Abstract

A method of manufacture of an integrated circuit packaging system includes: mounting an integrated circuit over a package carrier; mounting a conductive connector over the package carrier; forming an encapsulation over the integrated circuit, the encapsulation having a recess exposing the conductive connector; and mounting a heat slug over the encapsulation, the heat slug having an opening with an opening width greater than a recess width of the recess, the opening exposing a portion of a top surface of the encapsulation.

Claims (47)

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

mounting an integrated circuit over a package carrier;

mounting a conductive connector over the package carrier;

forming an encapsulation over the integrated circuit, the encapsulation having a recess exposing the conductive connector; and

mounting a heat slug over the encapsulation, the heat slug having:

an opening with an opening width greater than a recess width of the recess, the opening exposing a portion of a top surface of the encapsulation,

a teeth gap exposing a bottom conductive connector, and

a teeth extension of the heat slug covering a bottom gap between a plurality of the bottom conductive connector.

2. The method as claimed in claim 1 wherein mounting the heat slug includes mounting the heat slug having a sidewall in direct contact with an encapsulation side and a carrier side.

3. The method as claimed in claim 1 wherein mounting the heat slug includes mounting the heat slug having a sidewall with a step, the step over a component side of the package carrier.

4. The method as claimed in claim 1 wherein mounting the heat slug includes mounting the heat slug having an inner leg between the conductive connector and the integrated circuit over a component side of the package carrier.

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

mounting an integrated circuit over a package carrier;

mounting a conductive connector over the package carrier;

forming an encapsulation over the integrated circuit, the encapsulation having a recess exposing the conductive connector; and

mounting a heat slug over the encapsulation, the heat slug having:

an opening with an opening width greater than a recess width of the recess, the opening exposing a portion of a top surface of the encapsulation and the conductive connector,

a teeth gap exposing a bottom connector, and

a teeth extension of the heat slug covering a bottom gap between a plurality of the bottom conductive connector.

6. The method as claimed in claim 5 wherein mounting the heat slug includes mounting the heat slug having an overhang over the top surface of the encapsulation.

7. The method as claimed in claim 5 wherein mounting the heat slug includes mounting the heat slug formed by a single integral structure having a slug top and a sidewall with an adhesive in direct contact with the slug top and the sidewall.

8. The method as claimed in claim 5 wherein mounting the heat slug includes mounting the heat slug with a sidewall directly on a mounting side of a mounting carrier.

9. The method as claimed in claim 5 further comprising mounting a stackable package having a package side over the heat slug, the package side coplanar with a peripheral side of the sidewall.

10. An integrated circuit packaging system comprising:

a package carrier;

an integrated circuit over the package carrier;

a conductive connector over the package carrier;

an encapsulation over the integrated circuit, the encapsulation having a recess exposing the conductive connector;

a heat slug over the encapsulation, the heat slug having an opening with an opening width greater than a recess width of the recess, the opening exposing a portion of a top surface of the encapsulation;

a bottom conductive connector attached to the package carrier; and

wherein the heat slug includes:

a teeth gap exposing the bottom conductive connector; and

a teeth extension covering the bottom gap between a plurality of the bottom conductive connector.

11. The system as claimed in claim 10 wherein the heat slug includes a sidewall in direct contact with an encapsulation side and a carrier side.

12. The system as claimed in claim 10 wherein the heat slug includes a sidewall having a step, the step over a component side of the package carrier.

13. The system as claimed in claim 10 wherein the heat slug includes an inner leg between the conductive connector and the integrated circuit.

14. The system as claimed in claim 10 wherein the further exposes the conductive connector.

15. The system as claimed in claim 14 wherein the heat slug includes an overhang over the top surface of the encapsulation.

16. The system as claimed in claim 14 further comprising:

an adhesive directly on the top surface of the encapsulation; and

wherein:

the heat slug is a single integral structure having a slug top and a sidewall in direct contact with the adhesive.

17. The system as claimed in claim 14 further comprising:

a mounting carrier having a mounting side; and

wherein:

the heat slug includes the heat slug with a sidewall directly on the mounting side of the mounting carrier.

18. The system as claimed in claim 14 further comprising a stackable package having a package side over the heat slug, the package side coplanar with a peripheral side of the sidewall.
