Ama-Varistors, ama-thermistors, nama-capacitor e-ceramic asetshenziswa kabanzi ezintweni zasendlini, kuma-electronics abathengi, imishini yamandla, ezimotweni zamandla amasha, imishini yokuxhumana, kanye nezinhlelo zokulawula zezimboni, lapho enza khona imisebenzi efana nokuvikela isekethe, ukuzwa izinga lokushisa, ukugcina amandla, kanye nokuhlunga.
Izakhiwo zokusebenza ze-ceramics ze-elekthronikhi zinqunywa kakhulu yizakhiwo zazo zezinto, izinhlelo zokusebenzisa izidakamizwa, kanye nezinqubo zokuhlanza. I-ceramics ze-zinc oxide (ZnO) zibonisa izici ze-varistor futhi ngenxa yalokho zisetshenziswa ekwenziweni kwe-varistor, lapho ziguqula khona amandla okushisa lapho kwenzeka i-overvoltage yesikhashana. Ezinye izinto ze-oxide ceramics kanye nezinto ezisekelwe ku-barium titanate zingasetshenziswa ukukhiqiza ama-thermistors, kuyilapho izinto ze-dielectric ceramics ezifana ne-barium titanate kanye ne-calcium titanate zisetshenziswa kabanzi kuma-capacitor e-ceramic.
Nakuba lezi zinto zithola izakhiwo zazo ze-varistor, i-thermistor, noma i-dielectric ngemuva kokwakheka nokushiswa, zihlala ziyimizimba ye-ceramic esebenzayo futhi azikakwazi ukuhlanganiswa ngqo kumasekethe kagesi. Ukuze zibe izingxenye ze-elekthronikhi ezingafakwa kumabhodi wesekethe aphrintiwe, ama-electrode esiliva kudingeka akheke ezindaweni zawo eziphezulu nezingezansi. Ngakho-ke, ukwakheka kwe-electrode yesiliva kuyinqubo ebalulekile ekukhiqizweni kwezingxenye ze-elekthronikhi ze-ceramic.
1. Kungani I-Electronic Ceramics Idinga I-Silver Electrode Coating?
Ukugqoka i-electrode yesiliva ye-ceramics kagesi kuhilela ukwakha ama-electrode okuqhuba ezindaweni eziphezulu nezingezansi ze-substrate ye-ceramic, okuhlinzeka nge-interface yensimbi eqinile yokusetshenziswa kwe-voltage, ukuqhutshwa kwamanje, kanye nokunamathiselwa kwe-lead. Ngemva kokwakheka kwe-electrode, imizimba ye-ceramic ivame ukuhlangana ne-lead bonding, encapsulation, kanye nokuhlolwa kukagesi ngaphambi kokuhlanganiswa kube yi-varistors eqediwe, ama-thermistors, noma ama-capacitor e-ceramic.
Ama-electrode e-ceramic kagesi ngokuvamile asebenzisa isakhiwo se-metallization esinezingqimba eziningi. I-Ti noma i-NiCr ingasetshenziswa njengengqimba yokunamathela ukuze kuthuthukiswe ukubopha okuphakathi kwe-coating kanye ne-ceramic substrate, kuyilapho i-Cu noma i-Ag ingafakwa njengengqimba ephezulu yokuqhuba ukuze kuhlangatshezwane nezidingo zokuqhuba kagesi kanye nokushintshwa kwe-solder.
Eziningi zezicelo, izindawo eziphezulu nezingezansi kuphela ze-ceramic kagesi ezifakwe insimbi, kuyilapho izindawo eziseceleni kumele zihlale zifakwe ugesi. Ubukhulu befilimu obungalingani, ama-pinhole, noma ukushiywa kwengubo yendawo kungabangela ukumelana okungazinzile kokuxhumana, ukungakwazi ukunamathela kahle, kanye nokuphambuka kokusebenza kukagesi. Ukugqoka ezindaweni eziseceleni kungase futhi kuvimbele ama-electrode aphezulu nangaphansi ngogesi, kuyilapho amandla okunamathela anganele angaholela ekuhlukaniseni ifilimu. Ngakho-ke, ukugqoka kwe-electrode yesiliva ye-ceramics kagesi kumele kufinyelele ibhalansi phakathi kokufana kobukhulu befilimu, ubuningi befilimu, amandla okunamathela, kanye nokulawula okunembile kwendawo yokufaka.
2. Izinselele Zezindleko Zezinto Nezinqubo Zokwenziwa Kwensimbi Kwesiliva Okuvamile
Eminye imikhiqizo ye-ceramic kagesi isebenzisa ukuphrinta kwesikrini sokunamathisela isiliva okulandelwa ukudubula, noma i-wet chemical silver plating, ukwakha ama-electrode esiliva. Ubukhulu obujwayelekile be-silver-layer bungaba ngu-20 μm, yize ubukhulu bangempela bunqunywa ngumkhiqizo kanye nezidingo zenqubo ethile. Ukuphrinta nokudubula kwesikrini sokunamathisela isiliva ngokuvamile kuhilela ukuhlanza indawo, ukuphrinta isikrini, ukulinganisa nokomisa, ukudubula, kanye nokuhlola. I-wet chemical silver plating ngokuvamile ihlanganisa ukwelashwa kwangaphambili, ukuzwela kanye nokusebenza, i-chemical silver plating, ukuhlanza, ukomisa, kanye nokuhlola.
Kusukela ngo-2026, amanani esiliva akhuphuke kakhulu futhi ahlala emazingeni aphezulu, okwandisa kakhulu umthelela wezindleko zezinto zesiliva ekukhiqizweni kwama-electrode e-ceramic kagesi. Izingqimba zesiliva ezijiyile ezikhiqizwa ukuphrinta nokushisa isiliva okujwayelekile noma izinqubo zokufaka isiliva ezimanzi zingabangela ukusetshenziswa kwesiliva okukhulu. Ekukhiqizweni okuphezulu, lokhu kukhulisa ngqo izindleko zezinto ngengxenye ngayinye.
Ngaphezu kwalokho, izigaba zokomisa nezokushisa okuphezulu ezidingekayo ekuphrinteni i-silver paste, kanye nezigaba zokwelashwa kwangaphambi kwesikhathi, ukuzwela kanye nokusebenza, ukuhlanza, nokomisa ezihilelekile ekufakweni kwe-silver plating emanzi, kwandisa ukusetshenziswa kwamandla, isikhathi sokuhola ekukhiqizeni, kanye nezindleko zokulawula inqubo.
3. I-Vacuum Magnetron Sputtering Yokulinganisela Ukusebenza Kwefilimu Nokulawula Izindleko
Ukuphalaza nge-vacuum magnetron kuyinqubo ye-PVD lapho izinhlayiya ezinamandla aphezulu ziqhumisa khona ithagethi yensimbi ngaphansi kwe-vacuum, okubangela ukuthi ama-athomu aqondiwe aphalazeke bese efakwa ebusweni be-ceramic ukuze kwakheke ifilimu yensimbi efanayo neqinile.
Ngokwezidingo ezithile zomkhiqizo, i-electrode ingasebenzisa isakhiwo esinezingqimba eziningi esakhiwe ungqimba lokunamathela lwe-Ti noma i-NiCr oluhlanganiswe nongqimba oluqhuba i-Cu noma i-Ag, kanti ubukhulu befilimu bulawulwa cishe ku-6–7 μm. Uma kuqhathaniswa nobukhulu besiliva obujwayelekile obungaba ngu-20 μm, le ndlela inganciphisa ubukhulu besiliva obungadingekile kanye nokusetshenziswa kwensimbi eyigugu, ngaleyo ndlela yehlise izindleko zezinto zokwakha ekukhiqizweni okuphezulu.
Inqubo yokumboza i-vacuum ingenziwa lula ibe ukuhlanza nokulayisha, ukufaka i-vacuum, kanye nokuhlola, ukunciphisa izigaba zenqubo njengokushiswa kwe-binder, ukudubula okushisa okuphezulu, kanye nokwelashwa ngamakhemikhali amaningi amanzi. Kuhlanganiswe nokulawulwa okunembile kokujiya kwefilimu kanye nezinto zokufihla ezizinikele, inqubo ingathuthukisa ukuhambisana kwamafilimu afakwe ezindaweni eziphezulu nezingezansi ngenkathi igcina izindawo eziseceleni zifakwe ugesi.
