A disk device includes a magnetic disk, a magnetic head, a flexible printed circuit board, an electronic component, and a wall. The flexible printed circuit board is electrically connected to the magnetic head. The electronic component is mounted on the flexible printed circuit board. The wall has rigidity higher than the flexible printed circuit board and is attached to the flexible printed circuit board. The flexible printed circuit board with a first through hole includes a first surface facing the electronic component with a gap, and a second surface opposite the first surface and facing the wall, the first through hole being open to the first surface and the second surface to communicate with the gap. The wall is provided with a second through hole penetrating the wall to communicate with the first through hole.

Disk device having an electronic component on a flexible printed circuit board

According to an embodiment, an electronic device includes a substrate and an electronic component. The substrate includes a first surface facing a first direction and to which a first hole and a second hole are open. The electronic component includes a base, a first protrusion in the first hole, and a second protrusion in the second hole. The first protrusion and the second protrusion protrude from the base. The first end of the first protrusion is more apart from the first surface than the second end of the second protrusion. The first protrusion and the second protrusion have a first inclined surface and a second inclined surface extending obliquely with respect to the first direction. In a third direction orthogonal to the first direction the first inclined surface is longer in length than the second inclined surface.
