Integrated circuit packaging system with external wire connection and method of manufacture thereof
View Patent ↗A method of manufacture of an integrated circuit packaging system includes: providing a package carrier; mounting an integrated circuit to the package carrier; forming an external wire on the package carrier and adjacent to the integrated circuit; forming an encapsulation on the package carrier over the external wire; and forming a hole in the encapsulation with the external wire and a portion of the package carrier exposed from the encapsulation.
1. A method of manufacture of an integrated circuit packaging system comprising:
providing a package carrier;
mounting an integrated circuit to the package carrier;
forming an external wire on the package carrier and adjacent to the integrated circuit;
forming an encapsulation on the package carrier over the external wire; and
forming a hole in the encapsulation with the external wire and a portion of the package carrier exposed from the encapsulation.
2. The method as claimed in claim 1 wherein forming the external wire includes forming the external wire in a loop configuration with both ends of the external wire attached to the package carrier.
3. The method as claimed in claim 1 further comprising forming a support conductor on the package carrier, the support conductor surrounding a bottom portion of the external wire leaving a top portion of the external wire exposed.
4. The method as claimed in claim 1 wherein forming the external wire includes forming the external wire, having a lower portion and a tip portion, the lower portion attached to the package carrier and wider than the tip portion.
5. The method as claimed in claim 1 further comprising:
mounting a mounting integrated packaging system over the encapsulation; and
forming a package interconnect between the mounting integrated packaging system and the external wire.
6. A method of manufacture of an integrated circuit packaging system comprising:
providing a package carrier;
mounting an integrated circuit to the package carrier;
forming an external wire on the package carrier and adjacent to the integrated circuit;
forming an encapsulation on the package carrier over the external wire; and
forming a hole in the encapsulation exposing a portion of the package carrier and exposing the external wire below the top horizontal surface of the encapsulation.
7. The method as claimed in claim 6 wherein forming the hole in the encapsulation includes forming non-horizontal side walls along the encapsulation.
8. The method as claimed in claim 6 further comprising:
mounting a mounting integrated packaging system over the encapsulation; and
forming a package interconnect between the mounting integrated packaging system and the external wire with the package interconnect surrounding the external wire.
9. The method as claimed in claim 6 further comprising:
forming a support conductor on the package carrier, the support conductor surrounding a bottom portion of the external wire leaving a top portion of the external wire exposed;
mounting a mounting integrated packaging system over the encapsulation; and
forming a package interconnect between the mounting integrated packaging system and the external wire with the package interconnect surrounding top portion of the external wire and in direct contact with the support conductor.
10. The method as claimed in claim 6 further comprising:
mounting a mounting integrated packaging system over the encapsulation; and
forming a package interconnect between the mounting integrated packaging system and the external wire with the package interconnect in direct contact with the package carrier.
