Abstract

The small size of components for new hard files has made conventional (i.e., high manual labor content, but tool-aided) head suspension assembly (HSA) manufacturing techniques expensive and does not deliver the tight tolerances required by the new miniaturized designs. Disclosed is an invention which aids the low cost manufacture of the new miniaturized designs.

Toolblock for Small Part Manufacture

      The small size of components for new hard files has made
conventional (i.e., high manual labor content, but tool-aided) head
suspension assembly (HSA) manufacturing techniques expensive and does
not deliver the tight tolerances required by the new miniaturized
designs.  Disclosed is an invention which aids the low cost
manufacture of the new miniaturized designs.

      As can be seen from Fig. 1, a first generation tool design was
quite simple.  Pin details 9 and 10 located the suspension by pin 9
engaging a V feature in the load beam, and pin 10 engaging a slot in
the rear of the load beam.  HSA clamp 6 provided both hold-down of
the suspension to the toolblock, as well as registering the
suspension back so that the front pin 9 would be securely in contact
with the suspension front alignment V.

      The slider was registered in correct position at its front by
alignment pin 11, and on its side by tool plate 2 and clamp detail 4,
and underneath by slider riser 3.  Slider clamp pin 8 and slider
riser pin 12 provided activation of the slider clamp to both open and
close this mechanism.

      After preliminary processing, the slider would be inserted into
the toolblock from the open front end, the suspension bent down over
the end of the slider, and the wires ultrasonically bonded to the
slider.  Next, the front stringing flag would be sheared off close to
the slider by a secondary shear coming down on either side of the...
