He aha ka alumini nitride ceramic substrate

ʻO ka substrate ceramic aluminika he substrate i hana ʻia me ka alumini nitride ceramic ma ke ʻano he kumu kumu.Ma ke ʻano he ʻano hou o ka substrate seramika, loaʻa iā ia nā hiʻohiʻona o ka conductivity thermal kiʻekiʻe, nā waiwai mechanical maikaʻi, ke kūpaʻa corrosion, nā waiwai uila maikaʻi loa, weldability a pēlā aku.He substrate hoʻoheheʻe wela maikaʻi a me nā mea hoʻopili no nā kaapuni hoʻohui nui.I nā makahiki i hala iho nei, me ka hoʻomohala wikiwiki ʻana o ka ʻoihana ʻike uila o ka honua, e hoʻomau ka hoʻomaikaʻi ʻana o nā koi o ka mākeke no ka hana ʻana o nā substrates seramika.Me kona mau hiʻohiʻona maikaʻi loa, hoʻomau ka hoʻonui ʻana o nā substrate seramika alumini nitride i kā lākou noi.

Wahi a nā hōʻike e pili ana, ʻo ke kumukūʻai mākeke honua o ka alumini nitride (AlN) ceramic substrates i hōʻea i 340 miliona yuan i 2019, a ke manaʻo ʻia nei e ulu i 620 miliona yuan ma 2026, me ka ulu ʻana o ka makahiki he 8.4%.

ʻO nā hiʻohiʻona nui o ka alumini nitride ceramic substrate:

(1) High thermal conductivity, ʻoi aku ma mua o 5 mau manawa o ka alumina ceramics;

(2) ʻO ka helu haʻahaʻa haʻahaʻa hoʻonui wela (4.5-10-6 / ℃) pili i ka semiconductor silicon material (3.5-4.0-10-6 / ℃);

(3) Haʻahaʻa dielectric mau

(4) ʻO nā waiwai insulating maikaʻi loa

(5) ʻOi aku ka ʻoi aku o ka ikaika flexural ma mua o Al2O3 a me BeO ceramics, a hiki ke hoʻopaʻa ʻia i ke kaomi maʻamau;

(6) Ke kū'ē i ka wela a me ke kū'ēʻana o ka metala i hoʻoheheʻeʻia
