Abstract
A method of manufacturing a magnetic head suspension assembly, wherein a wiring member for connecting a magnetic head element with a read/write amplifier circuit board is integrally formed with the suspension which includes the steps of (1) forming a flexible insulating base material on one surface of a springy metal layer by using a non-photosensitive polyimide resin layer or a photosensitive insulating resin layer; (2) producing a circuit wiring pattern on the top of the flexible insulating base material by plating and by using an electrically conductive metal thin film; (3) for forming a surface protecting layer on the surface of the circuit wiring pattern; (4) the springy metal layer; and (5) bending the springy metal layer to form a desired suspension.
