Abstract

An integrated circuit packaging system and method of manufacture thereof includes: leads and a paddle; a first encapsulant molded between the leads and the paddle, the first encapsulant thinner than the leads; a non-conductive layer over the paddle; and conductive traces directly on the leads, the first encapsulant, and the non-conductive layer.

Claims (92)

1. A method of manufacture of an

integrated circuit packaging system comprising:

forming a leadframe including leads and a paddle;

molding a first encapsulant in the leadframe between the leads and the paddle, the first

encapsulant thinner than the leads;

forming a non-conductive layer over the paddle; and

forming conductive traces each having a side, the side directly on the lead, the first

encapsulant, and the non-conductive layer.

2. The method as claimed in claim 1 further comprising:

attaching a first module to the conductive traces; and

encapsulating the first module in a second encapsulant.

3. The method as claimed in claim 1 wherein:

forming the non-conductive layer forms the non-conductive layer with an opening therein over a portion of the paddle; and

further comprising:

conductively bonding a first module to the conductive traces on the non-conductive layer and to the paddle through the opening in the non-conductive layer.

4. The method as claimed in claim 1 further comprising:

conductively bonding a first module to the conductive traces;

attaching a second module to the first module;

conductively bonding the second module to the leads; and

further encapsulating the first module and the second module in a second encapsulant.

5. The method as claimed in claim 1 further comprising:

conductively bonding a first module to the conductive traces;

attaching a second module to the first module, the second module having a substrate conductively connected to the leads;

further encapsulating the second module in a configured encapsulant exposing an exposed portion of the substrate; and

conductively bonding a third module to the exposed portion of the substrate.

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

forming a leadframe including leads and a paddle;

molding a first encapsulant in the leadframe between the leads and the paddle, the first encapsulant coplanar with the top and bottom surfaces of the paddle;

forming a non-conductive layer over the paddle;

forming straight or bent conductive traces each having a side, the side directly on the lead, the first encapsulant, and the non-conductive layer; and

separating the leads from each other.

7. The method as claimed in claim 6 further comprising:

conductively bonding a flip chip module to the conductive traces; and

further encapsulating the flip chip module in a second encapsulant.

8. The method as claimed in claim 6 wherein:

forming the non-conductive layer forms the non-conductive layer with an opening therein over a portion of the paddle; and

further comprising:

conductively bonding a flip chip module to the conductive traces on the non-conductive layer and to the paddle through the opening in the non-conductive layer.

9. The method as claimed in claim 6 further comprising:

conductively bonding a flip chip module to the conductive traces;

attaching a wire bond module to the flip chip module;

wire bonding the wire bond module to the leads; and

further encapsulating the flip chip module and the wire bond module in a second encapsulant.

10. The method as claimed in claim 6 further comprising:

conductively bonding a flip chip module to the conductive traces;

attaching a wire bond module to the flip chip module, the wire bond module having a substrate conductively connected to the leads;

encapsulating the wire bond module in a configured encapsulant exposing an exposed portion of the substrate; and

bonding a further flip chip module to the exposed portion of the substrate.

11. An integrated circuit packaging system comprising:

leads

a paddle;

a first encapsulant molded between the leads and the paddle, the first encapsulant

thinner than the leads;

a non-conductive layer over the paddle; and

conductive traces each having a side, the side directly on the lead, the first encapsulant, and the non-conductive layer.

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

a first module attached to the conductive traces; and

a second encapsulant encapsulating the first module.

13. The system as claimed in claim 11 wherein:

the non-conductive layer has an opening therein over a portion of the paddle; and

further comprising:

a first module conductively bonded to the conductive traces on the non-conductive layer and to the paddle through the opening in the non-conductive layer.

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

a first module conductively bonded to the conductive traces;

a second module attached to the first module;

bonds conductively bonding the second module to the leads; and

a second encapsulant encapsulating the first module and the second module.

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

a first module conductively bonded to the conductive traces;

a second module attached to the first module, the second module having a substrate conductively connected to the leads;

a configured encapsulant encapsulating the second module and exposing an exposed portion of the substrate; and

third module conductively bonded to the exposed portion of the substrate.

16. The system as claimed in claim 11 wherein:

the first encapsulant is coplanar with the top and bottom surfaces of the paddle; and

the conductive traces are straight or bent on the first encapsulant or the non-conductive layer.

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

a flip chip module conductively bonded to the conductive traces; and

a second encapsulant encapsulating the flip chip module.

18. The system as claimed in claim 16 wherein:

the non-conductive layer has an opening therein over a portion of the paddle; and

further comprising

a flip chip module conductively bonded to the conductive traces on the non-conductive layer and to the paddle through the opening in the non-conductive layer.

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

a flip chip module conductively bonded to the conductive traces;

a wire bond module attached to the flip chip module;

bond wires conductively connecting the wire bond module to the leads; and

a second encapsulant encapsulating the wire bond module and the flip chip module.

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

a flip chip module attached to the conductive traces;

a wire bond module attached to the flip chip module and having a substrate conductively connected to the leads;

a configured encapsulant encapsulating the wire bond module and exposing a portion of the substrate; and

a further flip chip module bonded to the exposed portion of the substrate.
