Abstract
Impedance controlled trace flexure for a disk drive suspension comprising a laminated of a metal layer, an insulative film layer and at least one pair of conductive traces extending between spaced points on the flexure and adhered to the film layer in metal layer-spaced relation, at least one member of the pair being varied relative to the other pair member in that the length of at least one member between the spaced points is made greater than the distance between the spaced points or in width or thickness to control the impedance of the one pair member to match or not match the impedance of said the pair member.
