Abstract
A system and method are disclosed for coupling a replacement micro-actuator to a drive arm suspension after a micro-actuator, such as a defective micro-actuator, has been detached from the suspension.
Claims32
A system to couple a second actuator element to a suspension element after a first actuator element has been detached from said suspension element, comprising:
- an electrically-conductive filler material applied to a suspension bond pad and a first bonding agent remaining on said suspension bond pad after bond separation to provide an improved bonding surface;
- and
- a second bonding agent coupling said remaining first bonding agent to a bond pad of a second actuator element.
