ABSTRACT:
A system and method are disclosed for improving hard drive actuator lead attachment. In one embodiment, an actuator board is coupled to an actuator flexible cable by a bonding agent, such as an anisotropic conductive film (ACF). In one embodiment, an actuator flexible cable is coupled to one or more actuator coil leads, such as by solder bump bonding, and the flexible cable/actuator coil coupling is embedded in an actuator frame, such as by polymer injection molding.
