Xirmooyinka Alloy aluminium

NonconventionalSpecial Materials1

SHARAXA GAABAN:
Faa'iidooyinka aluminium aluminiumku waa miisaankiisa fudud, xooggiisa adag, iyo si sahlan oo loo qaabeyn karo.Sidan oo kale waxaa si weyn loogu isticmaalaa soo saarista baakadaha elektiroonigga ah.

MEESHA ugu waaweyn:
Dhaqdhaqaaqa kulaylka sare
• Cufnaanta hoose
• Meelaynta wanaagsan iyo karti-shaqaynta, goynta siliga, shiididda iyo dahaadhka dahabka oogada sare waa la samayn karaa.

Xirmooyinka Birta Silikon Aluminium

Aluminum Silicon Metal Packages

SHARAXA GAABAN:
Si/Al Alloys ee baakadaha elektiroonigga ah inta badan waxay tixraacaan agabka daawaha eutectic oo leh maaddo silikoon ah 11% ilaa 70%.Cufnaantiisu way yar tahay, isku-dheellitirka balaadhinta kulaylka waxay la mid noqon kartaa chip-ka iyo substrate-ka, iyo awoodda ay ku baabi'inayso kulaylku waa mid aad u fiican.Waxqabadkeeda mashiinka ayaa sidoo kale ku habboon.Natiijo ahaan, Si/Al alloys waxay leeyihiin karti aad u weyn warshadaha baakadaha elektiroonigga ah.

MEESHA ugu waaweyn:
• Kuleylka degdega ah iyo kuleylka kuleylka sarreeya ayaa xallin kara dhibaatooyinka kuleylka kuleylka ee ku jira horumarinta qalabka awoodda sare leh.
• Isku-xidhka balaadhinta kulaylku waa la kontarooli karaa, taas oo suurtogal ka dhigaysa in la is waafajiyo ta chip-ka, iyada oo laga fogaanayo culayska kulaylka ee xad-dhaafka ah ee sababi kara cilladda aaladda.
• Cufnaanta hoose

Dheeman/Naxaas, Dheeman/Aluminium

DiamondCopper, DiamondAluminum

SHARAXA GAABAN:
Dheemanka/Naxaasta iyo Dheemman/Aluminiumku waa walxo isku dhafan oo leh dheeman oo ah wejiga xoojinta iyo naxaasta ama aluminiumka oo ah walxaha matrixka.Kuwani waa qalab elektaroonik ah oo tartan iyo rajo leh.Labada dheeman / naxaasta iyo dheeman / aluminium guryaha birta ah, kuleylka kuleylka ee aagga chip waa ≥500W / (m•K) -1, qancinta shuruudaha waxqabadka ee kuleylka sare ee wareegga wareegga.Iyada oo balaadhinta joogtada ah ee cilmi-baarista, noocyada guryeynta ayaa ka ciyaari doona door muhiim ah oo sii kordheysa oo ku saabsan baakadaha elektiroonigga ah.

MEESHA ugu waaweyn:
• Dhaqdhaqaaqa kulaylka sareeyo
Isku-dhafka balaadhinta kulaylka (CTE) waxaa lagu xakameyn karaa iyadoo la beddelo jajabka tirada dheemanka iyo walxaha Cu.
• Cufnaanta hoose
• Meelaynta wanaagsan iyo karti-shaqaynta, goynta siliga, shiididda iyo dahaadhka dahabka oogada ayaa la fulin karaa

Substrate AlN

AlN substrate

SHARAXA GAABAN:
Aluminium nitride ceramic waa qalab dhoobo ah oo farsamo.Waxay leedahay kuleyl aad u fiican, qalab farsamo iyo koronto, sida korantada sare ee korantada, joogitaanka dielectric yar oo qaraabo ah, iskudar fidin toosan oo siman silikon, dahaar koronto oo heer sare ah, iyo cufnaanta hoose.Ma aha sun iyo xoog.Iyada oo horumarinta baahsan ee aaladaha microelectronic, aluminium nitride ceramics sida maadada aasaasiga ah ama guryaha xirmooyinka, ayaa noqday mid caan ah.Waa wax baakad ah oo isku dhafan oo awood sare leh oo rajo leh.

MEESHA ugu waaweyn:
• Dhaqdhaqaaqa kulaylka sare (qiyaastii 270W/m•K), una dhaw BeO iyo SiC, iyo in ka badan 5 jeer Al2O3
•Iskudarka balaadhinta kulaylka waxay la mid tahay Si iyo GaAs
• Sifooyin koronto oo heersare ah (marka loo eego joogteynta dielectric yar, lumin koronto, caabbinta mugga, xoogga dielectric)
•Awoodda farsamada sare iyo waxqabadka mashiinada ku haboon
• Tilmaamaha indhaha iyo mikrowave ee ku habboon
•Aan sun ahayn
