Capacitors za Ceramic ni ibice by'ikoranabuhanga bikoresha ibikoresho bya Ceramic nk'amashanyarazi ya dielectric na metallic mu kubika umuriro w'amashanyarazi. Bikoreshwa cyane mu bikoresho by'ikoranabuhanga bikoreshwa n'abaguzi, itumanaho, ibikoresho by'ikoranabuhanga bikoresha imodoka, ndetse no mu kugenzura inganda, aho bikora imirimo y'ingenzi nko gutandukanya, kuyungurura, guhuza, guhuza imbaraga, no kubika ingufu.
Kugira ngo amashanyarazi akomeze kubika no gushyiraho uburyo bwo guhuza amashanyarazi n'insinga zo hanze, electrode ni igice cy'ingenzi cy'imiterere ya capacitor. Electrode z'icyuma zikwirakwizwa ku mpande zombi za dielectric dielectric cyangwa zigashyirwa hamwe n'insinga za dielectric mu nyubako nyinshi, hamwe zigakora imiterere y'ibanze ya capacitor. Iyo voltage ikoreshejwe, amashanyarazi ateranyirizwa kuri electrode ebyiri kandi agahuzwa n'insinga zo hanze binyuze mu nyubako ya electrode.
1. Kuki igiciro cya Electrode zisanzwe za Silver-Paste kuri Capacitors za Ceramic gikomeje kuzamuka?
Uburyo busanzwe bwo gukora electrode kuri capacitors za ceramic bukoresha uburyo bwo gucapa no gutwika ifeza. Ubusanzwe uburyo bugizwe no gutegura substrate ya ceramic, gucapa ifeza, kumisha, gucana mu bushyuhe bwinshi, kugenzura electrode, no gutunganya nyuma. Ubu buryo bumaze imyaka myinshi bukoreshwa cyane, hamwe n'uburyo bwa silver-paste bugezweho, ikoranabuhanga ryo gucapa ecran, uburyo bwo gucapa, na sisitemu zo gucana. Ibikoresho byayo byo gukora n'ibikorwa remezo biyifasha byarashyizweho neza, bifite imbogamizi nke ku ishyirwa mu bikorwa ry'umurongo w'umusaruro kandi bihura neza n'ibicuruzwa bifite imiterere itandukanye.
Muri icyo gihe, silver paste ikoresha ifu y'ifeza nk'igice cy'ingenzi gitwara amazi kandi igakora electrode binyuze mu buryo bungana na firime. Kubera iyo mpamvu, urwego rw'ifeza ruba rufite ubunini bungana, bigatuma silver ikoreshwa cyane kuri buri gicuruzwa.
Ubwo ibiciro bya feza byari biri hasi, ingaruka ku biciro bifitanye isano no gukoresha ifeza nyinshi ntizari zikomeye cyane. Ariko, uko ibiciro bya feza byakomeje kuzamuka mu gihe kirekire, iyi miterere y'ibiciro yakomeje kugaragara cyane. Hashingiwe ku mpuzandengo y'ibiciro bya feza byahinduwe RMB ku mwaka, igiciro cya feza cyari hafi RMB 1.9/g mu 2005, ugereranyije na RMB 9.2/g mu 2025, bigaragaza ko cyiyongereyeho inshuro zigera kuri 4.8 mu myaka 20 ishize.
Ku nganda zikora capacitor ya ceramic nyinshi, ingaruka z’izamuka ry’ibiciro bya feza zirushaho kuba ingenzi uko umusaruro wiyongera. Ikoreshwa rya feza riri hejuru kuri buri gice, rikuba kabiri n’umusaruro wa miliyoni, miliyoni mirongo, cyangwa ibindi bice birenga buri mwaka, rishobora gutuma habaho ikiguzi kinini cy’ibikoresho muri rusange. Iyo ibiciro bya feza bikomeje ku rwego rwo hejuru, inzira isanzwe kandi ihamye yo gukoresha electrode ya feza ihura n’igitutu gikomeye kiva ku biciro by’icyuma cy’agaciro.
Muri iki gihe, kugabanya ikoreshwa rya feza no kugabanya kwishingikiriza ku byuma by'agaciro ndetse n'ihindagurika ry'ibiciro byabyo byabaye ibintu by'ingenzi ku bakora capacitor ya ceramic.
2. Uburyo bwo kugabanya ikiguzi bwa Zhenhua Vacuum: Kuva ku "Gusimbuza umuringa ifeza" kugeza ku gukora ibintu byinshi buri gihe
Mu rwego rwo guhangana n’ikoreshwa ry’icyuma cy’agaciro kinini, intambwe nyinshi mu mikorere, no guhura n’ihindagurika ry’igiciro cya feza rijyanye na electrode zisanzwe zikoresha silver-paste, Zhenhua Vacuum yagiye isuzuma uburyo bwa magnetron sputtering bukoresha "umuringa usimbura silver" ku electrode za ceramic capacitor kandi yakurikiranye kugabanya ikiguzi binyuze mu kunoza imikorere no gusimbuza ibikoresho.
Aho kwishingikiriza ku gukora electrode isanzwe ikoresheje silver-paste, Zhenhua Vacuum ikoresha ikoranabuhanga ryo gusuka magnetron. Nk'uburyo bwo gushyira umwuka mu kirere (PVD), magnetron sputtering ishyira ibintu by'icyuma ku buso bwa ceramic mu kirere cy'isuku kugira ngo ikore electrode filime.
Ugereranyije n'uburyo busanzwe bwo gucapa hakoreshejwe ecran ya silver-paste, ubu buryo bukuraho intambwe nyinshi zisanzwe, harimo gutegura silver-paste, gucapa, kumisha, no gukoresha ubushyuhe bwinshi, bityo bigabanye uburyo bwo gukora no kugabanya uburyo bwo gukoresha no gukoresha intoki. Kubera ko silver paste n'ibikoresho byayo byo gufatanya na organic binder bidakenewe, ubu buryo bushobora kandi kugabanya imyuka ihumanya ikirere n'imyanda ituruka mu gukora electrode ishingiye kuri paste, bigatanga ubushobozi bwinshi bwo gukora neza no gukora mu buryo bwikora.
Mu buryo bw'ibikoresho, umuringa ukoreshwa nk'igikoresho cy'ingenzi gisimbura ifeza. Umuringa utanga amashanyarazi meza cyane mu gihe igiciro cyawo kiri hasi cyane ugereranyije n'icy'ifeza. Ibi bituma ikoreshwa ry'icyuma cy'agaciro rigabanuka cyane ku rwego rw'ibikoresho. Ku musaruro mwinshi, gusimbuza ibikoresho nk'ibyo bishobora kugabanya ikiguzi cy'ibikoresho bya electrode mu gihe bigabanya ingaruka z'ihindagurika ry'igiciro cya ifeza ku kiguzi rusange cy'inganda.
Ariko, gusimbuza ifeza umuringa si uguhindura ibikoresho bya electrode imwe ukabishyira ku yindi. Umuringa ushobora kwangizwa n’ubushyuhe bwinshi, kandi uburyo busanzwe bwo gucapa no gutwika umuringa busaba kugenzura neza uburyo bwo gushushanya umuringa, ikirere cyo kurasa, n’idirishya ryo gutunganya ibyuma. Ku rundi ruhande, gukoresha magnetron sputtering bituma ibyuma by’umuringa bishyirwa ahantu hatagaragara. Binyuze mu gushushanya ibyuma bifatanye, ibyuma biyobora amashanyarazi, n’ibindi bikoresho bikora filime, iyi gahunda ishobora kunoza uburyo filime ifatanye, ubucucike, n’imikorere y’amashanyarazi, bigatanga ubundi buryo bwo gushyira mu bikorwa "ifeza isimbura umuringa."
2.1 Kuva ku iterambere ry'imikorere kugeza ku musaruro mwinshi: Umuyoboro wa Zhenhua Vacuum uhora ukorwa n'imashini zikoresha amashanyarazi zigenda zisimburana zikora ku mpande ebyiri
Gukoresha icyuma cya Magnetron bishobora gutanga inzira ya tekiniki yo "gusimbura umuringa," ariko ku nganda zikora capacitor ya ceramic nyinshi, gukora ingero zitwikiriye gusa ntibihagije. Ikibazo cy'ingenzi ni ukugera ku musaruro muremure, uhamye kandi uhoraho.
Kugira ngo iki gisabwa gikemuke, Zhenhua Vacuum yateguye umurongo wo gukora magnetron uhora uhuza impande ebyiri wa electrode za ceramic capacitor, uhuza ikoranabuhanga ryo gusiga ifuru n'umusaruro wikora. Nyuma yo kwinjira mu murongo wo gukora, ibicuruzwa bihora byimurirwa hagati y'ibyumba bitandukanye byo gukora, mu gihe filime za electrode zishyirwa ku mpande zombi muri sisitemu imwe yo gukora. Ibi bigabanya gukenera guhindurirwa intoki, gupakira no gupakurura inshuro nyinshi, no gufata hagati y'ibikorwa hagati y'ibikorwa.
Ibikoresho bifata imiterere ihoraho y'umurongo wo gukora, bigatuma ibice bitandukanye bya filime, harimo n'ibice bifatanye cyangwa bisimburana n'ibice biyobora, bishyirwa muri sisitemu imwe ihujwe. Binyuze mu kohereza ibikoresho mu buryo bwikora, kugenzura neza uburyo bwo gukora, no gucunga neza uburyo bwo gukora, sisitemu irushaho kunoza ubugari bwa filime no kudahungabana mu gihe cyo gukora ibintu byinshi.
Iyi nzira y’imikorere nayo yagenzuwe igihe kirekire mu gukora ibintu byinshi. Mu 2012, Zhenhua Vacuum yahaye umukiriya umurongo wo gukora magnetron uhora uhindagurika ukoresheje electrode za ceramic capacitor. Kugeza mu 2026, umurongo wo gukora wamaze imyaka 14 uhoraho mu gukora ibintu byinshi, bitanga igenzura ry’igihe kirekire ry’uburyo ibikoresho byizewe, uburyo bwo gusiga irangi ku mpande ebyiri, ndetse n’uburyo bwo gukora ibintu byinshi hakoreshejwe magnetron “umuringa usimbura feza”.
Impinduka kuva kuri electrode zisanzwe za silver-paste kugera kuri "ifeza isimbura umuringa" ishingiye kuri magnetron si ugusimbuza ibikoresho gusa. Igaragaza uburyo bwo guhuza ibikoresho, inzira zo kubikuramo, n'uburyo bwo kubitunganya. Binyuze mu ikoranabuhanga rya magnetron sputtering n'umurongo wo gukora uhoraho ufite impande ebyiri, Zhenhua Vacuum yakuye igitekerezo cya "ifeza isimbura umuringa" ku gisubizo cya tekiniki ikakigeza ku musaruro uhamye kandi uhoraho.
Ku nganda zikora capacitor ya ceramic nini cyane, agaciro k’ubukungu ka "ifeza isimbura umuringa" gashobora kugaragara neza gusa iyo ikiguzi cy’ibikoresho cyagabanutse, inzira yo kubikora yoroshywa, kandi umusaruro urambye ukagerwaho icyarimwe.
-Iyi nkuru yasohotse nauruganda rukora ibikoresho byo gusiga irangi ry'umwuka Zhenhua Vacuum
