Default Re: When did PCB tracks become 'traces'?

Kind of. 'Plated through holes' describe any hole in the PCB which contains plating between the outer layers. A plated through hole may contain a component leg, or just be there for an electrical connection, or may have only a mechanical function, like a mounting hole.

A 'via', on the other hand, is quite specifically for connecting layers together and no other purpose - it won't have a component leg or anything else in it.

All vias are plated through holes, but not all plated through holes are vias.

The distinction is clear and unambiguous, at least in professional use.
