Ii-capacitor ze-ceramic zizinto ze-elektroniki ezisebenzisa izixhobo ze-ceramic njengee-electrode ze-dielectric kunye neze-metallic ukugcina itshaja yombane. Zisetyenziswa kakhulu kwii-elektroniki zabathengi, unxibelelwano, ii-elektroniki zeemoto, kunye nezicelo zolawulo lwemizi-mveliso, apho zenza imisebenzi ebalulekileyo efana nokudibanisa, ukucoca, ukudibanisa, ukuqaqamba, kunye nokugcina amandla.
Ukuze kube lula ukugcina itshaja kunye nokwakha unxibelelwano lombane neesekethe zangaphandle, ii-electrode ziyinxalenye ebalulekileyo yesakhiwo se-capacitor. Ii-electrode zesinyithi zisasazwa kumacala omabini e-ceramic dielectric okanye zifakwe ngokwahlukeneyo kunye nee-dielectric layers kwizakhiwo ze-multilayer, kunye zenza uyilo lwe-capacitor olusisiseko. Xa kusetyenziswa i-voltage, ii-electrical charges ziyaqokelelana kwii-electrode ezimbini kwaye ziqhagamshelwe kwisekethe yangaphandle ngesakhiwo se-electrode.
1. Kutheni ixabiso lee-electrode zesilivere ezisetyenziswa rhoqo kwii-capacitors ze-ceramic liqhubeka linyuka?
Inkqubo yokwenziwa kwee-electrode eqhelekileyo kwii-capacitors ze-ceramic idla ngokusebenzisa inkqubo yokuprinta kunye nokudubula nge-silver paste. Le nkqubo ngokubanzi ibandakanya ukulungiswa kwe-ceramic substrate, ukuprinta i-silver paste, ukomisa, ukudubula ngobushushu obuphezulu, ukuhlolwa kwe-electrode, kunye nokucutshungulwa okulandelayo. Le teknoloji isetyenziswa kakhulu iminyaka emininzi, kunye neefomyula ze-silver-paste ezivuthiweyo, ubuchwepheshe bokuprinta kwesikrini, iinkqubo zokuprinta, kunye neenkqubo zokudubula. Izixhobo zayo zemveliso kunye neziseko ezixhasayo zizinzile, zinomqobo ophantsi ekuphunyezweni komgca wemveliso kunye nokuzivumelanisa kakuhle neemveliso ezineenkcazo ezahlukeneyo.
Kwangaxeshanye, i-silver paste isebenzisa umgubo wesilivere njengesixhobo sayo esiphambili sokuhambisa kwaye yenza i-electrode ngenkqubo yefilimu etyebileyo. Ngenxa yoko, umaleko wesilivere utyebile kakhulu, nto leyo ekhokelela ekusetyenzisweni kwesilivere okuphezulu ngeyunithi nganye yemveliso.
Xa amaxabiso esilivere ayephantsi kakhulu, impembelelo yeendleko ezinxulumene nokusetyenziswa kwesilivere ephezulu yayingabalulekanga kangako. Nangona kunjalo, njengoko amaxabiso esilivere eqhubeka enyuka kwixesha elide, olu lwakhiwo lweendleko luye lwabonakala ngakumbi. Ngokusekelwe kumaxabiso esilivere aqhelekileyo ngonyaka aguqulwe aba yi-RMB, ixabiso lesilivere lalimalunga ne-RMB 1.9/g ngo-2005, xa kuthelekiswa ne-RMB 9.2/g ngo-2025, nto leyo ebonisa ukunyuka okumalunga namaxesha angama-4.8 kwiminyaka engama-20.
Kubavelisi be-ceramic capacitor ephezulu, impembelelo yokunyuka kwamaxabiso esilivere iba nkulu ngakumbi njengoko ubungakanani bemveliso bukhula. Ukusetyenziswa kwesilivere okuphezulu ngeyunithi nganye, okuphindaphindwe ngamanani emveliso yonyaka ezigidi, amashumi ezigidi, okanye nangaphezulu, kunokuguqulela kwiindleko ezinkulu zezinto ezibonakalayo. Xa amaxabiso esilivere ehlala ekwinqanaba eliphezulu, inkqubo ye-electrode yesilivere-paste eqhelekileyo neyasekwa kakuhle ijongene noxinzelelo olukhulu oluvela kwiindleko zesinyithi esixabisekileyo.
Ngenxa yesi sizathu, ukunciphisa ukusetyenziswa kwesilivere kunye nokunciphisa ukuxhomekeka kwiintsimbi ezixabisekileyo kunye nokuguquguquka kwamaxabiso azo kuye kwaba yinto ebalulekileyo kubavelisi be-ceramic capacitor.
2. Indlela yokunciphisa iindleko ze-Zhenhua Vacuum: Ukusuka "ekutshintsheni isilivere ngobhedu" ukuya ekuveliseni ngokuqhubekayo ngobuninzi
Ukuphendula ekusetyenzisweni okuphezulu kwesinyithi esixabisekileyo, amanyathelo amaninzi enkqubo, kunye nokuvezwa kukuguquguquka kwexabiso lesilivere okunxulunyaniswa nee-electrode zesilivere ezisetyenziswa rhoqo, iZhenhua Vacuum ibihlola indlela yetekhnoloji ye-magnetron "ethatha indawo yesilivere" esekwe kwi-“copper replacement silver” kwii-electrode ze-ceramic capacitor kwaye ilandele ukunciphisa iindleko ngokusebenzisa ukwenziwa ngcono kwenkqubo kunye nokutshintshwa kwezinto.
Endaweni yokuxhomekeka kwimveliso ye-electrode yesilivere-paste eqhelekileyo, i-Zhenhua Vacuum isebenzisa iteknoloji ye-magnetron sputtering. Njengenkqubo ye-physical vapor deposition (PVD), i-magnetron sputtering ifaka izinto zesinyithi ngqo kumphezulu we-ceramic substrate kwindawo ye-vacuum ukuze yenze ifilimu ye-electrode.
Xa kuthelekiswa nokuprintwa kwesikrini sesilivere esiqhelekileyo, le nkqubo isusa amanyathelo aliqela aqhelekileyo, kuquka ukulungiswa kwesilivere-intlama, ukuprinta, ukomisa, kunye nokutshisa ngobushushu obuphezulu, ngaloo ndlela ifinyeza uthotho lwenkqubo iyonke kwaye inciphise ukuphathwa okuphakathi kunye nokusebenza ngesandla. Ekubeni intlama yesilivere kunye nezihlanganisi zayo zendalo kunye nabathwali bayo abanxulumene nayo akufuneki, le nkqubo inokunciphisa ukukhutshwa kwezinto eziphilayo kunye nenkunkuma yenkqubo enxulumene nokuveliswa kwe-electrode esekelwe kwintlama, inika amandla amakhulu emveliso ecocekileyo nezenzekelayo.
Ngokwembono yezinto ezisetyenziswayo, ubhedu lusetyenziswa njengesixhobo esiphambili sokuhambisa umbane endaweni yesilivere. Ubhedu lubonelela ngombane ogqwesileyo ngelixa ixabiso lalo liphantsi kakhulu kunelesilivere. Oku kwenza kube lula ukunciphisa ukusetyenziswa kwesinyithi esixabisekileyo kwinqanaba lezinto ezisetyenziswayo. Kwimveliso yomthamo ophezulu, olo tshintsho lwezinto lunokunciphisa iindleko zezinto ezisetyenziswa yi-electrode ngelixa lunciphisa impembelelo yokuguquguquka kwexabiso lesilivere kwiindleko zokuvelisa zizonke.
Nangona kunjalo, ukutshintsha isilivere ngekopolo ayikokutshintsha nje into ye-electrode ibe yenye. I-Copper ichaphazeleka lula yi-oxidation kumaqondo obushushu aphezulu, kwaye iinkqubo zokuprinta kunye nokudubula ze-copper-paste eziqhelekileyo zifuna ulawulo oluqinileyo lwe-paste, umoya wokudubula, kunye ne-process window. I-Magnetron sputtering, ngokuchaseneyo, yenza iifilimu zekopolo zibekwe ngqo kwindawo engenamoya. Ngokuyila iileya zokuncamathela, iileya eziqhubayo, kunye nezinye ii-stacks zefilimu ezisebenzayo, le nkqubo inokuphucula ukunamathela kwefilimu, uxinano, kunye nokusebenza kombane, ibonelela ngenye indlela yenkqubo yokuphunyezwa kweshishini "kwesilivere ethatha indawo yobhedu."
2.1 Ukusuka kuPhuhliso lweNkqubo ukuya kwiMveliso eNinzi: Umgca weMveliso ye-Zhenhua Vacuum's Double-Sided Continuous Magnetron Sputtering Line
Ukutshiza ngeMagnetron kunokubonelela ngendlela yobuchwephesha "yokuthatha indawo yesilivere ngobhedu," kodwa kwimveliso ye-ceramic capacitor ephezulu, ukuvelisa iisampulu ezigqunywe ngeplastiki kuphela akwanelanga. Umngeni ophambili kukufezekisa imveliso yobunzima bexesha elide, ezinzileyo, neqhubekayo.
Ukuze kuhlangatyezwane nale mfuneko, iZhenhua Vacuum iphuhlise umgca wemveliso yemagnetron eqhubekayo enamacala amabini yee-electrode ze-ceramic capacitor, edibanisa iteknoloji yokugquma i-vacuum kunye nemveliso ezenzekelayo. Emva kokungena kumgca wemveliso, iimveliso zidluliselwa rhoqo phakathi kwamagumbi enkqubo ahlukeneyo, ngelixa iifilimu ze-electrode zifakwa kumacala omabini kwinkqubo yemveliso efanayo. Oku kunciphisa isidingo sokujika ngesandla, ukulayisha nokukhupha ngokuphindaphindiweyo, kunye nokuphathwa okuphakathi phakathi kweenkqubo.
Izixhobo zamkela ulungelelwaniso oluqhubekayo lomgca wemveliso, olwenza ukuba iileya ezahlukeneyo zefilimu, kubandakanya iileya zokuncamathela okanye zotshintsho kunye neeleya eziqhubayo, zifakwe kwinkqubo efanayo edibeneyo. Ngokudluliswa kwezinto ngokuzenzekelayo, ulawulo oluchanekileyo lweparameter yenkqubo, kunye nolawulo lomthamo wemveliso, inkqubo iphucula ukufana kwefilimu kunye nokuzinza kwenkqubo ngexesha lemveliso ephezulu.
Le ndlela yenkqubo ikwangqinisiswe ixesha elide kwimveliso yobuninzi. Ngowama-2012, iZhenhua Vacuum yazisa umgca wemveliso yokutshiza imagnetron eqhubekayo enamacala amabini kwi-electrodes ze-ceramic capacitor kumthengi. Ukusukela ngo-2026, umgca wemveliso uhlale kwimveliso yobuninzi ezinzileyo kangangeminyaka eli-14, ubonelela ngokuqinisekiswa kwexesha elide kokuthembeka kwezixhobo, ukuhambelana kokugquma okunamacala amabini, kunye nokwenzeka kokuveliswa kobuninzi kwenkqubo "yobhedu ethatha indawo yesilivere" esekelwe kwimagnetron.
Utshintsho oluvela kwii-electrode zesilivere-paste eziqhelekileyo ukuya kwi-“copper replacement silver” ezisekelwe kwi-magnetron sputtering alukokutshintsha nje izinto. Lumela ulungelelwaniso oludibeneyo lwezixhobo, iinkqubo zokubeka, kunye neendlela zemveliso. Ngokusebenzisa itekhnoloji ye-magnetron sputtering kunye nomgca wemveliso oqhubekayo omacala amabini, i-Zhenhua Vacuum ithathe ingcamango “yecopper replacement silver” ngaphaya kwesisombululo sobugcisa kwaye yaya kwimveliso yobunzima ezinzileyo neqhubekayo.
Kwimveliso ye-ceramic capacitor ephezulu, ixabiso lezoqoqosho "lesilivere ethatha indawo yobhedu" linokufunyanwa ngokupheleleyo kuphela xa iindleko zezinto zincitshiswa, inkqubo yokuvelisa ilula, kwaye uzinzo lwemveliso yexesha elide lufezekiswa ngaxeshanye.
