I noticed that the IPC site refers to circuit boards as "PWB"s (Printed Wiring Boards) rather than "PCB"s (Printed Circuit Boards) because of the potential of confusing circuit boards with the chemical contamination in the Hudson River.
An example of this misunderstanding was an event I witnessed somewhere in Colorado (I think) many years ago. There was a minor acid spill on the plating line and someone decided that it would be a good idea to have some paramedics standing by just in case someone got an acid burn during the cleanup. So he called whatever the precursor to 911 was and said something to the effect that 'there had been a spill at the PCB facility,' and every piece of emergency equipment within 50 miles showed up along with the nightly news team.
What should have been an hour job of pumping the contaminaged acid into barrels turned into a two day public relations nightmare.
Just another bit of PCB trivia.
