Iinkcukacha zeMveliso

Malunga ne-Impedans

I-Impedans yindibaniselwano ye-capacitance kunye ne-inductance ukuvimba isiphaluka kwisignali ephezulu.I-Impedance luhlobo lweempawu ze-AC, okuthetha ukuba inxulumene rhoqo kwaye isetyenziselwa ukuchaza iimpawu eziphezulu ze-PCB.

Izinto ezichaphazela i-Impedans

DK (R):igqitywe ngemathiriyeli ekrwada (i-PCB imathiriyeli, iphepha elinyangekileyo)

Ukutyeba komgca (T):igqitywe yimathiriyeli ekrwada kunye nekhono lenkqubo.

Ububanzi bomgca (W):igqitywe luyilo loqobo lomthengi kunye nekhono lenkqubo.

Ubukhulu obuphakathi (H):igqitywe luyilo loqobo lomthengi, isakhono senkqubo kunye nemathiriyeli ekrwada.

Ngoko ke, kuyilo lwe-PCB, kufuneka silawule ukungasebenzi kweengcingo ebhodini, ukuze siphephe ukubonakaliswa komqondiso kunye nolunye uphazamiseko lwe-electromagnetic kunye neengxaki zengqibelelo yomqondiso kangangoko kunokwenzeka, kwaye siqinisekise ukuzinza kokusetyenziswa kwe-PCB. .
