6 i loko o Silicon Carbide 4H-SiC Semi-Insulating Ingot, Dummy Grade Hōʻikeʻike Kiʻi

ʻO ka wehewehe pōkole:

Ke hoʻololi nei ʻo Silicon Carbide (SiC) i ka ʻoihana semiconductor, ʻoi aku ka nui o ka mana kiʻekiʻe, kiʻekiʻe-frequency, a me nā noi pale radiation. ʻO ka 6-inch 4H-SiC semi-insulating ingot, hāʻawi ʻia i ka papa dummy, he mea pono no ka prototyping, noiʻi, a me nā kaʻina hana calibration. Me kahi bandgap ākea, conductivity thermal maikaʻi loa, a me ka ikaika mechanical, lawelawe kēia ingot ma ke ʻano he koho kumu kūʻai no ka hoʻāʻo ʻana a me ka hoʻoponopono ʻana i ka hana me ka ʻole o ka hoʻololi ʻana i ke ʻano kumu e pono ai no ka hoʻomohala holomua. Hāʻawi kēia huahana i nā ʻano noi like ʻole, me ka uila uila, nā mea uila radio-frequency (RF), a me nā optoelectronics, e lilo ia i mea waiwai nui no ka ʻoihana a me nā keʻena noiʻi.

Pono o Dummy-Grade Material

Kūʻai kūpono:
ʻO ka papa dummy kahi koho ʻoi aku ka maʻalahi no ka noiʻi a i ʻole nā mea hana-papa hana, i mea kūpono no ka hoʻāʻo maʻamau a me ka hoʻomaʻemaʻe kaʻina hana.

Hiki ke hoʻopilikino:
ʻO nā ana i hoʻonohonoho ʻia a me nā ʻano aniani e hōʻoia i ka hoʻohālikelike ʻana me kahi ākea o nā noi.

Hiki ke hoʻonui:
Hoʻopili ke anawaena 6-inihi me nā kūlana ʻoihana, e ʻae ana i ka scaling seamless i nā kaʻina hana-grade.

ʻO ka ikaika:
ʻO ka ikaika mechanical kiʻekiʻe a me ka paʻa wela e paʻa a paʻa i ka ingot ma lalo o nā kūlana hoʻokolohua like ʻole.

ʻAno kūpono:
He kūpono no nā ʻoihana he nui, mai nā ʻōnaehana ikehu a hiki i ke kamaʻilio a me ka optoelectronics.

Ka hopena

ʻO ka 6-inch Silicon Carbide (4H-SiC) semi-insulating ingot, dummy grade, hāʻawi i kahi kahua hilinaʻi a maʻalahi no ka noiʻi, prototyping, a me ka hoʻāʻo ʻana i nā ʻāpana ʻenehana ʻokiʻoki. ʻO kāna mau mea wela, uila, a me ka mechanical, i hui pū ʻia me ka affordability a me ka customizability, e lilo ia i mea waiwai nui no ka ʻoihana a me ka ʻoihana. Mai ka uila uila a hiki i nā ʻōnaehana RF a me nā mea paʻakikī paʻakikī, kākoʻo kēia ingot i ka hana hou i kēlā me kēia pae o ka hoʻomohala ʻana.
No nā kikoʻī kikoʻī hou aku a i ʻole ke noi ʻana i kahi ʻōlelo, e ʻoluʻolu e leka uila mai iā mākou. Ua mākaukau kā mākou hui ʻenehana e kōkua me nā ʻōlelo hoʻoponopono e hoʻokō i kāu mau koi.
