Abstract:
A disk drive suspension comprising a steel load beam and an electrical connector comprising a flexible circuit comprising dielectric plastic film and trace conductors disposed thereon across an air gap to said load beam, said dielectric film being a first dielectric film and having a thickness providing said electrical connector predetermined mechanical properties but inadequate to block capacitive coupling of said trace conductors with said steel load beam across said air gap, a second dielectric film in said air gap between said load beam and said flexible circuit, said second dielectric film having a thickness adequate to block said capacitive coupling, said second dielectric film being secured between said load beam and said electrical connector, said second dielectric film being free of trace conductors, whereby capacitive coupling between said load beam and said trace conductors is blocked without increasing the thickness of said first dielectric film or varying said predetermined mechanical properties.
