Inductor Chev Tsab Ntawv Thov

Nyob rau hauv Suav teb, muaj ntau cov neeg lag luam hauv kev lag luam thiab cov kev lag luam toroidal inductor. Feem ntau cov khoom lag luam tuaj yeem ua rau muaj hluav taws xob loj inductor dawb kuaj. Yog hais tias koj xav yuav inductor coils koj yuav tsum paub cov inductor coil daim ntawv thov. Tsab ntawv xov xwm no yuav qhia rau koj kom pom tseeb Inductor coil application otes.

Inductive Khoom Tsom Faj Inductor Daim Ntawv Thov Cov Lus Thov

1.Cov xwm txheej mob

Yuav kom tswj tau cov kev cawm dim ntawm Stirnelektrode:

(1) Cov dej kub thiab humidity muaj tsawg dua 40 ° C thiab 70% RH.

(2) Nws raug nquahu kom siv lub thawv ntim khoom siv thooj li 6 lub hlis.

(3) Cov ntaub ntawv ntim yuav tsum tsis txhob muaj cov tshuaj chlorine thiab cov tshuaj lom.

2. Nqa khoom

(1) Cov caws pliav thiab lub tshuab nqus tsev siv tau raug pom zoo kom muab cais tawm ntawm lwm cov khoom.

(2) Thaum sib quag, ntau xim yuav tsum muab coj los ua kom tsis txhob txhuam thiab ua haujlwm tsis zoo.

(3) Lub wafer ceramics electrically inductively handleed kom tsis txhob muaj kev puas tsuaj thiab cov roj ntsha cov tawv nqaij.

3. Tus qauv tsim ntawm Daim Qauv Txawv

Qhov electrode padding ntawm tsim nyog yuav tsum tsim kom ua tau zoo lub tsho kom zoo thiab txo cov khoom tiv thaiv thaum lub sij hawm rov zoo. Cov nram qab no yog ib cov qauv siv tes ua rau cov yawm los yog rov pom cov txheej txheem ntawm qhov ntau thiab tsawg ntawm multilayer ceramic. Qhov tsim ntawm cov qauv no yog raws li nram no:

(1) Lub dav ntawm lub plhaws lub plhaws yog tib yam li qhov dav ntawm kev tivthaiv. Txo mus rau 85% ntawm txoj kev tiv thaiv dav, tab sis nws tsis txawj ntse txo nws ntau dua.

(2) Lub vuam yas overlaps qab ntawm kev tivthaiv los ntawm 0.5 mm.

(3) Rau reflow, lub vuam mat extends tawm ntawm kev tivthaiv los ntawm 0.5 mm; cov yoj yoj yoj yoj tshaj yog 1.0 hli tshaj.

(4) Cheebtsam ncua:

Rau cov tshooj yawg laug, peb yuav tsum muaj kev sib tw txaus kom tiv thaiv tau lub tsho ntawm txhua qhov chaw me me. Cov pob txha tsis tshua tseem ceeb rau kev xav, tiam sis kuj tseem muaj cov kev sib tw txaus los tiv thaiv kev ua haujlwm hnyav.

4. Xa ntawv

Yog tias tsis txhob thermal shocks thaum lub vuam tseem ceeb, yog li yuav tsum tau ua ntej. Qhov kub ntawm qhov preheating yuav tsum tsis pub tshaj 4 ° C / sec, qhov pom zoo tus nqi yog 2 ° C / sec. Txawm hais tias qhov txawv ntawm 80 ° C txog 120 ° C feem ntau, cov kev tshawb fawb tsis ntev los no tau pom tias nws yog qhov ua tau sib txawv ntawm qhov kub thiab txias ntawm cov khoom siv li ntawm 150 ° C rau 1210-txheej txheem nrog lub thickness ntawm tsawg tshaj 1.25 hli. Cov neeg siv yuav tsum paub hais tias thermal shock nce raws li tivthaiv loj lossis kub nce.

5. Kev Nyuaj Siab

Lub qhov fais fab zoo tuaj yeem tau los ntawm immersing lub ntsej muag kawg hauv lub 235 ± 5 ° C 60/40 tin / lead hlau taws rau 2 ± 1 vib nas this.

6. Kev xaiv mob

Txij li thaum lub fwj dej muaj kev cuam tshuam loj heev rau ntawm qhov kev tivthaiv, cov hauv qab no yuav tsum tau paub tseeb ua ntej siv:

(1) Tus nqi flux yuav tsum tsawg dua los yog sib npaug li 0.1% ntawm qhov hnyav ntawm cov tshuaj hawv (sib thooj rau cov tshuaj chlorine). Flux uas muaj cov kua qaub tawv yuav tsum raug zam.

(2) Thaum siv cov thooj sab hauv lub substrate, qhov siv cov flux siv yuav tsum raug tswj kom zoo tshaj plaws.

(3) Thaum siv cov kua dej-soluble flux, tshwj xeeb yuav tsum tau them rau kev tu lub substrate.

7. Vuam

Kev tuaj yeem tos me me rosin fluxes yog txais tos. Siv qhov tsawg kawg nkaus ntawm qhov mob txaus kom ntau li ntau tau nrog kev ua ke zoo uas tuaj yeem tau txais. Cov kaus hniav ntau dhau los ua rau muaj kev ntxhov siab vim qhov sib txawv hauv expansion coefficients ntawm cov kab laug sab, cov txiv ntoo, thiab cov substrate.

8. Welding

(1) Reflow

(2) Kev yoj tes

Kev yoj lub cev yog kab tias feem ntau xav tau cov txheej txheem hnyav vim hais tias muaj qhov kub siab thaum sawv ntsug thaum nyob hauv lub cev yaj ywm, feem ntau 240 ° C. Yoj cov kab xev laminated inductors loj dua 1812, vim qhov kev pheej hmoo ntawm kev puas tsuaj rau qhov inductor vim thermal shock. Yog li ntawd, nws tsis raug txhawb.

(3) Cov hlau hnyav

Kev siv cov hlau nplaum nrog cov kav hlau yaug nrog cov kav hlau yub tsis tau zoo li nws yog los ntawm kev ua kom muaj qhov tsis txaus siab. Yog tias koj yuav tsum tau siv ib cov hlau nplaum, nws yog qhov pom zoo kom them nyiaj rau cov lus hauv qab no.

· Preheat txoj kab thiab tsis kam mus txog 150 ° C.

· Cov taub ntawm cov hlau hnyav hnyav yuav tsum tsis txhob kov cov zwj ntse.

• Siv ib lub fwj fwj yas siv nrog 20 watts thiab ib lub kav hlau ntxeem hlau uas muaj ntsis 1.0 mm.

• Lub taub hau ntawm cov kav hlau muaj qhov siab tshaj plaws ntawm 280 ° C.

· Qhov nruab nrab ntawm cov kav hlau ntawm cov kav hlau yog li 1.0 hli

· Welding lub sij hawm tsawg dua peb feeb.
