    Stack kumusoro

    Pcb yekukwira-kumusoro chinhu chakakosha mukumisikidza EMC mashandiro echigadzirwa. Iyo yakanaka stack-up inogona kushanda zvakanyanya mukudzora radiation kubva kune zvishwe paPCB, pamwe netambo dzakabatanidzwa kubhodhi.

    Zvinhu zvina zvakakosha zvine chekuita nebhodhi rekusimudzira-kumusoro kufunga:

    1. Kuwanda kwezvikamu,

    2. Huwandu nemhando dzendege (simba uye / kana pasi) dzakashandiswa,

    3. Kurongeka kana kuteedzana kwezvikamu, uye

    4. Kusiyanisa pakati pezvikamu.

     

    Kazhinji hazvifungi zvakanyanya zvinopihwa kunze kwekuwanda kwenhamba. Muzviitiko zvakawanda zvimwe zvinhu zvitatu zvakakosha zvakaenzana. Mukufunga nezve huwandu hwematanda, zvinotevera zvinofanirwa kutariswa.

    1. Huwandu hwezviratidzo zvekuendeswa uye mutengo,

    2. Kakawanda

    3.Chigadzirwa chichafanirwa kusangana neClass A kana Kirasi B zvinodiwa here?

    Kazhinji chete chinhu chekutanga chinotariswa. Muchokwadi zvinhu zvese zvakakosha zvakakosha uye zvinofanirwa kutariswa zvakaenzana. Kana dhizaini yakawandisa ichizadzikiswa muhuwandu hushoma hwenguva uye nemutengo wakaderera, chinhu chekupedzisira chinogona kunyanya kukosha uye hachifanirwe kufuratirwa.

    Ndima iri pamusoro haifanire kutorwa kureva kuti haugone kuita yakanaka EMC dhizaini pane ina- kana matanhatu-masenduru bhodhi, nekuti unogona. Izvo zvinongoratidzira chete kuti zvese zvinangwa hazvigone kuzadzikiswa panguva imwe chete uye kumwe kuwirirana kuchazodiwa. Sezvo zvese zvinangwa zveEMC zvichikwanisika kusangana neyakaenzana masere bhodhi, hapana chikonzero chekushandisa anodarika masere maseru kunze kwekutora mamwe maratidziro erondedzero.

    Iyo yakajairika yekudyara ukobvu ye multilayer PCBs iri 1.55mm. Heano mimwe mienzaniso ye multilayer pcb yakaiswa kumusoro.

    Simbi Core Pcb

    A Metal Core Yakadhindwa Circuit Board (MCPCB), kana inodziya pcb, rudzi rwePCB iyo ine simbi yekushandisa sehwaro hwayo hwekuparadzira chikamu chebhodhi. Chinangwa cheiyo yakakosha yeMCPCB ndeyekutungamira kupisa kubva kure kwakakosha bhodhi zvinhu uye kunzvimbo dzisinganyanye kukosha senge simbi heatsink inotsigira kana simbi simbi. Simbi dzesimbi mu MCPCB dzinoshandiswa seimwe nzira kune FR4 kana CEM3 mabhodhi.

     

    Metal Core pcb Zvekushandisa uye Ukobvu

    Iyo simbi musimboti weiyo inodziya pcb inogona kuve aluminium (aluminium yakakosha pcb), mhangura (mhangura musimboti pcb kana inorema mhangura pcb) kana musanganiswa weakakosha alloys. Inowanzozivikanwa ndeyealuminium pcb pcb.

    Ukobvu hwesimbi cores muPCB base mahwendefa anowanzoita 30 mil - 125 mil, asi mukobvu uye mutete mahwendefa zvinogoneka.

    MCPCB mhangura foil ukobvu inogona 1 - 10 oz.

     

    Zvakanakira MCPCB

    MaMCPCB anogona kuve anobatsira kushandisa kugona kwavo kubatanidza dielectric polymer nhepfenyuro ine yakanyanya kudziya inoitisa kune yakaderera kupisa kupisa.

    Simbi simbi maPCB anotamisa kupisa ka8 kusvika ku9 nekukurumidza kupfuura FR4 PCBs. MCPCB laminates inodzinga kupisa, ichichengeta kupisa kunogadzira zvinhu zvinononoka izvo zvinoguma nekuwedzera kwekuita uye hupenyu.
