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;

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, wherein

each of the distinguishing marks comprises an indication portion for indicating a specified wired circuit boards.

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

3. A wired circuit board assembly sheet according to claim 1, wherein the indication portion has a shape tapered toward an indication direction indicating the specified wired circuit board.

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

5. A wired circuit board assembly sheet according to claim 1, wherein

the distinguishing marks are arranged in mutually adjacent relation and

the indication portions of the distinguishing marks arranged in adjacent relation have respective indication directions different from each other.

6. A wired circuit board assembly sheet according to claim 1, wherein

the supporting sheet has openings formed in the portions where the distinguishing marks are provided and

each of the distinguishing marks comprises:

a removal portion provided in the opening for indicating whether the corresponding wired circuit board is defective or non-defective; and

a joint portion made of a resin for jointing the removal portion to the supporting sheet.
