Ukusetshenziswa kwe-alumina substrate embonini yezimoto

I-Alumina (Al2o3) Substrate okwamanje iyindawo esetshenziswa kabanzi, i-ceramic subsstrate impahla esebenzayo kakhulu. Inikeza ukufakwa okuhle kukagesi, ukuqina kwamakhemikhali, ukuqhutshwa okuphezulu okushisayo, imvamisa ephezulu kanye nokunye ukusebenza okuhle okuphelele. Emkhakheni wemboni ezenzakalelayo, isidingo sabasekeli be-Alumina Ceramic besilokhu sanda unyaka nonyaka ngenxa yokuthuthuka okusheshayo komkhakha.

1. Ukusetshenziswa kwe-alumina ceramic substrate embonini yezimoto

1.1 Igbt Packing

I-IGBT ingenye yezinhlelo zokusebenza ezivelele kumadivayisi wesimanje kagesi, futhi aphesheya wamukelwa njenge Iningi lomkhiqizo omele uguquko lwesithathu lobuchwepheshe bamandla kagesi. I-IGBT iyithuluzi eliyisisekelo lokuguqulwa kwamandla nokudluliswa kwamandla, okungaguqula i-voltage, yamanje, imvamisa, isigaba, njll. Esisekelweni ngokuya ngezilawuli zezimoto, i-Vehive Air Conditioners. Kumamojuli we-IGCT wendabuko, ukucacisa i-alumina ceramic substrate yi-substrate esetshenziswa kakhulu kuyo yonke indawo. Kodwa-ke, ngenxa yokuvuselelwa okuphansi okuphansi kwe-Al2o3 Ceramic Substrate kanye nomdlalo ongemuhle nge-coefficie ye-silicon, ayilungele izinto zokupakisha zemodyuli ephezulu.

1.2 Iphakheji ye-Sensor Chip

Izinzwa zezimoto zidinga ukuthi izingxenye zizosetshenziswa endaweni enokhahlo ( (izinga lokushisa eliphakeme, ukudlidliza, ukushesha, umswakama, igesi, igesi, igesi, igesi, igesi ephelayo) ihlukile , amandla abukhali amahle, kanye nobubanzi obubanzi bokukhipha. I-Aluminium oxide ceramic substrate ingabekezelela ngokuphelele izinga lokushisa eliphakeme , ukuthuthuka, okuminyezwayo kanye nenqubekela phambili ye-accound technology isetshenziswe ngokuphelele, izinzwa e-alumina Izinto ze-Ceramic zingahlangabezana ngokugcwele lezi zidingo ezingenhla, ezimele ukusetshenziswa kwe-lidar, ikhamera, millimeter wave radar nokunye.

1.3 Ukupakishwa kwe-LED

Eminyakeni yamuva nje, ubuchwepheshe bokukhanyisa be-LED busetshenziselwe ukukhiqiza izimoto, njengezibani, ama-taillights, izinkomba, amalambu emkhathini, ukukhombisa ukubonwa emuva. Amandla aphezulu we-LED, ukunakekelwa okuthe xaxa kudinga ukuthi kukhokhwe inkinga yalo yokuhlanza ukushisa - Uma ukushisa okukhiqizwe umsebenzi we-LED akunakusakazwa ngempumelelo, kuzoholela ekushiseni kwe-LED junction kuphezulu kakhulu, akuholeli ku Ukuwohloka okusheshayo kokusebenza kahle okukhanyayo okukhanyayo, kodwa futhi nokuphila kwedivayisi ye-LED. Njengamanje, ukusetshenziswa kwe-alumina ceramic substrate akukhona nje izindleko eziphansi, kepha futhi kungakhiqiza kahle nangokwemvelo ukukhiqizwa kwamandla aphezulu, ukunemba okuphansi, ukunamathela okuphezulu, indawo ephezulu, indawo ephakeme ye-LED Ceramic Cooling Substrate, ngakho-ke ibilokhu igcwele isetshenziswe enkundleni ye-LED.

2. Amaphoyinti wekhwalithi we-alumina ceramic substrate

Yize u-Alumina ceramics angahlangabezana nezidingo ezisekelayo kanye nomsebenzi wokumelana nokuguguleka kwemvelo, Ukuvuselelwa kwangempela kanye nokwangempela okushisayo kuphansi, ukuthuthukisa ikhwalithi yomkhiqizo we-substrate kuyadingeka ukuze uhlangabezane kangcono nezidingo zokuthuthukiswa komkhakha we-elekthronikhi , Lungiselela ikhwalithi ye-Ikhwalithi Engavuthiwe ye-Al2o3 Powder, ukuthuthukisa inani lezakhiwo, kanye nokukhetha inqubo yokukhiqiza izikhundla zokuqala kwamukelwa .

2.1 Ukulungiselela Okubonakalayo Okubonakalayo

Ngokucwaninga kwesikhathi eside kanye nezicelo zokukhiqiza, ukuhlanzeka kwe-Al2o3, okuqukethwe kwe-α-isigaba, ukusatshalaliswa kosayizi wezinhlayiya nezinye izinkomba zinomthelela omuhle kwikhwalithi yemikhiqizo engezansi. Ngakho-ke, izidingo ezijwayelekile yilezi:
● Okuqukethwe kwe-NA2O kungaphansi kwe-0,1%, kunciphisa i-FE, FE2O, H2O okuqukethwe;
● I-morphology elungile yekristalu ukuze ibe yimodeli;
● Ukuguqulwa kwesigaba kwe-Alumina eluhlaza kufanele kulawulwe ngokufanele futhi kugcinwe kuzinzile;
● I-Alumina kufanele ibe yindawo egcwele ukunciphisa izinhlayiya ezinobungane.

2.2 Inqubo Yokukhiqiza

Ngaphezu kokukhethwa kwezinto zokwakha ezivuthiwe, inqubo eyakhekayo neyokwehla nayo iyinto ebalulekile ekunqumeni impumelelo noma ukwehluleka. Ngobuchwepheshe bokubumba, ukubumba kokujola, ukubumba kwabezindaba owomile nokubumba kuvame ukusetshenziswa, kepha ukusebenza kahle kokubumba okuphezulu kuphezulu, kepha kunzima ukwenza iphepha elikhulu; Ubuningi bomkhiqizo wokucindezela owomile buphezulu, iflethi ye-substrate kulula ukuyiqinisekisa, kepha ukusebenza kahle kokukhiqiza kuphansi, izindleko ziphezulu, kanye nokulungiswa kwe-Ultra-Fight Substrate kunzima. I-Casting yinzuzo ephindwe kabili yokusebenza kahle kokukhiqizwa okuphezulu kanye ne-Ultra-mncane, kepha kulula ukuyisebenzisa ngesikhathi sokwehla ngenxa yobudala obuphansi be-billet. Ngakho-ke, ukuze uthuthukise izinga lemikhiqizo emihle kakhulu yama-substrates amakhulu, imboni igxile ekusebenzeni kwezindlela ezine-potter kanye nokukhethwa kwezithasiselo zesono.
