Method of manufacturing swage mount having a mixture of conductive material and a coating material
View Patent ↗A swage mount is manufactured for attaching a head suspension assembly to a head actuator arm for a hard disk drive. A conductive material is deposited on a predetermined part of the swage mount. A coating material is deposited on the swage mount including the predetermined part. Heat is applied to the swage mount, forming a mixture of the conductive material and the coating material. The mixture is conductive and supports a reliable connection between the swage mount and other disk drive components. Furthermore, the mixture enhances cleanliness by reducing particles shed from the swage mount. The conductive material is preferably gold, and the coating material is preferably nickel-based.
