Integrated circuit packaging system with package stacking and method of manufacture thereof
View Patent ↗A method of manufacture of an integrated circuit packaging system includes: providing a base package carrier; mounting an interposer over the base package carrier; forming a base package encapsulation over the base package carrier and the interposer with the base package encapsulation having a cavity for exposing the interposer; and forming a support recess in the base package encapsulation between a non-horizontal edge of the base package encapsulation and the cavity.
1. A method of a manufacture of an integrated circuit packaging system comprising:
providing a base package carrier;
mounting an interposer over the base package carrier;
forming a base package encapsulation over the base package carrier and the interposer with the base package encapsulation having an encapsulation top and a cavity for exposing the interposer; and
forming a support recess in the base package encapsulation between a non-horizontal edge of the base package encapsulation and the cavity with the support recess providing a continuous surface starting and ending at the encapsulation top.
2. The method as claimed in claim 1 further comprising providing system interconnects with a first spacing between each of the system interconnects different from a second spacing between a support structure and the system interconnects.
3. The method as claimed in claim 1 further comprising mounting a stackable package having a support structure in the support recess over the base package encapsulation.
4. The method as claimed in claim 1 wherein:
forming the base package encapsulation includes exposing the interposer; and
forming the support recess includes forming a recess bottom coplanar with the interposer top.
5. The method as claimed in claim 1 wherein forming the support recess includes forming the support recess having a depth for maintaining a stackable package planarity.
6. A method of a manufacture of an integrated circuit packaging system comprising:
providing a base package carrier;
mounting an interposer over the base package carrier;
forming a base package encapsulation over the base package carrier and the interposer with the base package encapsulation having an encapsulation top and a cavity for exposing the interposer;
forming a support recess in the base package encapsulation between a non-horizontal edge of the base package encapsulation and the cavity with the support recess providing a continuous surface starting and ending at the encapsulation top; and
mounting a stackable package having a support structure over the base package encapsulation.
7. The method as claimed in claim 6 wherein forming the support recess includes forming the support recesses evenly distributed on the base package encapsulation.
8. The method as claimed in claim 6 further comprising:
applying a recess adhesive in the support recess; and
wherein:
mounting the stackable package includes adhering the support structure, by the recess adhesive, in the support recess.
9. The method as claimed in claim 6 further comprising:
mounting a discrete component on the base package carrier; and
wherein:
forming the support recess includes forming the support recess above the discrete component.
10. The method as claimed in claim 6 wherein mounting the stackable package includes mounting the stackable package having a vertical gap between the stackable package and the base package.
11. An integrated circuit packaging system comprising:
a base package carrier;
an interposer over the base package carrier; and
a base package encapsulation over the base package carrier and the interposer with the base package encapsulation including:
an encapsulation top,
a cavity for exposing the interposer, and
a support recess formed between a non-horizontal edge of the base package encapsulation and the cavity, with the support recess providing a continuous surface starting and ending and at the encapsulation top.
12. The system as claimed in claim 11 further comprising system interconnects with a first spacing between each of the system interconnects different from a second spacing between a support structure and the system interconnects.
13. The system as claimed in claim 11 further comprising a stackable package having a support structure in the support recess over the base package encapsulation.
14. The system as claimed in claim 11 wherein:
the base package encapsulation includes the interposer exposed; and
the support recess includes a recess bottom coplanar with the interposer top.
15. The system as claimed in claim 11 wherein the support recess includes the support recess having a depth a depth for maintaining stackable package planarity.
16. The system as claimed in claim 11 further comprising a stackable package having a support structure mounted over the base package encapsulation.
17. The system as claimed in claim 16 wherein the support recess includes the support recesses evenly distributed on the base package encapsulation.
18. The system as claimed in claim 16 further comprising:
wherein:
the stackable package includes the support structure adhered, by the recess adhesive, in the support recess.
19. The system as claimed in claim 16 further comprising:
a discrete component mounted on the base package carrier; and
wherein:
the support recess includes the support recess formed above the discrete component.
20. The system as claimed in claim 16 wherein the stackable package includes the stackable package mounted having a vertical gap between the stackable package and the base package.
