Patent ID: 8669649

Claim:
A method of manufacture of an integrated circuit packaging system comprising: forming a package paddle; forming a lead adjacent the package paddle, the lead having: (a) lead overhang protruding from the lead the lead overhang having: an overhang top, an overhang bottom, and an overhang non-horizontal side between the overhang top and the overhang bottom, wherein the overhang bottom width is greater than the overhang top width such that the lead overhang includes the overhang non-horizontal side tapering from the overhang top to the overhang bottom; (b) a lead middle having: a middle top, a middle bottom, and a middle non-horizontal side having a curvature, the middle non-horizontal side between the middle top and the middle bottom, wherein the middle top and the overhang bottom are co-planar, wherein the middle bottom width is greater than the middle top width such that the lead middle includes the middle non-horizontal side curving from the middle top to the middle bottom; and (c) a lead lower having: a lead ridge, a lower bottom, and a lower non-horizontal side between the lead ridge and the lower bottom, wherein the lead ridge and the middle bottom are co-planar, wherein the lead ridge width is greater than the lower bottom width such that the lead lower includes the lower non-horizontal side tapering from the lead ridge to the lower bottom, and wherein the lead ridge width is greater than the overhang bottom width; mounting an integrated circuit over the package paddle; connecting an electrical connector to the lead and the integrated circuit; and forming an encapsulation over the integrated circuit, the lead, and the package paddle, the encapsulation under the lead overhang.
