Izinhlobo ezahlukene zemiklamo yebhodi lesifunda se-ceramic

Kulokhu okuthunyelwe kwebhulogi, sizohlola izinhlobo ezahlukene zemiklamo yebhodi lesifunda se-ceramic kanye nezici zabo eziyingqayizivele.

Amabhodi esekethe e-Ceramic aya ngokuya aduma ngenxa yezinzuzo zawo eziningi ngaphezu kwezinto zebhodi lesifunda elivamile njenge-FR4 noma i-polyimide.Amabhodi wesifunda se-Ceramic aba yisinqumo sokuqala sezinhlelo zokusebenza ezihlukahlukene ngenxa ye-conductivity enhle kakhulu yokushisa, ukumelana nokushisa okuphezulu namandla amahle omshini.Njengoba isidingo sikhula, kanjalo nezinhlobonhlobo zemiklamo yebhodi lesifunda se-ceramic etholakala emakethe.

1. Ibhodi lesifunda le-ceramic elisekelwe ku-alumina:

I-Aluminium oxide, eyaziwa nangokuthi i-aluminium oxide, iyinto esetshenziswa kabanzi kumabhodi wesifunda se-ceramic.Inezici ezinhle kakhulu zokuvala ugesi futhi ilungele izinhlelo zokusebenza ezidinga amandla aphezulu e-dielectric.Amabhodi esekethe e-alumina ceramic angamelana namazinga okushisa aphezulu, awenze afanelekele ukusetshenziswa ezinhlelweni zamandla aphezulu njengama-electronics amandla kanye nezinhlelo zezimoto.Ukuqedwa kwayo okubushelelezi kanye ne-coefficient ephansi yokunwetshwa kwe-thermal kuyenza ifaneleke ezinhlelweni ezibandakanya ukuphathwa kokushisa.

2. Ibhodi lesekhethi ye-Aluminium nitride (AlN) yobumba:

Amabhodi esekethe e-Aluminium nitride Ceramic ane-conductivity ephakeme yokushisa uma kuqhathaniswa nama-alumina substrates.Avame ukusetshenziswa ezinhlelweni ezidinga ukuchithwa kokushisa okusebenzayo, okufana nezibani ze-LED, amamojula wamandla, kanye nemishini ye-RF/microwave.Amabhodi esekethe e-Aluminium nitride ahamba phambili ezinhlelweni zokusebenza zemvamisa ephezulu ngenxa yokulahleka kwawo okuphansi kwe-dielectric kanye nobuqotho besignali obuhle kakhulu.Ukwengeza, amabhodi esekethe e-AlN alula futhi anobungani bemvelo, okuwenza abe yisinqumo esifanele ezimbonini ezahlukahlukene.

3. Ibhodi lesifunda se-silicon nitride (Si3N4):

Amabhodi wesekethe we-Silicon nitride ceramic aziwa ngamandla awo okusebenza kahle kakhulu kanye nokumelana nokushaqeka okushisayo.Lawa maphaneli ngokuvamile asetshenziswa ezindaweni ezinokhahlo lapho kushintsha khona izinga lokushisa elidlulele, ukucindezela okukhulu, nezinto ezonakalisayo.Amabhodi wesifunda we-Si3N4 athola izinhlelo zokusebenza ezimbonini ezifana ne-aerospace, ukuzivikela, kanye nowoyela negesi, lapho ukwethembeka nokuqina kubalulekile.Ngaphezu kwalokho, i-silicon nitride inezindawo ezinhle zokuvikela ugesi, okwenza kube ukukhetha okuhle kakhulu kwezicelo zamandla aphezulu.

4. Ibhodi lesifunda le-LTCC (i-temperature ephansi yobumba eyenziwe ngobumba):

Amabhodi esekethe e-LTCC akhiqizwa kusetshenziswa amateyipu e-ceramic amaningi aphrintwa isikrini ngamaphethini okuqhuba.Izendlalelo ziyapakishwa bese zishiswa emazingeni okushisa aphansi, okwenza ibhodi lesifunda eliminyene kakhulu nelithembekile.Ubuchwepheshe be-LTCC buvumela izingxenye ze-passive ezifana nama-resistors, ama-capacitor nama-inductors ukuthi ahlanganiswe ngaphakathi kwebhodi lesifunda ngokwalo, okuvumela ukuguqulwa okuncane nokusebenza okuthuthukisiwe.Lawa mabhodi afanele ukuxhumana okungenantambo, ugesi wezimoto, kanye nemishini yezokwelapha.

5. Ibhodi lesifunda le-HTCC (i-ceramic co-fired co-fired ceramic board):

Amabhodi esekethe e-HTCC afana namabhodi e-LTCC ngokwenqubo yokukhiqiza.Kodwa-ke, amabhodi e-HTCC ashiswa emazingeni okushisa aphezulu, okuholela ekwandeni kwamandla emishini kanye namazinga okushisa aphezulu okusebenza.Lawa mabhodi ajwayele ukusetshenziswa ezinhlelweni zokushisa eziphezulu njengezinzwa zezimoto, ama-aerospace electronics, namathuluzi okumba ama-downhole.Amabhodi esekethe e-HTCC anokuqina okuhle kakhulu kwe-thermal futhi angakwazi ukumelana nokuhamba ngebhayisikili okwedlulele.

Ngokufigqiwe

Izinhlobo ezahlukene zamabhodi esekethe e-ceramic aklanyelwe ukuhlangabezana nezinhlobonhlobo zezidingo eziqondene nomkhakha.Kungakhathaliseki ukuthi izinhlelo zokusebenza zamandla aphezulu, ukuchithwa kokushisa okuphumelelayo, izimo zemvelo ezimbi kakhulu noma izidingo ze-miniaturization, imiklamo yebhodi lesifunda se-ceramic ingahlangabezana nalezi zidingo.Njengoba ubuchwepheshe buqhubeka nokuthuthuka, amabhodi esekethe e-ceramic kulindeleke ukuthi abambe iqhaza elibalulekile ekuvumelaneni nezinhlelo ze-elekthronikhi ezintsha nezithembekile kuzo zonke izimboni.
