Abstract

An integrated circuit package system includes providing a substrate having a first plurality of conductive traces having a first width. An integrated circuit die is attached to the substrate. A mold clamp line is identified on the substrate. A critical area around the mold clamp line is determined. A plurality of widened conductive traces having a second width in the critical area is provided. An encapsulant encapsulates the integrated circuit die.
