Tushen zafi yumbu na'ura ce da ke watsar da zafi daga abubuwan lantarki masu saurin zafi na kayan lantarki.A halin yanzu, da aka saba amfani da alumina yumbu takardar, aluminum nitride yumbu takardar, silicon carbide yumbu takardar.

Alumina yumbu sheet: Yana da babban haɓakar thermal, haɓakar thermal: 24W / MK, babban zafin jiki / juriya mai ƙarfi, zafi a ko'ina, saurin zafi mai zafi.Bugu da ƙari, yana da sauƙi da ƙananan tsari, ƙananan ƙananan, m surface, babban ƙarfi kuma ba sauki karya, acid da alkali lalata juriya, m.

Aluminum nitride yumbu sheet: Launi yana da launin toka mai launin toka, shimfidar wuri mai santsi, ana iya daidaita shi zuwa kowane nau'i ko girman, sauƙin amfani da shigarwa.Wannan yumbu radiyo yana da matukar high thermal watsin, da thermal watsin ne 7-10 sau na alumina yumbu takardar, iya isa 180W high, ta lantarki rufi yi sosai barga, dielectric akai-akai da matsakaici asara ne low, iya jure 1800 digiri Celsius kuma baya shafar aikin samfurin.Tare da saurin haɓaka kayan aikin lantarki, buƙatun samfuran lantarki ko kayan taimako shima yana ƙaruwa, kuma ƙimar aikace-aikacen wannan samfurin a matsayin babban madaidaicin zafin jiki na aluminum nitride yumbu a matsayin matrix ko kayan tattarawa yana ƙara ƙaruwa sosai a kasuwa. .

Silicon carbide yumbu takarda: Yana da kayan kare muhalli na kore, yana cikin tsarin microporous, a cikin yanki guda ɗaya zai iya zama fiye da 30% porosity, yana ƙara yawan yanayin zafi da kuma hulɗar iska, haɓaka tasirin zafi.A lokaci guda kuma, ƙarfin zafi yana da ƙananan ƙananan, ajiyar zafi na kansa yana da ƙananan, ana iya canja wurin zafi zuwa duniyar waje da sauri, babban halayen yumbu mai zafi: kariya ta muhalli, kariya da kuma juriya mai girma, ingantaccen zafi mai zafi. , don kauce wa haifuwar matsalolin EMI.Zai iya magance matsalolin tafiyar da zafi da zafi a cikin kayan lantarki da na gida.A lokaci guda, yana da dacewa musamman don ƙarami da matsakaicin wutar lantarki.Wurin zane yana ba da hankali ga haske, bakin ciki, gajere da ƙananan samfurori, wanda zai iya ba da goyon bayan fasaha da aikace-aikace don haɓakawa da haɓaka kayan lantarki.
