Pcblub pauv hloov, tseem hu ua cov ntawv luam tawm Circuit Court transformer, yog tus transformer ua siv cov luam tawm Circuit Co Board Tshuab. Nws yog qhov zoo ib yam li cov tsoos Electromagnetic Transformer, thiab ob qho tib si ua haujlwm raws Faraday txoj cai ntawm indectromagnetic induction. Cov hauv qab no yog cov ncauj lus kom ntxaws ntawm cov ntsiab cai ntawm PCB transformer:
1. Lub ntsiab cai ntawm indectromagnetic induction: tus ua haujlwm ntawm PCB transflicet yog, thaum tus neeg saib xyuas kev hloov pauv yuav tsim tawm hauv tus neeg xyuas pib. Nyob rau hauv lub transformer, qhov hloov pauv sib nqus no yog tsim los ntawm kev ntws ntawm lwm txoj kev hloov tshiab hauv thawj kauj.
2. Chev qauv: PCB hloov feem ntau muaj ob lossis ntau dua coils, uas tau luam tawm ntawm PCB. Lub kauj ruam tseem ceeb (lossis thawj sab) tau txuas nrog cov lus qhia voltage, thaum lub sijhawm theem nrab) txuas nrog lub nra.
3. Lub luag haujlwm ntawm cov tub ntxhais ua haujlwm sib nqus: txhawm rau txhim kho kev ua tau zoo ntawm cov kev hloov pauv, kev sib nqus yog ib txwm muab tso rau ntawm thawj lub coil thiab cov kauj theem nrab. Cov khoom siv ntawm cov hlau nplaum yog feem ntau ferrite lossis lwm cov ntaub ntawv sib nqus, uas tuaj yeem txhim kho lub zog ntawm cov khoom sib nqus thiab txhim kho kev ua haujlwm ntawm lub zog kis.
4. Kev hloov pauv piv txwv: kev hloov pauv ntawm tus hloov pauv tau txiav txim siab los ntawm cov tig sib piv ntawm tus thawj coil thiab cov kauj theem nrab. Yog hais tias tus coil theem theem muaj tsawg dua li cov coil thawj, tus hloov pauv yuav nqis qis dua cov hluav taws xob; Hloov siab, yog tias cov coil theem qub muaj ntau dua cov kauj hauv thawj lub kauj, cov hloov pauv yuav nqis ntaiv nce lub tshuab hluav taws xob.
5. Kev hloov pauv hluavtaws zog: Thaum AC tam sim no hla dhau ntawm tus thawj kauj, nws ua rau muaj kev hloov sib nqus sib nqus. Qhov kev hloov pauv hloov no pauv mus rau theem theem nrab kauj los ntawm kev sib nqus me me, thiab ib qho kev sib nqus ntawm cov hlau nplaum yog tsim nyob rau hauv cov ntsiab lus theem nrab ntawm indectromagnetic induction. Nyob rau hauv txoj kev no, lub zog hloov los ntawm thawj kauj ruam rau cov kauj theem nrab chev.
6. Cov lus teb: PCB transformers tuaj yeem tsim tau los hloov kho kom haum ntau zaus. Hauv kev siv pcb high-zaus, tus qauv ntawm PCB transformers yuav tsum tau txiav txim siab carasitic paus taus thiab parasitic inductance, uas yuav cuam tshuam kev ua haujlwm ntawm tus transformer.
7. Cua sov dissipation teeb meem: Vim yog cov qauv tsim qauv ntawm PCB transformers, tshav kub tsis tuaj yeem ua ib qho teeb meem. Tsim nyog tshav kub dissipation yuav tsum tau txiav txim siab thaum lub sijhawm tsim, xws li siv lub tshuab cua sov lossis nce cov cua sov dissipation cheeb tsam ntawm PCB.
8. Daim ntawv thov: PCB hloov pauv tau siv dav hauv ntau yam khoom siv hluav taws xob, suav nrog qhov loj me, tsim qauv teeb meem, tsim qauv zoo thiab tus nqi zoo.
9. Cov kev txiav txim siab tsim qauv: Thaum tsim qauv PCB, muaj ntau yam khoom siv, cov khoom siv tseem ceeb, thiab yuav txo qis hluav taws xob hluav taws xob cuam tshuam (EMI).
10. Kev tsim khoom txheem: Cov khoom lag luam ntawm PCB transformers cuam tshuam nrog multi-txheej pcb manufacturing thev naus laus zis ntau, suav nrog etching ntawm tooj liab txheej, thiab kev teeb tsa ntawm cov tub ntxhais.
The design and manufacture of PCB transformers is a complex process that requires comprehensive consideration of knowledge from multiple fields such as electromagnetism, thermodynamics, and mechanical engineering. Raws li cov khoom siv hluav taws xob txav mus rau hauv miniaturization thiab siab ua haujlwm, PCB hloov ua si ib qho kev tsim kho hluav taws xob ntau hauv kev tsim hluav taws xob niaj hnub no.
