As I know, there exist limits on maximum current, a pcb via can tolerate before it melts before the via's temperature rises unacceptably high above ambient (say 10-100 C above ambient depending on application).
What are standard values or rules of thumb for the maximum current (or current density) through a pcb via?
PS: the question is about DC, but any additional considerations (if any) for a high frequency current are welcome as well.
