A type of circuit board which has conducting tracks superimposed, or "printed", on one or both sides, and may also contain internal signal layers and power and ground planes. An alternative name, Printed Wire Board (PWB), is commonly used in America.
A polymer-based board containing conductor tracks, onto which are mounted electronic components. The components can either be soldered to the conductor tracks, or interconnected by means of wirebonds (chip and wire) or by solder bumps (flip chip). Syn: printing wiring board.
