Flexure including a heat sink and a dielectric layer under trace termination pads

A head/gimbal assembly comprising:

• a flexure including
• a metal base layer having
• two outrigger beams,
• a first crossbeam disposed between the two outrigger beams at a trailing end of the base layer,
• a second crossbeam disposed between the two outrigger beams,
• a base layer window disposed between the first and second crossbeams;
• a flexure tongue, including a slider mounting surface, extending from the second crossbeam, and
• a heat sink portion;
• a trace layer disposed over the base layer and including a plurality of conductive traces, each conductive trace having a curved section that terminates in a trace termination pad, each trace termination pad having an edge disposed closest to the flexure tongue;
• and
• a dielectric layer disposed between the trace and base layers and including
• a portion underlying the edges of the trace termination pads and overlying the heat sink portion, and
• a dielectric layer window disposed between the first and second crossbeams of the base layer;
• wherein the curved section of each conductive trace extends over the base layer window;
• and
• a head including
• a slider mounted on the flexure tongue, and
• a transducer having bonding pads, each bonding pad soldered to a respective trace termination pad by a solder ball.
