Abstract

An integrated circuit package system includes providing a substrate having an integrated circuit die thereon. A support is provided on the substrate. A heat slug having a tie bar is positioned by the tie bar on the support. The substrate and the integrated circuit die are encapsulated with an encapsulant, the encapsulant in contact with the heat slug. The substrate, heat slug, and encapsulant are singulated to remove the support.

Claims (30)

1. A method for manufacturing an integrated circuit package system comprising:

providing a substrate having an integrated circuit die thereon;

providing a support on the substrate;

positioning a heat slug having a tie bar by the tie bar on the support;

encapsulating the substrate and the integrated circuit die with an encapsulant, the encapsulant filling all of the space between the integrated circuit die and the heat slug; and

singulating the substrate through the tie bar to remove the support.

2. The method for manufacturing the integrated circuit package system as claimed in claim 1 , wherein:

providing a support on the substrate provides a dotting of adhesive on the substrate.

3. The method for manufacturing the integrated circuit package system as claimed in claim 1 , wherein positioning the heat slug having a tie bar, comprises:

positioning a heat slug having a main body portion and a tie bar substantially centrally located along each side of the main body portion.

4. The method for manufacturing the integrated circuit package system as claimed in claim 1 , wherein positioning the heat slug having a tie bar, comprises:

positioning a heat slug having a main body portion and a tie bar having a thickness of greater than or equal to about half the thickness of the main body portion.

5. The method for manufacturing the integrated circuit package system as claimed in claim 1 , wherein positioning the heat slug having a tie bar, comprises:

positioning a heat slug having a main body portion and a pair of tie bars located along each side of the main body portion.

6. A method for manufacturing an integrated circuit package system comprising:

providing a substrate having a plurality of contacts;

attaching an integrated circuit die to the substrate;

wire bonding the integrated circuit die to the contacts;

providing a support on the substrate outside the location of the plurality of contacts;

positioning a heat slug having a plurality of tie bars by the tie bars on the support;

encapsulating the substrate and the integrated circuit die with an encapsulant, the encapsulant filling all of the space between the integrated circuit die and the heat slug; and

singulating the substrate, heat slug, and encapsulant to remove the support.

7. The method for manufacturing the integrated circuit package system as claimed in claim 6 , wherein positioning the heat slug having a plurality of tie bars, comprises:

positioning a heat slug having a main body portion and a tie bar substantially centrally located along each side of the main body portion.

8. The method for manufacturing the integrated circuit package system as claimed in claim 6 , wherein positioning the heat slug having a tie bar, comprises:

positioning a heat slug having a main body portion and a tie bar having a thickness of greater than about half the thickness of the main body portion.

9. The method for manufacturing the integrated circuit package system as claimed in claim 6 , wherein positioning the heat slug having a plurality of tie bars, comprises:

positioning a heat slug having a main body portion with upper and lower surfaces and having the plurality of tie bars located at least one of flush with the upper surface of the heat slug, flush with the lower surface of the heat slug, and intermediate the upper and lower surfaces of the heat slug.

10. The method for manufacturing the integrated circuit package system as claimed in claim 6 , wherein positioning the heat slug having a plurality of tie bars, comprises:

positioning a heat slug having a main body portion and a pair of tie bars located along each side of the main body portion.
