Abstract
A head stack assembly (HSA) for a disk drive includes an actuator body, at least one actuator arm extending from the actuator body, and a flexible printed circuit (FPC). The FPC includes first and second pluralities of electrically conductive FPC traces, each having a distal portion that terminates at a respective one of a plurality of FPC bond pads. The HSA also includes a head gimbal assembly (HGA) having a laminate flexure with a plurality of electrically conductive flexure bond pads that are bonded to the plurality of FPC bond pads. A width of at least one of the first plurality of FPC traces is greater than a width of at least one of the second plurality of FPC traces. The distal portion of at least one of the first plurality FPC traces includes a first opening therethrough, for example less than 1 mm from its corresponding FPC bond pad.
