Head suspension flexure with conductive polymer layer

摘要

A flexure has a substrate made of a thin conductive metal plate, a base insulating layer made of flexible resin formed on the substrate, wiring patterns formed on the base insulating layer and connected to a slider mount, and a cover insulating layer formed over the wiring patterns. The flexure is substantially coated with a conductive polymer layer having a thickness in the range of 18 to 130 nm. The flexure prevents electrostatic accumulation and ion migration.
