Zvigadzirwa uye hunhu hweCeramic Substrates

Nekufambira mberi uye kusimudzira kwehunyanzvi, iyo yekushandisa yazvino, tembiricha yekudziya uye inofambiswa mumidziyo yave ichikwira zvishoma nezvishoma. Kuti tisangane nekuvimbika kwemidziyo nematunhu, zvakakwirira zvinodiwa zvakaiswa kumberi kwechipatakuri. Ceramic Severates inoshandiswa zvakanyanya muminda iyi nekuda kwezvinhu zvavo zvakanakisa zvekunze, microwave zvivakwa, zvivakwa zvemakaniki uye kuvimbika kwakanyanya.

Parizvino, mainini eCeramic zvinhu zvinoshandiswa muCeramic Simberrate ari: Alumini (Aluminium Nitride (Aln )

Ngatione humbowo hupfupi hweaya mashanu ezvikamu zvezvakakura zveCeterates seinotevera:

1. Alumina (Al2o3)

Al2o3 Homogeus polycrystals inogona kusvika anopfuura marudzi anopfuura gumi, uye marudzi makuru ekristaro ari seyinotevera: α-al2o3, β-al2o3, γ-al2o3 uye zt-al2o3. Pakati pavo, α-al2o3 ine yakaderera basa uye ndiyo yakanyanya kugadzikana pakati pemhando ina dzekristaro mafomu, uye sero rayo renyunivhesiti rakanongedzerwa, ndege yeHexagonal Crystal system. α-al2o3 chimiro chakasimba, corundum chimiro, chinogona kuvapo zvachose pakupisa kwese; Kana tembiricha ichisvika 1000 ~ 1600 ° C, vamwe vanosiyana havachinjiki vanoshandura kuva α-al2o3.

Mufananidzo 1: Crystal Microstruture yeAl2o3 pasi peSEM

Nekuwedzera kweAl2o3 misa chidimbu uye kuderera kwegirazi chikamu cheGirazi, iyo maCererain's Cermics inosvika 99%, yayo inobata 90%.

Kunyangwe ichiwedzera chikamu chakawanda cheAl2o3 chinogona kuvandudza mashandisiro ezvekuita kweCeramics, inowedzerawo kupisa kwemakiridzi weCeramics, ayo zvisina kunanga anotungamira mukuwedzera kwemari yekugadzira.

2. Aluminium Nitride (Aln)

Aln rudzi rweboka racho Dero rayo razvino riri Aln4 tetrahedron, ndezvemichero yeHexagonal system uye ine chisungo chakasimba chovanhu, saka chine mashandiro akanaka emuchina uye simba rakanyanya kukotama. Theoretally, denderedzwa density its 3.2611G / cm3, saka ine yakanyanya kufambidzana ne23w / (m) kutembera kwemakamuri, uye iyo inovhara yekupisa kweiyo inopisa-yakadzvanywa yakadzvanywa Aln Substrate inogona kusvika 150W / (m kor), iyo inodarika mashanu nguva iyo yeAL2O3. Iyo inowedzera yekuwedzera ndeye 3.8 × 10-6 ~ 4.4

Aln ceramics ine yakakwira inobata Aln ceramics inofungidzirwa zvakare seyakavimbika zvinhu zveSimba rekutumira hwindo reWindows vacuum zvigadzirwa nekuda kwesimba ravo rekisimusi Electron.

3. Silicon Nitride (Si3n4)

Si3n4 is a covally yakasungwa compound ine matatu makristaro zvivakwa: α-si3n4, β-si3n4, uye γ-si3n4. Pakati pavo, α-si3n4 uye β-si3n4 ndiyo yakajairwa makristaro mafomu, ine hecaronga chimiro. Iyo inobata yekubatanidza kweiyo imwe crystal si3n4 inogona kusvika 400W / (m). Nekudaro, nekuda kwekutamisa kwayo phonon . Nekutsvagisa chikamu chemuchato uye chinonamira maitiro, iyo yekubatanidza inosvika 106w / (m). Iyo inowedzera yekuwedzera inoenderana ne si3n4 ndeye 3,0 × 10-6 / C.S.CE SIADS, kugadzira Si3n4 ceramic Substrate Chinyorwa cheKukoshwa magetsi magetsi magetsi magetsi magetsi.

Mufananidzo 3: Poda yeSilicon Nitride

Pakati peiyo iripo cramic substrates, si3n4 ceramic svivi inoonekwa seyakanakisa zvinhu zvakakura, kudzika kwakanyanya, kuparadzwa kwakanyanya Parizvino, inofarirwa mu Igbt module packaging uye zvishoma nezvishoma inotsiva al2o3 uye aln ceramic sissetrates.

4..liconon carbide (Sic)

Single Crystal SIC inozivikanwa seyechitatu yechizvarwa cheMeiconductor zvinhu, icho chine zvakanakira bhendi hombe yebhendi, yakakwira kuputsa voltage, yakakwirira yekuvhara kubatana uye yakakwirira emagetsi ekufambisa.

Nekuwedzera shoma shoma Iyo inovharidzira yeSIC ceramics ine kwakasiyana kuchena yakagadzirirwa nenzira dzakasiyana dzekuchenjera uye dzekuwedzera ndeye 100 ~ 490w / (m) pamhepo tembiricha. Nekuti iyo dielectric inogara ichisvika ceramics yakakura kwazvo, zvakangoerekana zvakakodzera kuti zviwedzere-frequency-frequency zvikumbiro, uye hazvina kukodzera kune yakakwirira-frequency application.

5. Beryllia (BEO)

Icho bhebhi ndeyekuti urtzite chimiro uye sero ndiCubic Crystal system. Kubata kwaro kunhuhwirira kwakanyanya Haisi chete yakanyanya kupisa kupisa simba, asi zvakare ine yakaderera dielectric yekuchengetedza uye dielectric kurasikirwa uye yakakwira midziyo yekunyorwa mune yakasarudzika zvishandiso-mashandiro ezvematunhu ekunyanyisa.

Mufananidzo 5: Crystal chimiro cheBerllia

Iyo yakakwira inovharidzira kubatana uye yakaderera kurasikirwa kweiyo belo yakanyanya kusarongeka nezvimwe zvinhu zvekunongedza, asi ido ine zvikanganiso zviri pachena, uye hupfu hwayo hune chepfu.

Parizvino, iyo inowanzoshandiswa seyakagadzirwa substrate zvinhu muChina inonyanya kuve al2o3, Aln naSi3n4. Iyo ceramic substrate yakagadzirwa neLTCC tekinoroji inogona kubatanidza zvikamu zvevanoita seanonunura, capacitors uye inodzivirira mune matatu-matatu emhando chimiro. Mukupesana nekubatanidzwa kweMeneMiconductres, ayo anonyanya kuita zvishandiso, LTCC ane yakakwirira-density 3d insitoking wiring yekugona kurova.
