Abstract:
1. A method of manufacture of an integrated circuit packaging system comprising: forming a lead array having an innermost space with an innermost lead having an inner lead profile different around an inner non-horizontal side of the innermost lead and a middle lead adjacent to the innermost lead; placing an integrated circuit in the innermost space adjacent to the innermost lead, wherein the inner non-horizontal side is planar and facing the integrated circuit; applying a sealing filler in a sealing space directly and only between the innermost lead and the integrated circuit, the sealing filler having a filler bottom side coplanar with a die bottom side of the integrated circuit before completely forming the innermost lead and the middle lead with the innermost lead between the sealing filler and the middle lead; connecting an electrical interconnect to the integrated circuit and the middle lead; and forming a package encapsulation over the integrated circuit, the innermost lead, and the middle lead, the package encapsulation partially in the sealing space and directly on the sealing filler in the sealing space and the electrical interconnect.
