Njengoko izinto ze-elektroniki zitshintsha zibe yi-miniaturization kunye nokusebenza rhoqo, ii-varistors zihlala ziyinxalenye ebalulekileyo yokukhusela i-overvoltage. Nokuba zikwizixhobo ezikrelekrele, ii-elektroniki zeemoto, okanye iinkqubo zolawulo lwamashishini kunye namandla, ii-varistors zisebenza njengabakhuseli abaphambili ngokuchasene nokunyuka kwamandla ombane. Ukuqinisekisa ukuba ziphendula ngokukhawuleza, zihlala ixesha elide, kwaye zisebenza ngokuthembekileyo, ukusebenza akuxhomekanga kuphela kwisiseko se-ceramic kodwa - ngokubalulekileyo - kumgangatho wonyango lomphezulu. Ngokukodwa, i-vacuum coating ibe yinto ephambili enika amandla emveliso ye-varistors enokuthembeka okuphezulu.
1. Yintoni kanye kanye eyenziwa yiVaristor?
Ngamazwi alula, i-varistor yi-resistor exhomekeke kwi-voltage. Ukumelana kwayo kuyehla kakhulu xa i-voltage esetyenzisiweyo idlula umda othile, ngaloo ndlela ijika kwaye ichitha amandla okuhamba ukuze ikhusele iisekethe ezisezantsi. Olu hlobo lokuziphatha oluzilungelelanisayo lwenza i-varistor ibe yeyona ifanelekileyo yokukhusela ukuhamba, ukukhusela umbane, kunye nokuncitshiswa kwe-voltage yesikhashana.
Ngenxa yexesha labo lokuphendula ngokukhawuleza, ubungakanani obuncinci, kunye nexabiso eliphantsi, ii-varistors zisetyenziswa kakhulu kwizixhobo zonxibelelwano, kwii-elektroniki zabathengi, kwii-ECU zeemoto, nakwiinkqubo zamandla avuselelekayo.
2. Kutheni Unyango Lomphezulu Lubaluleke Kangaka?
Nangona ukusebenza okuphambili kwe-varistor kuvela kwizinto zeseramikhi ezisekwe kwi-zinc oxide, ukuthembeka kwexesha elide kudla ngokuxhomekeke kumgangatho womaleko wayo we-electrode. Kwizicelo zehlabathi lokwenyani, ii-varistors zijongana nokunyuka kwamandla ombane okuphindaphindiweyo kunye neendawo zombane ezinzima. Ifilimu ye-electrode akufuneki ibonise kuphela ukuqhuba kakuhle kodwa ikwabonelela ngokunamathela okuqinileyo, uzinzo lobushushu, ukumelana nokugqwala, kunye nokuhambelana okuphezulu ne-substrate yeseramikhi.
Ngamanye amazwi, kwanezona zinto zibalaseleyo zeseramikhi zinokusebenza kakubi ukuba umaleko wesinyithi esingaphezulu uyasilela. Ngenxa yoko, ukufakwa kwe-electrode kunye nonyango lomphezulu kuye kwaba yinto ebalulekileyo ekuvelisweni kwe-varistor kwisizukulwana esilandelayo.
3. Iiteknoloji ze-Electrode zeMveli kunye nemida yazo
Okwangoku, ukwenziwa kwe-varistor electrode kuxhomekeke kakhulu ekutshiseni i-silver paste, ukufakelwa kwe-electroplating, kunye nokuprinta kwesikrini. Nangona kunjalo, ezi ndlela zemveli zijongene nemingeni ekhulayo:
Ukunamathela okungaguqukiyo: Kwizinto ezingasetyenziswanga zeseramikhi, ukuxobuka, ukwahlulahlula, okanye ukuqhekeka kunokwenzeka.
Ukufana okungekho semgangathweni kwefilimu: Kuchaphazela ukuhambelana kombane kwaye kunciphisa isivuno ngokubanzi.
Iingxaki zokusingqongileyo: Ukufakelwa kwe-electroplating kubandakanya isinyithi esinzima kunye nenkunkuma yamakhemikhali, nto leyo eyenza kube nzima ukuthotyelwa kwemigangatho yokusingqongileyo.
Ukukwazi ukukhulisa izinto kancinci: Kunzima ukuhlangabezana neemfuno zezinto ezincinci kunye nejometri ezicwangcisiweyo.
Ezi mingcele ziqhubela eli shishini kubuchwepheshe be-electrode obuchanekileyo, obucocekileyo, nobunokwandiswa.
4. Ukwaleka ngeVacuum: Indlela eNtsha yokwenziwa kweVaristor
Ukujongana nezi ndawo zibuhlungu, i-magnetron sputtering—uhlobo lwetekhnoloji yokugquma nge-vacuum—ivele njengendlela ekhethwayo yokufaka i-electrode kwi-varistors.
Phantsi kwe-vacuum ephezulu, ii-ion ezinamandla aphezulu zihlasela ithagethi yesinyithi, nto leyo ebangela ukuba ii-athomu zikhutshwe zize zifakwe kwi-substrate. Le nkqubo ivelisa umaleko wefilimu oxineneyo, ofanayo, nonamathelayo kakhulu onezibonelelo ezininzi ezibalulekileyo:
Ukunamathela okuqinileyo kunye nolwakhiwo oluncinci, okuqinisekisa ukuqina phantsi kweemeko zokuntywila okuphindaphindiweyo.
Ukufana okugqwesileyo kobukhulu befilimu kunye nokuphindaphinda kwenkqubo, ilungele imveliso ephezulu, ehambelanayo.
Inkqubo eyomileyo necocekileyo, engenazo iikhemikhali ezimdaka, ehambelana nemiyalelo yeRoHS kunye neREACH.
Ukuhambelana neemilo ezintsonkothileyo, ezifanelekileyo kwiinxalenye ze-elektroniki eziluhlobo lwe-chip kunye nezingaqhelekanga.
Namhlanje, i-vacuum coating yamkelwe ngokubanzi kwimveliso yee-varistors eziphezulu, ii-MLCC, ii-resistors zefilimu encinci, kunye nezinye izinto ze-elektroniki ezichanekileyo.
