Flexure of suspension for disk drive and suspension for disk drive, the flexure having an area with reduced thickness where an electronic component is mounted
A flexure of a suspension for a disk drive includes a metal base and a wiring portion provided along the metal base and including a base insulation layer, a conductor layer overlaid on the base insulation layer, and a cover insulation layer overlaid on the conductor layer. The flexure includes a first area on which an electronic component is mounted and a second area aligned alongside the first area, and the first area includes a thin-walled portion which overlaps the electronic component and having a thickness less than a thickness of the second area.
1 . A flexure of a suspension for a disk drive, comprising a metal base and a wiring portion provided along the metal base and including a base insulation layer, a conductor layer overlaid on the base insulation layer, and a cover insulation layer overlaid on the conductor layer, the flexure comprising:
a first area on which an electronic component is mounted and a second area aligned alongside the first area,
wherein:
the first area includes a thin-walled portion which overlaps the electronic component and has a thickness less than a thickness of the second area,
the conductor layer is provided in each of the first and second areas,
a thickness of the conductor layer in the thin-walled portion is less than a thickness of the conductor layer in the second area,
the metal base is provided in each of the first and second areas, and
a thickness of the metal base in the thin-walled portion is less than a thickness of the metal base in the second area.
2 . The flexure of claim 1 , wherein:
the base insulation layer is provided in each of the first and second areas, and
a thickness of the base insulation layer in the thin-walled portion is less than a thickness of the base insulation layer in the second area.
3 . The flexure of claim 1 , further comprising:
a pillow on which the electronic component is disposed.
4 . The flexure of claim 1 , wherein
the electronic component is a slider, and
the wiring portion in the second area includes a terminal portion electrically connected to the slider.
5 . A suspension for a disk drive, comprising:
the flexure of claim 1 , and
a load beam which the flexure overlaps.
