DEFINITION

Classification: 29/846

Manufacturing circuit on or in base:

(under subclass 829) Process of manufacturing a conductive path to, on, or in an insulative base.

(1) Note. A circuit functions only to electrically connect two points, devices, etc., whereas a terminal functions to both electrically and mechanically connect two points, devices, etc.

(2) Note. A circuit may be manufactured by molding, coating, etching, wire forming, etc., or a combination of these steps.
