Abstract
An electrical head interconnect assembly is fabricated for installation upon the suspension member supporting a magnetic read/write head over a rotating storage disk of a magnetic disk drive. A head interconnect is comprised of a film carrier strip upon which conducting elements are positioned and bonded. The carrier strip can be of plastic, metallic, cellulosic, or composite construction. The conducting elements, fabricated of 1 or more twisted or parallel lengths, are routed along a prepatterned carrier strip defining the X, Y, and Z coordinate positioning required to mate with a suspension member without manual routing or manipulation. In addition, the conducting elements are fixedly spaced with stripped insulation at both termination points of the interconnect (electronics and head) allowing prepositioned, automatable bonding to connective pads. A suspension member positioned and bonded within the strip at appendage sites, completes the installation of the conducting elements upon the suspension. The carrier then serves to secure the conductors and suspension within the protective framework of the strip and provides patterned tooling references until excised upon completion of head suspension assembly.
