Muaj nuj nqi thiab tsis kam tshuaj xyuas ntawm Inductance Chev | TAU TXAIS

Ua lub luag hauj lwm thaj inductor coil ua si hauv Circuit Court? Puas yog cov yam ntxwv thiab cov yam ntxwv ntawm thaj inductor zoo ib yam? Niaj hnub no, cia peb kawm txog nws.

Kev ua haujlwm ntawm Hollow Inductance Coil

Ua hauj lwm hauv paus ntsiab lus ntawm hlau core inductor kauj:

Cov inductance kauj yog qhov piv ntawm cov hlau nplaum sib nqus hauv cov hlau mus rau qhov tam sim no uas ua rau cov dej hloov pauv sab hauv thiab ib puag ncig ntawm cov hlau thaum AC tam sim no dhau los ntawm cov hlau.

Raws li DC tam sim no dhau los ntawm inductor, tsuas muaj ib txoj kab sib nqus ruaj khov nyob ib puag ncig nws, uas tsis hloov nrog lub sijhawm. Tab sis thaum alternating tam sim no dhau los ntawm lub kauj, nws yog ib puag ncig los ntawm cov kab sib nqus ntawm lub zog uas hloov lub sijhawm. Raws li kev soj ntsuam ntawm txoj cai electromagnetic induction txoj cai, hloov magnetic kab ntawm quab yuam yuav tsim induced muaj peev xwm ntawm ob qho kawg ntawm lub kauj, uas yog sib npaug rau "tshiab fais fab mov". Thaum ib lub voj kaw raug tsim, lub peev xwm induced tsim ib qho induced tam sim no.

Lenz txoj cai paub tias tag nrho cov kab hluav taws xob sib nqus uas tsim los ntawm induced tam sim no yuav tsum raug tiv thaiv los ntawm kev hloov cov kab hlau nplaum qub kom deb li deb tau. Vim hais tias thawj qhov kev hloov pauv ntawm cov kab sib nqus quab yuam los ntawm kev hloov pauv ntawm cov khoom siv hluav taws xob sab nraud AC, lub hom phiaj hais lus, inductor coil muaj cov yam ntxwv ntawm kev tiv thaiv kev hloov pauv tam sim no hauv AC Circuit Court. Inductance coil zoo ib yam li inertia hauv mechanics, uas yog hu ua "self-inductance" hauv hluav taws xob. Feem ntau, sparks tshwm sim nyob rau lub sijhawm thaum lub riam hloov yog qhib lossis qhib. Qhov no yog tshwm sim los ntawm lub siab induction muaj peev xwm tsim los ntawm tus kheej-induction phenomenon.

Vulcanization mechanism ntawm thaj ua haujlwm

Qhov saum npoo ntawm electrode yog nyiaj electrode, qhov nruab nrab electrode yog npib tsib xee txheej, sab nraud electrode yog tin txheej, cov khoom siv electrode yog hlau conductor, cov txheej txheem tiv thaiv thib ob yog cov hlau tsis yog xim hlau, thiab cov txheej txheem hluav taws xob hauv thaj tsam thaj tsam yog nyias nyias los yog tsis tsim ib txheej conductive. tshwj xeeb, ciam teb ntawm kev tshuaj ntsuam luam ntawv thib ob txheej tiv thaiv tsis xwm yeem, thiab cov substrate / nws yog qhov tsis muaj zog ntawm kev tiv thaiv theem nrab thiab cov txheej txheem electrode. Cov roj sulfur corrosion permeates rau saum npoo ntawm cov electrode los ntawm cov txheej txheem ntawm cov hluav taws xob tiv thaiv thib ob thiab cov ciam teb, thiab ua ke nrog cov nyiaj sulfide ntawm cov electrode nto los tsim cov Ag2S. Qhov qis conductivity ua rau cov resistor poob nws cov peev xwm conductive thiab ua tsis tiav.

Txhawm rau kom tsis txhob vulcanization tsis kam, txoj hauv kev zoo tshaj plaws yog siv los tiv thaiv vulcanization. Los ntawm kev nthuav dav qhov tsim loj ntawm cov txheej txheem tiv thaiv theem nrab thiab npog cov electrode hauv qab nrog cov kev tiv thaiv theem nrab mus rau qee qhov loj, Ni txheej thiab Sn txheej yooj yim los npog cov txheej txheem tiv thaiv theem nrab thaum electroplating. Qhov no tsis txhob cuam tshuam ncaj qha ntawm ntug ntawm qhov tsis muaj zog thib ob tiv thaiv txheej rau huab cua ib puag ncig thiab txhim kho cov vulcanization tsis kam ntawm cov khoom.

Lub tswv yim tsim yog los ntawm qhov pom ntawm kev ntim khoom thiab kev pabcuam. Tus tsim los tiv thaiv vulcanization siv carbon-raws li conductive resin nplaum los npog cov electrode nto thiab txuas mus rau theem ob tiv thaiv txheej. Lwm qhov kev tsim los tiv thaiv vulcanization yog los ntawm qhov pom ntawm cov ntaub ntawv, xws li nce cov ntsiab lus ntawm palladium nyob rau hauv qhov chaw electrode Ag / Pd slurry thiab nce cov ntsiab lus ntawm palladium (feem ntau) ntawm 0.5% mus rau ntau tshaj 10%. Vim tias qhov nce ntawm palladium cov ntsiab lus hauv slurry, kev ruaj ntseg ntawm palladium txhim kho lub peev xwm ntawm kev tiv thaiv rau vulcanization. Kev sim qhia tias txoj kev no muaj txiaj ntsig zoo.

Feem ntau hais lus, muaj ob lub tswv yim rau kev tiv thaiv vulcanization tsim, ib qho yog los ntawm qhov pom ntawm encapsulation, lwm qhov yog los ntawm qhov pom ntawm cov ntaub ntawv. Hais txog kev hais lus, hais txog cov khoom siv, nws yog qhov zoo dua los xyuas kom meej tias qhov tsis kam yog vulcanized. Lub PCB pawg thawj coj saib yog coated nrog peb anti-lacquers thiab ib tug tiv thaiv zaj duab xis yog ntxiv rau cais cov huab cua thiab tiv thaiv kuj vulcanization. Lag luam wholesale thaj resistor.

Piv nrog rau cov khoom lag luam zoo tib yam, cov tshuaj tiv thaiv vulcanization yog luam tawm nrog ib txheej ntawm thermal conductive polyurethane filling adhesive, uas plays lub luag haujlwm tiv thaiv.

Lub hwj huam mov ntawm lub kaw lus kaw tag nrho cov kua nplaum puv module txais cov qauv rau tag nrho rau sab. Cov qauv no yuav tsum tau sim nyob rau hauv kev xyaum vim hais tias lub zog module nyob ib ncig ntawm nws cov pins tawm, uas yog, tus pins, yog tsis tiag tiag muab tua. Lwm qhov kev daws teeb meem yog siv qhov tseeb airtight tsim, qhov twg lub hwj chim mov ntawm lub module yog ntim nrog nitrogen los yog argon thiab tsuas yog siv nyob rau hauv cov tub rog los yog aerospace khoom. Vim tias silica gel tuaj yeem adsorb sulfides, lwm txoj hauv kev yog tso tawm cov silica gel thiab txais cov qauv qhib. Cov qauv qhib yuav tsum tau txiav txim siab los ntawm cov yam ntxwv ntawm kev txhim kho lub zog hloov hluav taws xob, kev faib hluav taws xob tsis sib xws thiab yuam kom cov cua sov dissipation. Tam sim no, txawm hais tias cov qauv qhib module fais fab mov yog vulcanized, qhov kev pheej hmoo ntawm vulcanization ntawm lub hwj huam mov tau txo qis heev piv nrog cov modules siv cov silica gel puv. Ceramic substrate fais fab module kuaj cov ceramic substrate thiab luam tawm qhov kev tawm tsam ncaj qha rau ntawm ceramic substrate. Ceramic substrate muaj thermal conductivity zoo. Txawm li cas los xij, ceramic substrate yuav tsum tau coated nrog peb cov xim los tiv thaiv cov nyiaj los ntawm kev txav mus los ntawm qhov kub thiab txias, cov av noo thiab hluav taws xob hluav taws xob, kom tsis txhob muaj luv luv ntawm cov kab. IC pob fais fab mov txais IC pob fais fab mov. Vim lub IC pob fais fab mov thiab IC nti, zoo sealing, tuab diaphragm tsis kam ntawm lub zog sab hauv kev sib cuag tuaj yeem cais cov roj sulfur sab nraud.

Cov ntsiab lus saum toj no feem ntau txheeb xyuas qhov ua haujlwm ntawm cov nti inductor kauj thiab qhov ua haujlwm vulcanization mechanism. Los ntawm kev qhia txog GETWELL thev naus laus zis, Kuv ntseeg tias koj yuav muaj kev nkag siab ntau dua ntawm cov nti inductor. Yog tias koj xav paub ntau ntxiv txog cov chip inductor, thov koj xav tiv tauj peb.
