Li-PCB tsa Ceramic sebelisa li-ceramics e le lisebelisoa tsa tsona tsa motheo, 'me li hloka mocheso o phahameng haholo oa tlhahiso ho feta li-PCB tse ling. Joaloka lisebelisoa tsa motheo tsa PCB, lirafshoa tse sebelisetsoang li-PCB li na le melemo ea bobeli ba FR4 le tšepe. Lisebelisoa tsa FR4 li kenya letsoho motlakase, empa conductivity ea mocheso e futsanehile; aluminium le koporo li na le conductivity e ntle ea mocheso, empa ke li-conductor. Li-PCB tsa Ceramic li na le conductivity e ntle ea mocheso 'me ha li hloke lera la ho kenya motlakase kaha li-ceramics ke li-insulators tse ntle.

Ha li-PCB tsa ceramic li kenngoa ka li-chips tsa LED, li-IC, le likarolo tse ling, li fetoha li-PCBA tsa ceramic. Li-LED li ka bokelloa holim'a li-PCB tsa ceramic ka ho kopanya mohala kapa mokhoa oa flip-chip. Li-PCBA tsa Ceramic hangata ke likarolo tsa mantlha lits'ebetsong tsa matla a phahameng le a maqhubu a phahameng, joalo ka lilaoli tsa motlakase oa koloi, lisebelisoa tse fapaneng tsa optical, li-converter tsa phapanyetsano, libeteri tsa matla a letsatsi, mabone a LED a hajoale...

Hobaneng ha ceramic PCB e tumme hakaale?

Katoloso e Phahameng ea Mocheso

Lebaka la pele leo ka lona liboto tsa ceramic li tummeng haholo lekaleng la lisebelisoa tsa elektroniki ke katoloso ea tsona e ntle ea mocheso. Ho hotle ho hlokomela hore phetisetso ea mocheso oa motheo oa ceramic e batla e tšoana le silicon mme e ka sebetsa joalo ka lisebelisoa tsa khokahano. Ntle le moo, o ka e sebelisa e le motho ea ikhethileng. Ka hona, ho na le tšebeliso e phahameng bakeng sa thepa ea mocheso ea mapolanka a ceramic, esita le maemong a mabe.

Botsitso

Tšebeliso ea ceramic e tlisa matla a tsitsitseng a dielectric, 'me u ka fetola tekanyo ea ho lahleheloa ke radiofrequency ho eketsa matla a sesebelisoa sa hau. Leha ho le joalo, ho sa tsotellehe boima ba bokaholimo, lisebelisoa tsa ceramic li tla le khanyetso ea tlhaho khahlanong le khoholeho ea lik'hemik'hale. Ho hanyetsa lik'hemik'hale tsa Ceramic ho ka fetoha ho hanyetsa metsi le mongobo.

Ho feto-fetoha ha maemo

U ka etsa linyeoe tse 'maloa tsa tšebeliso ho kopanya boto ea mantlha ea tšepe e nang le katoloso e phahameng ea mocheso. Ntle le moo, o ntse o ka fetola mokokotlo oa tšepe hore e be li-conductor tse tšepahalang u sebelisa mokhoa oa sintering. Ka hona, tšebeliso ea ceramic PCB e molemo ka lebaka la mocheso oa eona o phahameng oa ho sebetsa.

Ho tšoarella

Mokhoa o entsoeng ka boto ea ceramic o etsa hore ho be le nako e telele ka ho sebelisa thepa e ikhethang, e kang ho tiea. Seo se thibela PCB ea hau hore e se ke ea senyeha. Kahoo u ka kholiseha hore u ke ke ua fetola PCB ea hau haufinyane ka lebaka la matla a eona a ho tsofala butle. Hape, khanyetso e phahameng ea mocheso ea ceramic PCB e etsa hore e nahane ka mokhoa o fokotsehileng oa ho bola.

Ho ikamahanya le maemo

Qetellong, tšebeliso ea li-cores tsa tšepe e ka sebetsa e le li-carriers tse sa tsitsang tse fanang ka boima ba mechine. Thepa ena e etsa hore ho be bonolo ho sebelisa li-PCB tsa ceramic maemong afe kapa afe ka lebaka la ho hanyetsa ho hoholo ha kutu le ho taboha ho tloaelehileng.

Melemo ea ceramic PCB

Ho senya mocheso ke molemo o ka sehloohong oo ceramic e nang le oona ho feta lisebelisoa tse tloaelehileng tse kang FR-4 le tšepe e apereng PCB. Hobane likarolo li behiloe ka ho toba mapolanka, 'me ha ho na lera la ho itšehla thajana, ho phalla ha mocheso ka mapolanka ho sebetsa hantle haholo. Ntle le moo, thepa ea ceramic e ka ba le bothata ba mocheso o phahameng oa ts'ebetso (ho fihla ho 350 ° C), ho feta moo, e na le coefficient e tlase haholo ea katoloso ea mocheso (CTE), e lumellang hore ho be le likhetho tse ling tse lumellanang bakeng sa moralo oa PCB.

Ha ho bapisoa le li-PCB tsa setso tseo thepa ea tsona ea substrate e leng fiber ea khalase ea epoxy, polyimide, polystyrene le phenolic resin, li-PCB tsa ceramic li na le thepa e latelang:

E babatsehang mogote conductivity

Hanela khoholeho ea lik'hemik'hale

Matla a tsamaisanang le mochini

Etsa hore ho be bonolo ho kenya ts'ebetsong mokhoa oa ho latela maemo a phahameng

Tšebelisano ea karolo ea CTA

Ntlha ea ho qetela

Li-PCB tsa setso tse kopantsoeng le li-organic foundation substrates li hatela pele ho ea ho sekhahla se itseng se sa tloaelehang, ts'epahalo e phahameng, ho nepahala hantle, le ho tšoarella ha ho hlahisoa theknoloji ea chip indastering ea lisebelisoa tsa elektroniki. Liboto tsa potoloho ea Ceramic ke mofuta o mocha oa PCB o ntseng o hlahella indastering ea lisebelisoa tsa elektroniki ka lebaka la litšobotsi tsa bona tse ikhethang.

Li-PCB tsa Ceramic li fana ka melemo e mengata ho feta liboto tse tloaelehileng. Li-PCB tsa Ceramic li khona ho ikamahanya le maemo, ha li rarahane haholo, 'me li sebetsa hantle ho feta liboto tsa potoloho tse tloaelehileng ka lebaka la mocheso o phahameng oa mocheso le coefficient e tlase ea ho atolosa (CTE). Baenjiniere ba lumela hore li-PCB tsena ke khetho e ntle ka ho fetisisa bakeng sa lisebelisoa tsa motlakase tse hahang. Ka ts'epo, u na le mohopolo oa ho Tseba PCB ea Ceramic e Molemohali 'me joale u ka khetha e ntle ka ho fetisisa bakeng sa hau.
