Abstract

A leadframe for encasing in a mold material includes a plurality of interconnected support members. A die pad is connected to the support members and includes a bottom surface. The die pad is configured to receive a die. A downset is connected to the die pad and positioned below the bottom surface. The downset includes at least one wall defining an interior volume for receiving a flow of the mold material to reduce the velocity of the mold material flow through the downset.
