Abstract:
A bond-wire cutting device for cutting off a part of a bond-wire that extends beyond a bonding contact area after a bonded connection has been produced, with a knife that can be moved with a movement component substantially perpendicular to the surface of a substrate and hence to the bonding contact area, wherein the knife is elastically mounted so as to be yielding to a limited extent with respect to the movement component substantially perpendicular to the substrate surface, in such a way that force acting on a cutting edge of the knife when the knife encounters the substrate is limited to a prespecified peak value and wherein the knife is connected by way of a bearing comprising an elastomer element that under pressure can change its shape elastically or is compressible to a force-transfer element that transmits the substantially perpendicular movement component.
