    Pawv pem

    PCB pawg ua pawg yog qhov tseem ceeb hauv kev txiav txim siab EMC kev ua haujlwm ntawm ib qho khoom. Qhov teem kom zoo tuaj yeem ua kom muaj txiaj ntsig zoo nyob rau hauv kev txo hluav taws xob los ntawm lub loo rau ntawm PCB, nrog rau cov txuas txuas txuas nrog hauv pawg thawj coj.

    Plaub yam tseem ceeb nrog rau kev txiav txim txog pawg ua pawg:

    1. Tus naj npawb ntawm txheej,

    2. Tus lej thiab hom dav hlau (fais fab thiab / lossis hauv av) siv,

    3. Kev txiav txim lossis ua ntu zus ntawm txheej txheej, thiab

    4.Qhov sib nrug ntawm cov khaubncaws sab nraud povtseg.

     

    Feem ntau tsis xav txog ntau npaum li cas tsuas yog muab cov naj npawb ntawm cov khaubncaws sab nraud povtseg. Nyob rau hauv ntau ntawm lwm yam peb yam tseem ceeb sib npaug. Hauv kev txiav txim siab tus naj npawb ntawm cov khaubncaws sab nraud povtseg, cov hauv qab no yuav tsum raug xam tias:

    1. Tus naj npawb ntawm cov cim yuav tsum lem thiab nqi,

    2. Zaus

    3. Cov khoom puas yuav tau ua raws li Chav Kawm A lossis Class B kev tshaj tawm?

    Feem ntau tsuas yog thawj qhov khoom raug txiav txim siab. Hauv kev muaj tiag txhua yam khoom yog qhov tseem ceeb thiab yuav tsum tau txiav txim siab sib npaug. Yog tias qhov kev tsim kho zoo tshaj plaws yuav tsum tau ua tiav ntawm qhov tsawg kawg nkaus ntawm lub sijhawm thiab tus nqi qis kawg, yam khoom kawg tuaj yeem yog qhov tseem ceeb tshaj plaws thiab yuav tsum tsis raug zam.

    Cov lus saum toj saud yuav tsum tsis txhob txhais hais tias koj tsis tuaj yeem ua qhov zoo EMC tsim ntawm plaub- lossis rau-txheej txiag, vim tias koj tuaj yeem ua tau. Nws tsuas yog qhia tias txhua lub hom phiaj tsis tuaj yeem ua tiav ib txhij thiab qee qhov kev txiav txim siab yuav tsim nyog. Txij li txhua qhov xav tau EMC cov hom phiaj tuaj yeem ntsib nrog yim-txheej pawg thawj coj, tsis muaj laj thawj rau kev siv ntau tshaj li yim txheej dua li kom haum cov teeb liab hla kev ntxiv.

    Tus txheem pas dej da dej tuab rau multilayer PCBs yog 1.55 hli. Nov yog qee qhov piv txwv ntawm multilayer PCB pawg teeb.

    Hlau Tub ntxhais PCB

    Hlau Hlau Daim Ntawv Luam Tseg Circuit Board (MCPCB), lossis thermal PCB, yog ib hom PCB uas muaj cov khoom siv hlau ua nws lub hauv paus rau lub tshav kub kis ntawm pawg thawj coj. Lub hom phiaj ntawm qhov tseem ceeb ntawm ib qho MCPCB yog kev hloov pauv kub kom deb ntawm cov pawg tseem ceeb thiab mus rau qhov chaw tseem ceeb xws li cov hlau heatsink thaub qab lossis cov tub ntxhais hlau. Lub hauv paus hlau hauv MCPCB yog siv los ua lwm txoj hauv FR4 lossis CEM3 cov laug cam.

     

    Cov Khoom Siv Hlau Hlau PCB thiab Thickness

    Cov tub ntxhais hlau ntawm cov thermal PCB tuaj yeem yog aluminium (aluminium core PCB), tooj liab (tooj liab tseem ceeb PCB lossis hnyav tooj liab PCB) lossis sib xyaw ntawm cov txhuas tshwj xeeb. Lub ntsiab lus feem ntau yog txhuas tus tub ntxhais kawm PCB.

    Lub thickness ntawm hlau kauj hauv PCB puag paib yog feem ntau 30 mil - 125 mil, tab sis tuab thiab nyias daim hlau kuj muaj peev xwm.

    MCPCB tooj liab ntawv ci tuab tuaj yeem yog 1 - 10 oz.

     

    Qhov zoo ntawm MCPCB

    MCPCBs tuaj yeem siv kom zoo rau lawv lub peev xwm los sib sau ua cov dielectric polymer txheej nrog lub siab ua kom zoo rau kev ua haujlwm qis dua thermal.

    Hlau tub ntxhais PCBs hloov lub tshav kub 8 txog 9 zaug sai dua li FR4 PCBs. MCPCB laminates dissipate tshav kub, ua kom muaj cov cua sov ua rau muaj cua sov txias dua uas ua rau muaj kev ua tau zoo thiab lub neej.
