DEFINITION

Classification: 174/250

Preformed panel circuit arrangement (e.g., printed circuit):

(under subclass 68) Subject matter wherein a cable or conductor is formed on or attached to a panel or sheet-like insulating body so as to form a unitary structure.

(1) Note. The conductor or cable may be made by coating a panel or sheet with conductive material, or by impregnating selected layers of the surface of an insulating body with conductive material, or by attaching preformed conductors to the surface of an insulating-body as by adhesives, etc. Note the reference to Class 428, Stock Material or Miscellaneous Articles, below.

(2) Note. Included in this subclass are such "printed circuit" assemblies as include "branched" circuits (indented subclasses 71+), such assemblies as include joints between the ends of the cables or conductors (subclasses 84+), as well as other "printed circuit" structures properly classified in subclass 68 or one of the indented subclasses.

(3) Note. This subclass and those indented thereunder include printed circuit boards having one or more electrical devices of the same type. Search Class 361, subclasses 397+ for printed circuit boards having plural, diverse electrical devices.
