Abstract: A method of making a package is disclosed. The method may include forming bond pads on a first surface of a substrate, forming leads in the substrate by etching recesses in a second surface of the substrate, the second surface being opposite the first surface, and plating at least a portion of a top surface of the leads with a layer of finish plating. The method may also include thermosonically bonding the leads to a die by thermosonically bonding the finish plating to the die and encapsulating the die and the leads in an encapsulant.

Abstract: In providing electrical wire-like connections between at least one semiconductor die arranged on a semiconductor die mounting area of a substrate and an array of electrically-conductive leads in the substrate, pressure force is applied to the electrically-conductive leads in the substrate during bonding the wire-like connections to the electrically-conductive leads. Such a pressure force is applied to the electrically-conductive leads in the substrate via a pair of mutually co-operating force transmitting surfaces. These surfaces include a first convex surface engaging a second concave surface.
