Abstract
An improved spindle motor flex cable and related mounting arrangement are provided for use in a computer disk drive unit to couple a disk drive spindle motor to associated drive electronics. The flex cable comprises a flexible ribbon base with multiple conductors at one side thereof, wherein the flex cable is supported on a substantially sealed disk drive housing with the conductor side presented generally toward the housing. An inboard end segment of the flex cable is folded back upon itself for outward exposure of inboard conductor ends to permit facilitated connection as by soldering to spindle motor leads protruding from the housing. An outboard end segment of the flex cable extends beyond a side margin of the disk drive housing to expose outboard ends of the conductors for connection as by soldering to a connector fitting oriented to face away from the housing for easy plug-in connection or the like to drive electronics located, for example, an adjacent circuit board.
