Claim Text:
1. A method of manufacture of an integrated circuit packaging system comprising: providing a routable distribution layer on a leadframe; mounting an integrated circuit over the routable distribution layer; encapsulating with an encapsulation over the integrated circuit and the routable distribution layer; peeling the leadframe away from the routable distribution layer with a bottom distribution side of the routable distribution layer exposed from the encapsulation and having the characteristics of the leadframe peeled off therefrom; mounting an external interconnect on a bottom distribution side, of the routable distribution layer, coplanar with a bottom side of an attachment layer and the external interconnect below the integrated circuit; and applying a protective coat directly on the external interconnect, the routable distribution layer, and the encapsulation with the external interconnect having a connector height of the external interconnect greater than a coat height of the protective coat, and the external interconnect exposed from the protective coat.
