Hi Steve,

I grew up with the term PCB, and PWB always seemed a bit foreign to me.

I could be off the mark so someone please correct me if I'm wrong, but my
understanding is that PWB and PCB are synonymous in what they represent, and
neither of the terms refer to wire-wrapping which is a different process.

Perhaps PWB is an older term before PCB became widely used?
But, maybe not, see below.
Does someone know the history behind this?

If the below reason is true for using the term PWB is true, this acronym
name game is pretty interesting:

"In Japan, the printed wiring board used to be called a "Printed Circuit
Board." Nowadays in Japan the name "Printed Circuit Board" is not used
because the initials of "Printed Circuit Board" are "PCB." PCB also stands
for "Polychlorinated Biphenyls (PCBs)," which is a poison. So in Japan, we
refer to the boards as "Printed Wiring Boards." In other countries, they are
still referred to as "Printed Circuit Boards," or PCBs."


Best regards,

Ken Pergola
