Kusiyana pakati pa ma PCB a Ceramic ndi ma PCB achikhalidwe a FR4
Tisanakambirane nkhaniyi, choyamba tiyeni timvetse tanthauzo la ma PCB a ceramic ndi chiyani komanso kuti ma PCB a FR4 ndi chiyani.
Ceramic Circuit Board imatanthauza mtundu wa bolodi la circuit lopangidwa kutengera zipangizo za ceramic, lomwe limadziwikanso kuti Ceramic PCB (bolodi la circuit losindikizidwa). Mosiyana ndi zinthu za pulasitiki zolimbikitsidwa ndi ulusi wagalasi (FR-4), ma ceramic circuit board amagwiritsa ntchito zinthu za ceramic, zomwe zingapereke kukhazikika kwa kutentha kwambiri, mphamvu yabwino yamakina, mphamvu zabwino za dielectric, komanso moyo wautali. Ma PCB a ceramic amagwiritsidwa ntchito kwambiri m'ma circuit otentha kwambiri, pafupipafupi kwambiri, komanso amphamvu kwambiri, monga magetsi a LED, ma amplifier amphamvu, ma semiconductor laser, ma RF transceivers, masensa, ndi zida zama microwave.
Circuit Board imatanthauza zinthu zoyambira zamagetsi, zomwe zimadziwikanso kuti PCB kapena printed circuit board. Ndi chonyamulira chosonkhanitsira zigawo zamagetsi posindikiza mapangidwe azitsulo pazitsulo zosagwiritsa ntchito mphamvu, kenako ndikupanga njira zoyendetsera kudzera munjira monga chemical corrosion, electrolytic copper, ndi kuboola.
Apa pali kufananiza pakati pa CCL ya ceramic ndi FR4 CCL, kuphatikizapo kusiyana kwawo, ubwino ndi kuipa kwawo.

PCB ya Ceramic
Magawo ogwiritsira ntchito zipangizo zosiyanasiyana:
Alumina Ceramic (Al2O3): Ili ndi kutchinjiriza kwabwino kwambiri, kukhazikika kwa kutentha kwambiri, kuuma, komanso mphamvu zamakanika kuti ikhale yoyenera zida zamagetsi zamagetsi zamphamvu kwambiri.
Aluminium Nitride Ceramics (AlN): Ndi kutentha kwambiri komanso kukhazikika bwino kwa kutentha, ndi yoyenera zida zamagetsi zamagetsi komanso magetsi a LED.
Zirconia ceramics (ZrO2): Ndi yamphamvu kwambiri, yolimba kwambiri komanso yolimba, yoyenera zida zamagetsi zamagetsi.
Magawo ogwiritsira ntchito njira zosiyanasiyana:
HTCC (High Temperature Co fired Ceramics): Yoyenera kugwiritsidwa ntchito pa kutentha kwambiri komanso mphamvu zambiri, monga zamagetsi zamagetsi, ndege, kulumikizana ndi satelayiti, kulumikizana ndi kuwala, zida zamankhwala, zamagetsi zamagalimoto, petrochemical ndi mafakitale ena. Zitsanzo za malonda ndi monga ma LED amphamvu kwambiri, ma amplifiers amphamvu, ma inductors, masensa, ma capacitor osungira mphamvu, ndi zina zotero.
LTCC (Zomera Zotentha Zotentha Zokhala ndi Co): Zoyenera kupanga zida zama microwave monga RF, microwave, antenna, sensa, fyuluta, chogawa mphamvu, ndi zina zotero. Kuphatikiza apo, ingagwiritsidwenso ntchito pazachipatala, zamagalimoto, zamlengalenga, zolumikizirana, zamagetsi ndi zina.

DBC (Direct Bond Copper): Yoyenera kutenthetsa kutentha kwa zipangizo zamagetsi amphamvu kwambiri (monga IGBT, MOSFET, GaN, SiC, ndi zina zotero) zomwe zimakhala ndi kutentha kwabwino komanso mphamvu ya makina. Zitsanzo za zinthuzi zikuphatikizapo ma module amagetsi, zamagetsi zamagetsi, zowongolera magalimoto amagetsi, ndi zina zotero.
DPC (Direct Plate Copper Multilayer Printed Circuit Board): imagwiritsidwa ntchito makamaka pochotsa kutentha kwa magetsi amphamvu a LED okhala ndi mawonekedwe a mphamvu yapamwamba, kutentha kwambiri, komanso magwiridwe antchito apamwamba amagetsi. Zitsanzo za malonda ndi monga magetsi a LED, ma LED a UV, ma LED a COB, ndi zina zotero.
LAM (Laser Activation Metallization for Hybrid Ceramic Metal Laminate): ingagwiritsidwe ntchito pochotsa kutentha ndi kukonza magwiridwe antchito amagetsi m'magetsi amphamvu kwambiri a LED, ma module amagetsi, magalimoto amagetsi, ndi zina. Zitsanzo za malonda ndi monga magetsi a LED, ma module amagetsi, oyendetsa magalimoto amagetsi, ndi zina zotero.
FR4 PCB
Mabodi onyamula a IC, mabodi a Rigid-Flex ndi ma HDI osawoneka/obisika kudzera pa mabodi ndi mitundu ya ma PCB omwe amagwiritsidwa ntchito kwambiri, omwe amagwiritsidwa ntchito m'mafakitale ndi zinthu zosiyanasiyana motere:
Bodi yonyamulira ya IC: Ndi bolodi yosindikizidwa yomwe imagwiritsidwa ntchito kwambiri, makamaka poyesa ma chip ndi kupanga zida zamagetsi. Ntchito zodziwika bwino zimaphatikizapo kupanga ma semiconductor, kupanga zamagetsi, ndege, zankhondo, ndi zina.
Bolodi Lolimba-Losinthasintha: Ndi bolodi lopangidwa ndi zinthu zosiyanasiyana lomwe limaphatikiza FPC ndi PCB yolimba, yokhala ndi ubwino wa mabwalo osinthasintha komanso olimba. Ntchito zambiri zimaphatikizapo zamagetsi, zida zachipatala, zamagetsi zamagalimoto, ndege, ndi zina.
HDI yobisika/yobisika kudzera pa bolodi: Ndi bolodi losindikizidwa lolumikizidwa kwambiri lomwe lili ndi mizere yambiri komanso malo otseguka pang'ono kuti likwaniritse kulongedza pang'ono komanso magwiridwe antchito apamwamba. Ntchito zodziwika bwino zimaphatikizapo kulumikizana kwa mafoni, makompyuta, zamagetsi, ndi zina.
