Patent ID: 8362360

Claim:
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 each of the defect-distinguishing marks has a convex shape when viewed in plan view, such that the indication portion extends 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.
