Ma capacitor a Ceramic ndi zida zamagetsi zomwe zimagwiritsa ntchito zipangizo za ceramic ngati ma electrode a dielectric ndi achitsulo kuti zisunge mphamvu zamagetsi. Amagwiritsidwa ntchito kwambiri pamagetsi amagetsi, kulumikizana, zamagetsi zamagalimoto, ndi ntchito zowongolera mafakitale, komwe amagwira ntchito zofunika monga kusokoneza, kusefa, kulumikizana, kusinthasintha, ndi kusunga mphamvu.
Kuti magetsi azitha kusungidwa ndikukhazikitsa kulumikizana kwamagetsi ndi ma circuits akunja, ma electrode ndi gawo lofunikira kwambiri la kapangidwe ka capacitor. Ma electrode achitsulo amagawidwa mbali zonse ziwiri za dielectric ya ceramic kapena amaphatikizidwa mosiyanasiyana ndi zigawo za dielectric m'mapangidwe a multilayer, pamodzi ndikupanga kapangidwe ka capacitor koyambira. Pamene magetsi agwiritsidwa ntchito, ma charge amagetsi amasonkhana pa ma electrode awiriwa ndipo amalumikizidwa ku dera lakunja kudzera mu kapangidwe ka electrode.
1. N’chifukwa Chiyani Mtengo wa Ma Electrode A Silver-Paste A Ceramic Capacitors Ukupitirira Kukwera?
Njira yodziwika bwino yopangira ma electrode a ma capacitor a ceramic nthawi zambiri imagwiritsa ntchito njira yosindikizira ndi kuwombera siliva. Njirayi nthawi zambiri imakhala ndi kukonzekera ceramic substrate, kusindikiza siliva phala, kuumitsa, kuwombera kutentha kwambiri, kuyang'anira ma electrode, ndi kukonza pambuyo pake. Ukadaulo uwu wakhala ukugwiritsidwa ntchito kwambiri kwa zaka zambiri, ndi mapangidwe okhwima a siliva phala, ukadaulo wosindikiza pazenera, njira zosindikizira, ndi machitidwe owombera. Zipangizo zake zopangira ndi zomangamanga zothandizira ndizokhazikika bwino, ndi cholepheretsa chochepa pakukhazikitsa mzere wopanga komanso kusinthasintha bwino kuzinthu zomwe zili ndi mawonekedwe osiyanasiyana.
Nthawi yomweyo, phala lasiliva limagwiritsa ntchito ufa wasiliva ngati gawo lalikulu loyendetsera ndipo limapanga elekitirodi kudzera mu njira yokhuthala kwambiri. Zotsatira zake, wosanjikiza wasiliva umakhala wokhuthala kwambiri, zomwe zimapangitsa kuti siliva igwiritsidwe ntchito kwambiri pa chinthu chilichonse.
Pamene mitengo ya siliva inali yotsika, zotsatira za mtengo zomwe zimagwirizanitsidwa ndi kugwiritsidwa ntchito kwa siliva wambiri sizinali zazikulu kwenikweni. Komabe, pamene mitengo ya siliva ikupitirira kukwera kwa nthawi yayitali, kapangidwe ka mtengo kameneka kakuonekera kwambiri. Kutengera mitengo yapakati ya siliva pachaka yomwe inasinthidwa kukhala RMB, mtengo wa siliva unali pafupifupi RMB 1.9/g mu 2005, poyerekeza ndi pafupifupi RMB 9.2/g mu 2025, zomwe zikuyimira kuwonjezeka kwa pafupifupi nthawi 4.8 pazaka 20.
Kwa opanga ma capacitor a ceramic omwe ali ndi mphamvu zambiri, kukwera kwa mitengo ya siliva kumakhala kofunikira kwambiri pamene kuchuluka kwa zinthu zomwe amapanga kukukulirakulira. Kugwiritsa ntchito siliva kochuluka pa unit iliyonse, kochulukitsidwa ndi kuchuluka kwa zinthu zomwe amapanga pachaka kwa mamiliyoni, makumi mamiliyoni, kapena kuposerapo, kumatha kubweretsa ndalama zambiri pazinthu zonse. Mitengo ya siliva ikadali pamlingo wokwera, njira yachikhalidwe komanso yokhazikika ya siliva-paste electrode imakumana ndi kupsinjika kwakukulu kuchokera ku mtengo wamtengo wapatali wachitsulo.
Poganizira izi, kuchepetsa kugwiritsa ntchito siliva ndi kuchepetsa kudalira zitsulo zamtengo wapatali komanso kusinthasintha kwa mitengo kwakhala zinthu zofunika kwambiri kwa opanga ma capacitor a ceramic.
2. Njira Yochepetsera Mtengo ya Zhenhua Vacuum: Kuchokera ku "Kusintha Siliva Mkuwa" Kupita ku Kupanga Zinthu Mosalekeza
Poyankha kugwiritsidwa ntchito kwambiri kwa chitsulo chamtengo wapatali, njira zingapo zogwirira ntchito, komanso kusinthasintha kwa mitengo yasiliva komwe kumakhudzana ndi ma electrode achikhalidwe a siliva, Zhenhua Vacuum yakhala ikufufuza njira yaukadaulo ya "mkuwa wolowa m'malo mwa siliva" yochokera ku magnetron yopangira ma electrode a ceramic capacitor ndipo yayesetsa kuchepetsa ndalama kudzera mu kukonza njira komanso kusintha zinthu.
M'malo modalira njira yopangira ma electrode a siliva, Zhenhua Vacuum imagwiritsa ntchito ukadaulo wothira ma electrode. Monga njira yothira nthunzi yeniyeni (PVD), kuthira ma electron kumaika zinthu zachitsulo mwachindunji pamwamba pa ceramic substrate pamalo otayira ma electrode kuti apange filimu ya electrode.
Poyerekeza ndi kusindikiza kwa silver-paste kwachizolowezi, njirayi imachotsa njira zingapo zachikhalidwe, kuphatikizapo kukonzekera silver-paste, kusindikiza, kuumitsa, ndi kuwombera kutentha kwambiri, motero kufupikitsa unyolo wonse wa njira ndikuchepetsa kugwira ntchito kwapakati komanso kugwira ntchito ndi manja. Popeza silver paste ndi zomangira zake zachilengedwe sizikufunika, njirayi ingachepetsenso kutulutsa kwachilengedwe ndi zinyalala za njira zokhudzana ndi kupanga ma electrode opangidwa ndi phala, zomwe zimapangitsa kuti pakhale kupanga koyera komanso kodziyimira pawokha.
Kuchokera pamalingaliro a zinthu, mkuwa umagwiritsidwa ntchito ngati chinthu chachikulu choyendetsera magetsi m'malo mwa siliva. Mkuwa umapereka mphamvu zamagetsi zabwino kwambiri pomwe mtengo wake ndi wotsika kwambiri kuposa wa siliva. Izi zimathandiza kuchepetsa kwambiri kugwiritsidwa ntchito kwa chitsulo chamtengo wapatali pamlingo wa zinthuzo. Pakupanga zinthu zambiri, kusintha zinthu koteroko kumatha kuchepetsa mtengo wa zinthu zama electrode pomwe kumachepetsa kusinthasintha kwa mitengo ya siliva pamitengo yonse yopangira.
Komabe, kusintha siliva ndi mkuwa si nkhani yongosintha zinthu za electrode imodzi kukhala ina. Mkuwa umakhala wovuta kusungunuka kutentha kwambiri, ndipo njira zosindikizira ndi kuwotcha zachikhalidwe za mkuwa zimafuna kuwongolera mwamphamvu kapangidwe ka phala, mlengalenga woyaka, ndi zenera la njira. Mosiyana ndi zimenezi, magnetron sputtering imathandiza kuti mafilimu a mkuwa azisungidwa mwachindunji pamalo opanda mpweya. Kudzera mu kapangidwe ka zigawo zomatira, zigawo zoyendetsera mpweya, ndi ma stack ena ogwira ntchito, njirayi imatha kusintha kumatira kwa filimu, kuchulukana, ndi magwiridwe antchito amagetsi, kupereka njira ina yogwiritsira ntchito mafakitale poyika "siliva wolowa m'malo mwa mkuwa."
2.1 Kuchokera pa Kupanga Njira Kupita ku Kupanga Zinthu Zambiri: Mzere Wopanga Magnetron Wosalekeza wa Zhenhua Vacuum Wokhala ndi Mbali Ziwiri
Kutulutsa kwa Magnetron kungapereke njira yaukadaulo ya "mkuwa wolowa m'malo mwa siliva," koma popanga ma capacitor a ceramic ambiri, kupanga zitsanzo zokutidwa zokha sikokwanira. Vuto lalikulu ndikupeza kupanga zinthu zambiri kwa nthawi yayitali, kokhazikika, komanso kosalekeza.
Pofuna kukwaniritsa izi, Zhenhua Vacuum yapanga mzere wopangira maginito wopitilira mbali ziwiri wa ma electrode a ceramic capacitor, kuphatikiza ukadaulo wophimba vacuum ndi kupanga kokha. Pambuyo polowa mzere wopanga, zinthuzo zimasamutsidwa nthawi zonse pakati pa zipinda zosiyanasiyana zamakina, pomwe mafilimu a maginito amaikidwa mbali zonse ziwiri mu dongosolo lomwelo lopangira. Izi zimachepetsa kufunikira kotembenuza ndi manja, kukweza ndi kutsitsa mobwerezabwereza, komanso kugwira ntchito pakati pa njira.
Zipangizozi zimagwiritsa ntchito njira yopangira mosalekeza, zomwe zimathandiza kuti magawo osiyanasiyana a filimu, kuphatikizapo zigawo zomatira kapena zosinthira ndi zigawo zoyendetsera, ziikidwe mkati mwa dongosolo lomwelo lolumikizidwa. Kudzera mu kusamutsa zinthu zokha, kuwongolera molondola magawo a njira, komanso kasamalidwe ka ntchito yopangira, dongosololi limawongolera kufanana kwa makulidwe a filimu ndi kukhazikika kwa njira panthawi yopanga zinthu zambiri.
Njira imeneyi yakhala ikutsimikiziridwanso kwa nthawi yayitali pakupanga zinthu zambiri. Mu 2012, Zhenhua Vacuum idapereka mzere wopangira zinthu zambiri wa magnetron continuous side-side wa ma electrode a ceramic capacitor kwa kasitomala. Pofika mu 2026, mzere wopangira zinthu wakhalabe wokhazikika pakupanga zinthu zambiri kwa zaka 14, zomwe zimatsimikizira kudalirika kwa zida, kukhazikika kwa zinthu ziwiri, komanso kuthekera kopanga zinthu zambiri pogwiritsa ntchito njira ya "copper replacement silver" ya magnetron.
Kusintha kuchoka pa ma electrode achikhalidwe a siliva-phala kupita ku "siliva wolowa m'malo mwa mkuwa" wopangidwa ndi magnetron sikungosintha zinthu zokha. Kumayimira kukonza bwino zinthu, njira zosungiramo zinthu, ndi njira zopangira. Kudzera muukadaulo wa magnetron sputtering ndi mzere wopanga zinthu wopitilira mbali ziwiri, Zhenhua Vacuum yatengera lingaliro la "siliva wolowa m'malo mwa mkuwa" kupitirira njira yaukadaulo ndikupangitsa kuti ikhale yokhazikika komanso yochulukirapo.
Pakupanga ma capacitor a ceramic ambiri, phindu la "siliva wolowa m'malo mwa mkuwa" lingathe kudziwika bwino pokhapokha ngati ndalama zogulira zinthu zachepetsedwa, njira yopangira zinthuyo yakonzedwa bwino, ndipo kukhazikika kwa nthawi yayitali pakupanga zinthu kumachitika nthawi imodzi.
-Nkhaniyi yasindikizidwa ndiwopanga zida zophikira vacuum Zhenhua Vacuum
