Ngaphansi kwesejwayelekile PCB izimo design, lezi zinto ezilandelayo ikakhulukazi ezithinta impedance by PCB yokukhiqiza:

1. Ubukhulu besendlalelo se-dielectric bulingana nenani le-impedance.

2. Okuqhubekayo kwe-dielectric kuyalingana ngokungafani nenani le-impedance.

3. Ubukhulu be-foil yethusi buphikisana ngokulingana nenani le-impedance.

4. Ububanzi bomugqa buya ngokulingana nenani le-impedance.

5. Ubuningi be-inki ne-impedance value ngokulingana ngokulingana.

Ngakho-ke kufanele sinake amaphuzu angenhla lapho silawula impedance.
