Mayelana ne-Impedance

I-Impedance iyinhlanganisela ye-capacitance kanye ne-inductance ukuze uvimbele umjikelezo kusignali yefrikhwensi ephezulu.I-Impedance iwuhlobo lwesici se-AC, okusho ukuthi ihlobene nemvamisa futhi isetshenziselwa ukuchaza izici eziphakeme zemvamisa ye-PCB.

Izinto Ezithinta Impedance

I-DK (R):kunqunywa ngezinto ezingavuthiwe (i-PCB impahla, ishidi eliphulukisiwe)

Ubukhulu Bomugqa (T):kunqunywa ngezinto ezingavuthiwe kanye nekhono lokucubungula.

Ububanzi Bomugqa (W):kunqunywa umklamo wangempela wekhasimende kanye nekhono lokucubungula.

Ubukhulu obumaphakathi (H):kunqunywa idizayini yasekuqaleni yekhasimende, amandla okucubungula kanye nezinto zokusetshenziswa.

Ngakho-ke, ekwakhiweni kwe-PCB, kufanele silawule ukuthintana kwezintambo ebhodini, ukuze sigweme ukubonakaliswa kwesignali nokunye ukuphazamiseka kukamagnetic kanye nezinkinga zobuqotho besignali ngangokunokwenzeka, futhi siqinisekise ukuzinza kokusetshenziswa kwangempela kwe-PCB. .
