    摘要： A semiconductor package comprises a substrate that utilizes one or more pins to form external interconnects. The pins are bonded to bonding pads on the substrate by solder. The pins may each has a pin head that may have a bonding surface, wherein the bonding surface may comprises a center portion and a side portion that is tapered away relative to the center portion. In some embodiments, the bonding surface may comprise a round shape. In some embodiments, a gas escape path may be provided by the shape of the bonding surface to increase pin pull strength and/or solder strength. The package may further comprise a surface finish that may comprise a palladium layer with a reduced thickness to reduce the amount of palladium based IMC precipitation into the solder.
