The integrated lead suspension assembly comprises several improvements. An oversized
terminating pad for the electrical traces and a smaller adjacent insulation layer
on the flexure assembly enable laser solder ball bonding of the pads to the read/write
terminal contacts on the slider without clamping operation. Consequently, the tip
of the load beam can be made narrow for a structure that provides for head loading
and unloading functions, which improves the dynamic performance of the suspension
assembly. The flexure assembly is configured such that it requires no permanent
bending in its forming process, and any permanent bending required is done to the
load beam. The limiter that limits the travel of the flexure assembly is formed
on the load beam and it is bent to the functional position only after attachment
of the flexure assembly to the load beam. The limiter is configured and positioned
at the leading edge side of the slider to optimize the unloading process and to
minimize the possibility of disengagement of the limiter and the flexure assembly
during high shock environment. Asymmetric backing branches are provided for the
read and write traces in the flexure assembly located at the hinge area of the
load beam, the widths of which are sized to optimize the dynamic signal performance
of the read and write traces without impact on the vertical stiffness of the suspension.
Low profile flanges at 30-60 that bend from the plane of the load beam
are provided along the edges of the load beam to optimize bending stiffness and
flow induced vibration. Dimples are provided along the load beam to facilitate
insertion of a plastic head separation tool.
