A method for locating head wires to the sides of actuator arms during the wire attachment operation is disclosed. This is accomplished using a unique tool instead of a feature in the part resulting in a cost savings.

combines the use of a custom designed wire guide
clip with the use of an ultra violet (UV) cured adhesive to produce a
very efficient, inexpensive, and gentle method for securing the heads
wires to the actuator arms. The wire guide is depicted in Fig. 1.
This wire guide is a one piece unit with features that fit between
the arms. These features are rounded at the ends to facilitate
merging it onto the actuator assembly by inserting it just in front
of the head/suspension assembly (HSA) mount block at an angle (Fig.
2), then sliding it along the arms while rolling the trailing edge
towards the actuator until the guide is fully engaged (Fig. 3). The
guide has tapered surfaces at the roots of these features to center
the wires on the edges of the actuator arms. Once the wire guide has
been merged onto the actuator assembly and the wires are centered on
the arms, then a clamp is positioned to hold down the wire guide.
Now the UV adhesive is applied to the head wires through an access
window in the wire guide. The assembly is then passed through a UV
light to cure the adhesive. This completes the process for which the
wire guide was intended. To complete the rest of the actuator
assembly process, the wir...
