4 Layer FR4 OSP Impedance Control PCB
Characteristic Impedance Control PCB
The Impedans khalidwe la kondakitala pa PCB ndi index yofunika ya kamangidwe dera, makamaka mu PCB mapangidwe mkulu pafupipafupi dera, tiyenera kuganizira ngati khalidwe impedance kondakitala n'zogwirizana ndi khalidwe impedance chofunika ndi chipangizo kapena chizindikiro.
Kufanana kwa PCB Impedans
Mu PCB, ngati pali kufalikira kwa ma siginecha, akuyembekezeka kukhala kuchokera kumapeto kwa kutumizira mphamvu, ngati kutayika kwa mphamvu pang'ono, kumatha kufalikira mpaka kumapeto, ndipo kumapeto kolandirira kudzakhazikika kwathunthu. popanda kusinkhasinkha kulikonse.Kuti mukwaniritse izi, cholepheretsa pamzerecho chiyenera kukhala chofanana ndi cholepheretsa chomwe chili mkati mwakumapeto kwake kuti chikhale chotchedwa impedance matching.Kufananiza kwa Impedans ndi chimodzi mwazinthu zopangira popanga ma PCB othamanga kwambiri.Mtengo wa impedance umagwirizana kwathunthu ndi njira yolowera.
Mwachitsanzo, kaya mukuyenda pamtunda (Microstrip) kapena mkati (Stripline/Double Stripline), mtunda kuchokera pagawo lamphamvu kapena wosanjikiza, m'lifupi mwa njira, zinthu za PCB, ndi zina zotero, zonse zimakhudza mtengo wa impedance wa njira.Ndiko kunena kuti, mtengo wa impedance ukhoza kudziwidwa pambuyo pa waya, ndipo mawonekedwe opangidwa ndi opanga PCB osiyanasiyana amasiyananso pang'ono.Nthawi zambiri, pulogalamu yoyeserera siyitha kuyika mawaya ena oletsa kuyimitsa chifukwa cha kuchepa kwa mtundu wa mzere kapena masamu omwe amagwiritsidwa ntchito.
Pakadali pano, ma Temninators ena okha ndi omwe angasungidwe pazithunzi zamakonzedwe, monga kukana kwa mndandanda, kuti muchepetse kulephera kwa waya.Yankho lenileni la vutoli ndikuyesa kupewa kupezeka kwa kuyimitsidwa kwa impedance mukamayimba.
