Ceramic PCB: yumbu substrate kewaye allon

Ceramic Substrate yana kwatanta allon hanya na musamman inda foil ɗin aluminum na jan karfe ya manne kai tsaye zuwa yankin saman (gefen keɓe ko gefe biyu) na alumina (Al2O3) ko ƙaramin yumbu nitride (AlN) yumbu mai nauyi a zafi. Idan aka kwatanta da daidaitaccen FR-4 ko ƙaramin alumini mai nauyi mai nauyi, ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun ƙwararrun zazzaɓi, ingantaccen solderability na musamman da ƙarfin haɗin gwiwa, kuma ana iya zana hotuna da yawa kamar PCB, tare da dama data kasance lugging iyawa.

Me yasa ake amfani da kayan yumbu don samar da allon kewayawa? An yi allunan kewayen yumbu da yumbu na lantarki kuma ana iya yin su ta nau'i daban-daban. Halayen juriya na zafin jiki da kuma babban rufin wutar lantarki na allunan kewayen yumbu sune mafi shahara. Fa'idodin ƙarancin dielectric akai-akai da asarar dielectric, haɓakar haɓakar zafi mai ƙarfi, kwanciyar hankali mai kyau na sinadarai, da makamancin haɓakar haɓakar thermal zuwa abubuwan da aka haɗa su ma suna da mahimmanci. Samar da allunan da'ira na yumbu za su yi amfani da fasahar LAM, wanda shine fasahar sarrafa saurin kunna wutar lantarki ta Laser. Ana amfani da su a cikin filin LED, high-power semiconductor modules, semiconductor firiji, lantarki heaters, ikon iko da'irori, ikon matasan da'irori, kaifin baki ikon gyara, high-mita sauya wutar lantarki, m-jihar relays, mota lantarki, sadarwa, sararin samaniya, da kayan aikin lantarki na soja.

Babban abũbuwan amfãni:
Higher thermal watsin.
Ƙarin madaidaicin ƙimar faɗaɗawar thermal.
Ƙarfi da ƙananan juriya karfe fim alumina yumbu kewaye allon.
Solderability na substrate yana da kyau, kuma yawan zafin jiki na amfani yana da girma.
Kyakkyawan rufi.
Ƙananan hasara mai girma.
Babban taro mai yiwuwa.
Ba ya ƙunshi sinadarai na halitta, yana da juriya ga haskoki na sararin samaniya, yana da babban aminci a sararin samaniya, kuma yana da tsawon rayuwar sabis.
Tushen jan ƙarfe ba ya ƙunshi Layer oxide kuma ana iya amfani dashi na dogon lokaci a cikin yanayi mai ragewa. PCBs na yumbu na iya zama da amfani da inganci ga allon da'irar bugu a cikin waɗannan da sauran masana'antu da yawa, dangane da ƙira da buƙatun ku.

Ceramic PCB wani nau'in zafi ne da ke gudanar da yumbu foda da kuma ɗaure kwayoyin halitta, kuma ana shirya PCB ɗin yumbu mai zafi a yanayin zafi na 9-20W / m. A wasu kalmomi, yumbu PCB shine allon da'irar da aka buga tare da kayan tushe na yumbu, wanda shine kayan aikin thermal sosai kamar alumina, aluminum nitride, da beryllium oxide, wanda zai iya yin tasiri mai sauri akan canja wurin zafi daga wuraren zafi da watsawa. shi a kan dukan surface. Menene ƙari, yumbu PCB an ƙirƙira shi da fasahar LAM, wanda shine fasahar sarrafa saurin kunna laser. Don haka yumbu PCB yana da matuƙar dacewa wanda zai iya faruwa na gabaɗayan allon da'irar bugu na gargajiya tare da ƙarancin rikitarwa tare da ingantaccen aiki.

Baya ga  MCPCB , idan kana so ka yi amfani da PCB a high matsa lamba, high rufi, high mita, high zafin jiki, da kuma high abin dogara da kuma kananan girma lantarki kayayyakin, sa'an nan Ceramic PCB zai zama mafi kyau zabi.

Me yasa Ceramic PCB yana da irin wannan kyakkyawan aiki? Kuna iya samun taƙaitaccen ra'ayi game da ainihin tsarin sa sannan za ku fahimta.
