Abstract:
Quad Flat No-Lead (QFN) packages are provided. An embodiment of a QFN package includes a semiconductor chip including an active surface and an inactive surface, a plurality of leads, a plurality of wire bonds configured to couple the plurality of leads to the semiconductor chip, and a mold material including a mounting side and having a perimeter. The active surface is oriented toward the mounting side, the plurality of wire bonds are disposed between the active surface and the mounting side within the mold material, and the plurality of leads are exposed on the mounting side and are at least partially encapsulated within the perimeter of the mold material.
