I-Cerallized Cerafised-umhlahlandlela wokugcina wabaqalayo nesazi

Ukuqalisa

Le ndatshana ifaka inqubo yokukhiqiza yama-cerallics ama-cerallics, izinhlobo zezindlela ze-cerallized ceramic, izici ezithinta ubumba ama-cerallics, q ukuqinisekiswa kanye nohlelo lokusebenza lwayo , uzofunda imininingwane elandelayo:

ISAHLUKO 1: Yini M etallized c eramic s

I-ceramics ye-metallized ibhekisa engxenyeni yefilimu yensimbi ifakwa endaweni ethile ye-ceramics ye-ceramics yezobunjiniyela, bese iphiyela emkhathini wokunciphisa izinga lokushisa (i-hydrogen noma i-nitrogen), ukuze ifilimu lensimbi linamathisele phezulu ebusweni bezakhi ze-ceramic , bhekisa kuMfanekiso 1 .

Umdwebo 1: I-Cerallized Cerallic

Ngemuva kwenqubo yensimbi, ingaphezulu le-ceramic linikeza izici zensimbi, lingathola ukuxhumana okusebenzayo phakathi Ceramic nensimbi nge-brazing.

Isahluko 2: Kungani Ngabe i -ceramic s metalli zed ?

Njengezinto ezijwayelekile ze-Inorganic ezingezona zensimbi, ama-ceramics athuthukile asetshenziswe kabanzi kuma-voltage aphezulu aphezulu, amadivaysi aphezulu aphezulu aphezulu kanye ne-elekthronikhi, ama-semiconductor ama- semiconductor, amamojula we-iGBT ngenxa yobulukhuni babo obuhle, ngokomzimba kanye namakhemikhali Izakhiwo, izakhiwo zemishini, izakhiwo ezishisayo kanye nezakhiwo ze-Optical. Kulezi zivumelwano ezisebenzayo , kuvame ukubandakanya ukuhlangana kwama-ceramics nezingxenye zensimbi ezintweni ezihlukile, njengensimbi engenasici, ithusi elingenamimoya, i-kovar nokunye. Njengoba ukwanda kwe-thermal kokunwebeka kwezinto ezibonakalayo ze-ceramic kanye nensimbi kunomehluko omkhulu; okwamanje, lezi zinto ezimbili ngokwemvelo zinomphumela omubi wokumanzisa; Futhi kulezi zinkambu, indawo ebekelwe uphawu lezingxenye ze-ceramic nensimbi inamandla aqinile wokubekwa uphawu (amandla ashubile) nezidingo zomoya wokuqina ngemuva kokubhidliza, ngakho-ke azikwazi ukuxhunyaniswa ngqo. Kwazalwa ubuchwepheshe be-ceramic metallization.

Isahluko 3: Izakhiwo ze- M Etallized C Eramic

1. Ukusebenza okuphezulu okushisayo

Ukushisa okukhiqizwe yi-chip kungadlulisela ngqo ezingxenyeni zobumba ngaphandle kwesendlalelo sokufaka, okuholela ekuchithekeni okungcono kakhulu kokushisa.

2. I-coefficion ekahle yokunwebeka

I-coefficion ethe xaxa ye-ceramics athuthukile nama-chip iyafana , futhi ngeke kubangele ukwehlukana kakhulu lapho umehluko wokushisa ushintsha, okuholela ezinkingeni ezinjenge- Circuit de Soldering kanye nengcindezi yangaphakathi Esigabeni sokuxhumana .

3. I-dielectric ephansi njalo

I-dielectric njalo ye-ceramic ukwaziswa ngokwayo yenza ukulahleka kwesiginali kuncane, ngakho-ke izinto zokwakha ubuciko bezobuchwepheshe isetshenziswa kabanzi kwimishini yokuxhumana nokuhanjiswa kwesiginali.

4. I-High Bonding Force

Amandla aphezulu aphezulu we-Metal ungqimba kanye ne-ceramic substrate yemikhiqizo ye-Ceramic ye-Ceramic Board Board, kuze kufike ku-45mpa (enkulu kunezinqumo ezi-1mm eziwugqinsi ze-ceramic ngokwazo)

5. Ukushisa okuphezulu okuphezulu

C Eramics ingamelana nemijikelezo yokushisa ephezulu nephansi ngokushintshashintsha okukhulu, futhi ingasebenza ekushiseni okuphezulu kwamazinga angama-800 isikhathi eside.

6. Ukufakwa kukagesi okuphezulu

Ama-ceramics wezimboni ngokwawo azofaka izinto ezifakwayo ezingamelana nama-voltages aphezulu okuqhekeka, ikakhulukazi ama-ceramic insulators ngemuva kokukhazimula, futhi angafakwa ngisho nasemasimini anama-volitages ngenhla kwe-100KV.

7. Ukuqina kwamakhemikhali

Umzimba we-ceramic unokuqina okungcono kwamakhemikhali, futhi ngeke usabele nama-acid anamandla nezisekelo, futhi ngeke afakwe oxidised endaweni yokushisa ephezulu .

ISAHLUKO 4: M ECHANISM KANYE CHAMIC Metallization

Uyini umkhuba we-ceramic metallization? Indlela ye-ceramic metallization isebenzisa ukusabela okuhlukile kwamakhemikhali kanye nokufuduka okuhlukile kwezinto ezahlukahlukene kuma-ceramics athuthukile kanye nezingqimba zensimbi ezigabeni ezihlukene ze-sonse, ezinjenge-oxides ezingezona ezonkabi kanye no-nonmellic. Njengoba izinga lokushisa likhuphuka, kwakhiwa isigaba soketshezi lapho zonke izinto ziphendula ukwakha amakhompiyutha aphakathi futhi afinyelele iphuzu elijwayelekile lokuncibilika. Isigaba se-Liquid Glass sinokubonakala okuthile futhi kukhiqize ukugeleza kwepulasitiki ngasikhathi sinye. Ngemuva kwalokho, izinhlayiya zengilazi zihlelwe kabusha ngaphansi kwesenzo sama-capillaries, futhi ama-athomu noma ama-molecule asetshenziswa futhi athuthelwe ngaphansi kwedrayivu yamandla angaphezulu komhlaba. Ama-pores kancane ancipha futhi anyamalale ngokwanda kosayizi wokusanhlamvu, ngaleyo ndlela babone ukudingida kwesendlalelo sensimbi , bheka isibalo 2:
