4 layer PCB
,Im using vias with diameter=
- pad= 0.45mm, for signal track.
Normally beetwen 2 ground plane I use the same vias, randomly positioned in this plane.
Questio is: is better use the same vias for gnd plane, or could be better use bigger vias Es 0.4-0.7mm or more?
The attach photo clarify what I means: 2 vias for GND and 2 vias for UART.
Thanks for your time
