[TriEmbed] PCB Track Width for High Current

[Ron Craig]

I'll let the pros answer, but by my math, a 6.25mm hole would be required
to give you a 20mm wide copper connection.  Since only half the current is
flowing through the via, maybe a 3.2mm hole would be enough. Dunno if
that's practical, though.
