6 mu Silicon Carbide 4H-SiC Semi-Insulating Ingot, Dummy Grade

Kufotokozera Kwachidule:

Silicon Carbide (SiC) ikusintha makampani opanga ma semiconductor, makamaka amphamvu kwambiri, ma frequency apamwamba, komanso osamva ma radiation. Ingot ya 6-inch 4H-SiC semi-insulating ingot, yoperekedwa mu kalasi ya dummy, ndi chinthu chofunikira popanga ma prototyping, kafukufuku, ndi ma calibration. Ndi bandeji yayikulu, matenthedwe abwino kwambiri, komanso kulimba kwamakina, ingot iyi imagwira ntchito ngati njira yotsika mtengo poyesa ndikukhathamiritsa popanda kusokoneza mtundu wofunikira wofunikira pachitukuko chapamwamba. Chogulitsachi chimagwira ntchito zosiyanasiyana, kuphatikizapo zamagetsi zamagetsi, zipangizo zama radio-frequency (RF), ndi ma optoelectronics, zomwe zimapangitsa kuti zikhale chida chamtengo wapatali pamakampani ndi mabungwe ofufuza.

Kusinthasintha:
Ndiwoyenera kumafakitale angapo, kuchokera kumakina amagetsi kupita ku kulumikizana ndi ma optoelectronics.

Mapeto

6-inch Silicon Carbide (4H-SiC) semi-insulating ingot, dummy grade, imapereka nsanja yodalirika komanso yosunthika ya kafukufuku, prototyping, ndi kuyesa m'magawo aukadaulo apamwamba. Matenthedwe ake apadera, magetsi, ndi makina amakina, kuphatikiza kukwanitsa komanso kusinthika mwamakonda, zimapangitsa kukhala chinthu chofunikira kwambiri kwa ophunzira ndi mafakitale. Kuchokera pamagetsi amagetsi kupita ku makina a RF ndi zida zowumitsidwa ndi ma radiation, ingot iyi imathandizira zatsopano pagawo lililonse lachitukuko.
Kuti mudziwe zambiri kapena kufunsa mtengo wamtengo wapatali, chonde titumizireni mwachindunji. Gulu lathu laukadaulo ndilokonzeka kukuthandizani ndi mayankho ogwirizana kuti akwaniritse zomwe mukufuna.
