Ubukhulu nobukhulu bamabhodi wesifunda se-ceramic

Kulokhu okuthunyelwe kwebhulogi, sizohlola amasayizi ajwayelekile nobukhulu bamabhodi wesifunda se-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 abajwayelekile nobukhulu 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 kusukela kumiklamo yezendlalelo eyodwa kuya kweziyisithupha. 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 buyahlukahluka 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:
Ukushisa okuphezulu kwe-thermal materials ye-ceramic kuqinisekisa 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 amabhodi esekethe e-ceramic.
