Abstract
A method of bonding a magnetic disk drive head suspension to an actuator arm. The actuator arm has a boss hole therein and the suspension includes a base plate with an inside diameter or barrel therein. A thermoplastic cylindrical core is fabricated with a barrel therein. The suspension and actuator arm are clamped together to form a head stack assembly in which the base plate inside diameter is aligned with the boss hole in the actuator arm. The thermoplastic cylindrical core is passed through the base plate inside diameter and the boss hole in the actuator arm. A heating tool, such as an ultrasonic horn is passed through the barrel of the cylindrical core and heated causing the cylindrical core expand and bond to the base plate inside diameter and to the actuator arm boss hole.
