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

A disk device comprising:

• a magnetic disk;
• a magnetic head configured to read and write information from and to the magnetic disk;
• a flexible printed circuit board with an exposure hole, electrically connected to the magnetic head, the flexible printed circuit board including a first layer, a first pad on a surface of the first layer, and a second layer covering the surface, the exposure hole penetrating the second layer to expose the surface and the first pad;
• and
• an electronic component mounted on the flexible printed circuit board and including a case which is provided with a wiring, wherein
• the wiring comprises a bonded part bonded to the first pad through a solder, and a first lead located between the bonded part and the case,
• in a direction along the surface, the first lead is apart from the bonded part in a first direction, the first direction being a direction along the surface,
• in a direction orthogonal to the surface, the first lead is farther away from the surface than the bonded part, and
• an inner surface of the exposure hole is apart from a first end of the first pad, the first end being an end of the first pad in the first direction.

A disk device comprising:

• a magnetic disk;
• a magnetic head configured to read and write information from and to the magnetic disk;
• a flexible printed circuit board comprising a first pad, the flexible printed circuit board being electrically connected to the magnetic head;
• an electronic component mounted on the flexible printed circuit board;
• and
• a first plate having rigidity higher than the flexible printed circuit board and attached to the flexible printed circuit board, wherein
• the electronic component comprises a case and a wiring comprised in the case, the wiring bonded to the first pad through a solder,
• the flexible printed circuit board with a first through hole comprises
• a first surface facing the electronic component with a space, the space that lies between the first surface and the case,
• a second surface opposite the first surface and facing the first plate,
• a first layer having the first surface, and
• a second layer covering the first surface and located apart from the case,
• the first through hole being open to the first surface and the second surface to communicate with the space, and
• the first plate is provided with a second through hole penetrating the first plate to communicate with the first through hole.
