Ndi mabwalo amtundu wanji omwe angagwiritsidwe ntchito ndi ma PCB a ceramic?
Pali mitundu ingapo ya mabwalo omwe angagwiritsidwe ntchito ndi ma PCB a ceramic. Zotsatirazi ndi zina mwa zitsanzo.
Mabwalo othamanga kwambiri
Zozungulira za RF
Zozungulira zowotcha kutentha
Zozungulira zamagetsi
Zozungulira zolipirira kutentha
Kodi ma PCB a ceramic ndi okwera mtengo kuposa matabwa achikhalidwe a FR-4?
Inde, ma PCB a ceramic ndi okwera mtengo kuposa matabwa achikhalidwe a FR-4 popeza gawo lapansi la ceramic ndilatsopano komanso labwino kwambiri lazinthu za PCB.
Kodi ma PCB a ceramic amapangidwa bwanji?
Zotsatirazi ndi njira yosavuta yopangira ma PCB a ceramic.
Konzani zopangira → zosanjikiza zamkati zamkuwa → zokutira → kubowola → zotsalira zamkuwa zosanjikiza → kusindikiza chigoba cha solder → chithandizo chapamwamba → kusindikiza kwa silkscreen → kuyesa kotsegula/kwachidule → kuyezetsa komaliza → kuyika.
Kodi Richfulljoy amapanga multilayer ceramic PCB?
Inde, tili ndi luso lolemera kwambiri popanga ceramic multilayer PCB. Chonde lumikizanani ndi gulu lathu lamalonda kuti mupeze mtengo waulere pakupanga kwanu kwa ceramic PCB.
Kodi pali kusiyana kotani: Ceramic pcb vs FR4?
1. Magawo ndi osiyana;
2. Magwiritsidwe ndi osiyanasiyana;
3. Mitengo ndi yosiyana: gawo lapansi lopangidwa ndi mkuwa la ceramic ndilokwera mtengo kwambiri;
4, Zosiyana pakupanga: njira yopanga ceramic PCB ndiyovuta kwambiri.
Kodi pali zofunikira zina zapadera zomwe muyenera kukumbukira popanga PCB ya ceramic?
Popanga ma PCB a ceramic, sitiyenera kutengera kapangidwe kake mopepuka ndipo tiyenera kukumbukira zingapo.
Popanga PCB ya ceramic, tiyenera kusankha mosamala zida za dielectric zomwe tikufuna.
Kuwongolera koyendetsedwa kumafunika nthawi zonse mu ma PCB a ceramic, kotero opanga azitha kuwerengera mtengo wa impedance malinga ndi magawo azinthu (Er), makulidwe amkuwa, m'lifupi / malo amkuwa, makulidwe a dielectric, ndi zina zambiri.
Popeza zida za ceramic ndizokwera mtengo kwambiri kuposa zida za FR4, kapangidwe ka bolodi la ceramic kuyenera kuganizira mtengo wa PCB ndi mtengo wonse wa ntchito.
Ngati tizindikira zovuta zomwe zingachitike kumayambiriro kwa kamangidwe, titha kutsimikizira kuti zinthu zikuyenda bwino m'kupita kwanthawi. Ndikukonzekera mosamala, ma PCB a ceramic amatha kupereka mayankho abwino kwambiri pazogwiritsa ntchito zosiyanasiyana. Chonde lumikizanani nafe momasuka ngati muli ndi mafunso okhudza ma PCB a ceramic.
Kodi nthawi yotsogolera yopanga ceramic PCB ndi iti?
Nthawi yathu yotsogolera yopangira PCB ili pafupi masabata 1-3. Koma nthawi zina, tingafunike masabata angapo kuti tigule zinthu zapadera za ceramic. Chifukwa chake, zinthu ngati zamtundu wazinthu ndi ukadaulo wogwiritsidwa ntchito pa PCB zimatsimikizira nthawi yotsogolera yopangira ceramic PCB.
Kodi mtengo wa ceramic PCB ndi wotani?
Zinthu zotsatirazi zimatsimikizira mtengo wa ceramic PCB.
Zinthu zam'munsi (zofunika kwambiri);
Kuchuluka pa batch;
Njira Technology, monga akhungu/kukwiriridwa vias;
Zovuta kupanga, monga zolimba kwambiri impedance kulolerana, zolimba mkuwa m'lifupi kulolerana;
Zofunikira zina zapadera.
Kodi pali kusiyana kotani pakati pa Ceramic PCB ndi Teflon PCB?
Zida ndizosiyana:
Teflon ndi mtundu wa polyimide, womwe ndi mtundu wapadera wa pulasitiki wochita bwino kwambiri. Koma ceramic ndi mtundu wa pawiri wopangidwa ndi boron nitride, beryllium okusayidi ndi silicon carbide.
Zogwiritsira ntchito ndizosiyana:
Teflon PCBs nthawi zonse amagwiritsidwa ntchito kwa ma microwave ndi RF ntchito. Koma zida za ceramic nthawi zambiri zimalimbikitsidwa ndi kuphatikiza kwa zinthu zina, kotero magawo a ceramic amagwiritsidwa ntchito kwambiri.
Njira ndi njira zopangira PCB ndizosiyana:
Izi zili choncho chifukwa makhalidwe a mitundu iwiri ya zipangizo ndi osiyana kotheratu.
