Ubukhulu nobukhulu bamabhodi wesifunda se-ceramic

Kulokhu okuthunyelwe kwebhulogi, sizohlola amasayizi ajwayelekile nobukhulu bamabhodi esekethe e-ceramic.

Amabhodi esekethe e-Ceramic aya ngokuya ethandwa kakhulu embonini ye-elekthronikhi ngenxa yezici zawo eziphakeme nokusebenza kwawo uma kuqhathaniswa nama-PCB endabuko (Amabhodi Esifunda Aphrintiwe).Ayaziwa nangokuthi ama-PCB e-ceramic noma ama-substrates e-ceramic, lawa mabhodi ahlinzeka ngokuphatha okushisayo okuhle kakhulu, amandla aphezulu okusebenza kanye nokusebenza okuhle kakhulu kukagesi.

1. Uhlolojikelele lwamabhodi esekethe e-ceramic:

Amabhodi esekethe e-Ceramic enziwe ngezinto zobumba ezifana ne-aluminium oxide (Al2O3) noma i-silicon nitride (Si3N4) esikhundleni sezinto ezijwayelekile ze-FR4 ezisetshenziswa kuma-PCB omdabu.Izinto ze-Ceramic zine-conductivity engcono yokushisa futhi zingakhipha ngokuphumelelayo ukushisa ezingxenyeni ezifakwe ebhodini.Ama-PCB eCeramic asetshenziswa kakhulu ezinhlelweni ezidinga amandla aphezulu namasiginali wemvamisa ephezulu, njengama-electronics amandla, ukukhanya kwe-LED, i-aerospace kanye nezokuxhumana.

2. Ubukhulu nobukhulu bamabhodi esekethe yobumba:

Osayizi nobukhulu bebhodi lesifunda seCeramic bungahluka kuye ngezinhlelo zokusebenza ezithile kanye nezidingo zokuklama.Kodwa-ke, kukhona osayizi nobukhulu obujwayelekile obusetshenziswa kakhulu embonini.Ake singene kulezi zici:

2.1 Ubude, ububanzi nokuqina:
Amabhodi esekethe e-Ceramic afika ngobude obuhlukahlukene, ububanzi nobukhulu ukuze avumelane nemiklamo ehlukene kanye nokusetshenziswa.Ubude obujwayelekile busuka kumamilimitha ambalwa kuya kumakhulu amaningana amamilimitha, kanti ububanzi bungahluka ukusuka kumamilimitha ambalwa kuya cishe kumamilimitha angama-250.Ngokuqondene nobukhulu, ngokuvamile buyi-0.25 mm kuya ku-1.5 mm.Kodwa-ke, lawa masayizi angenziwa ngokwezifiso ukuze ahlangabezane nezidingo ezithile zephrojekthi.

2.2 Inani lezendlalelo:
Inani lezendlalelo ebhodini lesifunda se-ceramic linquma ubunkimbinkimbi nokusebenza kwalo.Ama-PCB e-Ceramic angaba nezendlalelo eziningi, ngokuvamile ezisukela kumiklamo yezendlalelo eziyisithupha.Izendlalelo ezengeziwe zivumela ukuhlanganiswa kwezingxenye ezengeziwe kanye nokulandela, okusiza imiklamo yesekethe ephezulu.

2.3 Usayizi wembobo:
Ama-Ceramic PCB asekela amasayizi wokuvula ahlukene kuye ngezidingo zohlelo lokusebenza.Izimbobo zingahlukaniswa zibe izinhlobo ezimbili: ezipulekwe ngezimbobo (PTH) nezingagqitshwa ngezimbobo (NPTH).Osayizi bezimbobo ezijwayelekile be-PTH basukela ku-0.25 mm (10 mils) kuya ku-1.0 mm (40 mils), kuyilapho osayizi bezimbobo ze-NPTH bangaba mancane njengo-0.15 mm (6 mils).

2.4 Ukulandelela kanye nobubanzi besikhala:
Ukulandelela kanye nobubanzi besikhala kumabhodi wesekethe ye-ceramic kudlala indima ebalulekile ekuqinisekiseni ubuqotho besignali efanele nokusebenza kukagesi.Ububanzi bokulandelela obujwayelekile busuka ku-0.10 mm (4 mils) ukuya ku-0.25 mm (10 mils) futhi buyahlukahluka ngokusekelwe emandleni okuphatha amanje.Ngokunjalo, ububanzi begebe buyahluka phakathi kuka-0.10 mm (4 mils) no-0.25 mm (10 mls).

3. Izinzuzo zamabhodi esekethe e-ceramic:

Kubalulekile ukuqonda amasayizi ajwayelekile nobukhulu bamabhodi esekethe e-ceramic, kodwa kubalulekile ngokulinganayo ukuqonda izinzuzo ezinikezayo:

3.1 Ukuphathwa kokushisa:
I-conductivity ephezulu yokushisa yezinto ze-ceramic iqinisekisa ukuchithwa kokushisa okusebenzayo kwezingxenye zamandla, ngaleyo ndlela kwandise ukuthembeka kwesistimu jikelele.

3.2 Amandla omshini:
Amabhodi wesifunda se-Ceramic anamandla amahle kakhulu emishini, awenza amelana kakhulu nezinto ezahlukahlukene zangaphandle njengokudlidliza, ukushaqeka nezimo zemvelo.

3.3 Ukusebenza kukagesi:
Ama-PCB e-Ceramic anokulahlekelwa okuphansi kwe-dielectric kanye nokulahlekelwa kwesignali ephansi, okuvumela ukusebenza kwe-high-frequency kanye nokuthuthukisa ubuqotho besignali.

3.4 I-Miaturization kanye ne-high-density design:
Ngenxa yobukhulu bawo obuncane kanye nezakhiwo ezingcono zokushisa, amabhodi esekethe e-ceramic anika amandla i-miniaturization kanye nemiklamo ephezulu kakhulu ngenkathi egcina ukusebenza okuhle kakhulu kukagesi.

4. ekuphetheni:

Osayizi abajwayelekile nobukhulu bamabhodi esekethe e-ceramic kuyahlukahluka kuye ngezidingo zohlelo lokusebenza nedizayini.Ubude nobubanzi bawo busukela kumamilimitha ambalwa kuya kumakhulu amaningana amamilimitha, kanti ukujiya kwawo kuhluka kusuka ku-0.25 mm kuya ku-1.5 mm.Inani lezendlalelo, usayizi wembobo, nobubanzi bokulandelela nakho kudlala indima ebalulekile ekunqumeni ukusebenza nokusebenza kwama-PCB e-ceramic.Ukuqonda lobu bukhulu kubalulekile ekuklameni nasekusebenziseni amasistimu e-elekthronikhi asebenzayo asebenzisa ngokunenzuzo amabhodi esekethe e-ceramic.
