Disk drive suspension

A disk drive suspension comprising:

• a load beam;
• a flexure comprising a metal base secured to the load beam, and a slider mounted thereon;
• actuator elements configured to displace the slider;
• a slider terminal portion which is electrically connected to a terminal of the slider;
• a first terminal portion which is electrically connected to a first electrode of the actuator elements via an electrically conductive paste;
• and
• a second terminal portion which is electrically connected to a second electrode of the actuator elements and via an electrically conductive paste;
• wherein the slider terminal portion comprises a terminal conductor made of copper, a base nickel layer formed on the terminal conductor, and a gold-plating layer formed on the base nickel layer, and
• the first terminal portion comprises a first insulating layer having an electrical insulating property provided on the metal base, a first conductor made of copper which is formed on the first insulating layer, a first terminal element made of nickel which is provided on the first conductor and has a thickness greater than the base nickel layer, and a first gold-plating layer which is formed on the first terminal element and comprises a first roughening processed portion on its surface, and the first terminal element disposed between the first roughening processed portion and the first conductor constitutes a first protection means for preventing a part of copper of the first conductor from being exposed to the first roughening processed portion.
