摘要: According to one embodiment, a disk device includes a first FPC and second FPCs. The first FPC includes a first insulating layer, a second insulating layer covering the first insulating layer, and a first conductive layer between the first insulating layer and the second insulating layer. The first conductive layer is provided with first terminals. The second insulating layer is provided with holes through which the first terminals are exposed. The second FPC includes a first face facing the second insulating layer, a second face opposite the first face, and second terminals on the first face. The second terminals are joined to the first terminals with a conductive bonding material. At least one second face includes a first area being lower in lightness than a part of the first FPC, the part where the first conductive layer is covered by the second insulating layer.

摘要: 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.

摘要: According to one embodiment, a storage includes a flexible printed circuit board and an electronic component. The flexible printed circuit board includes a first insulating layer, a first conductive layer on a first surface of the first insulating layer, and a second conductive layer on a second surface of the first insulating layer. The second surface is opposite the first surface. The first conductive layer is provided with a land. The second conductive layer covers the land via the first insulating layer in a first direction in which the first surface faces. The electronic component includes a pin joined to the land.
