Flexible Cable Bracket with Chamfer for Stacking Arm Type of Actuator

      Disclosed is an apparatus to improve the Head Suspension
Assembly (HSA) process, mainly stacking arm type of HSA with Planer
Suspension, by using flexible cable with a bracket which has chamfer
on the edge of its Planer Suspension side in the Hard Disk Drive
(HDD).

      Fig.1 shows the example of Stacking Arm type of Actuator used
in HDD.  Planer Suspensions(1) are stacked and fixed with Coil
Support(2), Spacer(3) and Washer(4) by Screw(5).  The flexible
cable(6) which has a bracket(7) is attached to the stacked Coil
Support(2) fit in the Planer Suspensions(1).  Fig. 2 shows the
outline of Flex Cable attachment and (A) in Fig. 2 shows the
chamfer-less type of bracket case  and (B) shows the chamfer type of
bracket case.

      The bracket outside is tapered off, and the bottom width of
the bracket, for example section X-X, is wider than the pitch of
Planer Suspensions to fit both pads of the flexible cable and Planer
Suspensions.

      Therefore, it is difficult to attach the flexible cable among
the Planer Suspensions because of their interference for case (A)
which causes the Planer Suspension damage.

      However, it is easy to attach the flexible cable for case (B)
by the chamfer(8).

      Furthermore, this chamfer(8) is valid for the rework process
after assembling, for example, replacement of any Planer
Suspension(s).

      Afterall, the chamfer on the ed...
