摘要： A disk drive head suspension flexure having a gimbal region and a tail includes a metal base layer, an insulation layer over the base layer and two or more pairs of adjacent traces extending over the insulation layer from the gimbal region to the tail. Each trace includes terminals on the gimbal region and tail. Two or more conductive metal signal transmission planes are embedded within the insulation layer and extend from the gimbal region to the tail between the pairs of traces and metal base layer. Each of the embedded signal transmission planes has a width extending across a width of a pair of the traces. Terminals on the gimbal region and tail are coupled to the signal transmission planes by connection vias extending through the insulation layer.

摘要： A method for efficiently producing low resistance electrical contacts between stainless steel and conductive layers in integrated lead suspensions and components. The method includes applying an amount of current for a period of time which is effective to reduce the resistance to a desired level. One embodiment of the invention includes applying a 100 mA current for 16 msec to a contact formed by thermosetting conductive epoxy. Resistance levels below 1 ohm can be achieved.

摘要： An integrated lead flexure includes traces with windowed or reduced width portions. The flexure includes a metal base layer with a plurality of apertures, an insulating layer on the metal base layer, and one or more conductive traces formed on the insulating layer and extending over the metal base layer and the plurality of apertures. Backed portions of the one or more conductive traces that extend over the metal base layer have a first width, and unbacked portions of the one or more conductive traces that extend over the plurality of apertures have a second width that is less than the first width.
