Patent ID: 8035924

Claim:
A suspension for disc drive, comprising: a base plate; a load beam; and a flexure which is disposed along the load beam and includes a slider on a distal end portion thereof, wherein the flexure includes a metal base member and a circuit member which is disposed along the metal base member, extends in a longitudinal direction of the load beam, and is electrically connected to the slider, wherein the circuit member includes: (i) a resin base member comprising an electrically insulating resin, the resin base member being formed on the metal base member, (ii) at least a pair of conductors of predetermined circuit patterns comprising a copper layer deposited on the resin base member, and (iii) a resin cover member which covers the conductors, wherein each of the conductors has a trapezoid shape in cross section such that a width of a first surface of the conductor which faces the resin base member is greater than a width of a second surface of the conductor on a side opposite from the resin base member, and wherein the resin cover member comprises a pair of side surfaces extending along each side surface of the conductors, a flat surface formed between the pair of side surfaces of the resin cover member, the flat surface extending along the second surface of the conductor, and an inverted trapezoid resin portion having an inverted trapezoid shape in cross section, the inverted trapezoid resin portion being filled between the pair of conductors.
