Be careful when you state this definition as a fact. The two terms PWB and PCB have been used interchangeably in this industry to mean the bare printed wiring board. Although, the IPC-T-50 defines a printed circuit board (PCB) as a printed wiring board (PWB) with components mounted on it, that may not be the way it is used. Old habits have a hard way of dying.
