Ndi mitundu yanji ya ma circuit omwe angagwiritsidwe ntchito ndi ma PCB a ceramic?
Pali mitundu ingapo ya ma circuit omwe angagwiritsidwe ntchito ndi ma PCB a ceramic. Nazi zitsanzo zina.
Ma circuits othamanga kwambiri
Ma RF circuits
Madera otenthetsera kutentha
Mabwalo operekera magetsi
Mabwalo obwezera kutentha
Kodi ma PCB a ceramic ndi okwera mtengo kuposa ma board achikhalidwe a FR-4?
Inde, ma PCB a ceramic ndi okwera mtengo kuposa ma board achikhalidwe a FR-4 popeza gawo la ceramic ndi latsopano komanso lopambana kwambiri poyerekeza ndi zinthu za PCB.
Kodi ma PCB a ceramic amapangidwa bwanji?
Zotsatirazi ndi njira yosavuta yopangira ma PCB a ceramic.
Konzani zopangira → mkati mwa mkuwa wothira → laminating → kuboola → kunja kwa mkuwa wothira → kusindikiza chigoba cha solder → kukonza pamwamba → kusindikiza kwa silkscreen → kuyesa kotseguka/kwakafupi → kuyang'anira komaliza khalidwe → kulongedza.
Kodi Richfulljoy amapanga ma PCB a ceramic okhala ndi zigawo zambiri?
Inde, tili ndi luso lalikulu pakupanga ma PCB a ceramic multilayer. Chonde lumikizanani ndi gulu lathu logulitsa kuti mupeze mtengo waulere wa PCB yanu ya ceramic.
Kodi kusiyana kwakukulu ndi kotani: Ceramic pcb ndi FR4?
1. Ma substrate ndi osiyana;
2. Kagwiritsidwe ntchito kake ndi kosiyana;
3. Mitengo ndi yosiyana: choyikamo chadothi chokhala ndi mkuwa ndi chokwera mtengo kwambiri;
4, Zosiyanasiyana pakupanga: njira yopangira PCB ya ceramic ndi yovuta kwambiri.
Kodi pali zinthu zina zapadera zomwe muyenera kukumbukira popanga PCB ya ceramic?
Popanga ma PCB a ceramic, sitiyenera kutenga kapangidwe kake mopepuka ndipo tiyenera kukumbukira zinthu zingapo.
Popanga PCB ya ceramic, tiyenera kusankha mosamala zinthu zamagetsi zomwe zingagwiritsidwe ntchito.
Kuletsa kolamulidwa nthawi zonse kumafunika mu ma PCB a ceramic, kotero opanga ayenera kuwerengera mtengo wa kuletsa malinga ndi magawo azinthu (Er), makulidwe a mkuwa, m'lifupi/malo a mkuwa, makulidwe a dielectric, ndi zina zotero.
Popeza zinthu za ceramic ndizokwera mtengo kwambiri kuposa zinthu za FR4, kapangidwe ka bolodi la ceramic circuit board kayenera kuganizira mtengo wa PCB ndi mtengo wonse wogwiritsira ntchito.
Ngati titazindikira mavuto omwe angakhalepo kumayambiriro kwa njira yopangira, tikhoza kuonetsetsa kuti zinthu zikuyenda bwino mtsogolo. Pokonzekera bwino, ma PCB a ceramic angapereke mayankho abwino kwambiri pa ntchito zosiyanasiyana. Chonde titumizireni uthenga kwaulere ngati muli ndi mafunso okhudza ma PCB a ceramic.
Kodi nthawi yotsogolera yopanga PCB ya ceramic ndi iti?
Nthawi yathu yokhazikika yopangira PCB ndi pafupifupi milungu 1-3. Koma nthawi zina, tingafunike milungu ingapo kuti tigule zinthu zapadera zadothi. Chifukwa chake, zinthu monga mtundu wa zinthu ndi ukadaulo wogwiritsidwa ntchito pa PCB zidzatsimikizira nthawi yeniyeni yopangira PCB zadothi.
Kodi mtengo wa PCB ya ceramic ndi wotani?
Zinthu zotsatirazi zimatsimikiza mtengo wa PCB wa ceramic.
Zinthu zapansi panthaka (gawo lofunika kwambiri);
Kuchuluka pa gulu lililonse;
Ukadaulo wa Njira, monga ma vias osawoneka/obisika;
Zovuta pakupanga, monga kulekerera kwa impedance yolimba kwambiri, kulekerera kwa mkuwa wochepa m'lifupi;
Zofunikira zina zapadera.
Kodi pali kusiyana kotani pakati pa Ceramic PCB ndi Teflon PCB?
Zipangizozo ndi zosiyana:
Teflon ndi mtundu wa zinthu zopangidwa ndi polyimide, zomwe ndi mtundu wapadera wa pulasitiki wochita bwino kwambiri. Koma ceramic ndi mtundu wa mankhwala opangidwa ndi boron nitride, beryllium oxide ndi silicon carbide.
Kugwiritsa ntchito kumasiyana:
Ma PCB a Teflon nthawi zonse amagwiritsidwa ntchito popanga ma microwave ndi ma RF. Koma zinthu zadothi nthawi zambiri zimalimbikitsidwa ndi kuphatikiza kwa zinthu zina, kotero zinthu zadothi zimagwiritsidwa ntchito kwambiri.
Njira ndi njira zopangira PCB ndizosiyana:
Izi zili choncho chifukwa makhalidwe a mitundu iwiriyi ya zipangizo ndi osiyana kwambiri.
