(Pumi wela AlNHana ʻia eWintrustek)
Aluminum nitride (AIN) Ua kaulana ia no kona conductivity thermal maikaʻi loa a me nā ʻano insulating uila. He mea maʻamau ia i hoʻohana ʻia i ka nui o nā mea uila. Kūleʻa nā seramika nitride alumini i nā metala hoʻoheheʻe ʻia, me ke keleawe, ka lithium, a me ka aluminika, me ka hoʻonui ʻana i ka wela a me nā waiwai insulating uila. Aluminum nitridehe mea pono i loko o nā ʻano hana ʻoihana like ʻole ma muli o kona mau mea kemika a me ke kino.
Eia naʻe, i ka hana ʻana, ua hoʻokaʻawale ʻia ka nitride aluminika i ʻelua mau ʻano e pili ana i ke kaʻina sintering: pressureless sintered alumini nitride anitride alumini wela. ʻOkoʻa loa nā hiʻohiʻona a me nā hoʻohana ʻana o kēia mau ʻano ʻelua.
Aluminum nitride puʻehoʻohui i ka pauka nitride aluminika maʻemaʻe kiʻekiʻe me kahi mea liʻiliʻi o kahi kōkua sintering (e like me Y2O3), e hoʻoheheʻe i ka hui ʻana i ke ʻano i makemake ʻia (e laʻa, ma ke kaomi maloʻo a i ʻole ke kaomi isostatic), a laila hoʻopaʻa ʻia i kahi wela kiʻekiʻe (1800 ° C a 2000 ° C) ma lalo o kahi ea palekana (nitrogen). Ke hilinaʻi nei kēia kaʻina hana i ka hopena ma waena o ke kōkua sintering a me ka alumina i loaʻa ma ka ʻili o nā ʻāpana AlN, e hana ana i kahi wai wai e hoʻoikaika i ka hoʻonohonoho hou ʻana a me ka hoʻopaʻa ʻana o nā ʻāpana.
Nā hiʻohiʻona:
ʻO ke kumu kūʻai haʻahaʻa: he maʻalahi nā koi o nā mea hana, kūpono ia no ka hana nui nui.
Nā ʻano paʻakikī: hiki iā ia ke hana i nā ʻāpana like ʻole a me nā papa lahilahi (e like me nā substrate ceramic).
Hana: ʻoiai hiki iā ia ke hoʻokō i ka hapa nui o nā pono ʻoihana, ma muli o ka nele o ke kaomi o waho, hiki ke maʻalahi nā pores liʻiliʻi i loko o ka mea, a ʻo ka maʻamau ma waena o 97% a me 99%.
Nā noi nui:
ʻO nā mea hoʻopihapiha hoʻopihapiha semiconductor (e like me ka LED a me nā substrate module mana)
Heat sinks a me insulating gaskets
ʻO nā mea ʻenehana pale-corrosion a me ka wela
Nitride alumini welahana ʻia me ka hoʻohana ʻana i kahi hana kūikawā i kapa ʻia ʻo ke kaomi wela. I ka wā o ka sintering kiʻekiʻe, hoʻohana ʻia kahi kaomi kiʻekiʻe unidirectional o nā ʻumi a i ʻole mau haneli megapascals i ka mea. ʻO kēia hopena synergistic o ka wela kiʻekiʻe a me ke kaomi kiʻekiʻe ke kī i ka hoʻokō ʻana i kāna hana ʻokoʻa.
Nā hiʻohiʻona:
Kiʻekiʻe kiʻekiʻe loa: hoʻoneʻe ke kaomi i nā pores ma waena o nā ʻāpana, e loaʻa ana i kahi mānoanoa hiki ke hoʻokokoke i ka waiwai kumu (>99%).
99%).
ʻOi aku ka maikaʻi o nā waiwai mīkini: hoʻohālikelike ʻia me AlN i hoʻopaʻa ʻia maʻamau, ʻoi aku ka ikaika o ka flexural a me ka paʻakikī o AlN i kaomi wela.
ʻOi aku ka maikaʻi o ka hoʻoili wela: ma muli o ka porosity haʻahaʻa loa, ua hoʻemi ʻia ka hoʻopuehu ʻana o ka phonon, a ʻoi aku ka paʻa o kāna conductivity thermal a kokoke i ka palena kiʻekiʻe.
Nā palena: ke kumu kūʻai kiʻekiʻe, ʻoi aku ka maikaʻi o ka hana ʻana, a maʻamau wale nō nā ʻano geometric maʻalahi e like me nā disc a i ʻole nā poloka hiki ke hana ʻia.
Nā noi nui (nā koi kūikawā kiʻekiʻe):
ʻO ka hoʻopau ʻana i ka wela a me ka hoʻopili ʻana o nā lasers mana kiʻekiʻe
ʻO ka hanauna hou aku ka mana kiʻekiʻe kiʻekiʻe o ka lekiō / nā mīkini uila
Hoʻopau wela no nā ʻōnaehana uila hilinaʻi ultra-kiʻekiʻe ma ke kahua aerospace
ʻO nā lako noiʻi ʻepekema a i ʻole nā mea hoʻāʻo benchmark ma lalo o kekahi mau kūlana koʻikoʻi
Pehea ʻoe e koho ai?E kohonitride alumini kaomi ʻole
inā: Ke hana nei ʻoe me nā papa kaapuni uila (PCB), nā kukui wela LED, a i ʻole nā mea hoʻokaʻawale ʻoihana maʻalahi. ʻO ka nitride alumini paʻi ʻole ka koho ʻoi aku ka maikaʻi a me ke koho makua.E kohonitride alumini wela
