Claims
- 1. A method of assembling an actuator arm, actuator board pads, and electrical connectors running along said actuator arm from said actuator board pads to a slider supporting a magnetic head comprising the steps of:
- (a) applying a thermoplastic or thermosetting dry film of anisotropic conductive adhesive (ACA) material to a set of actuator board bonding pads corresponding to said actuator arm;
- (b) holding a flexible circuit terminator supporting conductors for signals from said magnetic heads over said selected bonding pads and said ACA material; and
- (c) applying a hot tool over said flexible circuit terminator and said ACA material to provide heat and pressure to cause the film to soften to a flowable state and then to bond the flexible circuit terminator and ACA material to said actuator board bonding pads to establish both a mechanical support and an electrical connection between said flex terminator circuit and said actuator board bonding pads.
- 2. A method as claimed in claim 1 wherein said flexible circuit terminator extends along said actuator arm and over a suspension gimbal at a distal end of said actuator arm to said magnetic head, said slider supporting bonding pads on a top or front surface of said slider, applying a layer of ACA over said bonding pads, and bonding said flexible circuit terminator to said bonding pads to establish both a mechanical support and an electrical connection between said flex terminator circuit and said magnetic head.
- 3. A method as claimed in claim 2 including the further step of applying a further layer of said ACA material to a top surface of said slider, and pressure bonding said suspension gimbal to said top surface of said slider to establish both a mechanical support and a electrical grounding between said gimbal and said slider.
