As defined in IPC-D-50, PWB refers to a board that has nothing but
  connecting lands etched
  into it.  PCB refers to a board that has active circuitry, capacitors,
  resistors, etc..., etched into
  it. In most conversations and communications such as this, PCB is used
  instead of PWB.

  Subject:  PWB and PCB???





  Is there a difference between a
  PWB - Printed Wiring board and
  PCB - Printed Circuit Board
  in the industry?

  Is it safe to assume (uh-oh) the PWB is the bare board and
  the PCB is the PCB w/components, i.e. a PCB assembly?

  Does anyone out there make a strict division between the two this way?
