Aluminium Nitride: Qalabka Waxqabadka Sare ee Codsiyada Sare Waxqabadku wuu ka sarreeyaa kan Alumina Ceramic & High Purity Alumina Ceramic.Sida dhoobada horumarsan, waxay bixisaa kulaylka aan caadiga ahayn, dahaarka korantada, iyo xoogga farsamada, taasoo ka dhigaysa mid ku habboon in loo isticmaalo jawiga baahida. Alaabtan waxaa ka mid ah moduleka aluminium nitride, walxaha Aluminium Nitride, iyo qaybta Aluminium Nitride, mid kasta oo loogu talagalay inay buuxiso shuruudaha codsiga gaarka ah. Haddii loo isticmaalo sidii weel kuleyl ah, substrate semiconductor, ama curiye dhisme ah, Aluminium Nitride waxay bixisaa waxqabad la isku halayn karo iyo cimri dheer. Dulmarka alaabtani waxay muujinaysaa sifooyinka gaarka ah iyo noocyada kala duwan ee codsiyada. Aluminium Nitride waxaa loo yaqaanaa awoodda ay u leedahay in ay si wax ku ool ah u wareejiso kulaylka iyada oo la ilaalinayo sifooyinka dielectric aadka u fiican. Tani waxay si gaar ah ugu habboon tahay nidaamyada elektiroonigga ah ee heerkulka sare iyo awoodda sare leh. Maaddadu waxay sidoo kale u adkaysataa daxalka kiimikada iyo shoogga kulaylka, hubinta xasilloonida xaaladaha adag. Cufnaanteeda hoose iyo barta dhalaalka sare waxay sii kordhinaysaa ku habboonaanta isticmaalka hawada sare, baabuurta, iyo wax soo saarka warshadaha. Astaamaha muhiimka ah ee alaabtan Aluminium Nitride waxaa ka mid ah heerkulka sare ee kuleylka, kaas oo u oggolaanaya kuleylka waxtarka leh ee qalabka elektaroonigga ah. Waxa kale oo ay soo bandhigtaa dahaarka koronto ee wanaagsan, ka hortagga socodka aan la rabin iyo hubinta isku halaynta nidaamka. Maaddadu waa mid aan sun ahayn oo deegaan ahaan u wanaagsan, oo la jaanqaadaysa heerarka joogtada ah ee casriga ah. Intaa waxaa dheer, naqshadeynta moodeelka Aluminium Nitride module waxay u oggolaaneysaa isdhexgalka fudud ee nidaamyada jira, yareynta waqtiga rakibidda iyo kharashyada. Qaybaha waxaa lagu soo saaray iyadoo la adeegsanayo farsamooyin sax ah si loo hubiyo saxnaanta cabbirka iyo tayada joogtada ah. Marka la eego sharraxaadda faahfaahsan, Aluminium Nitride waa xarun la sameeyay iyadoo la isku daray aluminium iyo nitrogen. Waxaa lagu soo saaraa habab sintayn heersare ah oo kor u qaadaya hufnaantiisa qaabdhismeed iyo sifooyin waxqabad. Walaxda waxaa loo qaabayn karaa qaabab kala duwan, oo ay ku jiraan taarikada, ulo, iyo qaybo qaabaysan, taas oo ku xidhan isticmaalka loogu talagalay. Kala duwanaanshuhu wuxuu u oggolaanayaa dabacsanaan xagga codsiga ah, hadday tahay korantada elektiroonigga ah, iftiinka LED-ka, ama tignoolajiyada dareemayaasha. Qaybta Aluminium Nitride waxaa inta badan loo isticmaalaa wareegyada soo noqnoqda sare sababtoo ah luminta dielectric hooseeya iyo waxqabadka xasilloon ee waqtiga. Xaaladaha isticmaalka alaabtan waa kuwo ballaaran oo kala duwan. Dhinaca elektiroonigga ah, Aluminium Nitride waxaa caadi ahaan loo isticmaalaa sida substrate for gallium nitride (GaN) iyo silicon carbide (SiC), halkaas oo awooddeeda maaraynta kulaylku ay muhiim u yihiin. Warshadaha baabuurta, waxa laga shaqeeyaa qaybaha baabuurta korantada iyo nidaamyada maaraynta baytariga, halkaas oo xakamaynta kulaylka hufani ay lagama maarmaan tahay. Hawo-mareenka, maaddada waxaa loo adeegsadaa jawi kuleyl sare leh, sida qaybaha injiinka iyo guryaha dareemayaasha, halkaasoo laga yaabo in agab dhaqameedku fashilmaan. Intaa waxaa dheer, waxaa loo isticmaalaa qalabka caafimaadka, halkaas oo ku habboonaanta nooleheeda iyo iska caabbinta jeermiska ay ka dhigayso doorashada la door bidayo. Jawaab celinta isticmaaluhu waxay muujinaysaa in qaybaha Aluminium Nitride iyo qaybaha ay aad ugu qiimeeyaan waxqabadkooda iyo isku halaynta. Isticmaalayaal badan ayaa ka warbixiya hufnaanta nidaamka oo la hagaajiyay iyo nolol hawleed oo dheer marka la isticmaalayo alaabtan. Fududeynta is-dhexgalka iyo ku-habboonaanta tignoolajiyada jira ayaa sidoo kale lagu muujiyay faa'iidooyinka muhiimka ah. Isticmaalayaasha qaarkood waxay xusaan in walaxda kuleylkeeda sare ay si weyn u yareyso halista kulaylka ee codsiyada muhiimka ah. Kuwo kale waxay qadariyaan faa'iidooyinka deegaanka ee la xidhiidha wax soo saarkeeda iyo isticmaalkeeda. Guud ahaan, waayo-aragnimada wanaagsan ee isticmaalayaashu waxay xoojiyaan qiimaha Aluminium Nitride ee codsiyada tignoolajiyada casriga ah. Su'aalaha caanka ah ee ku saabsan alaabtan waxay inta badan ku wareegsan yihiin hantidooda, codsiyadooda, iyo maarayntooda. Mid ka mid ah su'aalaha badanaa la isweydiiyo ayaa ku saabsan kuleylka kuleylka ee Aluminium Nitride, kaas oo caadi ahaan ku dhow 180 W / m · K, taas oo ka dhigaysa mid ka mid ah kirishbooyada ugu fiican ee qalabka dhoobada. Weydiinta kale ee caadiga ah waxay khusaysaa heerkulka ugu sarreeya ee hawlgalka, kaas oo ka badan kara 2000 ° C, taas oo ku xidhan habka gaarka ah. Isticmaalayaashu waxay sidoo kale weydiiyaan ku-habboonka Aluminium Nitride iyo walxaha kale, maadaama ay guud ahaan si fiican ugu habboon tahay isticmaalka hababka isku-dhafka ah. Intaa waxaa dheer, su'aalaha ku saabsan helitaanka qaababka iyo cabbirrada la habeeyey ayaa soo noqnoqda, maadaama codsiyo badan ay u baahan yihiin xalal ku habboon. Ugu dambeyntii, su'aalaha ku saabsan dayactirka iyo kaydinta ayaa badanaa soo baxa, iyadoo la soo jeedinayo in alaabta lagu hayo meel qalalan oo qabow si loo ilaaliyo daacadnimadeeda.
