(Bishyushye cyane AlNByakozwe naWintrustek)
Nitride ya aluminium (AIN) irazwi cyane kubera ubushyuhe bwiza bwumuriro hamwe nimiterere idasanzwe yamashanyarazi. Nibintu bisanzwe bya ceramic bikoreshwa mubikoresho byinshi byamashanyarazi. Ceramics ya aluminium nitride irwanya ibyuma bishongeshejwe, birimo umuringa, lithium, na aluminiyumu, hiyongereyeho kwaguka kw’umuriro hamwe n’imiterere y’amashanyarazi. Nitride ya aluminiumni ibikoresho byingirakamaro mubikorwa bitandukanye byinganda bitewe nubumara bwimiterere nubumubiri.
Nyamara, mubikorwa, nitride ya aluminium itandukanijwe muburyo bubiri bushingiye kubikorwa byo gucumura: pressureless yacumuye aluminium nitride naashyushye-ya aluminium nitride. Ibiranga nibisabwa muribi byiciro byombi biratandukanye cyane.
Nitride ya aluminiyumukuvanga ifu ya aluminium nitride yuzuye cyane hamwe nubufasha buke bwo gucumura (nka Y2O3), gushiraho imvange muburyo bwifuzwa (urugero, gukanda byumye cyangwa gukanda isostatike), hanyuma ukabicumura mubushyuhe bwinshi (1800 ° C kugeza 2000 ° C) munsi yikirere gikingira (azote). Ubu buryo bushingiye ku myitwarire iri hagati yimfashanyo yo gucumura na alumina igaragara hejuru yubutaka bwa AlN, ikora icyiciro cyamazi gitera guhinduranya no kwiyongera kwingirangingo.
Ibiranga:
Igiciro cyo hasi: ibikoresho bisabwa biroroshye byoroshye, bigatuma bikwiranye n’umusaruro munini.
Imiterere igoye: irashobora gukora ibice bitandukanye byuburyo budasanzwe hamwe namasahani yoroheje (nka ceramic substrates).
Imikorere: nubwo ishobora guhaza ibyifuzo byinshi byinganda, kubera kubura umuvuduko wo hanze, utwobo duto duto tuboneka mubintu, kandi ubucucike buri hagati ya 97% na 99%.
Porogaramu nyamukuru:
Amashanyarazi apakira ibikoresho (nka LED na module module)
Ubushyuhe burashiramo hamwe na gasketi
Ibikoresho birwanya ruswa kandi birwanya ubushyuhe
Nitride ya aluminiyumu ishyushyeikorwa hifashishijwe inzira idasanzwe yitwa gukanda. Mugihe cy'ubushyuhe bwo hejuru, umuvuduko mwinshi uterekejweho na megapasikali amagana. Izi ngaruka zubushyuhe bwo hejuru hamwe numuvuduko mwinshi nurufunguzo rwo kugera kubikorwa byihariye.
Ibiranga:
Ubucucike bukabije cyane: igitutu gisohora imyenge iri hagati yuduce, bikavamo ubucucike bushobora kwegera agaciro kerekana (＞ 99%).
Ibikoresho byiza bya mashini: ugereranije na AlN isanzwe icumura, AlN ishyushye cyane AlN ifite imbaraga zoroshye kandi zikomeye.
Ubushuhe buhebuje bwumuriro: kubera ubukana buke cyane, gutatanya fonon biragabanuka, kandi nubushyuhe bwumuriro mubusanzwe burahagaze neza kandi hafi yumupaka wo hejuru.
Imipaka ntarengwa: igiciro kinini, umusaruro muke, kandi mubisanzwe gusa imiterere ya geometrike gusa nka disiki cyangwa bloks zirashobora gutunganywa.
Porogaramu nyamukuru (ibisabwa byihariye-bisabwa byihariye):
Gushyushya gusohora no gupakira amashanyarazi menshi
Ibisekuru bizakurikiraho-imbaraga nyinshi za radiyo yumurongo / ibikoresho bya microwave
Ubushyuhe bwo gukwirakwiza sisitemu ya elegitoroniki yizewe cyane mu kirere
Ibikoresho byubushakashatsi cyangwa ibipimo byo gupima mubihe bimwe bikabije
Nigute ushobora guhitamo?
Hitamonitride ya aluminiumniba: Urimo ukorana nu mbaho za elegitoronike (PCBs), LED yubushyuhe, cyangwa ibikoresho byoroheje byinganda. Nitride ya aluminium idafite imbaraga nigiciro cyinshi kandi gikuze.
Hitamoashyushye-ya aluminium nitrideniba: Ibidukikije byawe birasaba cyane, nka chucks ya electrostatike (ESCs) kubikoresho byo mu gice cya semiconductor, ibikoresho bya lazeri ikora cyane, cyangwa ibice byubaka bigomba guhangana ningutu zikomeye. Ubucucike n'imbaraga za nitride ya aluminiyumu ishyushye ntisimburwa muribi bihe.
