Suspension and fabricating method thereof, head gimbal assembly and disk drive device

A head gimbal assembly comprising:

• a head slider having at least one front slider-bonding pad at a leading edge thereof and at least one rear slider-bonding pad at a trailing edge thereof;
• and
• a suspension comprising an attitude control layer positioned between the suspension and the head slider, the suspension further comprising:
• a flexure;
• a plurality of trace patterns disposed on the flexure;
• at least one front flexure-bonding pad disposed on the flexure at a position corresponding to the leading edge of the head slider and connected to one of the trace patterns, the front flexure-bonding pad being connected to the front slider-bonding pad by ball bonding;
• and
• at least one rear flexure-bonding pad disposed on the flexure at a position corresponding to the trailing edge of the head slider and connected to one of the trace patterns, the rear flexure-bonding pad being connected to the rear slider-bonding pad by ball bonding.

A disk drive device comprising:

• a head gimbal assembly;
• a drive arm to connect with the head gimbal assembly;
• a disk;
• and
• a spindle motor to spin the disk;
• wherein the head gimbal assembly comprises:
• a head slider having at least one front slider-bonding pad at a leading edge thereof and at least one rear slider-bonding pad at a trailing edge thereof;
• and
• a suspension, the suspension comprising:
• a flexure comprising an attitude control layer positioned between the flexure and the head slider;
• a plurality of trace patterns disposed on the flexure;
• at least one front flexure-bonding pad disposed on the flexure at a position corresponding to the leading edge of the head slider and connected to one of the trace patterns, the front flexure-bonding pad being connected to the front slider-bonding pad by ball bonding;
• and
• at least one rear flexure-bonding pad disposed on the flexure at a position corresponding to the trailing edge of the head slider and connected to one of the trace patterns, the rear flexure-bonding pad being connected to the rear slider-bonding pad by ball bonding.

A method for fabricating a suspension comprising steps of:

• (1) providing a flexure;
• (2) integrally forming a plurality of trace patterns and front and rear flexure-bonding pads, the front flexure bonding pad being connected to one of the trace patterns by ball bonding, and the rear flexure-bonding pad being connected to one of the trace patterns by ball bonding;
• (3) simultaneously disposing the trace patterns and the front and the rear flexure-bonding pads on the flexure;
• (4) providing an attitude control layer and covering the attitude control layer on the flexure.
