Ukugxumela Okujulile Emabhodini Esekethe eCeramic: Izinzuzo, Izicelo, kanye Nokusungulwayo

Ngokungafani nozakwabo bendabuko abenziwe nge-fiberglass kanye ne-epoxy resin, amabhodi wesekethe se-ceramic enziwe ngezinto ze-ceramic eziqhuba kahle kakhulu futhi ezizinzile ngokokushisa. Ngokomlando, ukwamukelwa kwezinto ze-ceramic ekukhiqizweni kwebhodi yesekethe kwaphawula ushintsho olubalulekile embonini ye-elekthronikhi, kubhekana nezinselele ezibalulekile ezihlobene nokusebenza kwezinga lokushisa eliphezulu kanye nemvamisa ephezulu.

Le dive ejulile ihlose ukwambula izendlalelo zobuchwepheshe bebhodi lesifunda se-ceramic, igqamisa izinzuzo zayo kanye nobubanzi obumangalisayo bezinhlelo zayo zokusebenza.

Umlando Omfishane Wamabhodi Wesekhethi Ye-Ceramic

Ekuqaleni, ukusetshenziswa kwezitsha zobumba ku-elekthronikhi kwakukhawulelwe ezintweni zokufaka i-insulating nama-substrates ezingxenyeni ze-passive ezifana nama-capacitor nama-resistors. Kodwa-ke, izakhiwo zemvelo zezinto ze-ceramic, ezifana ne-thermal conductivity ephezulu, ukufakwa kukagesi okuhle kakhulu, namandla aqinile emishini, kwethule amandla angasetshenzisiwe okuguqula ubuchwepheshe bebhodi lesifunda.

Umqondo wokusebenzisa izinto ze-ceramic zamabhodi esekethe waqala ukuzulazula phakathi nekhulu lama-20, uqhutshwa isidingo sezimboni ze-aerospace kanye nezokuvikela sezingxenye ze-elekthronikhi ezingamelana nezimo ezimbi kakhulu. Le mikhakha idinga amadivaysi angasebenza ngokuthembekile lapho ebhekene nezinga lokushisa eliphezulu, ukucindezeleka kwemishini, kanye nezindawo ezibolayo, izinselele izinto ze-PCB zendabuko ezazilwela ukuhlangabezana nazo.

Esinye seziqophamlando ezibalulekile ekuthuthukisweni kwamabhodi esekethe e-ceramic kwaba ukuthuthukiswa kobuchwepheshe be-hybrid film hybrid ngeminyaka yawo-1960. Le nqubo ihilela ukunamathisela kokuphrinta kwesikrini, okuphikisayo, kanye ne-dielectric ku-substrate ye-ceramic, bese ibadubula emazingeni okushisa aphezulu ukuze yenze isekethe ye-elekthronikhi. Lokhu okusha kwavula amathuba amasha okuhlanganisa izingxenye eziningi kusisekelo esisodwa se-ceramic, okuholela ekwakhiweni kwamamojula we-elekthronikhi ahlangene, asebenza kahle kakhulu.

Njengoba ubuchwepheshe buthuthuka, ngeminyaka yawo-1980 kanye nawo-1990 kwethulwa ubuchwepheshe be-ceramic obushiswe ngokushisa okuphansi bezinga lokushisa eliphansi (LTCC) kanye nobuchwepheshe be-high-temperature co-fired ceramic (HTCC) . Lezi zindlela zavumela ukwakhiwa kwamabhodi wesifunda se-ceramic multilayer, okwandisa kakhulu ukuminyana kwesifunda nokusebenza. Ubuchwepheshe be-LTCC kanye ne-HTCC baba semqoka ekwenziweni okuncane kwezinto zikagesi, okuvumela ukuhlanganiswa kwamasekhethi ayinkimbinkimbi abe amaphakheji amancane ngaphandle kokuyekethisa ukwethembeka noma ukusebenza.

Onjiniyela bavame ukuqinisekisa lesi sihloko kanye nokubuyekezwa kwe-PCB kanye ne-DFM substrate ye-ceramic lapho belungiselela ukwakhiwa kwe-PCB noma i-PCBA okuthembekile.

Izinzuzo ZeCeramic Circuit Boards

I-High Heat Resistance kanye ne-Thermal Conductivity

Enye yezinzuzo eziyinhloko zamabhodi wesifunda se-ceramic yikhono lawo eliyingqayizivele lokumelana namazinga okushisa aphezulu. Ama-PCB endabuko angehlisa isithunzi noma ahluleke lapho evezwe kumazinga okushisa aphakeme, akhawulele ukusetshenziswa kwawo kuzinhlelo zokusebenza zamandla aphezulu noma izinga lokushisa eliphezulu. Ngakolunye uhlangothi, amabhodi esekethe e-Ceramic enziwe ngezinto ezifana ne-alumina, i-aluminium nitride, ne-beryllium oxide, ene-thermal conductivity ephezulu futhi ekwazi ukusebenza kahle emazingeni okushisa afika nangaphezu kuka-350 ° C. Lokhu kubenza bafanelekele ukusetshenziswa ezindaweni ezinzima ezifana ne-aerospace, izimoto, nemishini yezimboni, lapho ukwethembeka ngaphansi kwengcindezi yokushisa kubalulekile.

Ukuqina Okuthuthukisiwe Nokwethenjelwa

Amabhodi wesifunda se-Ceramic nawo ahamba phambili ngokuhlala nokuthembeka. Ngokungafani nama-PCB endabuko, athambekele ekumunceni umswakama kanye nokunwetshwa kokushisa, ama-substrates e-ceramic awasebenzi futhi azinzile, anikeza ukumelana okuhle kakhulu nokugqwala kwamakhemikhali, ukugqokwa kwemishini, kanye nokushaqeka okushisayo. Lokhu kuqina kwandisa isikhathi sokuphila sezinto zikagesi, kunciphisa isidingo sokushintshwa noma ukulungiswa, futhi kunikeza ukusebenza okungaguquki ngisho nasezimeni zokusebenza ezinzima.

Izinzuzo Zokusebenza Kagesi

Ngaphezu kwezinzuzo ezishisayo nezemishini, amabhodi wesifunda se-ceramic anikeza ukusebenza kukagesi okuphezulu. Izakhiwo ze-dielectric zezinto ze-ceramic zinika amandla ubuqotho besignali engcono kanye nokunciphisa ukuphazamiseka kwe-electromagnetic (EMI), okubalulekile ekusetshenzisweni kwamafrikhwensi aphezulu njengokuxhumana ngocingo kanye nekhompyutha ethuthukisiwe. Ngaphezu kwalokho, i-dielectric ephansi engaguquki kanye ne-tangent yokulahlekelwa ye-ceramic substrates isekela isivinini sokudlulisa isignali esheshayo, ithuthukisa ukusebenza kahle kanye nokusebenza kwezinto zikagesi.

Izicelo zeCeramic Circuit Boards

Umkhakha Wezindiza

Emkhakheni we-aerospace, ukwethembeka nokusebenza akuxoxiswana. Amabhodi esekethe e-Ceramic asetshenziswa kakhulu ngenxa yekhono lawo lokumelana nokuguquguquka okwedlulele kwezinga lokushisa nokudlidliza okuhlangatshezwana nazo ezinhlelweni ze-aerospace. I-thermal conductivity ephezulu kanye nokufaka ugesi okuhle kakhulu kuqinisekisa ukuthi izingxenye ze-elekthronikhi zingakwazi ukusinda ebunzimeni bendawo kanye nezindiza eziphakeme kakhulu, kusukela kumasistimu wesathelayithi kuya kuma-avionics ezindiza.

Izithuthi Zamagesi

Imboni yezimoto ibhekene nezinguquko, ngokugxila okukhulayo ezimotweni zikagesi (EVs) kanye nezinhlelo ezithuthukisiwe zokusiza abashayeli (ADAS). Amabhodi esekethe e-Ceramic asekela lokhu kuguquka ngokunikeza ukuqina nokumelana nokushisa okudingekayo kuma-electronics wezimoto. Zisetshenziswa kuziguquli zamandla, izinzwa, namayunithi okulawula, okuqinisekisa ukusebenza okuthembekile ezindaweni ezinokhahlo izimoto ezivame ukubhekana nazo.

Ukukhanyisa kwe-LED

Amabhodi wesifunda seCeramic abe yisisekelo embonini yokukhanyisa i-LED. Amandla azo aphakeme okukhipha ukushisa avumela izibani ze-LED ukuthi zisebenze kahle kakhulu nangesikhathi eside sokuphila. Lokhu kuzuzisa kakhulu ezinhlelweni ze-LED ezinamandla amakhulu, ezifana nezibani zasemgwaqweni kanye nezinhlelo zokukhanyisa ezentengiselwano, lapho ukugcinwa kwezinga lokushisa elilungile kubalulekile ekusebenzeni nokuqina.

Amadivaysi Ezokwelapha

Umkhakha wezokwelapha uzuza ngokusetshenziswa kwamabhodi esekethe e-ceramic emishinini ehlukahlukene yokuxilonga neyokwelapha. I-biocompatibility yabo kanye nokumelana namakhemikhali kubenza bafaneleke ukusetshenziswa ekufakweni kwezokwelapha kanye namadivayisi wokuqapha. Ukwengeza, ukwethembeka nokunemba kwabo kubalulekile kumishini efana nemishini ye-MRI namathuluzi okuxilonga aphathwayo, lapho ukusebenza okunembile nokungaguquki kubalulekile ekunakekelweni kwesiguli.

Ikusasa Le-Ceramic Circuit Boards

Ucwaningo emkhakheni wezinto zobumba kanye nezinqubo zokukhiqiza luvula indlela yokusetshenziswa okusha kwamabhodi esekethe e-ceramic. Ososayensi nonjiniyela bahlola izinhlanganisela ezintsha ze-ceramic, o-inki abaqhubayo, nezindlela zokwenza ukuze kuthuthukiswe ukusebenza nokunciphisa izindleko zama-PCB e-ceramic. Intuthuko ku-nanotechnology kanye nokukhiqiza okungeziwe kulindeleke ukuthi kuvule amathuba amasha okwakhiwa kwesekethe nokuhlanganiswa, kuqhubeke kwandise amakhono emishini kagesi.
