ABSTRACT:
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.
