Zvikonzero zvekutadza kwechigamba simba inductor| GETWELL

Ndezvipi zvikonzero zvinokanganisa inductance kukundikana kwechigamba? Nhasi, ndabatanidza zvimwe zvine chekuita nereferensi yako.

Zvikonzero zvekutadza kwe inductor

1. The mechanical stress inogadzirwa nemagnetic core mukugadzira machining yakakura uye haina kusunungurwa.

2. Pane kusvibiswa mune magineti core kana hollow magineti core material pachayo haisi yunifomu, iyo inokanganisa magineti mamiriro eiyo magineti core uye inokanganisa kupenya kweiyo magineti core.

3. Nekuda kwekutsemuka kwe sintering after sintering.

4. Kana waya yemhangura yakabatana nemhangura yemhangura nekunyudzwa welding, iyo coil inoputirwa neaini yemvura, ichinyungudutsa iyo insulation yewaya enamelled uye ichikonzera pfupi pfupi.

5. Waya yemhangura yakatetepa, izvo zvinoguma nekunyepedzera welding uye kuvhurika kwedunhu kukundikana kana yakabatana nemhangura strip.

Welding mode

Iyo inductance yeyakaderera frequency chigamba simba inductor inowedzera neisingasviki 20% mushure mekuyerera solder.

Demagnetization inoitika nekuti tembiricha ye reflow soldering inodarika tembiricha yeCurie yeyakaderera frequency chigamba inductor zvinhu. Mushure me demagnetization yechigamba inductor, iyo permeability yechigamba inductor zvinhu inodzokera kune yakanyanya uye inductance inowedzera. Iyo general control renji ndeyekuti inductance inowedzera neisingasviki 20% mushure mekunge chigamba inductor inopesana nekupisa kupisa.

Dambudziko rinogona kukonzera solder nderekuti dzimwe nguva dhizaini dhizaini yese inokodzera mune diki batch manual welding (apo chigamba inductor chikasapisa sese, inductance inowedzera zvishoma). Zvisinei, kana pane nhamba huru yemachipisi, inowanikwa kuti kushanda kwemamwe masekete kunoderedzwa. Izvi zvinogona kunge zviri nekuda kwekuwedzera kweiyo inductance yechigamba mushure mekuyerera kwekutengesa, kukanganisa kushanda kwedunhu. Munzvimbo idzo iko kurongeka kwechip inductance kunodiwa zvakanyanya (sekugamuchira chiratidzo uye kufambisa dunhu), kutarisisa kwakanyanya kunofanirwa kubhadharwa kune welding kuramba kwechip inductor.

Kana tembiricha yereflow soldering yasvika, simbi yesimbi inopindirana nerata resimbi kuita eutectic, saka tini haigone kuputirwa zvakananga pamagumo esirivha echigamba inductor. Pane kudaro, magumo esirivheri anotanga akaputirwa nickel kuita insulating layer, yozoiswa tini.

1. Kugumisa oxidation:

Kana chigamba chikabatwa nemagetsi nekupisa kwakanyanya, humidity, makemikari, oxidizing magasi, kana kuchengetwa kwenguva yakareba, iyo simbi Sn pamucheto weinductor wepatch inoiswa oxidized kuSnO2, uye iyo inductor yekupedzisira yechigamba inosviba. Nekuti SnO2 haigadziri eutectic neSn, Ag, Cu, nezvimwe, iyo solderability yechigamba inductance inoderera. Sherufu yehupenyu hwechigamba inductor zvigadzirwa: hafu yegore. Kana iyo inductance magumo echigamba akasvibiswa, senge mafuta zvinhu, zvinonyungudutsa, nezvimwe, zvinokonzeresa kuderera kwe solderability.

2. Nickel coating yakanyanya kutetepa:

Kana iyo nickel plating, iyo nickel layer yakatetepa zvakanyanya kuita basa rekuzviparadzanisa nevamwe. Munguva ye reflow soldering, iyo Sn pamagumo einductor echigamba inobata neAg yayo yekutanga, iyo inokanganisa kunyunguduka kweSn pakupera kweinductor kwechigamba uye solder paste padhi, zvichikonzera chiitiko chekudya. sirivheri uye kudzikira kwekutengesa kwechigamba inductor.

Kutonga nzira: nyudza chigamba inductor mugaba rakanyungudutswa solder kwemasekonzi mashoma woribvisa. Kana makomba akawanikwa pamagumo, kana kunyange muviri we porcelain unoratidzwa, unogona kutongwa kuti pane chiitiko chekudya sirivha.

3. Welding isina kunaka:

Kana iyo chigamba inductor chigadzirwa chine kubhenda deformation, pachave nekukudza mhedzisiro panguva yewelding. Welding isina kunaka, welding yenhema, pad design isina kunaka.

a. Zvose zvigumo zvepadhi zvinofanira kugadzirwa kuti zvidzivirire hukuru hwakasiyana, kana zvisina kudaro nguva yekunyunguduka uye simba rekunyorova remigumo miviri ichave yakasiyana.

b. Kureba kwewelding kuri pamusoro pe 0.3mm (ndiko kuti, kuenzana kureba kwesimbi yekupedzisira kwechigamba inductor uye padhi).

c. Kureba kwepadhi idiki sezvinobvira, kazhinji haapfuuri 0.5mm.

d. Iyo hupamhi hwepadhi pachayo haifanire kunge yakafaranuka, uye hupamhi hwayo hunonzwisisika hahufanire kudarika 0.25mm kana ichienzaniswa nehupamhi hweMLCI.

Kana chigamba inductance ichichinja θ angle nekuda kweiyo isina kuenzana solder pad kana kutsvedza kwesolder paste. Nekuda kwesimba rekunyorovesa rinogadzirwa panguva yekunyunguduka kwewelding pad, ari pamusoro apa matatu mamiriro anogona kuumbwa, ayo ega kuzvigadzirisa anotonga, asi dzimwe nguva kudhonza kunowedzera oblique, kana imwe poindi inodhonzwa, uye chigamba inductor. kudhonzwa padhi, kana kutodhonzwa. Oblique kana kuti yakatwasuka (monument phenomenon). Parizvino, iyo yekuisa muchina ine θ angle offset yekuona yekutarisa inogona kuderedza kuitika kwerudzi urwu rwekutadza.

Kana iyo yakarongerwa ikozvino yeakasarudzwa chip inductor mabheji idiki, kana kana paine yakakura impulse ikozvino mudunhu, ikozvino inopisa uye iyo chip inductor kana magineti bead ichakundikana, zvichikonzera kuvhurika redunhu. Bvisa chigamba inductor kubva pabhodhi redunhu kuti uedze, chigamba inductor chinokundikana, uye dzimwe nguva pane zviratidzo zvekuneta. Kana kuneta kwazvino kukaitika, huwandu hwezvigadzirwa zvakakundikana huchawanda, uye zvigadzirwa zvakakundikana mubatch imwechete zvinozosvika zvinodarika 100%.

Iko kukurumidza kutonhora uye kupisa panguva ye reflow soldering kunokonzera kushushikana kwemukati kwechigamba inductor, izvo zvinotungamirira mukuwedzera kwekuremara kwechikamu chiduku chepatch inductor iyo ine ngozi yakavanzwa yedunhu rakavhurika, zvichiita kuti kuvhurika kwedunhu. chigamba inductor. Bvisa chigamba inductor kubva pabhodhi redunhu kuti uedze, iyo chigamba inductor haina basa. Kana paine welding yakavhurika seti, huwandu hwezvigadzirwa zvakakundikana kazhinji hudiki, uye izvo zvakakundikana zvigadzirwa mubatch imwechete zvinowanzove zvisingasviki 1000 mamakisi.

Magnet simba

Muviri weceramic hauna kusimba zvakakwana uye brittle nekuda kwekutadza kunyura kwechigamba inductor kana zvimwe zvikonzero, kana muviri weporcelain wakakuvadzwa kana chigadzirwa chakanganiswa nechisimba chekunze.

Simba rekunamatira

Kana iyo yekunamatira ye sirivheri yevhavha yekupedzisira yechigamba isina kunaka, kana reflow soldering, inductor yechigamba ichitonhora uye ichipisa, kushushikana kunokonzerwa nekuwedzera kwekupisa uye kutonhora kuderera, uye muviri weporcelain unokanganiswa nemasimba ekunze. , zvinokwanisika kukonzera kupatsanurwa uye kudurura kwekupedzisira kwe inductor uye muviri we porcelain; kana kuti padhi yakakura kwazvo, uye kana reflow soldering, simba rekunyorova rinokonzerwa nekunyunguduka kwepaste uye kupera kwekuita kwakakura kudarika kunamatira kwekupedzisira, zvichikonzera kukanganisa kwekupedzisira.

Iyo chigamba inductor inopisa kana kupisa mbishi, kana kune madiki-akatsemuka mukugadzira maitiro. Iko kukurumidza kutonhora uye kupisa panguva yekuyerera solder kunokonzera kushushikana mukati mechigamba inductor, crystal crack, kana micro-crack kuwedzera, zvichikonzera kukuvara kwemagineti uye zvichingodaro.
