Abstract
A flexible circuit incorporating electrostatic discharge (ESD) limiting features and being suitable for use in the fabrication of hard disk drives for computer applications. Conductive polymer strips are implemented to enhance the static dissipative characteristics of the flexible circuit and to protect magnetorestistive (MR) heads of a hard disk drive (HDD) from damage during the manufacture of the head gimbal assembly (HGA) of the HDD.
