Via Current Capacity

[JohnsonMiller]

Hi Guys,

How we can calculate via's current capacity?
For example, with 5A how many via and which size is needed?

We use Saturn PCB toolkit, calculate the maximum current for our standard VIA and then divide the maximum current by the current through one VIA. For example, if our VIA maximum current is 1A and we would need to deliver 5A, we place at least 5 VIAs.
