Yiziphi izinhlobo zamasekethe ezingasetshenziswa nama-PCB e-ceramic?
Kunezinhlobo eziningana zamasekethe ezingasetshenziswa nama-PCB e-ceramic. Nazi ezinye izibonelo.
Amasekethe anesivinini esikhulu
Amasekethe e-RF
Amasekethe okushabalalisa ukushisa
Amasekethe okunikeza amandla
Amasekethe okunciphisa izinga lokushisa
Ingabe ama-PCB e-ceramic abiza kakhulu kunamabhodi e-FR-4 endabuko?
Yebo, ama-PCB e-ceramic abiza kakhulu kunamabhodi e-FR-4 endabuko njengoba i-substrate ye-ceramic iyinto entsha nesebenza kahle kakhulu ye-PCB.
Ama-PCB e-ceramic akhiqizwa kanjani?
Okulandelayo inqubo yokukhiqiza elula yama-PCB e-ceramic.
Lungisa izinto zokusetshenziswa → ukugoba umugqa wethusi ongaphakathi → ukulaminatha → ukubhoboza → umugqa wethusi ongaphandle ungqimba → ukuphrinta imaski yesolder → ukwelashwa kwendawo → ukuphrinta kwesikrini sesilika → ukuhlolwa okuvulekile/okufushane → ukuhlolwa kwekhwalithi kokugcina → ukupakishwa.
Ingabe iRichfulljoy ikhiqiza i-PCB yobumba enezingqimba eziningi?
Yebo, sinolwazi oluningi kakhulu ekukhiqizeni i-ceramic multilayer PCB. Sicela uxhumane nethimba lethu lokuthengisa ukuze uthole ikhotheshini yamahhala yokwenziwa kwe-ceramic PCB yakho.
Yimuphi umehluko omkhulu: i-PCB yobumba uma iqhathaniswa ne-FR4?
1. Izisekelo zihlukile;
2. Ukusetshenziswa kuhlukile;
3. Izindleko zihlukile: i-substrate ye-ceramic embozwe ngethusi ibiza kakhulu;
4, Ukukhiqiza okuhlukile: inqubo yokukhiqiza i-PCB yobumba inzima kakhulu.
Ingabe kukhona izinto ezikhethekile okufanele uzicabangele lapho uklama i-PCB yobumba?
Lapho siklama ama-PCB e-ceramic, akumelwe sithathe lo mklamo kalula futhi kufanele sikhumbule izinto eziningana ezibalulekile.
Lapho siklama i-PCB yobumba, kufanele sikhethe ngokucophelela izinto ze-dielectric zokusetshenziswa okufiswayo.
I-impedance elawulwayo iyadingeka njalo kuma-PCB e-ceramic, ngakho-ke abaklami kufanele babale inani le-impedance ngokuya ngamapharamitha ezinto (Er), ubukhulu bethusi, ububanzi bethusi/isikhala, ubukhulu be-dielectric, njll.
Njengoba izinto zobumba zibiza kakhulu kunezinto ze-FR4, ukwakheka kwebhodi lesekethe le-ceramic kufanele kucabangele izindleko ze-PCB kanye nentengo iyonke yokusetshenziswa.
Uma sibona izinkinga ezingaba khona ekuqaleni kwenqubo yokuklama, singaqinisekisa impumelelo ezigabeni zakamuva. Ngokuhlela ngokucophelela, ama-PCB obumba anganikeza izixazululo ezinhle kakhulu zezinhlelo zokusebenza ezahlukahlukene. Sicela uxhumane nathi ngokukhululekile uma unemibuzo mayelana nama-PCB obumba.
Isikhathi sokuhola sokukhiqiza i-PCB yobumba singakanani?
Isikhathi sethu esijwayelekile sokulethwa kwe-PCB singamaviki angu-1-3. Kodwa ngezinye izikhathi, singadinga amasonto ambalwa ukuthenga izinto ezikhethekile ze-ceramic. Ngakho-ke, izimo ezifana nohlobo lwezinto kanye nobuchwepheshe obusetshenziswa kwi-PCB zizonquma isikhathi esiqondile sokulethwa kwe-PCB ye-ceramic.
Iyini intengo ye-PCB yobumba?
Izici ezilandelayo zinquma izindleko ze-PCB zobumba.
Izinto ezingaphansi komhlaba (ingxenye ebaluleke kakhulu);
Inani ngebhetshi ngayinye;
Ubuchwepheshe Bezinqubo, njenge-vias ezingaboni/ezingcwatshwe;
Ubunzima ekukhiqizeni, njengokubekezelelana kwe-impedance okuqinile kakhulu, ukubekezelelana kobubanzi bethusi obuqinile;
Ezinye izidingo ezikhethekile.
Uyini umehluko phakathi kwe-Ceramic PCB ne-Teflon PCB?
Izinto zokwakha zihlukile:
I-Teflon uhlobo lwezinto ze-polyimide, okuwuhlobo olukhethekile lwepulasitiki esebenza kahle kakhulu. Kodwa i-ceramic uhlobo lwenhlanganisela eyenziwe nge-boron nitride, i-beryllium oxide kanye ne-silicon carbide.
Ukusetshenziswa kuhlukile:
Ama-Teflon PCB asetshenziswa njalo ekusetshenzisweni kwe-microwave kanye ne-RF. Kodwa izinto zobumba zivame ukuqiniswa ngenhlanganisela yezinye izinto, ngakho-ke izinto zobumba zisetshenziswa kabanzi.
Inqubo yokukhiqiza i-PCB kanye namasu ahlukile:
Lokhu kungenxa yokuthi izici zezinhlobo ezimbili zezinto zokwakha zihluke ngokuphelele.
