Integrated circuit packaging system with underfill and method of manufacture thereof

摘要

A method of manufacture of an integrated circuit packaging system includes: providing a substrate with a projection formed along a perimeter of a first surface of the substrate; mounting an integrated circuit over the first surface; forming a protruding interconnect over the first surface between the projection and the integrated circuit; and forming an underfill between the integrated circuit and the projection with a uniform height, the uniform height of the underfill less than a height of the projection.
