NonconventionalSpecial Materials1

FAAMATALAGA PUPUU:
O le lelei o le alumini alumini o lona mamafa mama, malosi malosi, ma le faigofie e mafai ona faʻaogaina.E pei o lea e faʻaaogaina lautele i le gaosiga o mea faʻapipiʻi eletise.

VAEGA AUTU:
Fa'avevela vevela maualuga
•Maualalo le mamafa
• lelei platability ma workability, uaea tipi, olo ma luga auro e mafai ona faia.

Alumini Silicon uamea afifi

Aluminum Silicon Metal Packages

FAAMATALAGA PUPUU:
Si/Al alloys mo afifi faaeletonika e masani lava ona faasino i eutectic mea u'amea fa'atasi ma le silicon anotusi o le 11% i le 70%.O lona mamafa e maualalo, o le coefficient o le faʻalauteleina o le vevela e mafai ona faʻafetaui i le pu ma le substrate, ma o lona gafatia e faʻaumatia le vevela e sili ona lelei.O lona fa'atinoga o masini e lelei fo'i.O le iʻuga, e tele naua mea e mafai ona faʻaogaina e le Si / Al alloys i totonu o pisinisi faʻapipiʻi eletise.

VAEGA AUTU:
• Vave vevela dissipation ma conductivity vevela maualuga e mafai ona foia faafitauli dissipation vevela o loʻo iai i le atinaʻeina o masini maualuga.
• E mafai ona fa'atonutonuina le fa'aopoopoina o le fa'alauteleina o le vevela, lea e mafai ai ona fa'atusaina le pu, aloese mai le mamafa tele o le vevela e mafua ai le fa'aletonu o masini.
•Maualalo le mamafa

Taimane / Kopa, Taimane / Alumini

DiamondCopper, DiamondAluminum

FAAMATALAGA PUPUU:
Taimane / Kopa ma Taimane / Alumini o mea tuʻufaʻatasia ma taimane e avea ma vaega faʻamalosia ma kopa poʻo alumini e fai ma mea faʻamaʻi.O mea ia e matua'i fa'atauva ma fa'amanino mea fa'apipi'i fa'aeletoroni.Mo taimane / kopa ma taimane / alumini uamea fale, o le conductivity vevela o le eria chip o ≥500W / (m • K) -1, faʻamalieina manaʻoga faʻatinoga o le vevela maualuga dissipation o le matagaluega.Faatasi ai ma le faʻaauauina o le faʻalauteleina o suʻesuʻega, o nei ituaiga fale o le a faʻateleina le taua i le tulaga o le afifiina eletise.

VAEGA AUTU:
• Maualuluga le vevela
• O le coefficient o le faalauteleina vevela (CTE) e mafai ona pulea e ala i le suia o le vaega vaega tele o le taimane ma mea Cu.
•Maualalo le mamafa
• lelei platability ma workability, uaea tipi, olo ma luga auro e mafai ona faia

AlN mea'ai

AlN substrate

FAAMATALAGA PUPUU:
Aluminium nitride ceramic o se mea faʻapitoa faʻapitoa.E sili atu le vevela, masini ma eletise, e pei o le maualuga o le eletise eletise, o se faʻamaufaʻailogaina o le dielectric, o le faʻalauteleina o le faʻalauteleina o le silicon e fetaui ma le silicon, faʻapipiʻi eletise lelei, ma le maualalo.E le oona ma malosi.Faʻatasi ai ma le faʻalauteleina o le atinaʻeina o masini microelectronic, alumini nitride ceramics o se mea faʻavae poʻo mo le fale o le afifi, ua faʻateleina le lauiloa.Ose mea fa'akomepiuta fa'atasi ma mea fa'apipi'i lelei.

VAEGA AUTU:
• Maualuluga le fa'avevelaina o le vevela (e tusa ma le 270W/m•K), latalata ile BeO ma le SiC, ma sili atu ile 5 taimi ole Al2O3
•O le fa'amama fa'alautele fa'atasi e fetaui ma Si ma GaAs
• Lelei mea tau eletise (faila'i laiti dielectric tumau, dielectric gau, voluma tetee, dielectric malosi)
• Malosi fa'ainisinia maualuga ma fa'atinoga lelei o masini
• uiga lelei opitika ma microwave
