Tsarin DBC na DBC Cermate tsari shine ƙara abubuwan oxygen tsakanin tagulla da ganiya, don samun ruwa mai tsaka-tsaki (Cualo2 ko Cuue2o4), don tabbatar da haɗuwa On Plate da yumbu substrate metallurgy metallurgy, kuma a karshe ta hanyar fasahar lithiphy don samar da tsarin tsari, samar da da'irar.
An rarraba PCB na yumbu zuwa yadudduka 3, da kuma insulating kayan a tsakiya shine Al2o3 ko AlN. Matsayi na Thermal na Al2O3 yawanci 24 w / (M.), Da kuma aikata thereral zartar da AlN AlN shine 170 w / (Mon). Mafi yawan amfani da fadada yanayin sararin samaniya na DBC substrate ya yi kama da na Al2O3 / AlN, wanda yake kusa da yawan zafin tasirin da aka samar da shi tsakanin guntu da blank yumbu substrate.
Fimit :
Saboda zare na tagulla yana da kyakkyawar hanya da wutar lantarki da kuma alumina na iya sarrafa rikicewar CU-Al2o3-CU sosai, saboda haka, DBC yana da fa'idodi na nagarta Yin aiki da hasken wuta, rufi mai ƙarfi da babban dogaro, kuma an yi amfani dashi sosai a cikin IGBT, LD da CPV iyawar CPV. Musamman saboda saboda tsananin farin ƙarfe (100 ~ 600μm), yana da bayyane fa'idodi a fagen IGBT da LD cocaging.
Rashin isasshen :
(1) Tsarin shirye-shiryen yana amfani da amsawa tsakanin CU da Al2o3 a babban zazzabi (1065 ° C), wanda ke buƙatar babban kayan aiki da sarrafawa, yana buƙatar farashin substrate sosai;
(2) Saboda saukin ƙarni na microvores tsakanin Al2o3 da Cuamers, abin saukarwa na Thermal juriya na samfurin an rage, kuma waɗannan kasawa sun zama bublelenck na cigaban DBC.
A cikin shirin aiwatar da DBC, zazzabi mai amfani da outctgen da bukatar a sarrafa shi sosai, da kuma iskar shaye-shaye da iskar shaka da iskar shaka da yawancinsu muhimman sigogi biyu ne. Bayan fage zare shine pre-oxidized, boda keɓewa na iya samar da isasshen lokacin cuxoy zuwa rigar Al2o3, tare da zare mai ƙarfi, tare da ƙarfi mai ƙarfi; Idan katako na jan ƙarfe ba shi ne precidized, Cuxoy Wethezy shine talauci, kuma babban ramuka da lahani zai ci gaba da kula da batun ba, yana rage ƙarfi da kuma halayen da aka yi. Don shirye-shiryen DBC substires ta amfani da Aln naircircations, shi ma wajibi ne don preil ox outectic saƙo don Eutectic dauki.
