Abstract
Integrated conductor suspensions are fabricated by progressively etching a suspension shape in a preformed laminate of copper, and stainless steel adhering to an intermediate resin layer, including defining pairs of signal lines in the copper layer having exposed sides and top, and coating these exposed sides and top with an adherent layer of gold down to the resin layer against corrosion in ambient corrosive environments.

Method for the fabrication of an integrated conductor suspension in a preformed laminate comprising a copper layer, a metal support layer, and an adherent resin layer therebetween, including defining a suspension shape in said copper layer, shaping said resin layer to conform to said copper suspension shape, defining pairs of signal lines within said suspension shape in said copper layer in a manner leaving each of said signal lines with an exposed top and exposed sides, and coating an adherent layer of gold on said tops and sides of said signal lines in protective relation against exposure of any portion thereof to ambient corrosive environments.
Method for the fabrication of an integrated conductor suspension, including defining a suspension shape in a preformed laminate comprising a copper layer, a metal support layer, and an adherent resin layer therebetween by a sequence of etching steps which successively shape said copper layer, shape said resin layer to conform to said copper suspension shape, and define pairs of signal lines within said suspension shape in said copper layer in a manner leaving each of said signal lines with an exposed top and exposed sides, thereafter coating an adherent layer of gold on said tops and sides of said signal lines in protective relation against exposure of any portion thereof to ambient corrosive environments, and etching said metal support layer to conform to said suspension shape.
An integrated conductor suspension comprising a suspension-shaped laminate of a copper layer, a metal support layer and an adherent resin layer therebetween, pairs of signal lines defined in said copper, said signal lines each having an exposed top and exposed sides, and a coating of gold on said tops and sides of said signal fines in protective relation against exposure of any portion thereof to ambient corrosive environments.
