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.
