Leadframe with pad anchoring members and method of forming the same
Abstract:
A leadframe having extensions around an outer edge of a die pad are disclosed. More specifically, leadframes are created with a flange formed at the outer edge of the die pad and extending away from the die pad. The flange is bent, such that it is positioned at an angle with respect to the die pad. Leadframes are also created with anchoring posts formed adjacent the outer edge of the die pad and extending away from the die pad. The anchoring posts have a central thickness that is less than a thickness of first and second portions opposite the central portion. When the leadframe is incorporated into a package, molding compound completely surrounds each flange or anchoring post, which increases the bond strength between the leadframe and the molding compound due to increased contact area. The net result is a reduced possibility of delamination at edges of the die pad.
