Patent ID: 8841173

Claim:
A method of manufacture of an integrated circuit packaging system comprising: providing a leadframe with a grid lead, a plated land, and a support pad; connecting a first redistribution layer to the grid lead, forming a second redistribution layer over the support pad; mounting an integrated circuit over the second redistribution layer and the plated land, an active side of the integrated circuit facing the second redistribution layer, the second redistribution layer connecting the plated land to another plated land in an interior area between the integrated circuit and the support pad for distributing electric signals; applying an encapsulation directly on the first and second redistribution layers, the second redistribution layer separated from the active side of the integrated circuit exclusively by the encapsulation; forming a support pad residue on the bottom surface of the second redistribution layer by removing the support pad under the encapsulation and the second redistribution layer; and forming an insulation layer on the support pad residue and the grid lead.
