Giovanni D'Amore akakurukura nezvekushandiswa kweimpedance analyzer uye nyanzvi zvigadziriso kuratidza dielectric uye magineti zvinhu.
Isu tajaira kufunga nezvekufambira mberi kwehunyanzvi kubva kuzvizvarwa zvemodhi yenharembozha kana semiconductor kugadzira nzira nodes.Izvi zvinopa kufambira mberi kunobatsira asi kusinganzwisisike mukugonesa matekinoroji (akadai sendima yesainzi yezvinhu).
Chero ani akabvisa CRT TV kana kubatidza magetsi ekare achaziva chinhu chimwe: Haugone kushandisa zvikamu zvezana ramakore rechi20 kugadzira zvemagetsi zvezana ramakore rechi21.
Semuyenzaniso, kukurumidza kufambira mberi mune zvekushandisa sainzi uye nanotechnology yakagadzira zvinhu zvitsva zvine hunhu hunodiwa kuvaka yakakwira-density, yepamusoro-performance inductors uye capacitor.
Kugadziridzwa kwemidziyo inoshandisa zvinhu izvi kunoda kuyerwa kwakaringana kwemagetsi uye magineti zvivakwa, senge mvumo uye permeability, pamusoro pehuwandu hwekushanda kwema frequency uye tembiricha.
Dielectric zvinhu zvinoita basa rinokosha muzvikamu zvemagetsi zvakadai se capacitors uye insulators.Dielectric nguva dzose yechinhu inogona kugadziriswa nekudzora kuumbwa kwayo uye / kana microstructure, kunyanya ceramics.
Izvo zvakakosha kuyera iyo dielectric zvimiro zvezvitsva zvitsva kutanga kwechikamu chekusimudzira kutenderera kufanotaura kuita kwavo.
Zvinhu zvemagetsi zvezvinhu zve dielectric zvinoratidzirwa nemvumo yavo yakaoma, iyo inosanganisira zvikamu zvechokwadi uye zvekufungidzira.
Chikamu chaicho che dielectric constant, iyo inonziwo dielectric constant, inomiririra kukwanisa kwechinhu kuchengetedza simba kana ichiiswa pasi pemagetsi. , izvo zvinoita kuti zvive zvakakosha kune yakakwirira-density capacitors.
Zvishandiso zvine yakaderera dielectric constants zvinogona kushandiswa seanobatsira insulators mumasaini ekufambisa masisitimu, chaizvo nekuti haagone kuchengetedza huwandu hukuru hwesimba, nekudaro kuderedza kunonoka kuparadzira chiratidzo kuburikidza nechero waya dzakadzivirirwa navo.
Chikamu chekufungidzira chemvumo yakaoma inomiririra simba rakasvibiswa nezvinhu zve dielectric mumunda wemagetsi.Izvi zvinoda kutungamirirwa kwakanyatsonaka kuti usabvisa simba rakawanda mumidziyo yakadai se capacitors yakagadzirwa nezvinhu izvi zvitsva zve dielectric.
Kune nzira dzakasiyana-siyana dzekuyera dielectric constant.Iyo parallel plate nzira inoisa zvinhu pasi pekuedzwa (MUT) pakati pema electrode maviri.Equation inoratidzwa mumufananidzo 1 inoshandiswa kuyera impedance yezvinhu uye kuishandura kune yakaoma permittivity, iyo. inoreva kukora kwezvinhu uye nzvimbo uye dhayamita ye electrode.
Iyi nzira inonyanya kushandiswa pakuyera kuderera kwehuwandu.Kunyange zvazvo nheyo yacho iri nyore, kuyerwa kwakarurama kwakaoma nekuda kwezvikanganiso zvekuyera, kunyanya kune zvishoma-kurasikirwa kwezvinhu.
Kubvumirwa kwakaoma kunosiyana nehuwandu, saka inofanira kuongororwa pahuwandu hwekushanda.Pakukwira kwepamusoro, kukanganisa kunokonzerwa nechiyero chekuyera kuchawedzera, zvichiita kuti zviyero zvisina kururama.
Iyo dielectric material test fixture (yakadai seKeysight 16451B) ine ma electrode matatu.Vaviri vavo vanoumba capacitor, uye chechitatu inopa electrode inodzivirira.Iyo inodzivirira electrode inofanirwa nokuti kana nzvimbo yemagetsi inotangwa pakati pemagetsi maviri, chikamu che munda wemagetsi uchayerera kuburikidza neMUT yakaiswa pakati pavo (ona Mufananidzo 2).
Kuvapo kwemupendero wemunda uyu kunogona kutungamirira kuchiyero chisina kururama che dielectric constant yeMUT.Iyo electrode yekudzivirira inotora ikozvino inoyerera kuburikidza nemunda wemupendero, nokudaro ichivandudza kuyerwa kwechiyero.
Kana iwe uchida kuyera dielectric properties yechinhu, zvakakosha kuti iwe unongoyera zvinhu chete uye hapana chimwe chinhu.Nechikonzero ichi, zvakakosha kuve nechokwadi kuti sampu yezvinyorwa yakanyatsoputika kuti ibvise chero mapeji emhepo pakati payo nemhepo. electrode.
Pane nzira mbiri dzekuzadzisa izvi.Yekutanga ndeyekushandisa maelectrodes efirimu akaonda pamusoro pezvinhu zvinofanira kuongororwa.Yechipiri ndeyokuwana mvumo yakaoma kuburikidza nekuenzanisa kukwanisa pakati pe electrode, iyo inoyerwa muhupo uye kusavapo. zvezvinhu.
Electrode yevarindi inobatsira kuvandudza kuyerwa kwechiyero panguva yakaderera, asi inogona kukanganisa nzvimbo yemagetsi pamhepo yakakwira kubatsira kubvisa mhedzisiro yefringing capacitance.
Zvikanganiso zvakasara zvinokonzerwa nekugadzirisa uye analyzers zvinogona kuderedzwa nedunhu rakazaruka, pfupi pfupi uye muripo wemutoro.Vamwe impedance analyzers vakavaka-mune basa iri rekubhadhara, rinobatsira kuita zviyero zvakarurama pamusoro pehuwandu hwakawanda.
Kuongorora kuti zvinhu zvezvinhu zve dielectric zvinoshanduka sei nekushisa zvinoda kushandiswa kwemakamuri anodzora kupisa uye tambo dzisingadziviriri kupisa.Vamwe vaongorori vanopa software yekudzora sero rinopisa uye tambo inodzivirira kupisa.
Kufanana nemidziyo ye dielectric, ferrite zvinhu zviri kuvandudza zvishoma nezvishoma, uye zvinoshandiswa zvakanyanya mumidziyo yemagetsi senge inductance components uye magineti, pamwe chete nezvikamu zve transformers, magineti magineti absorbers uye suppressors.
Hunhu hwakakosha hwezvinhu izvi zvinosanganisira kupenya uye kurasikirwa kwavo panguva dzakakosha dzekushanda.An impedance analyzer ine magnetic material fixture inogona kupa zviyero zvakarurama uye zvinodzokororwa pamusoro pehuwandu hwehuwandu.
Sezvinoita dielectric zvinhu, kupindira kwezvinhu zvemagineti chinhu chakaomarara chinoratidzwa muzvikamu zvechokwadi uye zvekufungidzira.Izwi chairo rinomiririra kugona kwechinhu kuita magineti flux, uye izwi rekufungidzira rinomiririra kurasikirwa mune izvo zvinhu.Zvinhu zvine magineti akakwira anogona inoshandiswa kuderedza ukuru uye uremu hwemagineti system.Chikamu chekurasikirwa kwemagnetic permeability chinogona kuderedzwa kuti chinyatsoshanda mumashandisirwo akadai semashanduri, kana kukwidziridzwa mumashandisirwo akadai sekudzivirira.
Iyo yakaoma permeability inotarirwa ne impedance yeinductor yakagadzirwa nezvinhu.Muzviitiko zvakawanda, inosiyana nehuwandu, saka inofanira kuonekwa pahuwandu hwekushanda. fixture.Kune zvinhu zvakaderera-kurasikirwa, chikamu chekona ye impedance inokosha, kunyange zvazvo kururamisa kwechiyero chechikamu kunowanzove kusina kukwana.
Magnetic permeability zvakare inoshanduka netembiricha, saka kuyerwa kwegadziriro inofanirwa kukwanisa kunyatso ongorora hunhu hwetembiricha pane yakakura frequency renji.
Iyo yakaoma permeability inogona kutorwa nekuyera iyo impedance yemagineti zvinhu.Izvi zvinoitwa nekuputira dzimwe waya kutenderedza zvinhu uye kuyera iyo impedance inoenderana nekuguma kwewaya. Zvigumisiro zvinogona kusiyana zvichienderana nekuti waya yakakuvadzwa sei uye kupindirana. yemagnetic field nenzvimbo yakapoteredza.
Iyo magnetic material test fixture (ona Figure 3) inopa imwechete-turn inductor iyo yakatenderedza toroidal coil yeMUT. Iko hakuna kuvuza kunoyerera mune imwechete-turn inductance, saka iyo magineti mune inogadziriswa inogona kuverengerwa ne electromagnetic theory. .
Kana ichishandiswa pamwe chete ne impedance / material analyzer, chimiro chakareruka cheiyo coaxial fixture uye toroidal MUT inogona kunyatsoongororwa uye inogona kuwana yakafara frequency kufukidzwa kubva 1kHz kusvika 1GHz.
Iko kukanganisa kunokonzerwa nechiyero chekuyera kunogona kubviswa kusati kwayera.Kukanganisa kunokonzerwa ne impedance analyzer inogona kugadziriswa kuburikidza nekugadzirisa kukanganisa kwemaawa matatu.Pakukwira kwepamusoro, kuderera-kurasikirwa capacitor calibration kunogona kuvandudza chikamu chekona.
Iyo gadziriso inogona kupa imwe sosi yekukanganisa, asi chero yasara inductance inogona kubhadharwa nekuyera gadziriso pasina MUT.
Sezvakaita dielectric kuyerwa, kamuri yetembiricha uye tambo dzinodzivirira kupisa zvinodikanwa kuti uongorore tembiricha yehunhu hwemagineti.
Nharembozha dziri nani, masisitimu erubatsiro emutyairi epamusoro uye malaptops anokurumidza zvese zvinotsamira pakuenderera mberi kwehunyanzvi hwakasiyana siyana.Tinokwanisa kuyera kufambira mberi kwemasemiconductor process node, asi nhevedzano yehunyanzvi hwekutsigira huri kusimukira nekukurumidza kuti maitiro matsva aya avepo. kushandiswa.
Kufambira mberi kwezvino muzvinhu zvesainzi uye nanotechnology kwakaita kuti zvikwanisike kugadzira zvinhu zvine dielectric zviri nani uye magineti maitiro kupfuura kare.Zvisinei, kuyera kufambira mberi uku inzira yakaoma, kunyanya nekuti hapana chikonzero chekudyidzana pakati pezvishandiso uye zvigadziriso pazviri. vakaiswa.
Zviridzwa zvakafungwa zvakanaka uye zvigadziriso zvinogona kukunda mazhinji ematambudziko uye kuunza yakavimbika, inodzokororwa uye inoshanda dielectric uye magineti zvinhu zviyero zvepfuma kune vashandisi vasina hunyanzvi chaihwo mundima idzi.Chigumisiro chinofanira kunge chiri kukurumidza kutumirwa kwezvinhu zvemberi mukati mese. iyo yemagetsi ecosystem.
