20110068463 | INTEGRATED CIRCUIT PACKAGING SYSTEM WITH QUAD FLAT NO-LEAD PACKAGE AND METHOD OF MANUFACTURE THEREOF - A method of manufacture of an integrated circuit packaging system includes: providing a base array having terminals and an open region; attaching a coverlay layer directly on the base array; placing a component in the open region and directly on the coverlay layer; forming an encapsulation over the base array and the component; removing the coverlay layer to leave a plane of the terminals and a plane of the component partially exposed and substantially coplanar; and removing a portion of the base array between the terminals, the terminals electrically isolated. | 2011-03-24 |
20110068464 | INTEGRATED CIRCUIT PACKAGING SYSTEM WITH PACKAGE-ON-PACKAGE AND METHOD OF MANUFACTURE THEREOF - A method of manufacture of an integrated circuit packaging system includes: providing a base substrate; attaching a component over the base substrate; attaching a component interconnect to the base substrate and a perimeter of the component; mounting a stack device over the component; attaching a base exposed interconnect directly on the component and next to the component interconnect; and forming a base encapsulation over the base substrate, the component, and the component interconnect, the base exposed interconnect partially exposed from the base encapsulation. | 2011-03-24 |
