POWER SUPPLY PATH STRUCTURE OF FLEXIBLE CIRCUIT BOARD

摘要

A power supply path structure is provided for a flexible circuit board and includes a first flexible circuit board that includes at least one first connection pad and a first opposite connection pad and a first power supply path connected between the first connection pad and the first opposite connection pad and a second flexible circuit board that includes at least one second connection pad and a second opposite connection pad and a second power supply path connected between the second connection pad and the second opposite connection pad. The first flexible circuit board is stacked, in a vertical direction, on the second flexible circuit board in such a way that the first power supply path and the second power supply path form a parallel-connected power supply path that serves as a power path or a grounding path for the first flexible circuit board.
