a reference plane is added to the freestanding conductors of a wireless suspension to maintain a continuous reference plane therein . post processing steps to the flexure are used after the underlying steel has been etched and prior to any forming or welding steps . two screens are used to add an insulator layer and a conductor layer , such as copper , in the areas of the freestanding conductors . the insulator screen is sized to allow an insulator to overlap the original polyimide . the copper screen for the reference has a slightly longer screen pattern than the insulator screen . the conductor screen is sized such that the reference will overlap the insulator and make contact with the underlying steel at both ends of the freestanding conductors .
