摘要： Described is a preamp flex cable for use in a hard drive. The flex cable incorporates a stiffener layer operable to provide a mechanical support, an insulating layer provided over the stiffener layer and having at least one via provided therein to expose the stiffener layer, and at least one conductive layer provided over the insulating layer. The at least one conductive layer forms an electrical circuit and at least one heat removing element that extends through the via and establishes a contact with the stiffener layer. In one implementation, the heat removing element includes a rectangular plate having a recessed center portion and an edge portion. The recessed center portion protrudes through the at least one via in the insulating layer to mechanically couple with the stiffener. In another implementation, the heat removing element includes first portion and second rectangular portions. The first portion protrudes through the at least one via in the insulating layer to thermally couple with the stiffener and the second portion is disposed over the insulating layer, such that the second portion can be thermally coupled to the preamp.

摘要： A first insulating layer is formed on a suspension body. A write wiring trace is formed on the first insulating layer. A second insulating layer is formed on the first insulating layer to cover the write wiring trace. A write wiring trace and read wiring traces are formed on the second insulating layer. The write wiring trace is arranged above the write wiring trace. The write wiring trace includes a conductor layer and reinforcing alloy layers. The reinforcing alloy layers are sequentially formed to cover an upper surface and side surfaces of the conductor layer.
