Sezvo zvikamu zvemagetsi zvichichinja kuita kuti zvive zvishoma uye kushanda kwema frequency akawanda, varistors dzinoramba dziri chinhu chakakosha chekudzivirira overvoltage. Ingave iri mumidziyo yakangwara, zvemagetsi zvemotokari, kana masisitimu ekutonga eindasitiri uye esimba, varistors dzinoshanda sedziviriro yepamberi kubva pakukwira kwemagetsi. Kuti ive nechokwadi chekuti dzinopindura nekukurumidza, dzinogara kwenguva refu, uye dzinoshanda zvakavimbika, mashandiro adzo haangotsamiri pa ceramic core chete asiwo - zvakanyanya - pamhando yekurapa pamusoro. Kunyanya, vacuum coating yave chinhu chakakosha pakugadzira varistors yakavimbika zvikuru.
1. Chii Chinomboitwa neVaristor Chaizvo?
Muchidimbu, varistor iresistor inoenderana nemagetsi. Kudzivirira kwayo kunodzikira zvakanyanya kana voltage inoshandiswa yadarika chiyero chakati, nokudaro ichitsausa uye ichibvisa simba rekukwira kwemhepo kudzivirira maseketi ari pasi. Maitiro aya ekuzvigadzirisa anoita kuti varistor ive yakakodzera kudzivirira kukwira kwemhepo, kudzivirira mheni, uye kudzvinyirira voltage kwenguva pfupi.
Nekuda kwenguva yavo yekupindura nekukurumidza, saizi yavo diki, uye mutengo wakaderera, varistors dzinoshandiswa zvakanyanya mumidziyo yekukurukurirana, zvigadzirwa zvemagetsi zvevatengi, maECU emotokari, uye masisitimu esimba rinogona kudzokororwa.
2. Sei Kurapa Pamusoro Kwakakosha Kwazvo?
Kunyange zvazvo kushanda kwepakati kwevaristor kuchibva pazvinhu zveceramic zvakagadzirwa ne zinc oxide, kuvimbika kwenguva refu kunowanzoenderana nemhando ye electrode layer yayo. Mukushandiswa kwenyika chaiyo, varistors vanosangana ne voltage surges inodzokororwa uye mamiriro emagetsi akaomarara. Firimu re electrode harifanirwe kungoratidza conductivity yakanaka chete asiwo kupa kunamira kwakasimba, kugadzikana kwekupisa, kuramba ngura, uye kuenderana kwakakwana ne ceramic substrate.
Nemamwe mashoko, kunyangwe zvinhu zveceramic zvakanakisisa zvinogona kushanda zvisina kunaka kana simbi yepamusoro ikatadza kushanda. Saka, kuisa ma electrode uye kugadzirisa pamusoro zvave zvakakosha mukugadzirwa kwevaristor yechizvarwa chinotevera.
3. Matekinoroji Emagetsi Echinyakare Nekuganhurirwa Kwawo
Parizvino, kugadzirwa kwema electrode evaristor kunonyanya kushandiswa pakugadzira silver paste sintering, electroplating, uye screen printing. Zvisinei, nzira idzi dzechinyakare dzinosangana nematambudziko ari kukura:
Kubatana kusina kuenderana: Pazvinhu zvisina kusimba zveceramic, kukwesha, kubvisa zvidimbu, kana kutsemuka zvinogona kuitika.
Kusafanana zvakanaka kwefirimu: Kunokanganisa kuenderana kwemagetsi uye kunoderedza goho rose.
Zvinonetsa Nezvezvakatipoteredza: Kuisa masimbi anorema nemarara emakemikari mumagetsi kunosanganisira kuita kuti zviome kutevedzera mitemo yezvakatipoteredza.
Kukwanisa kukura zvishoma: Zvakaoma kusangana nezvinodiwa nezvinhu zvidiki uye hunyanzvi hwemajiometri.
Zvipingamupinyi izvi zviri kutungamira indasitiri iyi kune matekinoroji emagetsi akarurama, akachena, uye anogona kukura.
4. Kuvhara Vacuum: Nzira Itsva Yekugadzira Varistor
Kuti tigadzirise marwadzo aya, magnetron sputtering—rudzi rwetekinoroji yekuvhara vacuum—yave nzira inonyanya kufarirwa yekuisa electrode pavaristors.
Pasi pemvura ine simba rakawanda, maion ane simba rakawanda anorova chinangwa chesimbi, zvichiita kuti maatomu abudiswe oiswa pamusoro pechinhu chacho. Maitiro aya anoita kuti firimu rive rakakora, rakafanana, uye rinonamatira zvakanyanya rine zvakanakira zvakawanda:
Kunamatira kwakasimba uye chimiro chakabatana, zvichiita kuti igare kwenguva refu kana ichidzokororwa.
Kuenzana kwakanaka kweukobvu hwefirimu uye kudzokorora maitiro, zvakanakira kugadzirwa kwepamusoro-soro uye kwakasimba.
Maitiro akaoma uye akachena, asina makemikari anobuda, anoenderana nemirairo yeRoHS neREACH.
Inoenderana nemaumbirwo akaomarara, akakodzera zvikamu zvemagetsi zvemhando yechip uye zvisina kujairika.
Nhasi, kuputira vacuum kwave kushandiswa zvakanyanya mukugadzira varistors dzemhando yepamusoro, MLCCs, thin-film resistors, nezvimwe zvikamu zvemagetsi zvine hungwaru.

Zvakanakira Midziyo:
-Kudzora zvizere otomatiki kuburikidza nemakombiyuta eindasitiri, kusanganisira manejimendi yekubika, kutarisa panguva chaiyo, uye kuongororwa kuri kure.
-Sisitimu yekubata yakabatana yekufambisa otomatiki workpiece uye kushanda nguva dzose.
-Magadzirirwo echinangwa akagadziridzwa uye ane mashandisirwo akawanda ezvinhu uye akafanana zvakanaka.
-Ionization yepamusoro uye sisitimu yekusimbisa pamusoro kuti iwedzere kunamira kwefirimu uye kufanana kwekuputira.
Mashandisirwo: Machip capacitors, matinji efirimu, nezvimwe zvikamu zvemagetsi zvinoiswa pamusoro.
Mhedziso: Kurapa Pamusoro Kunotsanangura Kuvimbika Kweramangwana
Kune varistors, kuvimbika kunotangira pamusoro. Sezvo mwero uchikwira uye miniaturization ichikura, kusarudza mushonga wepamusoro unoshanda zvakanaka uye usingakuvadzi nharaunda kwave kuva chinhu chakakosha kune vagadziri vezvikamu zvemagetsi.
Kuputira vacuum hakusi kungovandudza tekinoroji chete—kuchinja kwepfungwa dzekugadzira zvinhu.
ZhenHua Vacuum icharamba ichigadzira michina yekuputira vacuum uye mhinduro dzekugadzirisa dzakagadzirirwa indasitiri yemagetsi, zvichibatsira vatengi kuwana mikana yekukwikwidzana mukushanda uye mutengo.
