Abstract:
1. A flexible printed circuit board, comprising: a flexible base defining a first end and an opposite second end along a lengthwise direction thereof; a working trace region formed on the flexible base, the working trace region being formed by a plurality of working traces, the working trace region defining a first end nearest the first end of the flexible base and an opposite second end nearest the second end of the flexible base; and at least one reinforcement trace formed on the flexible base, the reinforcement trace being disposed at a periphery of the working trace region; wherein the at least one reinforcement trace generally extends along the lengthwise direction of the flexible base and defines a first end nearest the first end of the flexible base and an opposite second end nearest the second end of the flexible base, the first end of the at least one reinforcement trace is nearer the first end of the flexible base than is the first end of the working trace region, and the second end of the at least one reinforcement trace is nearer the second end of the flexible base than is the second end of the working trace region.
