Abstract:
1. A method of manufacturing an integrated circuit packaging system comprising: providing a sacrificial carrier assembly having a stack interconnector thereover; mounting an integrated circuit having a connector over the sacrificial carrier assembly with the connector over the stack interconnector; dispensing an underfill material between the sacrificial carrier assembly and the integrated circuit with the underfill material substantially free of a void, the underfill material applied entirely over the sacrificial carrier assembly with a uniform distribution; encapsulating the integrated circuit over the sacrificial carrier assembly and the underfill material with an encapsulating material, the encapsulating material having a different material composition than the underfill material; exposing the stack interconnector by removing the sacrificial carrier assembly; and forming a base array including a resistive circuit, a routing trace, and a film layer over the underfill material and the stack including:
