Properties:

An electrically insulated item designed primarily to be used for the fabrication of a printed wiring board or printed circuit board for electrical and electronic circuits. It may or may not be laminated or copper clad. For items with metal cladding the electrical conductor paths must be capable of being deposited, etched, or printed in various patterns. Excludes items having printed electronic components, such as capacitors, resistors, and the like. For items processed with electrical conductive paths deposited, etched, or printed in various patterns, see printed wiring board.
