Abstract

A ball grid array package stacking system includes: forming a heat spreader having a centrally located access port; mounting a substrate in the heat spreader for providing a connection pad in the centrally located access port; coupling an integrated circuit die to the substrate; and coupling a system interconnect to the integrated circuit die, the connection pad, or a combination thereof.

Claims (35)

1. A method of manufacturing a ball grid array package stacking system comprising:

forming a heat spreader having a standoff leg and a centrally located access port;

mounting a substrate in the heat spreader for providing a connection pad in the centrally located access port, and with a gap between the substrate and the standoff leg of the heat spreader;

coupling an integrated circuit die to the substrate; and

coupling a system interconnect through a system pad, on a bottom of the substrate and adjacent to the heat spreader, to the integrated circuit die, the connection pad, or a combination thereof.

2. The method as claimed in claim 1 further comprising coupling a stacked package to the connection pad.

3. The method as claimed in claim 1 further comprising coupling a stacked die to the connection pad.

4. The method as claimed in claim 1 further comprising coupling a discrete component to the connection pad.

5. The method as claimed in claim 1 further comprising positioning a mounted substrate in the centrally located access port.

6. A method of manufacturing a ball grid array package stacking system comprising:

forming a heat spreader having a centrally located access port including forming a standoff leg;

mounting a substrate in the heat spreader for providing a connection pad in the centrally located access port including forming an array of the connection pads, and with a gap between the substrate and the standoff leg of the heat spreader;

coupling an integrated circuit die to the substrate including connecting an electrical interconnect between the integrated circuit die and the substrate; and

coupling a system interconnect through a system pad, on a bottom of the substrate and adjacent to the heat spreader, to the integrated circuit die, the connection pad, or a combination thereof including coupling a solder ball, a solder bump, a solder column, or a stud bump.

7. The method as claimed in claim 6 further comprising coupling a stacked package to the connection pad for forming a package stack including coupling a stacked integrated circuit, the integrated circuit die, the system interconnect, or a combination thereof.

8. The method as claimed in claim 6 further comprising coupling a stacked die to the connection pad including applying a sealing material between the stacked die and the substrate.

9. The method as claimed in claim 6 further comprising coupling a discrete component to the connection pad including coupling a resistor, a capacitor, an inductor, a diode, a transistor, or a voltage regulator to the integrated circuit die, the system interconnect, or a combination thereof.

10. The method as claimed in claim 6 further comprising positioning a mounted substrate in the centrally located access port including forming a molded filler, in the centrally located access port, between the mounted substrate and the heat spreader.

11. A ball grid array package stacking system comprising:

a heat spreader having a standoff leg and a centrally located access port;

a substrate mounted in the heat spreader for providing a connection pad in the centrally located access port, and with a gap between the substrate and the standoff leg of the heat spreader;

an integrated circuit die coupled to the substrate; and

a system interconnect coupled through a system pad, on a bottom of the substrate and adjacent to the heat spreader, to the integrated circuit die, the connection pad, or a combination thereof.

12. The system as claimed in claim 11 further comprising a stacked package coupled to the connection pad.

13. The system as claimed in claim 11 further comprising a stacked die coupled to the connection pad.

14. The system as claimed in claim 11 further comprising a discrete component coupled to the connection pad.

15. The system as claimed in claim 11 further comprising a mounted substrate positioned in the centrally located access port.

16. The system as claimed in claim 11 further comprising:

an array of the connection pads in the centrally located access port;

an electrical interconnect between the integrated circuit die and the substrate; and

a solder ball, a solder bump, a solder column, or a stud bump coupled to the integrated circuit die, the connection pad, or a combination thereof.

17. The system as claimed in claim 16 further comprising a stacked package coupled to the connection pad to form a package stack includes a stacked integrated circuit, the integrated circuit die, the system interconnect, or a combination thereof electrically connected.

18. The system as claimed in claim 16 further comprising a stacked die coupled to the connection pad includes a sealing material between the stacked die and the substrate.

19. The system as claimed in claim 16 further comprising a discrete component coupled to the connection pad includes a resistor, a capacitor, an inductor, a diode, a transistor, or a voltage regulator coupled to the integrated circuit die, the system interconnect, or a combination thereof.

20. The system as claimed in claim 16 further comprising a mounted substrate positioned in the centrally located access port includes a molded filler, formed in the centrally located access port, between the mounted substrate and the heat spreader.
