ABSTRACT:
A trace interconnect assembly is designed for transmitting electrical signals to and from a head assembly in a hard disk drive. The interconnect assembly includes one or more single-layer thin, elongated, and generally flat substrate-free trace interconnects. The trace interconnects are new conductors etched out of a planar length of preferably a high tensile and high yield strength metal such as beryllium copper. They are shaped to match the surface topology of the suspension assembly. Trace interconnects have a rigid region and flexible regions that match a rigid region and flexible regions in the suspension assembly. Different additional elements include support braces, standoffs, trace tangs, bond pads, and stacked interconnects. Coupling a head assembly to the interconnect assembly creates a head interconnect harness. Methods of manufacture for the trace interconnect assembly, a multi-conductor stacked version, a head suspension assembly, and the head interconnect harness are disclosed.
