Ceramic capacitors zvinhu zvemagetsi zvinoshandisa zvinhu zveceramic sema electrodes e dielectric ne metallic kuchengetedza magetsi. Anoshandiswa zvakanyanya mumagetsi evatengi, kutaurirana, magetsi emotokari, uye mashandisirwo ekudzora maindasitiri, uko anoita mabasa akakosha akadai sekupatsanura, kusefa, kubatanidza, kurira, uye kuchengetedza simba.
Kuti zvigoneke kuchengetedza chaji uye kusimbisa kubatana kwemagetsi nematunhu ekunze, maelectrode chikamu chakakosha chechimiro che capacitor. Maelectrode esimbi anoparadzirwa kumativi ese e ceramic dielectric kana kuti anoiswa pamwe chete ne dielectric layers mu multilayer structures, pamwe chete zvichiumba basic capacitor architecture. Kana voltage ikashandiswa, magetsi anoungana pa electrodes maviri uye anobatanidzwa kune external circuit kuburikidza ne electrode structure.
1. Sei Mutengo weMaelectrode eSilver-Paste eCeramic Capacitors Uchiri Kukwira?
Maitiro ekugadzira ma electrode echinyakare ema capacitors e ceramic anowanzo shandisa nzira yekudhinda nekupisa ma electrode esirivha. Maitiro aya anowanzo kuve nekugadzira ceramic substrate, kudhinda ma sirivha, kuomesa, kupisa nekupisa kwakanyanya, kuongorora ma electrode, uye kugadzirisa kunotevera. Iyi tekinoroji yave ichishandiswa zvakanyanya kwemakore mazhinji, ine ma formulations esirivha-paste akakura, matekinoroji ekudhinda skrini, maitiro ekudhinda, uye masisitimu ekupisa. Midziyo yayo yekugadzira nezvivakwa zvinotsigira zvakasimbiswa zvakanaka, ine chipingamupinyi chidiki pakuitwa kwemutsara wekugadzira uye kugona kuchinjika zvakanaka kuzvigadzirwa zvine hunyanzvi hwakasiyana.
Panguva imwe chete, silver paste inoshandisa silver powder sechinhu chikuru chinofambisa magetsi uye inoumba electrode kuburikidza nemaitiro akakora-firimu. Nekuda kweizvozvo, sirivha yacho yakakora zvichienzaniswa, zvichiita kuti sirivha ishandiswe zvakanyanya pachikamu chimwe nechimwe.
Mitengo yesirivha payakanga yakaderera, kukanganiswa kwemitengo kwakabatana nekushandiswa kwesirivha kwakakwira kwakanga kusina kukosha. Zvisinei, sezvo mitengo yesirivha yakaramba ichikwira kwenguva refu, chimiro ichi chemitengo chave pachena zvakanyanya. Zvichienderana neavhareji yemitengo yesirivha yakashandurwa kuita RMB pagore, mutengo wesirivha waive RMB 1.9/g muna 2005, zvichienzaniswa neRMB 9.2/g muna 2025, zvichireva kuwedzera kweinenge ka4.8 mumakore makumi maviri.
Kune vagadziri vema ceramic capacitor ane huwandu hwakawanda, kukwira kwemitengo yesirivha kunowedzera kukosha sezvo huwandu hwekugadzira huchikura. Kushandiswa kwesirivha kwakakwira payuniti imwe neimwe, kwakawedzerwa nehuwandu hwekugadzirwa kwegore negore hwemamiriyoni, makumi emamiriyoni, kana kutopfuura zvikamu, kunogona kushandura kuita mitengo yakakura yezvinhu. Kana mitengo yesirivha ikaramba iri padanho rakakwirira, maitiro emagetsi esirivha-paste anotarisana nekumanikidzwa kwakanyanya kubva kumitengo yesimbi inokosha.
Zvichienderana neizvi, kuderedza kushandiswa kwesirivha uye kuderedza kuvimba nesimbi dzinokosha uye kuchinja-chinja kwemitengo kwave zvinhu zvakakosha kune vagadziri vema ceramic capacitor.
2. Nzira yeZhenhua yekuderedza Mutengo: Kubva pa "Kutsiva Sirivha nemhangura" kusvika pakugadzirwa kwehuwandu hunoramba huripo
Mukupindura kushandiswa kwakanyanya kwesimbi inokosha, matanho akawanda ekugadzira, uye kuratidzwa kwekuchinja kwemitengo yesirivha kunoenderana nemaelectrode esirivha akajairika, Zhenhua Vacuum yanga ichitsvaga nzira ye magnetron sputtering-based "copper replacement silver" tekinoroji yema electrodes e ceramic capacitor uye yakaramba ichidzikisa mitengo kuburikidza nekugadzirisa maitiro uye kutsiva zvinhu.
Pane kuvimba nekugadzirwa kwema electrode esirivha-paste, Zhenhua Vacuum inoshandisa tekinoroji ye magnetron sputtering. Senzira yekuisa vapor deposition (PVD), magnetron sputtering inoisa simbi zvakananga pamusoro pe ceramic substrate munzvimbo isina chinhu kuti igadzire electrode film.
Zvichienzaniswa nekudhinda kwesirivha-paste kwechiratidziro chemazuva ano, maitiro aya anobvisa matanho akati wandei echinyakare, anosanganisira kugadzirira silver-paste, kudhinda, kuomesa, uye kupisa zvakanyanya, nokudaro zvichipfupisa cheni yese yemaitiro uye kuderedza kubata kwepakati uye mashandiro emaoko. Sezvo silver paste nezvimwe zvinosunga organic pamwe nezvinotakura zvisingadiwi, maitiro aya anogonawo kuderedza kusvibiswa kweorganic uye marara eprocess ane chekuita nekugadzirwa kwe electrode yakagadzirwa ne paste, zvichipa mukana wakakura wekugadzira kwakachena uye otomatiki.
Kubva pamaonero ezvinhu, mhangura inoshandiswa sechinhu chikuru chinofambisa magetsi kutsiva sirivha. Mhangura inopa simba remagetsi rakanaka nepo mutengo wayo wakaderera zvakanyanya pane wesirivha. Izvi zvinoita kuti kushandiswa kwesimbi inokosha kuderedzwa zvakanyanya. Pakugadzirwa kwezvinhu zvakawanda, kuchinjana kwezvinhu kwakadaro kunogona kuderedza mitengo yezvinhu zvemagetsi ukuwo kuchideredza kukanganisa kwemitengo yesirivha pamitengo yekugadzira.
Zvisinei, kutsiva sirivha nemhangura hakusi kungochinja chimwe chinhu cheelectrode kuita chimwe. Mhangura inogona kuoxidation pakupisa kwakanyanya, uye maitiro ekudhinda nekupisa mhangura-paste anongoda kudzora kwakasimba kwekugadzirwa kwepaste, mhepo inopisa, uye hwindo rekugadzirisa. Magnetron sputtering, zvakasiyana, inobvumira mafirimu emhangura kuiswa zvakananga munzvimbo isina chinhu. Kuburikidza nekugadzirwa kwezvikamu zvekunamatira, zvikamu zvinofambisa, uye mamwe mastacks emafirimu anoshanda, maitiro aya anogona kuvandudza kubatana kwemafirimu, huwandu, uye mashandiro emagetsi, zvichipa imwe nzira yekushanda kwemaindasitiri ekushandisa "sirivha inotsiva mhangura."
2.1 Kubva paKugadzira Maitiro Kusvika paKugadzirwa Kwakawanda: Mutsetse weKugadzira Magnetron Sputtering weZhenhua Vacuum une Side-Side mbiri
Kusveta simbi dzeMagnetron kunogona kupa nzira yehunyanzvi ye "kutsiva sirivha nemhangura," asi pakugadzira capacitor yeceramic yakawanda, kugadzira sampuli dzakaputirwa chete hakuna kukwana. Dambudziko guru nderekuwana kugadzirwa kwenguva refu, kwakagadzikana, uye kunoramba kuripo.
Kuti igadzirise zvinodiwa izvi, Zhenhua Vacuum yakagadzira mutsetse wekugadzira magnetron unopfungaira une mativi maviri wema electrode e ceramic capacitor, uchibatanidza tekinoroji ye vacuum coating nekugadzirwa otomatiki. Mushure mekupinda mumutsetse wekugadzira, zvigadzirwa zvinogara zvichitamiswa pakati pemakamuri akasiyana ekugadzira, nepo mafirimu e electrode achiiswa kumativi ese ari maviri musystem imwe chete yekugadzira. Izvi zvinoderedza kudiwa kwekuchinjika nemaoko, kurodha nekuburitsa zvinhu kakawanda, uye kubata pakati pema process.
Midziyo iyi inoshandisa nzira yekugadzirwa inoenderera mberi, zvichiita kuti zvikamu zvakasiyana zvemafirimu, kusanganisira zvikamu zvinonamatira kana kuti zvinochinja uye zvikamu zvinofambisa, zviiswe mukati mehurongwa humwe chete hwakabatanidzwa. Kuburikidza nekutamiswa kwezvinhu otomatiki, kutonga kwakaringana kwema process-parameter, uye manejimendi yekugadzirwa, sisitimu iyi inovandudza kufanana kweukobvu hwemafirimu uye kugadzikana kwemaitiro panguva yekugadzira yakawanda.
Nzira iyi yekushanda yakaongororwawo kwenguva refu mukugadzirwa kwesimbi. Muna 2012, Zhenhua Vacuum yakapa mutengi mutsetse wekugadzira simbi unoenderera mberi wemagnetron sputtering we ceramic capacitor electrodes. Kubva muna 2026, mutsetse wekugadzira wakaramba wakagadzikana kwemakore gumi nemana, zvichipa kusimbiswa kwenguva refu kwekuvimbika kwemidziyo, kuenderana kwesimbi inovhara simbi, uye kugona kwekugadzira simbi inoburitsa ...
Kuchinja kubva pamaelectrode esirivha-paste echinyakare kuenda ku "sirivha inotsiva mhangura" yakavakirwa pamagnetron hakusi kungotsiva zvinhu chete. Kunomiririra kugadziriswa kwakarongeka kwezvinhu, maitiro ekuisa zvinhu, uye nzira dzekugadzira. Kuburikidza netekinoroji ye magnetron sputtering uye mutsetse wekugadzira unoenderera mberi une mativi maviri, Zhenhua Vacuum yakatora pfungwa ye "sirivha inotsiva mhangura" kupfuura mhinduro yehunyanzvi uye kuita kugadzirwa kwakasimba, kunoramba kuripo.
Pakugadzira ceramic capacitor ine huwandu hwakawanda, kukosha kwehupfumi kwe "sirivha inotsiva mhangura" kunogona kuonekwa zvizere kana mitengo yezvinhu yaderedzwa, maitiro ekugadzira akarongeka, uye kugadzikana kwekugadzira kwenguva refu kunowanikwa panguva imwe chete.
