Abstract

Disclosed are flexture structures of Head Suspension Assembly (HSA) for raising their bonded strength with magnetic small-sized sliders. The principle of the disclosed flexture structures is made up of redesigning stiffeners and cantilevers of a flexture and extending a tongue area for better slider-flexture bonding.

Flexture for Small-Sized Slider with Extended Bonded Tongue

      Disclosed are flexture structures of Head Suspension Assembly
(HSA) for raising their bonded strength with magnetic small-sized
sliders.  The principle of the disclosed flexture structures is made
up of redesigning stiffeners and cantilevers of a flexture and
extending a tongue area for better slider-flexture bonding.

      The Figure shows the three flexture examples of the disclosed
structures with a conventional flexture.  The upper row illustrates
stiffeners and Cantilever Length for the respective flexture designs,
and the lower does their bonded areas.  There are three types of the
disclosed flexture structures: acute angle stiffner type,
perpendicular stiffner type and obtuse angle stiffner type.  With the
above order of the types, the tongue areas are gradually extended and
the largest bonded area, that is, the highest bonded strength can be
achieved in the Obtuse angle stiffner type.  The basic gimbal
mechanism of a suspension assembly is kept with the disclosed
flexture structures, but to make the mechanism equivalent to a
current level, some adjustment work such as weld spots location
change may be needed like the Obtuse angle stiffner type shown in the
Figure.  Currently, there are two types of pull tests, Peel and
Shear, to know a slider flexture bonded strength and the disclosed
flexture structures can show a remarkable performance not only in the
Shear, but also in the Peel test...
