Board assembly with board reinforcing structure, and electronic device with the board assembly

摘要

Disclosed is a board reinforcing structure for reinforcing a circuit board (10) in which an electronic component (12) is mounted on a first surface (10a), the electronic component having an electrode arranged in a rectangular-shaped region on the first surface. The board reinforcing structure includes a reinforcing member (16) bonded to positions corresponding to corner parts of four corners of the rectangular-shaped region on a second surface (10b) provided on a side opposite to the first surface of the circuit board. In the board (16a) reinforcing structure, corresponding one of notches is formed in the reinforcing member at a position corresponding to one of the corner parts of the four corners of the rectangular-shaped region, and at least two apexes of the reinforcing member directed to an outside are formed to shape a contour thereof with the one of the notches.
