Traditional metal-core printed circuit boards (MCPCBs) ane high thermal resistance nekuda kweinodiwa polymer insulation layer pakati pesimbi necircuit layers, zvichiita kuti vawedzere kusakwanisa kusangana nezvinodiwa zvekubvisa kupisa kwesimba repamusoro-soro uye e-ultra-high-simba maLED. Kusiyana neizvi, ma substrates eceramic anosanganisa kusungirira uye kupisa kwekushisa, kubvisa kupindirana kwekupisa kupisa

Alumina izita rinowanzozivikanwa realuminium oxide (Al2O3). Iyo yakasimba tekinoroji ceramic ine yakasarudzika musanganiswa wemakanika uye magetsi maitiro. Inokodzera zvakasiyana-siyana zvekushandiswa kwemaindasitiri.

Boron nitride isimbi yakagadzirwa nekeramic inouya muupfu uye yakasimba fomu. Boron nitride chinhu chaicho chakasarudzika nekuda kwehunhu hwayo hwakakosha, hunosanganisira kupisa kwakanyanya, kusarudzika kupisa conductivity, kureruka kwemachining, lubricity, yakaderera dielectric kugara, uye yakawedzera dielectric simba.

Aluminium nitride chinhu chinobatsira mune akasiyana maindasitiri ekushandisa nekuda kwemakemikari ayo uye emuviri zvimiro.Nekudaro, mukugadzira, aluminium nitride inonyanya kupatsanurwa kuita mhando mbiri zvichienderana nekuita sintering: pressureless sintered aluminium nitride uye inopisa-yakadzvanywa aluminium nitride. Zvimiro uye mashandisirwo ezvikamu zviviri izvi zvinosiyana zvakanyanya.

Boron carbide ndechimwe chezvinhu zvakasimba uye zvakasimba zvakanyanya zviripo munzvimbo yanhasi, uko kushanda, kushanda zvakanaka, uye hupenyu hunokosha. Inonyatsozivikanwa nokuda kwekugadzikana kwayo kunoshamisa kwekushisa, kusagadzikana kwemakemikari, uye kushandiswa kwemari, uye yakaratidza kuva chinhu chinokosha mune zvakasiyana-siyana zvemabhizimisi, kusanganisira kugadzira nekudzivirira.

Mukati memhuri yeKovar, 4J29 ndiyo yakajairwa uye yakakurudzirwa zvinhu zvekubhuroka yakakwirira-alumina ceramics, ichipa mwero wakanaka wekuita, mutengo, uye kuvimbika. 4J33/34 kuvandudzwa kwekuita kune mamwe maapplication ayo anoda hukuru hwekushanda tembiricha kana kuomarara kusina magineti maitiro. Iyo brazing yeKovar ine alumina ceramics, iyo inotsigirwa ne therma yavo

Boron nitride poda ine hunhu hwakanakisa senge thermal conductivity, insulation, lubrication, high-temperature resistance, uye kugadzikana kwekemikari, zvichiita kuti ive chinhu chinochinjika chekubata nyaya dzakasiyana siyana pasi pemamiriro ekushanda zvakanyanya muindasitiri yemazuva ano.

Active metal brazing ndiyo yekutanga nzira yekugadzira inovimbika ceramic-to-metal junctions, ine helium mass spectrometer leak yekuona inoshanda seyegoridhe chiyero chekusimbisa hermeticity. Iko kusanganiswa kweaya matekinoroji maviri kunovimbisa kuvimbika kwenguva refu kwezvikamu zvakashongedzwa mumamiriro ezvinhu akaoma.

TiB2-BN-AlN composite conductive ceramic evaporation mabhoti anoshandiswa zvakanyanya muindasitiri yesimbi evaporation nekuda kwemabhenefiti eiyo composite zvinhu, iyo inosanganisa yakakwira kunyungudika, kusimba kwekemikari, kusimba kwepamusoro, yakanaka conductivity, uye yakanaka resistivity tembiricha coefficient yeTiB2, iyo magetsi ekudzivirira, yakanyungudutswa simbi corrosion resistance, yakanakisa inopisa shoc.

Kuenzaniswa neyechinyakare mumhepo kana kumanikidza-sintered alumina mabhora, ayo anogadzirwa achishandisa HIP maitiro anomiririra kusvetuka kwehunhu.
