Abstract
A flexure is provided for a HGA suspension. The flexure includes a metal base layer, a trace layer, and a dielectric layer disposed between the trace and base layers. The metal base layer includes a heat sink portion. The trace layer includes a plurality of conductive traces, each conductive trace having a curved section that terminates in a trace termination pad. The dielectric layer includes a portion that underlies the trace termination pads and overlies the heat sink portion. The base layer and the dielectric layer each also include a window. The curved section of each conductive trace extends over the window of the base layer. The curved section of each conductive trace may at least partially extend over the window of the dielectric layer.
