Abstract
A multilayer printed circuit board may include traces that are printed on selected layers of the board so that the traces extend to the edge of the corresponding layer. When the layers are assembled together, the ends of the traces may be viewable on a side of the printed circuit board. The traces may be arranged to convey information. For example, trace ends may be readable as one or more binary words, as alphanumeric characters or as a bar code.
Claims18
A multilayer printed circuit board, comprising:
- a first insulating layer and a second insulating layer, each layer having an edge that together form a side of the printed circuit board;
- and
- a plurality of marking traces located between the first and second layers, and wherein each marking trace has an end located at the edges of the layers, and the marking traces are arranged in a pattern so that the ends of the marking traces form at least part of a pattern on the side of the printed circuit board, the pattern on the side of the printed circuit board conveying information about the printed circuit board.
An electronic device, comprising:
- a housing;
- electrical circuit components;
- a multilayer printed circuit board, wherein the electrical circuit components are mounted to the printed circuit board and the printed circuit board is enclosed within the housing, and the printed circuit board including:
- a first insulating layer and a second insulating layer, each layer having an edge that together form a side of the printed circuit board;
- and
- a plurality of marking traces located between the first and second layers, and wherein each marking trace has an end located at the edges of the layers, and the marking traces are arranged in a pattern so that the ends of the marking traces form at least part of a pattern on the side of the printed circuit board, the pattern on the side of the printed circuit board conveying information about the printed circuit board.
