Njengoba izingxenye ze-elekthronikhi zithuthuka zibe yi-miniaturization kanye nokusebenza kwemvamisa ephezulu, ama-varistors ahlala eyingxenye ebalulekile yokuvikelwa kwe-overvoltage. Kungakhathaliseki ukuthi kumadivayisi ahlakaniphile, ama-elekthronikhi ezimoto, noma izinhlelo zokulawula zezimboni kanye namandla, ama-varistors asebenza njengabavikeli abaphambili ekukhuphukeni kwamandla kagesi. Ukuqinisekisa ukuthi asabela ngokushesha, ahlala isikhathi eside, futhi asebenza ngokuthembekile, ukusebenza akuxhomeki kuphela enkabeni ye-ceramic kodwa futhi—ngokubalulekile—ekhwalithini yokwelashwa kwendawo. Ikakhulukazi, ukugqoka kwe-vacuum sekuyisihluthulelo esiyinhloko sokukhiqizwa kwama-varistors anokwethenjelwa okuphezulu.
1. Yini Eyenziwa Yi-Varistor Ngempela?
Ngamagama alula, i-varistor iyi-resistor encike ku-voltage. Ukumelana kwayo kwehla kakhulu uma i-voltage esetshenzisiwe idlula umkhawulo othile, ngaleyo ndlela iphambukisa futhi ichithe amandla okukhuphuka ukuze kuvikelwe amasekethe angaphansi komfula. Lokhu kuziphatha okuzivumelanisa nezimo kwenza ama-varistor afaneleke kakhulu ekuvikeleni ukukhuphuka, ukuvikela umbani, kanye nokucindezelwa kwe-voltage yesikhashana.
Ngenxa yesikhathi sabo sokuphendula esisheshayo, usayizi omncane, kanye nezindleko eziphansi, ama-varistors asetshenziswa kabanzi kumadivayisi okuxhumana ngocingo, kuma-electronics abathengi, kuma-ECU ezimoto, kanye nasezinhlelweni zamandla avuselelekayo.
2. Kungani Ukwelashwa Komphezulu Kubaluleke Kangaka?
Nakuba ukusebenza okuyinhloko kwe-varistor kuvela ezintweni ze-ceramic ezisekelwe ku-zinc oxide, ukuthembeka kwesikhathi eside kuvame ukuncika ekhwalithini yesendlalelo sayo se-electrode. Ezisetshenzisweni zangempela, ama-varistor abhekana nokwanda kwamandla kagesi okuphindaphindiwe kanye nezimo zikagesi ezinzima. Ifilimu ye-electrode akumele ibonise kuphela ukuhanjiswa okuhle kakhulu kodwa futhi inikeze ukunamathela okuqinile, ukuzinza kokushisa, ukumelana nokugqwala, kanye nokuhambisana kahle ne-substrate ye-ceramic.
Ngamanye amazwi, ngisho nezinto zobumba ezinhle kakhulu zingasebenza kahle uma ungqimba lwensimbi engaphezulu luhluleka. Ngakho-ke, ukufakwa kwe-electrode kanye nokwelashwa kwendawo sekubaluleke kakhulu ekukhiqizweni kwe-varistor yesizukulwane esilandelayo.
3. Ubuchwepheshe Bendabuko Be-Electrode kanye Nemikhawulo Yabo
Njengamanje, ukwenziwa kwe-varistor electrode kuncike kakhulu ekusinteni i-silver paste, i-electroplating, kanye nokuphrinta kwesikrini. Kodwa-ke, lezi zindlela ezivamile zibhekene nezinselele ezikhulayo:
Ukunamathela okungaguquki: Ezindaweni ezingaphansi kwe-ceramic ezingasebenzi, ukuxebuka, ukuhlukanisa, noma ukuqhekeka kungenzeka.
Ukufana okungekuhle kwefilimu: Kuthinta ukuhambisana kukagesi futhi kunciphise isivuno sonke.
Ukukhathazeka Ngezemvelo: Ukufaka i-electroplating kuhilela izinsimbi ezisindayo kanye nemfucuza yamakhemikhali, okwenza kube nzima ukuhambisana nezindinganiso zemvelo.
Ukukhuliswa okulinganiselwe: Kunzima ukuhlangabezana nezidingo zezingxenye ezincane kanye namajiyometri aqondile.
Le mikhawulo iqhubela imboni ubuchwepheshe be-electrode obunembile, obuhlanzekile, nobunwebekayo.
4. Ukugqoka Nge-Vacuum: Indlela Entsha Yokukhiqiza Nge-Varistor
Ukuze kuxazululwe la maphuzu obuhlungu, i-magnetron sputtering—uhlobo lobuchwepheshe bokumboza nge-vacuum—ivele njengendlela ekhethwayo yokufaka i-electrode kuma-varistors.
Ngaphansi kwe-vacuum ephezulu, ama-ion anamandla aphezulu ahlasela ithagethi yensimbi, okwenza ama-athomu akhishwe futhi afakwe kwi-substrate. Le nqubo iveza ungqimba lwefilimu oluqinile, olufanayo, futhi olunamathela kakhulu olunezinzuzo eziningana ezibalulekile:
Ukunamathela okuqinile kanye nesakhiwo esincane, okuqinisekisa ukuqina ngaphansi kwezimo zokukhuphuka okuphindaphindiwe.
Ukufana okuhle kakhulu kobukhulu befilimu kanye nokuphindaphinda kwenqubo, kulungele ukukhiqizwa okuphezulu nokungaguquguquki okuphezulu.
Inqubo eyomile nehlanzekile, engenazo izinto ezikhipha ukungcola kwamakhemikhali, ehambisana neziqondiso ze-RoHS kanye ne-REACH.
Ukuhambisana nezimo eziyinkimbinkimbi, ezifanele izingxenye ze-elekthronikhi zohlobo lwe-chip kanye nezingajwayelekile.
Namuhla, ukugqoka nge-vacuum kuye kwamukelwa kabanzi ekukhiqizweni kwama-varistors aphezulu, ama-MLCC, ama-resistors e-thin-film, kanye nezinye izingxenye ze-elekthronikhi ezinembile.

Isiphetho: Ukwelashwa Komphezulu Kuchaza Ukuthembeka Kwesikhathi Esizayo
Kuma-varistors, ukuthembeka kuqala ebusweni. Njengoba amazinga enyuka futhi ukwenziwa kube kuncane, ukukhetha ukwelashwa kwendawo okusebenzayo kakhulu futhi okunobungani nemvelo sekuba yinto ebalulekile kubakhiqizi bezingxenye ze-elekthronikhi.
Ukugqoka nge-vacuum kungaphezu nje kokuthuthukiswa kobuchwepheshe—kuwushintsho kwifilosofi yokukhiqiza.
