ABSTRACT:
A circuit board with identifiable information and a method for fabricating the same are proposed. At least one insulating layer within the circuit board has a non-circuit area free of a circuit layout. A plurality of openings are formed in the non-circuit area of the insulating layer. A patterned circuit layer is formed on the insulating layer. Metal identifiable information is disposed in the openings of the non-circuit area. By this arrangement, a product status of the circuit board can be traced and identified via the metal patterned information.
