| titleOfInvention |
Laminate for HDD suspension and its manufacture |
| abstract |
This invention relates to laminates for use in HDD suspensions which are composed of a stainless steel base material and successive layers formed thereon of polyimides and an electrical conductor and in which the linear expansion coefficient of the polyimide layer is controlled in the range of 1x10-5/° C. to 3x10-5/° C. and the adhesive strength between stainless steel and polyimide and that between polyimide and electrical conductor are controlled at 0.5 kg/cm or more. This invention also relates to a process for preparing laminates for use in HDD suspensions comprising applying a solution of polyimide precursors or polyimides to a stainless steel base material with a thickness of 10 to 70 mum in one layer or more, drying, performing heat treatment at 250° C. or more to form a layer of polyimides with a thickness of 3 to 20 mum and a linear expansion coefficient of 1x10-5/° C. to 3x10-5/° C. and contact-bonding said layer of polyimides under heat to a layer of electrical conductor with a thickness of 3 to 20 mum.Laminates of this invention for use in HDD suspensions are practically free of deflection during etching and are suited for integrally-wired HDD suspensions. |
