Abstract

A method of manufacture of an integrated circuit packaging system includes: providing a substrate; forming a mold gate on an upper surface of the substrate; mounting an integrated circuit to the substrate; and forming an encapsulant encapsulating the integrated circuit, the encapsulant having disruption patterns emanating from the mold gate and underneath a bottom plane of the integrated circuit.

Claims (19)

1. A method of manufacture of an integrated circuit packaging system comprising:

providing a substrate;

forming a mold gate on an upper surface of the substrate;

mounting an integrated circuit to the substrate; and

forming an encapsulant horizontally encapsulating the integrated circuit, the encapsulant having disruption patterns emanating from the mold gate and underneath a bottom plane of the integrated circuit, the disruption patterns having progressively larger diameters expanding from the mold gate toward the integrated circuit.

2. The method as claimed in claim 1 wherein forming the encapsulant includes forming the encapsulant with the mold gate encompassing a corner of the encapsulant and extending beyond the encapsulant in two axes.

3. The method as claimed in claim 1 wherein forming the encapsulant includes forming the encapsulant with the mold gate in direct contact with only a single side of the encapsulant and extending past a corner of the encapsulant.

4. The method as claimed in claim 1 wherein forming the encapsulant includes forming the encapsulant with the mold gate in direct contact with a side of the encapsulant and not extending past a corner of the encapsulant.

5. The method as claimed in claim 1 wherein forming the encapsulant includes forming the encapsulant with the mold gate extending past multiple corners of the encapsulant.

6. A method of manufacture of an integrated circuit packaging system comprising:

providing a substrate;

forming a mold gate on an upper surface of the substrate;

mounting an integrated circuit to the substrate;

forming an encapsulant horizontally encapsulating the integrated circuit, the encapsulant having disruption patterns emanating from the mold gate and underneath a bottom plane of the integrated circuit, the disruption patterns having progressively larger diameters expanding from the mold gate toward the integrated circuit, and a flat side in direct contact with the mold gate; and

connecting external interconnects below the substrate.

7. The method as claimed in claim 6 further comprising attaching a heat spreader to a top side of the encapsulant.

8. The method as claimed in claim 6 further comprising forming an under-fill between the integrated circuit and the substrate.

9. The method as claimed in claim 6 wherein forming the encapsulant includes forming the encapsulant having the disruption patterns overlapping.

10. The method as claimed in claim 6 further comprising attaching a heat spreader to the integrated circuit with a thermal interference material.
