I lalo o le masani ai PCB mamanu tuutuuga, o mea taua mulimuli ane aafia ai le impedance e PCB gaosiga:

1. O le mafiafia o le dielectric vaega e faʻatusatusa i le impedance aoga.

2. Dielectric faifai pea e fesuiaʻi faʻatusatusa i faʻafitauli aoga.

3. O le mafiafia o apamemea foil e faʻatusatusa faʻatusatusa i le faʻafitauli aoga.

4. O le lautele lautele e faʻafeagai faʻatusatusa i le faʻafitauli aoga.

5. Vaitusi mafiafia ma impedance aoga faʻafetaui faʻatusatusa.

Ma e tatau ona tatou uai atu i luga o manatu pe a faʻatonutonu impedance.
