Abstract
An apparatus connects a flexible circuit to an actuator arm of a disc drive. The actuator arm supports a transducer head assembly, and the flexible circuit includes an electrical circuit supporting structure supporting a first electrical circuit coupled to the transducing head assembly. The apparatus comprises a solder joint. In one embodiment, the solder joint comprises a pin, respective first and second pin receiving holes in the actuator arm and supporting structure, and a solder connection between the pin and the supporting structure. Connecting the flexible circuit to the actuator arm entails inserting the pin through the second pin receiving hole, press-fitting the pin into the first pin receiving hole, and soldering it to the supporting structure. Another embodiment includes a solder connection between a ground plane on the supporting structure and the pin.
