura-akasanganiswa maseketi uye simba emagetsi modules.

Semiconductor zviridzwa zvinodiwa nenzvimbo dzekugara uye zvigadzirwa zvemaindasitiri zviri kukurumidza kukurumidza, nekushandiswa kwesimba kwakanyanya, kusanganisa kwepamusoro uye modularization, yakakwirira kuchengetedza chinhu uye mashandiro ane hanya. Nokudaro, kugadzirira kwepamusoro-soro conductivity zvinhu zvichiri dambudziko rekukurumidzira kugadziriswa kusvika ikozvino. Maceramics akavakirwa paaluminium nitride ane akakodzera akazara zvivakwa. Uye mushure mekuedza kwakasiyana-siyana, yave ichionekwa zvishoma nezvishoma muchiratidzo chevanhu, uye nzvimbo huru yekushandiswa ndeye-high-power LED zvigadzirwa.
Seyo nzira huru yekuyerera kwekupisa, aluminium nitride ceramic wedunhu bhodhi yakakosha mukurongedzerwa kwekushandisa kwe-high-simba LED. Inoita basa rakakosha pakuvandudza kupisa kwekupisa, kuderedza tembiricha yekusangana nekuvandudza kuvimbika uye hupenyu hwebasa remudziyo.

LED inotonhorera redunhu bhodhi rinonyanya kukamurwa kuita: LED tsanga redunhu bhodhi uye system redunhu bhodhi. LED tsanga redunhu bhodhi rinonyanya kushandiswa sepakati yekupisa simba kunze kwenyika pakati pezviyo zve LED uye system redunhu bhodhi, iyo inosanganiswa ne LED tsanga nenzira yekudhirowa waya, eutectic kana cladding.

Nekuvandudzwa kwe-high-power LED, ceramic circuit board ndiyo huru yedunhu bhodhi zvichienderana nekufunga kwekupisa kupisa: kune nzira nhatu dzekugadzirira dzepamusoro-simba redunhu:

1. Gobvu firimu ceramic board

2. Low tembiricha co fired multilayer ceramics

3. Mutete firimu zvedongo redunhu bhodhi

Zvichienderana nemusanganiswa wemhando yezviyo zve LED uye ceramic dhizaini bhodhi: waya yegoridhe, asi kubatana kwewaya yegoridhe kunodzikamisa kushanda kwekupisa kwekupisa pamwe chete neelectrode contact, saka inosangana nebhodhoro rekubvisa kupisa.

Aluminium nitride ceramic substrate inotsiva aluminium wedunhu bhodhi uye yova mukuru wepamusoro-simba LED chip musika mune ramangwana.
