Patent ID: 8536718

Claim:
A method of manufacture of an integrated circuit packaging system comprising: providing a substrate having a first side with a material layer including parallel grooves within the material layer of a trench in a fillet region of the substrate; attaching an integrated circuit package to the substrate, sides of the integrated circuit package positioned substantially parallel to and adjacent the parallel grooves, wherein a first length of the parallel grooves adjacent opposing sides of the integrated circuit package is less than a length of the opposing sides, a second length of the parallel grooves adjacent other opposing sides is greater than a length of the other opposing sides, and the parallel grooves and the trench are formed around a perimeter of the integrated circuit package; exposing an embedded trench trace, of the substrate, from underneath the parallel grooves, the embedded trench trace having an area substantially equivalent to an area of the trench; forming a resin within the trench and between the substrate and the integrated circuit package, the resin contacting a top surface of the embedded trench trace exposed by the parallel grooves; and wherein: forming the resin includes exposing a visible side of the integrated circuit package completely from the resin, the visible side opposite and facing away from the first side of the substrate.
