Abstract:
1. A method of production of an integrated circuit contactor for testing an integrated circuit having terminals, the terminals of the integrated circuit being electrically connected to the contactor only when a pressure is exerted onto the contactor by the terminals of the integrated circuit, the method comprising the steps of: preparing a base of an insulating material on which a plurality of pads of a first conductive material are bonded at positions corresponding to positions of the terminals on the integrated circuit; bonding a wire of a second conductive material to each of the plurality of pads, and pulling the wire apart from a corresponding one of the plurality of pads so as to form a plurality of contacts of the second conductive material bonded to the plurality of pads, respectively, each contact having a projecting edge with a roughness produced by said step of bonding and pulling of the wire; and bonding, after said step of bonding and pulling of the wire, a second wire of a third conductive material to each of the plurality of contacts, and pulling the second wire apart from a corresponding one of the plurality of contacts so as to laminate the contacts of the second conductive material by a plurality of second contacts of the third conductive material, each second contact having a projecting edge with a roughness produced by said step of bonding and pulling of the second wire.
