Under zvakajairika PCB dhizaini mamiriro, zvinotevera zvinhu zvinonyanya kukanganisa impedance nePCB yekugadzira:

1. Ukobvu hwenzvimbo yedielectric hwakaenzana neiyo impedance kukosha.

2. Dielectric inogara iri inversely yakaenzana kune impedance kukosha.

3. Ukobvu hwemhangura foil hwakapesana zvakaenzana neiyo impedance kukosha.

4. Mutsara upamhi hwakapesana zvakaenzana neiyo impedance kukosha.

5. Ink ukobvu uye impedance kukosha inopesana zvakaenzana.

Saka isu tinofanirwa kuteedzera kune ari pamusoro mapoinzi kana tichidzora impedance.
