Looxyada Wareega dhoobada Alumina ee Waxqabadka Sare leh ee Elektarooniga Sare
Marka la eego qalabka elektiroonigga ah ee casriga ah, maareynta kulaylka iyo korantada korantada ayaa ah arrimo muhiim ah oo go'aaminaya cimriga dheer iyo kalsoonida aaladaha awoodda sare leh. Alumina Ceramic Circuit Board waxay u soo baxday sidii xal sare oo loogu talagalay injineerada doonaya inay ka gudbaan xaddidaadda substrate-ka dabiiciga ah sida FR4 ama PCB-yada asaasiga ah. Sharaxaada alaabadani waxay sahamisaa sifooyinka gaarka ah ee 96% Alumina Ceramic Circuit agabka Gudida, iyadoo tafaasiilaysa sida ay u bixiyaan waxqabadka adag ee deegaan baahida loo qabo. Haddii aad u baahan tahay qaabaynta caadiga ah ama aad ku lug leedahay Nakhshadeynta Guddiga Wareegga Alumina, fahamka nuucyada dhoobada aluminium oxide ayaa lagama maarmaan u ah hagaajinta nidaamyadaaga elektiroonigga ah.
Dulmar tignoolajiyada dhoobada Alumina
Aasaaska tignoolajiyadaani waxay ku jirtaa isku dhafka kiimikada ee aluminium oxide (Al2O3). Waxaa ka mid ah darajooyinka dhoobada kala duwan, 96% Alumina Ceramic Circuit Board waxay ku dhufataa dheelitirnaan wanaagsan oo u dhexeeya waxtarka-wax-ku-oolnimada iyo sifooyinka waxqabadka sare. Waxay bixisaa dabci heerkul sare oo aad u sarreeya marka la barbar dhigo beddelka ku saleysan polymer iyadoo la ilaalinayo xoogga tamarta korontada ee aad u wanaagsan. Tani waxay ka dhigaysaa mid ku habboon codsiyada halka kulaylku uu muhiim u yahay, sida qaybaha korantada, nalalka LED-ka, iyo elektiroonigga baabuurta. Si ka duwan looxyada caadiga ah ee laga yaabo inay ku rogman karaan ama hoos u dhacaan cadaadiska kulaylka, ceramics alumina waxay bixiyaan xasillooni cabbir ah xitaa heerkulka sare, hubinta waxqabadka koronto ee joogtada ah waqti ka dib.
Intaa waxaa dheer, habka wax-soo-saarku wuxuu ku lug leeyahay farsamooyin saxan oo sax ah oo abuuraya qaab cufan oo aan dalool lahayn. Sharaftan qaabdhismeedku waxa ay ka hortagtaa nuugista qoyaanka, taas oo ah hab guuldarada guud ee deegaanka qoyan. Adoo dooranaya Alumina Ceramic Circuit Board, soosaarayaashu waxay wanaajin karaan celceliska wakhtiga u dhexeeya guuldarrooyinka (MTBF) ee alaabtooda, si ay u yareeyaan sheegashada dammaanadda iyo wanaajinta sumcadda sumadda. Iska caabbinta maaddadu u leedahay daxalka iyo kiimikooyinka ayaa sii ballaadhinaysa ku-dhaqankeeda guud ahaan qaybaha warshadaha iyo hawada.
Tilmaamaha Muhiimka ah iyo Faa'iidooyinka Farsamada
Marka la qiimeeyo xulashooyinka substrate-ka, astaamo kala duwan ayaa dhigaya Guddiga Wareegga Ceramic Alumina marka laga reebo tartamayaasha. Ugu horrayn waa dabaysha kulaylka, kaas oo caadi ahaan u dhexeeya 20 ilaa 25 W/m·K 96% darajooyinka daahirsanaanta. Tani waxay u oggolaanaysaa kuleyl hufan oo ka fog qaybaha xasaasiga ah, ka hortagga kulaylka iyo waxyeellada iman karta. Marka labaad, joogteynta dielectric ee aluminiumku waa mid deggan oo dhan kala duwanaansho badan oo soo noqnoqda, taas oo ka dhigaysa mid ku habboon gudbinta calaamadaha-sare ee iyada oo aan khasaare weyn ama qalloocin. Hantidani waxay muhiim u tahay codsiyada RF iyo wareegyada dhijitaalka ah ee xawaaraha sare leh.
Muuqaal kale oo muhiim ah ayaa ah isku-xirnaanta balaadhinta kulaylka (CTE). Qalabka CTE ee Alumina Ceramic Circuit Alaabooyinka waxaa lagu habayn karaa si ay ugu dhigmaan chips silikoon ama agabka kale ee semiconductor. Isbarbardhiggani wuxuu yareynayaa diiqada farsamada inta lagu jiro baaskiil wadida kulaylka, iyadoo yareyneysa khatarta delamination ama dildilaaca. Intaa waxaa dheer, qallafsanaanta dusha sare ee alumina waxay bixisaa iska caabin aad u fiican, taas oo u oggolaanaysa in si toos ah loogu dhejiyo qaybaha iyada oo aan lahayn dahaar ilaalin ah oo caqabad ku ah waxqabadka kulaylka. Mashruucyada u baahan tirinta joomatariyada gaarka ah ama lakabka, Adeegyada Nakhshadeynta Guddiga Wareegga Alumina Alumina waxay hubisaa in faa'iidooyinkan farsamo si buuxda looga faa'iidaysto si ay ula kulmaan shuruudaha injineernimada gaarka ah.
Tilmaamaha Alaabta oo faahfaahsan iyo Tixgelinta Nakhshadeynta
Fahamka waxyaabaha gaarka ah ee 96% Alumina Ceramic Circuit dhismaha waxay muhiim u tahay hirgelinta guusha leh. Maaddada saldhigga ahi waxay ka kooban tahay ugu horreyntii alfa-fase alumina, taas oo gacan ka geysata xoogga farsamada iyo awoodda korantada. Raad-raacyada wax-qabadka waxa sida caadiga ah loo qaabeeyey iyadoo la isticmaalayo filim dhumuc weyn leh ama teknooloji-filim khafiif ah, iyadoo la isticmaalayo biraha sida qalinka, dahabka, ama naxaasta oo leh lakabyo xannibaad ah si looga hortago faafitaanka. Doorashada metallization waxay saamaysaa labadaba alxanka iyo isku halaynta muddada dheer ee guddiga.
Marka la eego Nakhshadeynta Guddiga Wareegga Alumina ee Custom, dabacsanaantu waa furaha. Injineerada ayaa qeexi kara dhumucyada kala duwan, cabbirrada daloolka, iyo balacyada raadraaca si ay u qaadaan raad-raacyada qaybaha kala duwan. Naqshado lakabyo badan ayaa suurtagal ah iyada oo loo marayo lakabka xaashida dhoobada shakhsi ahaaneed, taas oo awood u siinaysa dariiqyo adag oo meelo is haysta. Si kastaba ha ahaatee, sababtoo ah jajabnaanta alaabta dhoobada, maaraynta taxadar leh iyo farsamooyinka khaaska ah ee qodista ayaa loo baahan yahay inta lagu jiro kulanka. Fiisyada kulaylka waxaa lagu dari karaa si kor loogu qaado kulaylka dego, isku xidhka qaybaha sare ee kulaylka dhinaca hoose. Tixgelinta naqshadayntan waxay hubisaa in badeecada ugu dambeysa ay la kulanto heerarka warshadaha adag ee badbaadada iyo waxqabadka.
Xaaladaha Codsiga iyo Kiisaska Isticmaalka Warshadaha
Kala-duwanaanshaha xalalka Alumina Ceramic Circuit Board wuxuu ku baahsan yahay warshado badan. Qeybta baabuurta, waxaa si aad ah loogu isticmaalaa eng. Waxqabadka ayaa ka sarreeya kan Alumina Ceramic & High Purity Alumina Ceramic.
Waxqabadku kama hooseeyo kan dhoobada Zirconia & Aluminium Nitride ceramic.
