Abstract

A wired circuit board assembly sheet has a plurality of wired circuit boards, distinguishing marks for distinguishing defectiveness of the wired circuit boards, and a supporting sheet for supporting the plurality of wired circuit boards and the distinguishing marks. Each of the distinguishing marks has an indication portion for indicating a specified one of the wired circuit boards.

Claims

1. A wired circuit board assembly sheet comprising:

a plurality of wired circuit boards;

defect-distinguishing marks which distinguish defectiveness of the wired circuit boards; and

a supporting sheet for supporting the plurality of wired circuit boards and the defect-distinguishing marks,

wherein each of the defect-distinguishing marks comprises an indication portion for indicating a specified wired circuit board,

wherein the defect-distinguishing marks are not attached to the wired circuit boards;

wherein each of the defect-distinguishing marks is provided on the supporting sheet in a spaced-apart relation from the specified wired circuit board corresponding to said each defect-distinguishing mark, and the indication portion indicates the specified wired circuit board from external of the specified wired circuit board; and

wherein the indication portion has a shape tapered toward an indication direction indicating the specified wired circuit board, so as to distinctly represent a correspondence between a particular defect-distinguishing mark and the specified wired circuit board by directing the indication direction of the indication portion toward the specified wired circuit board to thereby identify a defective wired circuit board from among the plurality of wired circuit boards supported on the supporting sheet.

2. The wired circuit board assembly sheet according to claim 1, wherein each of the defect-distinguishing marks is formed in a non-point-symmetrical shape.

3. The wired circuit board assembly sheet according to claim 1, wherein each of the defect-distinguishing marks has a generally polygonal shape having an odd number of angles.

4. The wired circuit board assembly sheet according to claim 1, wherein the defect-distinguishing marks are arranged in mutually adjacent relation;

and

wherein the indication portions of the defect-distinguishing marks are arranged in adjacent relation having respective indication directions different from each other.
